About

An ester of cholesterol and isostearic acid used as a premium emollient and thickener in cosmetic formulations, providing a smooth non-greasy skin feel with excellent tolerability.

Cholesteryl isostearate is a cholesteryl ester widely used in high-end cosmetic and pharmaceutical topical formulations as an emollient, viscosity-controlling agent, and emulsion stabilizer. It is not subject to EU cosmetic restrictions and has an excellent safety profile, with structural similarity to natural skin lipids making it particularly well-tolerated on sensitive skin.
