APRICOT KERNEL OIL POLYGLYCERYL-5 ESTERS

Substance information

Ingredient on the basis of apricot kernel oil (prunus armeniaca kernel oil). This ingredient contains polymerised glycerin (as alcoholic component). The number behind "polyglyceryl-" refers to the average number of glycerin units. "Ester" or "esters" refers to an esterification product (condensation product of alcohol and acid) or a trans-esterification product obtained through direct reaction of fats (mostly triglycerides) with alcohols.

Background information on use in cosmetics

Apricot kernel oil is a high-quality vegetable oil which is obtained by cold pressing from the inner, soft part of the apricot kernel. With 35 % the kernel has a very high share in the valuable vegetable oil. Apricot kernel oil (INCI: PRUNUS ARMENIACA KERNEL OIL) is rich in essential fatty acids and Vitamin E. Apart from linoleic acid and palmitic acid, oleic acid constitutes the largest component of the apricot kernel oil. Unsaturated fatty acids such as oleic acid are very important for the human body since it cannot produce those itself. Although apricot kernel oil is suited for all skin types, it is recommended, more particularly, for dry skin since it can support the skin in storing moisture. In haircare, apricot kernel oil can straighten the hair and hence improve the hair gloss. It is used in shampoos, rinses and cures. Vegetable oils are characterised by a high share of (poly) unsaturated fatty acids, which are characteristic for the liquid consistency. As an admixture many vitamins, carotenoids and free fatty acids are present. Surfactants are so-called detergent substances and have a major significance in cosmetics for the cleansing of the skin and hair. Surfactants are substances which, based on their molecular structure, are able to reduce the surface tension of a liquid. In this way it is possible that two actually not mixable substances, such as oil and water, can be finely mixed. Because of their properties, surfactants have manifold uses in cosmetics: they can cleanse, produce foam and act as emulsifiers and mix substances with one another. In shampoos, shower gels and soaps, surfactants are, for instance, used to wash fat and soil particles with water off from the body. Surfactants are also used in toothpaste. Here they promote during tooth cleaning the rapid and full dissolution and distribution of the paste in the mouth. The surfactants used in cosmetic products are primarily produced synthetically on the basis of vegetable raw materials. Surfactants are often used in combination to equally meet all desired requirements – like dissolution of soil and formation of foam in combination with a good skin tolerance – in the best possible manner. Through a skilled combination of a surfactant – viewed on its own – with unfavourable skin tolerance but a very good soil removal property with a very mild, skin protecting surfactant altogether a product with good cleansing properties and the same good skin tolerances is obtained. Emulsifiers are often used in cosmetics as excipients. They allow actually unmixable components like oil and water to be brought in a permanently stable emulsion. In this way both aqueous and oily care and active ingredients can be used in one and the same product in cosmetics. Emulsifiers are able to do that since their molecules consist of a lipophilic and a hydrophilic part. In this way they can reduce the interfacial tension which actually exists between two incompatible substances like fat and water. Emulsifiers are, more particularly, used for creams, lotions and cleansing agents. At present emulsifiers are, however, more than only excipients which keep an emulsion stable. Fatty acid esters on the basis of sugar, lecithin or glycerin monodistearate contribute, for instance, to improving the moisture balance of the skin and are, therefore, also considered as cosmetic active ingredients.
