Ingredient
ISOSTEARIC/MYRISTIC GLYCERIDES
Substance information
The name component "isostearic" means that the ingredient contains, as fatty acid component, amongst others, isostearic acid (mostly introduced via an acylation reaction). The name component "myristic" means that the ingredient contains, as fatty acid component, amongst others, myristic acid (tetradecanoic acid) (mostly introduced via an acylation reaction). Glycerides are conversion products of glycerin (esters), which are obtained through a reaction with fats (through so-called trans-esterification) or through direct esterification with one or more fatty acid(s) (mono-, di- or triglycerides).

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.
