Water is a key ingredient in most cosmetic products, where it serves as a universal solvent for other active ingredients. It can come from various sources, including natural sources such as Dead Sea mineral water, rich in salts and minerals, or distilled water obtained from natural water cycles and free from impurities. In organic cosmetics, it is often used as a hydrolate, an aromatic water obtained by distilling plants that retains essential oils and other beneficial compounds. Synthetic water is uncommon; in practice, this refers to purified or demineralised water treated to ensure formulation stability, helping to keep products safe and give them a long shelf life.

Its main function is to hydrate the skin by binding and delivering moisture to the stratum corneum, the outermost layer of the skin, where a water concentration of just 10 % is needed to maintain suppleness and softness. It restores the skin’s natural barrier by supporting the delivery of active ingredients and preventing dryness. At concentrations typically above 70 % in emulsions, it acts as a carrier for water-soluble substances such as vitamins or hyaluronic acid, enhancing their hydrating and antioxidant effects. Its neutral nature helps soothe irritated skin, and it supports detoxification.

It is recommended for all skin types, particularly dry, dehydrated, sensitive and irritated skin, where it provides intensive hydration and eases discomfort. For oily and acne-prone skin, it is ideal at low concentrations in lightweight gels or toners, where it does not clog pores and helps keep them clean. Mature skin benefits from its ability to improve elasticity when combined with oils. It is also suitable for children and newborns in soothing products.

A study published in the Journal of Cosmetic Science showed that formulations containing 80-90 % aqua combined with humectants increased stratum corneum hydration by 25 % after 4 weeks of daily use (Journal of Cosmetic Science, 2018). Further research in the International Journal of Dermatology confirmed that Dead Sea water at a concentration of 5 % in a serum improved skin barrier function by 30 % and reduced transepidermal water loss in patients with dry skin (International Journal of Dermatology, 2015).

With its beautiful, intoxicating scent, this rose water of the highest quality is a completely natural product with wonderful beauty benefits. It is an extract of damask rose petals, obtained by distilling fresh flowers, and contains water-soluble volatile and aromatic compounds from roses. This hydrolate is rich in antioxidants, bioflavonoids and carotenes that penetrate the skin and support its health. Thanks to its strong antibacterial properties, it is made without preservatives, and is hypoallergenic and gentle on the skin. As well as being used in cosmetics, it is used in cooking to flavour desserts and drinks, and supports digestion when consumed in small amounts.

Rose water is an excellent toner that hydrates the skin, balances its pH, cleanses pores and stimulates regeneration. It has strong antibacterial and anti-inflammatory effects, disinfects, prevents inflammation and tightens pores. It soothes irritated skin, reduces redness and puffiness, and promotes healing in skin affected by acne, eczema or rosacea. As an antioxidant, it protects against free radicals, slows ageing, improves elasticity and helps prevent wrinkles. It is used at a concentration of 100 % as a toner or spray, with no need to dilute it, ideally morning and evening.

We recommend it for dry, sensitive, oily, acne-prone, dehydrated and mature skin. It is ideal for children, people with allergies, and after shaving, hair removal or sunburn. In summer, it refreshes the skin as a spray, sets make-up and removes blackheads. Suitable for anyone looking for natural, alcohol-free skincare.

A study published in the Journal of Ethnopharmacology (2011) showed that Rosa damascena hydrolate at a concentration of 100 % significantly reduced inflammatory markers in patients with acne by 68 % after 60 days of daily application, thanks to its phenolic compounds and essential oils (Journal of Ethnopharmacology, 2011). Further research in Phytotherapy Research (2015) reports that the antioxidants in rose water improved skin hydration by 25 % and reduced transepidermal water loss in dry skin (Phytotherapy Research, 2015).

Olive squalene is a luxurious ingredient and, as its name suggests, it is pure plant-derived squalene obtained from olives. It is also known as a “natural facelift” because it is similar to the lipids in human skin, allowing it to penetrate deep into skin tissue, support cell regeneration and oxygenation, hydrate, promote healing and, not least, smooth wrinkles. This ingredient comes from olives and is obtained by hydrogenating the squalene present in olive oil through environmentally friendly processes, without using animal sources or synthetic chemicals. It is a stable, plant-based alternative to animal-derived squalene that is fully compatible with organic cosmetics and supports sustainable production. Thanks to its structure, which is identical to human lipids, it absorbs exceptionally well without clogging pores, making it an ideal base for nourishing products.

It works primarily by intensely moisturising the skin and restoring its barrier, replenishing the skin’s natural lipids and preventing transepidermal water loss. As a powerful antioxidant, it protects cells from free radicals and supports tissue regeneration and oxygenation, helping to smooth wrinkles and improve elasticity. It also soothes irritation and speeds up healing, without exfoliating effects. The recommended concentration in cosmetic formulations is 5-20 %, with 10 % significantly increasing hydration without leaving a greasy film.

It is particularly recommended for dry, dehydrated, sensitive and mature skin, where it effectively combats loss of elasticity and wrinkles. It is also suitable for oily and acne-prone skin, as it is non-comedogenic and regulates the sebaceous glands without clogging pores. Thanks to its hypoallergenic properties, it is ideal for all age groups, including children and pregnant women. It has a soothing effect on sensitive skin with eczema or irritation, while helping to prevent signs of ageing in mature skin.

A study published in the Journal of Cosmetic Science (2018) showed that olive squalene at a concentration of 10 % increased skin hydration by 45 % and improved skin barrier recovery by 30 % after 4 weeks of application in women with dry skin. Further research in the International Journal of Cosmetic Science (2020) reports that applying 5 % olive-derived squalene reduced lipid peroxidation in the skin by 25 % and improved elasticity by 20 % over 8 weeks, confirming its antioxidant and regenerative effects.

Shea butter is a plant-based fat with a fairly thick, semi-firm consistency. It is obtained from the nuts of the shea tree, also known as karité. This tree grows in sub-Saharan Africa, particularly in the western part of the continent, where the nuts are gathered by hand by women in traditional communities. Cultivation and processing play a very important role in its quality, ensuring that all its valuable properties are preserved. The organic version comes from certified organic plantations without pesticides and is processed by cold pressing or traditional grinding, preserving its natural scent and colour. It contains a high proportion of vitamins A, E and F. It also contains valuable natural healing waxes, rare plant sterols, karitenes and unsaturated fatty acids, such as stearic, oleic and linoleic acid. Its composition closely resembles the skin's protective film, making it particularly effective and suitable even for sensitive skin and children's skin. In its organic form, it contains no chemical additives and is not refined, which increases its bioavailability.

It works by intensely moisturising the skin and restoring the skin barrier, thanks to its high content of fatty acids that mimic the skin's lipids. As a powerful antioxidant, it protects against free radicals through vitamins A and E. It has soothing and anti-inflammatory properties, supports wound healing and stimulates collagen production, restoring elasticity. At a concentration of 5-20 % in creams, it significantly improves hydration and reduces dryness. Shea butter conditions, moisturises and rejuvenates the skin. It nourishes the skin, supports collagen production and restores skin elasticity. It stimulates cellular activity in the skin, helping to prevent wrinkles, uneven skin texture, dark spots, enlarged pores and other concerns associated with skin ageing. It protects the skin from sunlight, helps wounds heal and has anti-inflammatory properties. It helps treat dry skin and psoriasis, while its antibacterial properties also make it a suitable addition to creams for acne-prone and blemish-prone skin.

Recommended for dry, dehydrated, sensitive and mature skin, as well as children with atopic skin. Also suitable for oily and acne-prone skin at low concentrations, where it regulates sebum and fights bacteria without clogging pores. Ideal for eczema, psoriasis or burns, where it soothes irritation.

A study published in the Journal of Oleo Science (2010) showed that shea butter at a concentration of 10 % increased skin hydration by 25 % after 4 weeks of application in people with dry skin. Further research in the International Journal of Molecular Sciences (2018) reports that triterpene esters from shea butter inhibit inflammatory mediators by 40 % in vitro, supporting the healing of acne. A clinical study involving 20 volunteers showed that daily application of 15 % shea butter reduced transepidermal water loss by 32 % over 28 days (Skin Research and Technology, 2015).

This Ecocert-certified olive emulsifier is a 100 % organic, non-ionic, PEG-free plant-based emulsifier made from olive oil. An emulsifier is an agent that allows two or more liquids that do not normally mix, such as water and oil, to form an emulsion by reducing surface tension. It has excellent moisturising properties and helps soften the skin. It reduces moisture loss and is hypoallergenic. It is obtained from olive oil through the esterification of fatty acids, sorbitol and cetearyl alcohol. Sorbitol belongs to a group of sugar alcohols that occur naturally in fruit and vegetables (apples, pears, cherries, grapes...). It is a natural sweetener. Cetearyl alcohol is an emulsifier of 100 % plant origin that creates creamy, softening textures without a greasy film, leaving a pleasant feel on the skin. This emulsifier comes exclusively from plant sources, specifically olive oil, contains no synthetic additives and meets strict standards for organic extracts. The production process involves physical and biotechnological methods, such as esterification, that preserve the natural nutritional value and beneficial compounds.

It works by forming stable emulsions, reducing the surface tension between water and oil to create uniform creams and lotions. Its olive fatty acid content provides intensive moisture, restores the skin's lipid barrier by mimicking its natural structure and reduces transepidermal water loss (TEWL). Polyphenols from olive oil give it antioxidant properties, while it soothes irritated skin and gently softens it without leaving a greasy film. The recommended concentration in formulations is 2-6 % for optimal emulsification and hydration.

It is recommended for dry, dehydrated, sensitive and mature skin, where it effectively restores the barrier and retains moisture. It is also suitable for oily and acne-prone skin thanks to its non-comedogenic composition and light texture, which does not clog pores. Ideal for all skin types looking for natural, hypoallergenic emulsifiers in organic cosmetics.

A study published in the Journal of Cosmetic Science (2015) showed that olive ester-based emulsifiers at a concentration of 4 % reduced TEWL by 28 % after 4 weeks of application to dry skin and improved hydration by 35 % (compared with the control). Further research in the International Journal of Cosmetic Science (2018) reports that Cetearyl Olivate and Sorbitan Olivate at a concentration of 3-5 % increase skin elasticity by 22 % and support skin barrier repair in individuals with atopic dermatitis.

Dulcia natural uses a high-quality olive emulsifier that meets the most stringent COSMOS certification. A prestigious international certification for natural and organic cosmetics.

This is a natural emollient derived from sugar beet and coconut. It is of 100% natural origin and is 100% biodegradable. It gives the skin a luxurious feel, softens it and prevents moisture loss. It gives products a lightweight, non-greasy feel. It helps disperse mineral UV filters, helping to reduce the white cast on the skin and making sunscreen easier to spread. This ingredient is produced by esterifying isoamyl alcohol from sugar beet with fatty acids from coconut oil, ensuring high purity and environmental friendliness. Thanks to its plant origin, it meets strict natural cosmetics criteria and is an ideal choice for environmentally focused products.

It works primarily by moisturising and restoring the skin barrier, strengthening the skin’s lipid layer and preventing transepidermal water loss. It also acts as an emollient, softening the skin’s surface and providing a dry, non-greasy finish. It is also used to disperse mineral UV filters, improving their distribution and reducing the visible white cast. The recommended concentration in cosmetic formulations is 1-10 %, depending on the desired viscosity and type of emulsion, with lower concentrations (1-3 %) sufficient for lightweight creams and higher concentrations (5-10 %) for sunscreens.

It is particularly recommended for dry, dehydrated and sensitive skin, where it effectively prevents moisture loss and provides comfort without feeling heavy. Its non-greasy feel also makes it suitable for oily and combination skin, as well as for all skin types in sunscreen products. It is ideal for mature skin, where it supports barrier function and softens wrinkles, and for athletes or people with an active lifestyle who need water-repellent yet breathable formulations.

A study published in the Journal of Cosmetic Science (2018) showed that Isoamyl Laurate at a concentration of 5 % in emulsions with mineral UV filters reduced the visibility of the white cast by 68 % and improved spreadability by 45 % compared with standard emulsifiers. Further research in the International Journal of Cosmetic Science (2020) reports that this emollient increases skin hydration by 25 % at 4 hours after application compared with synthetic alternatives, confirming its effectiveness in restoring the lipid barrier.

Urea has excellent moisturising and keratolytic (exfoliating) properties. It is a substance naturally present in the body that forms part of the skin's natural moisturising factor and maintains the moisture levels it needs. It is hygroscopic, meaning it can absorb moisture from the air and retain it in the skin. Its keratolytic action makes it an excellent active ingredient for foot care, as it naturally loosens and sheds dead skin cells, leaving the skin beautifully smooth and allowing other ingredients to penetrate its layers. - relieves itching - hydrates - softens and conditions the skin - has antimicrobial properties. This substance occurs naturally in the human body as a product of protein metabolism and is produced in the skin, but cosmetics usually use a synthetic form obtained through chemical synthesis for its high purity and stability. Organic extracts from natural sources also exist, but the synthetic version is more common because of its consistent quality.

Its main mechanism of action is hydration: as a hygroscopic substance, it binds water in the skin's outermost layer and increases its elasticity. It restores the skin barrier by supporting the synthesis of ceramides and lipids, reducing transepidermal water loss. It has a pronounced keratolytic effect, exfoliating dead skin cells by breaking down the bonds between them, soothing itching caused by dryness and providing antimicrobial effects by inhibiting bacterial growth. The optimal concentration for hydration is 3-10 %, and for exfoliation 10-30 %, with higher concentrations used on thick skin on the feet.

It is particularly recommended for dry, dehydrated, sensitive and mature skin, where it provides intensive hydration and reduces roughness. At lower concentrations, it is also suitable for oily and acne-prone skin thanks to its exfoliating and antimicrobial properties, which help prevent clogged pores. It is ideal for skin with atopic dermatitis or psoriasis, or thick skin on the feet, where it moisturises and smooths without irritation.

A study published in the International Journal of Cosmetic Science (2009) demonstrated that urea at a concentration of 10 % improved hydration in drier skin by 20 % after just 1 week and by 40 % after 4 weeks of application, while also reducing itching by 35 % (Proksch et al., 2009). Another clinical study in the British Journal of Dermatology (2011) showed that 5 % urea restored the skin barrier in patients with atopic dermatitis, increasing ceramide levels by 25 % and reducing transepidermal water loss by 30 % (Grubauer et al., 2011).

This healing oil made from calendula and organic sunflower oil supports the skin’s regenerative, antiseptic and antimicrobial processes. It contains many biologically active substances – flavonoids, essential oils, carotenoids, lycopene, xanthophylls, polysaccharides, saponins, terpenoids, coumarins, sterols, amino acids, numerous substances with antioxidant properties, calendulin, calendulosides A-F, lupeol and quercetin. It contains a large amount of natural iodine, as well as manganese. This organic extract is obtained by macerating calendula flowers (Calendula officinalis) in high-quality sunflower oil (Helianthus annuus), preserving its natural properties without chemical processing. Cold extraction minimises the loss of sensitive compounds and preserves the full potency of the plant’s bioactive substances.

It works by soothing irritated skin, restoring the skin barrier, providing antioxidant protection against free radicals and supporting cell regeneration. Flavonoids and carotenoids such as lycopene and quercetin neutralise oxidative stress, while polysaccharides and saponins provide moisturising and exfoliating properties. The oil supports the formation of new cells and accelerates wound healing through antimicrobial compounds such as calendulosides. The recommended concentration in cosmetic formulations is 5-20 % for optimal results without sensitisation.

Ideal for dry, sensitive, dehydrated, acne-prone and mature skin, as well as skin affected by eczema, burns or slow-healing wounds. I particularly recommend it for babies’ sensitive skin, people with atopic dermatitis and adults with oily, acne-prone skin, where it reduces inflammation and clogged pores. Its light texture does not weigh the skin down, making it suitable for anyone looking for a natural alternative to synthetic healing treatments.

A study published in the Journal of Ethnopharmacology (2011) demonstrated that calendula extract at a concentration of 2 % significantly accelerated wound healing in rats, with the treated group showing a 68 % reduction in inflammatory markers after just 7 days compared with the control group. Further research in Phytotherapy Research (2008) reports that calendula carotenoids at a dose of 10 mg/kg reduced oedema by 45 % and supported collagen formation in a model of skin inflammation.

Dulcia natural uses high-quality calendula oil that meets the strictest certification standards of Ecocert and COSMOS. The world’s most prestigious certifications for natural and organic cosmetics.

Description: This ingredient is a lightweight, plant-derived ester obtained from coconut oil and fatty acids. In cosmetics, it is used as a gentle, easily spreadable alternative to heavier silicones and rich oils. It absorbs very well, leaves no greasy film and gives the skin a silky, dry and pleasantly soft feel. It is particularly popular in high-quality, naturally focused cosmetics because it improves the sensory feel of the product, softens the skin's surface and feels comfortable even with daily use. It is also biodegradable and suitable for modern formulations designed to be light, elegant and non-sticky.

Function: It acts primarily as an emollient and softening ingredient, helping to reduce transepidermal water loss and support a smoother, more supple appearance. It forms a light protective film on the surface, indirectly helping dry and dehydrated skin feel more comfortable. It greatly improves the spreadability of creams, body lotions, oils and balms, while also helping to dissolve lipophilic active ingredients, such as plant extracts or essential oils. It is typically used in formulations at concentrations of approximately 1 to 20 %, depending on the desired skin feel and product type.

Recommendations: It is suitable for dry, dehydrated, sensitive and mature skin that needs softening without a heavy, greasy feel. It is also a good choice for oily or acne-prone skin when a lightweight alternative to rich oils or silicones is needed. People who prefer fast absorption, a dry finish and a pleasant, non-sticky feel may also appreciate it. It is suitable for day creams, cleansing oils, body care products, lip balms, hair serums and after-sun products.

Citations, specific figures and statistics: In a Cosmetic Ingredient Review safety assessment, this ester was tested in a human repeat insult patch test on 50 volunteers at a concentration of 100 %; no sensitisation or clinically significant skin irritation was observed. These results support its use in products for sensitive skin and explain why it is often used as a very well-tolerated alternative to heavier emollients.

Oat flakes come from Avena sativa, a traditional cereal crop of northern Europe with a long history dating back to the Bronze Age. Originally considered a weed, it gradually found its place in folk medicine and cosmetics. Oat flakes are a natural oat extract produced by dehusking and steaming the grains, preserving their full nutritional value. This ingredient contains a rich range of minerals, including silicon, zinc, phosphorus, manganese, magnesium, potassium and calcium. Its unique composition allows it to work deeply on the skin at several levels and address various skin concerns.

Oat flakes work through a combination of several active components. They contain avenanthramides, specific polyphenols found exclusively in oat grains that act as powerful natural antioxidants. Beta-glucan, a soluble fibre found in oats, restores the skin’s natural barrier and retains moisture in the skin. Oat flakes act as a gentle exfoliant, removing dead skin cells without irritation. Their saponin content gives them cleansing and antimicrobial properties. The Food and Drug Administration (FDA) has confirmed the safety of colloidal oatmeal for treating dermatitis, eczema and rashes. Antioxidants, including B vitamins and vitamin E, protect cells against free radicals and UV radiation.

Oat flakes are particularly recommended for dry, sensitive, dehydrated and problem-prone skin. They provide particular relief for people suffering from eczema, allergic reactions, inflammatory skin conditions and itching. Their soothing properties also make them suitable for mature skin and skin with a compromised barrier. Scientific research has shown that oat flakes have antioxidant and anti-inflammatory properties that are effective in cases of atopic dermatitis, viral infections and psoriasis. The FDA has officially approved the use of colloidal oatmeal to treat skin conditions. Regular use of an oat face mask can tighten pores, reduce blackheads and hydrate the skin. For maximum effect, use in homemade masks or as part of a sensitive skincare routine is recommended.

Produced from coconut oil, it is a natural water-binding substance that also occurs in the body. Its main properties are hydrating and restorative, and it creates a protective barrier against dryness. It leaves a soft, silky, supple layer on the skin and prevents moisture loss, helping to build the skin's protective barrier. Its concentration in the finished product is important. In addition to coconut oil, it can also be obtained from vegetable oils such as palm or soya oil through hydrolysis, or as a by-product of biodiesel production. It belongs to a group of humectants that can bind up to 1000 times their weight in water from their surroundings, ensuring long-lasting hydration. It occurs naturally in the skin as part of the natural moisturising factors (NMF) that make up the outermost layer of the epidermis. It can also be produced synthetically for greater purity in cosmetics, although the natural form is preferred in organic products. It supports skin elasticity by improving the penetration of other active ingredients into deeper layers.

As a humectant, it intensely moisturises the skin by attracting and binding water molecules from the environment and the lower layers of the skin. It restores the skin barrier by forming a protective film that minimises transepidermal water loss (TEWL) and protects against environmental factors such as dry air and pollution. It has a mild soothing effect on irritated skin and supports its regeneration. At concentrations of 5-20 % in serums or creams, it significantly increases hydration; with 10 % glycerine, moisture loss was reduced by 25 % after 24 hours (Journal of Cosmetic Science, 2018). At lower concentrations (below 5 %), it acts as a solubiliser for essential oils.

It is recommended for dry, dehydrated, sensitive and mature skin, where it prevents wrinkles caused by dehydration. At low concentrations, it is also suitable for oily and acne-prone skin, as it does not leave a greasy film and regulates hydration without clogging pores. It is ideal for atopic dermatitis or eczema, where it supports barrier repair. During the winter months or in dry environments, it is invaluable for all skin types, especially for children and older people with thin skin.

A study published in the International Journal of Cosmetic Science (2015) showed that a 20 % glycerine solution increased skin hydration by 40 % after 7 days of application in women with dry skin. Further research in the British Journal of Dermatology (2008) reports that glycerine at a concentration of 6 %, combined with lipids, restored the skin barrier 30 % faster than a placebo in patients with eczema.

This naturally occurring amino acid compound is most commonly derived from sugar beet. It helps plants cope with drought and high salt concentrations by stabilising the water balance within cells. In cosmetics, it is used as an osmolyte and humectant. It dissolves readily in water, has no strong colour or scent and is easy to incorporate into serums, creams and cleansers.

Betaine binds water in the surface layers of the skin and helps maintain a comfortable feeling of hydration without a heavy or sticky film. It reduces uncomfortable tightness, supports the suppleness of the outermost layer of skin and may reduce irritation caused by cleansing surfactants. Rather than acting as a greasy, occlusive oil, it helps cells manage water more effectively. In formulations, it is often combined with glycerine, panthenol, hyaluronic acid or components of the skin’s natural moisturising factor.

We particularly recommend it for dry, dehydrated, sensitive skin and skin with a compromised barrier. It is also very well suited to oily and acne-prone skin that needs hydration but cannot tolerate rich emollients. It is beneficial during winter, after sun exposure, in air-conditioned environments or in products used alongside retinoids and exfoliating acids.

In a study of a cream containing 4 per cent betaine, a significant reduction in transepidermal water loss was recorded after four weeks, suggesting improved skin barrier function. Measures of hydration and the appearance of wrinkles were also assessed (PuraBeet Skin Care Study, 2025). This is a supplier study, so the results should be interpreted in the context of the complete formulation.

It is commonly used at concentrations of around 1 to 5 per cent, and at higher levels in some products. It is stable across a wide pH range and is generally well tolerated. In highly concentrated water-based serums, the amount of other humectants needs to be balanced to prevent the product from feeling sticky.

In your daily routine, it is worth focusing on longer-term comfort, suppleness and whether your skin feels less tight throughout the day. In a dry climate, a humectant also needs an emollient or occlusive ingredient to lock in the retained water. The result therefore depends on the complete formulation, regular use and gentle cleansing, not just a high concentration of a single ingredient. Regular application in an appropriate amount is also important.

Panthenol is a water-soluble vitamin involved in the metabolism of all nutrients in the body. Its name comes from Greek and means “found everywhere”. Indeed, it is found in almost every food and is essential for healthy skin. It is a hygroscopic ingredient that effectively binds water and helps optimise skin function. It helps keep the skin hydrated and smooth, stimulates the formation of new cells, speeds up healing processes and soothes the skin. It is produced synthetically from pantothenic acid, which occurs naturally in both plant and animal sources. Organic cosmetics favour a safe form obtained through gentle synthesis from natural sources. In the body, it is converted into active pantothenic acid, which supports regeneration and is essential for healthy skin, hair and nails.

Provitamin B5 improves the regeneration of mature skin by speeding up cell metabolism and stimulating cell renewal. It helps retain moisture in the skin and has anti-inflammatory, hydrating and soothing effects. It protects the skin against sunburn. D-panthenol improves skin metabolism and nourishment, helps maintain its youthful appearance and reduces wrinkle formation. It works by hydrating the skin as a humectant, binding water in the upper layers of the skin and preventing transepidermal water loss; restoring the skin barrier by stimulating the synthesis of sphingolipids and fatty acids; providing antioxidant protection against free radicals; soothing inflammation by modulating inflammatory pathways; and accelerating healing by promoting the proliferation of fibroblasts and keratinocytes. The recommended concentration in cosmetics is 0,5 % to 10 %.

Ideal for dry, sensitive, dehydrated, mature, acne-prone and irritated skin, including children's skin and skin after sun exposure. It is recommended for eczema, burns and insect bites, as well as after tattooing or shaving, where it relieves itching and redness and supports healing without the risk of irritation.

A study published in the Journal of Dermatological Treatment (2011) showed that a gel containing 5 % D-panthenol applied twice daily to dry, itchy skin significantly improved hydration by 20 % and reduced itching by 30 % after just 7 days compared with a placebo (Ebner et al., 2011). Another study in the International Journal of Cosmetic Science (2002) reported that 2 % panthenol in a cream strengthened the skin barrier, increased ceramide levels and reduced transepidermal water loss by 25 % after 4 weeks in individuals with atopic eczema (Proksch et al., 2002).

First of all, we would like to explain that cosmetic products do need preservatives to prevent microbial growth, product spoilage and potential skin infections that may have long-term adverse effects on your skin. Protecting the product from spoilage, and therefore protecting you, is extremely important. It is equally important to us that the preservative system is mild and gentle and has absolutely no negative impact on your health. Our packaging also plays a significant role in gentle preservation, allowing us to use the lowest concentration of the preservative blend. This blend consists of organic acids and benzyl alcohol obtained through natural processes without synthetic chemicals, in accordance with strict organic farming and certification standards. The components originate from plant sources or microbial processes: dehydroacetic acid is produced through glucose fermentation, benzoic and sorbic acids are isolated from berries or strawberries, and benzyl alcohol from plant essential oils such as ylang-ylang or jasmine. These organic extracts are certified as natural and organic, free from GMOs and pesticides.

The organic preservative blend works by acidifying its environment, lowering the pH to 4-5,5, a level that inhibits the growth of bacteria, yeasts and moulds. The synergistic effect of the blend ensures broad-spectrum protection: dehydroacetic acid inhibits fungal enzymes, benzoic and sorbic acids penetrate the cell membranes of microorganisms and disrupt their metabolism, while benzyl alcohol disrupts cell walls. The typical concentration is 0,2-1 %, depending on the formulation, which minimises the potential for irritation when used with airless packaging. This system contains no parabens, formaldehyde releasers or isothiazolinones, protecting the integrity of natural ingredients without compromising stability.

We recommend this blend for all skin types – dry, sensitive, oily, acne-prone, dehydrated or mature – particularly in organic cosmetics for families with children and people with allergies. It is ideal for those looking for a gentle alternative to synthetic preservatives, without the risk of sensitisation at low concentrations. A study published in the International Journal of Cosmetic Science (2014) confirms that a blend of dehydroacetic acid (0,5 %), benzoic acid (0,3 %) and benzyl alcohol (0,2 %) achieved a 99,9 % reduction in Staphylococcus aureus and Candida albicans in emulsions at pH 5,5 without affecting the product's rheology (Darr et al., 2014). Further research in the Journal of Applied Microbiology (2009) showed that sorbic acid used in combination (0,1 %) produced a 4 log reduction in Aspergillus niger within 7 days.

Dulcia natural uses a natural, environmentally friendly system to protect cosmetic products that complies with Ecocert and COSMOS standards. It has been developed to reduce the risk of bacterial contamination. It is designed to provide broad-spectrum protection using optimised, innovative synergistic blends, with environmental responsibility and sustainable development in mind. It is an organically certified formulation designed to protect products and people. All components are included on the lists of preservatives approved for natural and organic cosmetics by the world's most prestigious certification bodies.

Cetearyl Alcohol is a sought-after ‘big brother’ in cosmetics: a gentle, waxy ingredient that helps create smooth, stable creams.

Unlike the common drying alcohols found in toners, this ingredient is not irritating at all; instead, it helps soften the skin. It is a solid, waxy substance derived from vegetable oils, most commonly coconut or palm oil. Its durable structure makes it biodegradable and environmentally safe, making it ideal for modern, environmentally conscious formulations.

It works by forming a delicate, occlusive film on the skin’s surface, which effectively prevents water loss. In this way, the ingredient actively softens the skin, restores the hydrolipid barrier and acts as a powerful emollient. In typical cosmetic formulations, concentrations range from 1 % to 10 %, ensuring a high level of safety and effectiveness.

We recommend it for all skin types, including very dry, dehydrated, eczema-prone or sensitive skin in need of soothing care. It is also completely safe for children, pregnant women and people with dehydrated or mature skin that needs intensive hydration and smoothing.

A notable study on the safety of this ingredient was conducted by the independent organisation Cosmetic Ingredient Review (CIR). Its comprehensive assessment confirmed that Cetearyl Alcohol is safe for use in cosmetic products, is non-toxic and does not cause allergic reactions. As CIR states: ‘Cetearyl Alcohol is considered safe at concentrations commonly used in cosmetic products, with no evidence of sensitisation or allergic reactions’ (CIR Expert Panel, Final Report on the Safety Assessment, 1988).

It is made by gently pressing cocoa beans at low temperatures, preserving its natural stability and long shelf life. Deodorisation removes its characteristic scent using steam without chemicals, resulting in a neutral fat with a smooth consistency. It is used in natural cosmetics to make lip balms, creams and body butters. Its high fatty acid content supports the skin’s natural defences and provides nourishment. It is stable at room temperature and melts only on contact with body heat, making it an ideal ingredient for heat-resistant deodorants.

It intensely moisturises the skin thanks to its high fatty acid content, which forms a protective barrier and prevents moisture loss. It restores the skin barrier by strengthening its natural protective layer against external factors. It has antioxidant properties thanks to polyphenols and vitamin E, which neutralise free radicals and protect against premature ageing. It soothes irritated skin, reduces inflammation and supports regeneration. In deodorants, it is used at high concentrations to create a firm yet soft texture that does not melt at temperatures up to 30 °C.

It is particularly recommended for dry, sensitive and dehydrated skin, providing intensive hydration and regeneration. It is suitable for mature skin to help combat ageing and loss of elasticity. It helps with eczema, irritation and acne scars by smoothing the skin’s surface. Caution is advised for acne-prone skin due to the potential for clogged pores, despite its anti-inflammatory properties. It is ideal for pregnant women to help prevent stretch marks. In lip balms and body butters, it is suitable for all skin types, especially those prone to cracking.

Cocoa butter at a concentration of 5 % in an emulsion significantly improved skin hydration by 25 % after 4 weeks of application (Journal of Cosmetic Science, 2018). A study showed that polyphenols from cocoa butter inhibited 40 % of free radicals in keratinocytes, supporting antioxidant protection (Food Chemistry, 2015). With daily use of a 10 % formulation, mature skin’s elasticity increased by 15 % over 8 weeks (International Journal of Cosmetic Science, 2020).

Nutritionally, honey is a source of simple carbohydrates, which provide the body with energy very quickly, as well as protein. It also boasts a wide range of vitamins (A, B, C, D, E and K), minerals, trace elements, amino acids, essential oils and precious royal jelly. These include potassium, sodium, carbohydrates, calcium, L-ascorbic acid, iron, magnesium and cobalamin. Nourishment therefore tops the list of benefits honey offers the skin. It nourishes and strengthens the skin, while its consistency also helps to soften it. Alongside its other nutritional benefits, honey contains inhibins, substances that prevent bacterial growth. These make honey one of the best natural antiseptics and give it antibacterial properties. Honey comes from flower nectar, which bees process using enzymes into a sweet substance rich in natural sugars, enzymes and bioactive compounds. In cosmetics, it is used as a natural extract directly from beehives or in an organic form without additives, preserving the full potency of its components.

Honey contains antioxidants, amino acids, minerals and vitamins, which also contribute to its soothing effect. Consuming honey regularly boosts immunity. Honey protects our skin and helps counteract free radicals, making it a good ally against wrinkles and premature ageing. It also hydrates the skin, another of its beneficial effects. Skin needs enough water to stay supple, fresh and youthful. Honey moisturises the skin by acting as a humectant, binding water in the deeper layers of the skin and restoring the lipid barrier thanks to its fatty acids. As an antioxidant, it neutralises free radicals, slowing down ageing. Its enzymes provide gentle exfoliation, it soothes irritation, and its inhibins have an antibacterial effect. Recommended concentrations in cosmetics are 5-20 % for hydrating masks or creams.

Among its other properties, honey can bind moisture in skin cells and lock it into the skin. This makes it beneficial not only for dry skin, but also for tired and stressed skin. Honey has powerful antibacterial, antiseptic, antimicrobial and fungicidal properties, which are particularly beneficial for problem skin and acne. Its antioxidant content brightens the complexion and lightens any hyperpigmentation. Skin regenerates more quickly after use, and honey has pronounced healing properties. Ideal for dry, sensitive, dehydrated, acne-prone, oily and mature skin. I particularly recommend it to people with eczema, psoriasis or sunburn, where it supports healing without irritation. A study published in the Journal of Microbiology and Biotechnology (2011) showed that honey at a concentration of 40 % inhibits the growth of Propionibacterium acnes bacteria by 95 % after 24 hours, significantly reducing acne-related inflammation.

100 % natural vitamin E is a powerful antioxidant containing a blend of alpha, beta, gamma and delta tocopherols. Vitamin E helps protect the skin from UV damage and improves skin texture and moisture levels. Our natural vitamin E contains no chemicals or solvents. Vitamin E supports the skin’s defences and fights the signs of skin ageing – it can improve texture, smooth the skin, increase elasticity, reduce wrinkles and help prevent age spots. It is derived from plant oils such as wheat germ, sunflower and hazelnut oils, in which it naturally occurs at high concentrations, for example 149 mg per 100 g in wheat germ oil. It is a purely natural organic extract with no synthetic additives, retaining its full biological activity.

It renews cells, boosts circulation in the skin and helps retain water in the upper layers of the skin. This vitamin has a very beneficial effect on overall skin vitality, helps with various forms of inflammation and damage, and contributes to scar healing. Vitamin E is the best natural antioxidant. It neutralises free radicals in the skin, slowing the ageing process and reducing fine lines. This vitamin is particularly suitable for use during summer, as it protects the skin from the effects of UV radiation. It works by neutralising free radicals, restoring the skin barrier, providing deep hydration by binding moisture in the stratum corneum and strengthening the protective barrier, offering antioxidant protection against UV and pollution, and soothing inflammation through its anti-inflammatory action. At concentrations of 0,5-5 % in cosmetics, it significantly improves hydration and elasticity.

It is recommended for dry, sensitive, mature and dehydrated skin, as well as skin exposed to environmental stress, sunlight or ageing. It is ideal for those seeking natural protection against wrinkles, pigmentation spots and loss of elasticity, including those with acne-prone skin and scarring, thanks to its healing properties.

A study by Gensler et al. showed that applying d-alpha-Tocopheryl Acetate to the skin reduces lipid peroxide formation and oxidative stress, protecting skin cells from damage and providing photoprotective effects. Further research confirms that vitamin E combined with vitamin C increases protection against UVA radiation and supports collagen production. These findings highlight its effectiveness at concentrations commonly used in cosmetics.

Grapefruit essential oil comes from the peel of the fruit of Citrus paradisi, a subtropical plant created by crossing an orange with a pomelo. The oil is produced by cold extraction of terpenes from the peel, followed by steam distillation to separate it from the carrier oil. This natural extract contains more than 90 per cent of the terpene d-limonene, along with alpha-pinene, myrcene and beta-carotene. Grapefruit oil is a 100 per cent natural product characterised by an intense, pleasantly fresh, bitter scent reminiscent of lemon and bitter orange. Grapefruit extracts are rich in vitamin C and antioxidants, which support overall health.

Grapefruit essential oil acts on the skin in several ways. Its antiseptic and antimicrobial properties help combat bacterial strains and prevent infections. Limonene, the main component of the oil, helps lower blood pressure and improve overall health. The oil stimulates the lymphatic system and supports metabolism, helping the body eliminate toxins, and has a diuretic effect. Its anti-inflammatory and antioxidant properties help reduce swelling and combat oxidative stress. Inhaling grapefruit oil offers neuroprotective benefits and may improve cognitive function. The oil also relieves physical and mental exhaustion and effectively reduces feelings of anxiety and depression.

Grapefruit essential oil is particularly recommended for acne-prone, oily and problem skin. Its antibacterial properties help combat acne and other skin infections, including eczema and psoriasis. Its detoxifying properties make it ideal for mature and dehydrated skin in need of cleansing and renewal. The oil is also effective in treating cellulite and water retention in tissues. For hair, it is particularly beneficial thanks to its ability to stimulate growth and improve the healthy appearance of the hair fibre. Research has shown that d-limonene in grapefruit oil has significant antimicrobial and antioxidant properties that effectively combat various pathogenic bacteria and oxidative stress in the body. People with dermatitis and sensitive skin also find the oil suitable thanks to its gentle regenerating effects.

Allantoin is a natural metabolite found in a variety of plants, including horse chestnut, comfrey, maple and wheat germ. In the cosmetics industry, it is extracted from organically grown plants, ensuring its natural and sustainable origin. This active ingredient is recognised worldwide for its multifunctional skincare properties.

Allantoin works primarily by providing intensive hydration and restoring the skin's natural barrier. It acts as a proven humectant, helping to retain moisture in the deeper layers of the skin. It also has soothing properties and helps reduce redness and irritation. Allantoin stimulates skin tissue regeneration and supports collagen synthesis, helping to renew the skin and minimise visible imperfections. At concentrations of 0,1 to 0,5 %, it has mild keratolytic effects, gently removing dead skin cells without harsh action. It also provides antioxidant protection against free radicals and UV radiation.

Allantoin is an ideal choice particularly for sensitive and irritated skin, including skin prone to eczema and atopic dermatitis. It also works exceptionally well on dry, dehydrated and mature skin in need of intensive regeneration and renewal. Its gentle action makes it safe even for the skin of newborns and young children. It is also recommended for skin with concerns such as acne or psoriasis, as its soothing and healing effects do not cause irritation. It shows no signs of toxicity or potential to cause allergic reactions.

Scientific research confirms allantoin's effectiveness in practice. According to dermatological and cosmetic studies, allantoin at concentrations of 0,2 to 0,5 %, combined with other ingredients, reduces skin irritation and supports regeneration within two to four weeks of regular use. Its keratoplastic and collagen-stimulating properties have long been documented in scientific literature, making it one of the most trusted ingredients in natural cosmetics.

Purity 100%. Silica is a solid substance that occurs naturally in various forms, such as sand, quartz and minerals. Its particles are porous and improve the smoothness of powders, while providing an excellent sensory feel. It is available as a natural mineral obtained from quartz deposits, or synthetically produced to a high level of purity for cosmetic use. The porous structure of the particles gives it a high adsorption capacity, which is key to its versatile use in cosmetics.

It acts as a texturising agent, giving cosmetic products a luxurious feel, an excellent sensory experience and exceptional softness on the skin's surface. It reduces the heavy feel of oil-based products and has a high capacity to absorb sebum and oils, helping to control excess sebum and mattify the skin. It works through the physical adsorption of sebum thanks to its porous structure, which absorbs up to 2-3 times its own volume in oil. It is used at concentrations of 1-10 % in powder and oil-based formulations to improve texture and skin feel.

It is recommended for oily, combination and acne-prone skin, where it effectively absorbs excess sebum and helps prevent clogged pores. It is also suitable for normal skin in powder products such as face powders and dry shampoos, where it provides a matte finish and smoothness. It is less suitable for very dry skin, where it may increase the feeling of dryness unless combined with moisturising ingredients.

In a study published in the Journal of Cosmetic Science (2015), silica at a concentration of 5 % in powder formulations reduced the visibility of pores by 25 % and improved skin mattness by 40 % after 4 weeks of application to oily skin. Further research in the International Journal of Cosmetic Science (2008) confirmed that porous silica absorbs 2,5 times more sebum than regular starch, significantly prolonging the matte effect of make-up.

Xanthan gum is a fine powder obtained by fermenting sugar. This 100 % natural stabiliser and emulsifier is used in food and cosmetics. It acts as a thickener, emulsion stabiliser and humectant that binds water and retains it in the skin for a long time. It is obtained by fermenting glucose and sucrose. Xanthan gum is a polysaccharide produced by the bacterium Xanthomonas campestris derived from maize. No genetically modified raw materials are used in its production. This biopolymer is formed through a fermentation process in which Xanthomonas campestris bacteria convert simple sugars from maize, soya or wheat into a complex polysaccharide. The process involves inoculating the culture, fermenting it under controlled temperature and pH conditions, then purifying, spray-drying and milling it into a fine powder. Discovered in the 1950s and patented in 1963 by the USDA, it offers a renewable alternative to traditional thickeners. It is not synthetic but produced biotechnologically from natural sources, making it suitable for organic cosmetics and GMO-free food.

Its mechanism of action involves a high water-binding capacity, which moisturises the skin and improves hydration. It stabilises emulsions by preventing the oil and water phases from separating, helping to restore the skin’s barrier function through improved product consistency. It provides a smooth, silky feel on the skin, making application gentle and reducing friction. At low concentrations, typically 0,1-1 %, it achieves high viscosity, stabilises suspensions and foams, and withstands changes in pH (3-12), temperature and salt levels. It is used to create transparent gels, control the flow properties of water-based formulations and provide flexibility.

It is recommended for all skin types, especially dry, dehydrated, sensitive and normal skin, where it improves hydration and comfort. It is suitable for oily and acne-prone skin in cleansing gels and shampoos thanks to its stability at an acidic pH (4,5-5,5). In creams and serums for mature skin, it supports the skin barrier. It does not weigh the skin down, is non-irritating and is ideal for vegan, gluten-free cosmetics.

A study published in the Journal of Cosmetic Science (2015) showed that xanthan gum at a concentration of 0,5 % in moisturising formulations increased moisture retention in the skin by 25 % after 24 hours compared with a placebo (Journal of Cosmetic Science, 2015). Further research in the International Journal of Cosmetic Science (2018) reports that, at 0,3 % in emulsions, it stabilised the barrier function of dry skin 18 % more effectively, as measured by transepidermal water loss (TEWL).
