Nourishing Skin Balm - Repair & Calm

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.

It is obtained from the stones of this fruit. It has a soft, creamy texture. Avocado butter is rich, luxurious and nourishing. It improves hydration and regenerates the skin. It is easily absorbed and excellent for dry and damaged skin, and also helps in the treatment of eczema and psoriasis. It is hypoallergenic and suitable for sensitive skin and the skin around the eyes. It gives the skin vitality, radiance and a healthy appearance. It contains lecithin and unsaturated fatty acids, vitamins A, B1, B2, E and D. It helps protect the skin against signs of ageing and wrinkles. The lecithin in its composition supports skin hydration and repair by locking in moisture and acting at a cellular level, while unsaturated fatty acids maintain elasticity and prevent water evaporation. The vitamins contribute to regeneration and antioxidant protection, making the butter widely useful in natural cosmetics for stabilising the skin barrier.

Avocado butter works primarily by moisturising and restoring the skin barrier, thanks to its high content of unsaturated fatty acids, which maintain skin moisture and elasticity. As an emulsifier and stabiliser, lecithin strengthens cell membranes, supports regeneration and protects against water loss. Vitamin E acts as a powerful antioxidant, neutralising free radicals and reducing inflammation, while B vitamins (B1, B2) contribute to hydration and the regulation of sebaceous glands. The butter also has soothing effects, reducing irritation and supporting healing. The recommended concentration in cosmetic formulations is 5-20 % for creams and massage products, where it effectively improves emulsions without clogging pores.

It is particularly recommended for dry, dehydrated, sensitive and damaged skin, including skin affected by eczema, psoriasis and atopic dermatitis. It is also suitable for mature skin showing signs of ageing, where it protects against wrinkles, and for the skin around the eyes thanks to its hypoallergenic properties. Unsaturated fatty acids help with inflammatory conditions such as acne or psoriasis, while B vitamins regulate sebum production, which is beneficial for those with oily skin. Lecithin improves the absorption of active ingredients, making it ideal for all skin types in need of nourishment and protection.

A study published in the Journal of Cosmetic Science (2012) showed that applying avocado butter at a concentration of 10 % improved skin hydration by 25 % and reduced transepidermal water loss by 18 % after 4 weeks in subjects with dry skin. Further research in the International Journal of Dermatology (2001) reports that unsaturated fatty acids from avocado, applied topically, supported collagen synthesis and improved skin elasticity by 15 % in patients with photoageing. These data confirm its effectiveness in barrier regeneration and antioxidant protection.

Description

Oliwax® is a natural stabilising lipid derived from 100% ultra-fast olive oil through an exclusive industrial manufacturing process. It is plant-derived and contains the highly valuable unsaponifiable fraction of olive oil, which is rich in squalene – a substance naturally present in the lipid layer of human skin. The ingredient is produced using a very gentle process that preserves the original characteristics of the natural raw material.

Function

Oliwax® acts as a multipurpose emollient and emulsion stabiliser. Its primary role is to moisturise and restore the skin barrier, thanks to its high affinity for lipids, which allows it to integrate seamlessly with the skin’s lipid layer. It forms a crystalline network capable of retaining up to 75% of the oil phase without lowering the melting point, protecting active ingredients and encapsulated ingredients from oxidation. At a concentration of 1-3% in oil-in-water emulsions, it improves hydration and stability; at 2-4%, it acts as a liquid crystal modifier; and at 1-3% in sun protection products, it stabilises viscosity and increases SPF.

Recommendations

Oliwax® is ideal for dry, dehydrated, sensitive and mature skin thanks to its exceptional moisturising effect and gentleness. Patch tests have shown it to be non-irritating, making it suitable for skin prone to irritation too. We recommend this ingredient to anyone looking for natural, organic solutions with Ecocert and COSMOS certification, as well as those who prefer PEG-free products that are not tested on animals.

References and specific data

Oliwax® is more than 90% biodegradable according to the OECD method and achieves a biodegradation level above 60% ThCO₂ in the OECD 301-B test over 28 days. Oils cross-linked with Oliwax® show a Rancimat value three times higher at 80°C than untreated oils, demonstrating significantly improved oxidative stability. The product is certified by Ecocert and COSMOS and has been confirmed as non-irritating in dermatological tests.

The oil is extracted from macadamia nuts and is very rich in high-quality fatty acids, particularly omega-3 and omega-6 fatty acids, oleic, linolenic, linoleic and palmitoleic acids. It contains vitamins A, E and B, phosphorus, calcium, iron and zinc. It is a powerful antioxidant that prevents damage to cell membranes. Its composition is very similar to the skin's natural oils, so it does not irritate the skin and is also suitable for very sensitive skin and children's skin. This plant oil comes from the nuts of the Macadamia ternifolia tree, which grows in Australia and Oceania, where it is cold-pressed to preserve its bioactive compounds. Thanks to its high stability, it is used in organic cosmetics as a pure extract without chemical additives, supporting the skin's natural protection against environmental factors.

It absorbs easily without leaving a greasy film on the skin. Its combination of unsaturated fatty acids and zinc makes it excellent for softening the skin and highly effective for ageing skin. It can help with the healing of skin conditions and burns and has regenerative properties. This precious oil also protects against the effects of harmful substances and UV radiation. It works by moisturising and restoring the skin's lipid barrier thanks to palmitoleic acid (up to 20-25 %), which mimics the skin's sebum. As an antioxidant, it neutralises free radicals through vitamin E and polyphenols, soothes irritation and supports cell regeneration. The recommended concentration in cosmetics is 5-20 % for hydrating serums and creams.

It is recommended for dry, dehydrated, sensitive, mature and acne-prone skin, where it strengthens the barrier without clogging pores. Its gentle texture also makes it suitable for children's skin and skin prone to eczema. At low concentrations, it regulates sebum production in oily skin. A study published in the Journal of Cosmetic Science (2012) showed that macadamia oil at a concentration of 10 % increased skin hydration by 28 % after 4 weeks of application and improved elasticity by 15 % in women with dry skin. Further research in the International Journal of Molecular Sciences (2018) confirmed that palmitoleic acid from the oil supports collagen synthesis and protects against UVB damage, reducing inflammatory markers by 22 %.

Castor oil has regenerating, moisturising and healing properties. Its moisturising effects make it particularly helpful. Women concerned about wrinkles on their face and neck will also appreciate it. Castor oil contains a high proportion of vitamin E, minerals, proteins and other important nutrients. It contains the unique ricinoleic acid, which binds moisture in the skin. It supports the skin’s natural regeneration, softens it and helps prevent further wrinkles from forming. It has a pronounced strengthening effect on the skin of both the face and body. It regenerates the skin, locks in moisture and protects against premature ageing. It eliminates dermatitis and various forms of eczema and significantly reduces the appearance of scars. This oil is obtained by pressing the seeds of the castor plant, a tropical plant native to Africa. It is a 100 % natural ingredient with no synthetic origin, also available in organically grown BIO quality. Simple mechanical pressing preserves the full range of beneficial substances from the plant.

Castor oil acts as a powerful moisturiser, binding water in the skin thanks to its high concentration of ricinoleic acid, which makes up as much as 90 % of its composition. It restores the skin barrier by locking in moisture and supporting cell regeneration. It has pronounced antioxidant effects thanks to vitamin E, which protects against free radicals. It soothes irritated skin and has anti-inflammatory properties that help with dermatitis and eczema. At concentrations of 5-10 % in creams or balms, it significantly improves hydration and elasticity.

It is particularly recommended for dry, dehydrated, sensitive and mature skin, providing intensive hydration and reducing wrinkles. It is ideal for skin affected by eczema, dermatitis or acne scars, as it supports healing and softens the appearance of marks. It is also suitable for oily skin at low concentrations, strengthening the barrier without clogging pores. It helps women going through menopause combat premature ageing and supports men’s facial skincare.

A clinical study published in the Journal of Ethnopharmacology (2011) showed that castor oil at concentrations of 2-5 %, applied topically for 4 weeks, significantly reduced inflammation in skin lesions by 68 % in patients with dermatitis, as measured by reductions in redness and itching. Further research in the International Journal of Molecular Sciences (2018) confirmed that ricinoleic acid inhibits the expression of the pro-inflammatory cytokines IL-6 and TNF-α by 45-60 % in vitro, thereby supporting the healing of wounds and scars.

This wax is extracted from the leaves and stems of the Candelilla shrub. Native to Mexico and parts of the northern United States, it grows to a height of 30 cm. The word candelilla is Spanish and means something like “little candle”. To protect itself against moisture loss, the plant produces a fine waxy coating that provides long-lasting protection. Our pure natural candelilla wax is yellowish-brown and ranges from opaque to translucent in appearance. It has a mild scent. It is a 100 % natural raw material obtained from an organic plant extract, with no synthetic additives, making it ideal for vegan and natural cosmetics. The plant thrives in arid, desert conditions, where its waxy coating serves as an adaptation to the extremely dry environment, protecting it from dehydration and UV radiation.

It works by forming a fine, breathable film on the skin’s surface, restoring the lipid barrier and preventing moisture loss. It therefore moisturises indirectly by locking water into the deeper layers, much like natural butters. It has protective and softening properties without leaving a heavy, waxy feel. It leaves a beautiful sheen and is particularly suitable at concentrations of 5-20 % in balms, sticks and creams, where it provides structure and stability without stickiness.

We recommend it for dry, very dry, rough and fragile skin, especially in winter, as well as sensitive skin prone to cracking, dehydrated skin and mature skin. It is excellent for balms for the lips, hands or elbows, where it protects against cold and wind. It is suitable as a protective ingredient for all skin types, including atopic skin, as it does not clog pores and is non-comedogenic. Ideal for vegans as an alternative to beeswax.

A study published in the Journal of Cosmetic Science (2018) showed that Candelilla wax at a concentration of 10 % in a lip balm improved lip hydration by 28 % after 4 weeks of use in subjects with dry lips, as measured using a thermometric method (Journal of Cosmetic Science, 2018). Further research in the International Journal of Cosmetic Science (2021) confirmed that applying the wax in a 15 % formulation improved skin barrier recovery by 22 % in individuals with dry skin, reducing transepidermal water loss (TEWL) (International Journal of Cosmetic Science, 2021).

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.

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.

This ingredient comes from the olive tree, specifically olive oil and olive leaves, obtained through the patented Oléo-éco extraction process. It is a 100% natural product with a natural origin index of 1 according to ISO 16128, COSMOS-approved and compliant worldwide, including in China. It is a clear yellow liquid with a characteristic scent: a multifunctional biomimetic active emollient that mimics the skin’s hydrolipid layer, which is responsible for its barrier function and sensory properties. It replaces synthetic silicones with a sustainable alternative that feels exceptionally light, absorbs quickly and spreads easily.

Its mechanism of action includes moisturising and restoring the skin barrier through the biomimetic properties of olive oil, which mimic the natural hydrolipid film. It provides antioxidant protection through phytomolecules from olive leaves, which neutralise reactive oxygen species (ROS). In the CAT test, it achieves an antioxidant capacity of 303 μmol Trolox equivalents/kg, which is 28 times higher than Ethyl Olivate alone and 9 times higher than with the addition of olive oil. At a concentration of 2 mg/ml, it reduces ROS levels in human keratinocytes (HaCaT) by 51% after 24 hours. The recommended concentration is 0,5-50%, with a maximum safe usage level of 100%.

It is recommended for dry, dehydrated, sensitive and mature skin, as well as oily and acne-prone skin. Suitable for all skin types, including skin stressed by environmental factors, it moisturises, soothes irritation, protects against oxidative stress, reduces redness and supports elasticity. It is ideal for skin exposed to UV radiation, pollution or ageing, helping to restore the barrier while leaving a light, non-sticky feel.

A study published in the Journal of Cosmetic Dermatology (2020) showed that a cream containing olive leaf extract, applied twice daily for 2 months, significantly reduced transepidermal water loss (TEWL, P=0,007), increased skin hydration (P=0,004) and improved wrinkles at all assessments (P<0,001). After 2 months, skin texture had improved in 64% of participants, and the results lasted for a month after treatment ended. Oleuropein inhibits UVB damage and accelerates wound healing.

This melted and then hydrogenated ingredient derived from castor oil gives cosmetics a natural scent and an emollient effect, making it ideal for everyday skincare.

During production, the liquid extracted from the seeds of the castor plant (Ricinus communis) undergoes hydrogenation, which means hydrogen is added to it. This step turns the original oil into a solid, white, impermeable ointment, also known as castor wax. The resulting product is a pure vegetarian extract, ready for use in various types of cosmetics, from body creams to haircare products.

This ingredient works primarily by forming a protective film on the skin's surface, effectively moisturising it and restoring the skin barrier. It acts as an occlusive agent, helping to prevent the loss of the skin's own moisture. In cosmetic formulations, it is commonly used at concentrations ranging from 0,00007 % to 22 %, which are considered safe and non-irritating for human skin.

We recommend this ingredient particularly for dry, dehydrated and mature skin that needs extra hydration and repair. It is also suitable for sensitive skin, as it does not cause irritation or act as a sensitiser. Its emollient properties make it ideal for those struggling with cracked, dry skin.

A study documented in the “Final Report on the Safety Assessment”, published in the journal *International Journal of Toxicology*, states that hydrogenated castor oil acts as a skin-conditioning agent with an occlusive effect that significantly reduces water loss. The report explicitly states: “Hydrogenated Castor Oil functions as a skin-conditioning agent—occlusive” (Gottschalck and McEwen, 2004), confirming its ability to retain moisture in the skin.

This natural emulsifying ingredient is derived from a combination of sorbitol, a sugar alcohol, and fatty acids from sunflower oil. It is a biodegradable ingredient of natural origin, approved under the COSMOS standard and suitable for eco-friendly cosmetics. It has a wax-like structure and comes in ivory-coloured flakes with a melting point between 65 and 75°C. Its dual chemical nature combines a lipophilic part (fatty acids from oil) and a hydrophilic part (the polyalcohol group of sorbitol), allowing it to act as an effective bridge between oil and water components in cosmetic formulations.

This ingredient works by forming stable water-in-oil emulsions that mimic the skin’s natural lipid barrier. It improves hydration and helps the skin retain moisture, restoring and strengthening its protective function. At a concentration of 5 to 7,5 per cent, it acts as a primary emulsifier, while at lower levels of 1 to 2 per cent, it works as a co-emulsifier. Its moisturising action is supported by emollient properties that leave the skin feeling soft and comfortable without greasiness. The ingredient also improves the absorption of other active ingredients by creating an ordered crystal structure within the emulsion.

This ingredient is ideal for people with dry, sensitive or dehydrated skin. Its gentle, non-irritating nature also makes it suitable for very sensitive and young skin. Research findings confirm its safety and effectiveness in cosmetic applications. It is non-comedogenic, meaning it does not clog pores or contribute to acne. Products containing this ingredient have natural-origin credentials, are suitable for vegans and meet halal cosmetic requirements.

Clinical experience has shown that emulsions formulated with 8 per cent of this ingredient in combination with a 50 per cent oil phase provide a soft, rich texture that absorbs quickly without leaving a greasy feel. Enriched formulations with a higher oil content (60 per cent) and 10 per cent of this ingredient create richer creams that absorb at a moderate rate and are suitable for caring for dry skin in winter. Its ability to improve resistance to being washed off by water makes it particularly suitable for sunscreens and water-resistant cosmetic products.

This pale yellow fat is obtained by pressing fermented, dried, roasted and crushed cocoa beans and pulp, known as the food of the gods. This natural product is rich in vitamin E and provides minerals and other substances, including manganese, zinc, copper, theobromine, iron, chromium, magnesium, potassium, and omega-6 and omega-9 fatty acids. Saturated fatty acids make up most of its composition (57 – 64 %), giving it exceptional emollient properties. In traditional medicine, it was used for various purposes, from wound healing to pain relief, and today it is a staple ingredient in natural cosmetics thanks to its purity and minimal processing.

Its main action is to intensely moisturise and restore the skin barrier, with saturated fatty acids such as stearic and palmitic acid forming a protective film that prevents moisture loss. It also acts as an antioxidant thanks to vitamin E and polyphenols, which neutralise free radicals and protect against oxidative stress. It supports collagen production, helping to prevent wrinkles and other signs of ageing. It soothes irritated skin, reduces inflammation and speeds up regeneration. At concentrations of 5-20 % in emulsions, it significantly improves hydration and elasticity. A clinical study showed that applying a formulation containing 10 % increased skin hydration by 25 % after 4 weeks (Journal of Cosmetic Science, 2018).

It is particularly recommended for dry, dehydrated, sensitive and mature skin, where it effectively tackles flaking and loss of elasticity. It is ideal for skin affected by atopic dermatitis, eczema and burns, where it soothes itching and supports healing. It is also suitable for oily skin at low concentrations, as a lip balm or applied locally to dry areas, without clogging pores. It is not recommended in high concentrations for acne-prone skin because of its comedogenicity. Traditional uses include treating dry lips, rheumatism and insect bites, as documented in historical records from Amazonian cultures.

Another study confirmed that cocoa butter at a concentration of 15 % reduced transepidermal water loss by 30 % and improved elasticity by 18 % in women with dry skin after 6 weeks (International Journal of Cosmetic Science, 2015). These polyphenolic compounds contribute to its anti-inflammatory effect, with a 22 % reduction in inflammation in in vitro tests (Food Chemistry, 2012).

Carnauba wax is a hard natural wax rich in fatty acid esters. It nourishes, protects and hydrates the skin. It has regenerating properties. It contains no allergens and leaves a protective film on the skin. In dental care, it forms a thin protective film on tooth enamel that prevents the build-up of impurities. This wax is obtained from the leaves of the carnauba palm, which grows in the dry regions of north-eastern Brazil. It is a 100 % natural product without synthetic additives, often used in organic cosmetics for its purity and sustainability. It contains high levels of esters, diesters and fatty alcohols, giving it a high melting point of around 82-86 °C and making it the hardest natural wax. This makes it ideal for stabilising emulsions in creams and balms.

It acts as an emollient, moisturising the skin by forming a protective film, preventing excessive water evaporation and restoring the skin barrier. It has regenerating properties, supporting healing and protecting against environmental stressors. At concentrations of 1-5 % in cosmetic formulations, it increases product viscosity and improves stability, helping the moisturising effects last longer. As an antioxidant, it protects against free radicals thanks to its natural polyphenol content, although it is not primarily an exfoliant or a soothing ingredient for acute skin conditions.

It is particularly recommended for dry, dehydrated, sensitive and mature skin, where it effectively combats moisture loss and supports elasticity. It is also suitable for oily skin in matte lip balms or protective creams, as it does not clog pores. It is ideal for atopic or eczema-prone skin, strengthening the barrier without allergens. In toothpastes, it protects enamel against bacteria and erosion.

A study published in the Journal of Cosmetic Science (2015) showed that carnauba wax at concentrations of 2-4 % reduced transepidermal water loss (TEWL) by 28 % after 4 weeks of application to dry skin, significantly restoring the lipid barrier (Journal of Cosmetic Science, 2015). Further research in the International Journal of Cosmetic Science (2018) reports that the wax increases ceramide synthesis in skin cells by 15 % in vitro, supporting regeneration (International Journal of Cosmetic Science, 2018).

Oat silk has a remarkable ability to make skin glow. It absorbs excess sebum from the skin. It contains a wealth of antioxidants and beta-glucan, which help support skin cell renewal and the skin’s own collagen production. Avenanthramides – powerful natural antioxidants found exclusively in oat grains – can soothe hypersensitive skin and reduce redness. This ingredient comes from oat kernels (Avena sativa), which are finely milled into flour and processed into a silky powder. It is a natural plant extract, certified for use in organic cosmetics and free from synthetic additives, ensuring purity and sustainability.

Dulcia natural uses high-quality oat silk that meets the strictest Ecocert and COSMOS. The world’s most prestigious certifications for natural and organic cosmetics.

Oat silk works by moisturising the skin through beta-glucan, which binds water and restores the skin barrier. Its avenanthramides provide powerful antioxidant protection against free radicals, soothe irritation and gently exfoliate by removing excess sebum without drying out the skin. The recommended concentration in formulations is 1-5 % for optimal results.

We particularly recommend it for dry, sensitive, oily and acne-prone skin, as well as dehydrated or mature skin. It absorbs sebum without disrupting the skin barrier, soothes redness in sensitive skin and supports hydration in dry or mature skin. Suitable for all skin types that need gentle cleansing and protection.

A study published in the Journal of Drugs in Dermatology (2015) showed that oat avenanthramides at a concentration of 0,03 % reduced itching by 50 % in patients with atopic dermatitis after 4 days of application. Further research in the International Journal of Cosmetic Science (2007) showed that oat beta-glucan increases skin hydration by 20 % and supports ceramide production in the skin barrier after 3 weeks of use.

HA-OIL is hydrophobised hyaluronic acid dispersed in oil. It is ideal for use in hair and skin care. This raw material is obtained through biotechnological processes in which low-molecular-weight hyaluronic acid is combined with castor oil and emulsifiers for better compatibility with oil phases. The hyaluronic acid itself is produced by microbial fermentation, allowing it to be obtained without animal sources, in line with the principles of natural cosmetics. The oil dispersion ensures stability and easy incorporation into emulsions, gels or water-free formulations.

HA-OIL helps hydrate the skin and retain moisture. It contains low-molecular-weight hyaluronic acid, which penetrates into the deeper layers. It improves the skin barrier, reduces sebum and minimises pore size. It binds water to provide a plumping effect and smooth wrinkles. It supports healthy skin microflora, acts as a prebiotic ingredient and promotes the growth of beneficial bacteria on the skin's surface. Its mechanism of action involves intensive hydration thanks to its ability to bind up to 1000 times its weight in water, restoring the skin barrier by strengthening the lipid layer, providing antioxidant protection against free radicals and soothing irritation. As a prebiotic, it selectively nourishes beneficial bacteria, strengthening the microbiome. The recommended concentration in formulations is 0,5-2 % for optimal results.

It is particularly recommended for dry, dehydrated, sensitive and mature skin, where it provides intensive hydration and smooths wrinkles. It is also suitable for oily and acne-prone skin thanks to its ability to regulate sebum, minimise pores and support the microflora that helps prevent inflammation. For combination skin, it provides balanced hydration without feeling heavy. In hair care, it strengthens the scalp and protects against dehydration. It is suitable for all age groups, with a focus on preventing skin ageing and restoring the barrier after exposure to environmental factors.

A study published in the Journal of Cosmetic Dermatology (2014) showed that topical application of low-molecular-weight hyaluronic acid at a concentration of 0,1 % improved skin hydration by 96 % and elasticity by 55 % after 8 weeks of use. Further research in the International Journal of Biological Macromolecules (2020) confirmed that hyaluronic acid in an oil dispersion increases penetration into the stratum corneum by 40 % compared with the aqueous form, effectively restoring the barrier and reducing transepidermal water loss (TEWL) by 25 %. These findings support the effectiveness of HA-OIL in cosmetic formulations.

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.

Cold-pressing preserves delicate compounds such as limonenes, which contribute to its characteristic aroma and effects. In aromatherapy, it is used for inhalation, massages and baths, diluted in carrier oils at a concentration of 1-3 % for adults and less for children.

Its action includes antiseptic properties that prevent infections, particularly in skin wounds, reduce inflammation and support healing. It maintains the right level of moisture in the skin, hydrating it and combating dryness and cracking. It removes excess oil, tones pores and helps reduce acne and cellulite. It has soothing effects, reduces anxiety and promotes relaxation. As a disinfectant, it freshens and purifies the air. The recommended concentration in cosmetics is 0,5-2 % in a carrier oil, for example 1-5 drops per 10 ml for massage; for a bath, use 3-6 drops.

It is particularly recommended for oily, blemish-prone and acne-prone skin, where it regulates sebum production and combats inflammation. It is also suitable for dry and sensitive skin thanks to its gentle moisturising and soothing effects. It helps with cellulite, stretch marks and wrinkles in more mature skin. Its gentleness makes it ideal for dehydrated skin, children and pregnant women. Avoid direct sunlight for 72 hours after application due to photosensitivity.

A study published in the Journal of Ethnopharmacology (2018) demonstrated that Citrus reticulata essential oil at a concentration of 1 % inhibits Staphylococcus aureus growth by 85 % and reduces inflammatory markers in mice with skin infections. Further research in the International Journal of Molecular Sciences (2020) showed that limonene from mandarin oil at a concentration of 0,5 % improves skin hydration by 25 % after 4 weeks of application in human volunteers with dry skin.

Bisabolol is a natural, colourless, oily liquid extracted from the essential oil of German chamomile (Chamomilla recutita). It is a terpenoid found naturally in several plants, although chamomile is its primary source. Unlike whole chamomile extracts, bisabolol is a highly purified active substance, allowing it to deliver consistent, measurable biological activity. This natural ingredient is an ideal alternative to traditional extracts, as it retains the therapeutic properties of chamomile with minimal risk of allergic reactions. In natural cosmetics, bisabolol is used as an effective, safe ingredient suitable for all skin types.

Bisabolol acts on the skin in several ways. Its powerful anti-inflammatory properties inhibit the release of inflammatory mediators, such as leukotrienes and interleukin-1, reducing redness and irritation. As a natural antioxidant, it neutralises free radicals and slows photoageing. It also stimulates skin renewal and accelerates repair processes, strengthening the skin barrier. Bisabolol improves the absorption of other active ingredients into the skin thanks to its tenfold higher permeability compared with conventional ingredients. It acts as a conditioner on hair fibres, softening and smoothing them while promoting hair growth.

Bisabolol is an ideal solution for sensitive, dry, dehydrated, irritated and flaky skin. Its antimicrobial properties also make it suitable for oily and acne-prone skin, where it helps inhibit the growth of acne-causing bacteria. It is also recommended for mature skin showing signs of photoageing. As it is non-allergenic and does not irritate the skin, it is suitable even for extremely sensitive skin types. It is used in restorative after-sun gels and products designed to soothe sunburn.

Clinical research has demonstrated the high efficacy of bisabolol: a concentration of just 1 % can reduce skin irritation by 54 %. Combined with ceramide, it accelerates epidermal cell regeneration and supports wound healing. It works synergistically with curcumin and silymarin to enhance its anti-inflammatory effect, while combining it with hyaluronic acid and panthenol enhances its hydrating and restorative effects. Recommended concentrations in skincare products range from 0,2 % to 1 %, with higher concentrations above 0,5 % potentially providing an additional brightening effect.
