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.
