Ingredient
POLYGLYCERYL-2 TRIISOSTEARATE
Substance information
This ingredient contains polymerised glycerin (as alcoholic component). The number behind "polyglyceryl-" refers to the average number of glycerin units. Isostearates are salts or esters of the isostearic acid (isooctadecanoic acid).

Background information on use in cosmetics
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.
