About
A cholesterol-ester emollient — biomimetic to skin's own lipid matrix. Excellent feel and barrier-support profile.
Dihydrocholesteryl Octyldecanoate is the ester of dihydrocholesterol (the saturated form of cholesterol) with 2-octyldecanoic acid, a branched fatty acid. Cholesterol itself is a major lipid of the stratum-corneum intercellular matrix, so cholesterol esters of this type are biomimetic emollients that reinforce barrier feel and improve spread and cushion in creams and color cosmetics. CIR has reviewed cholesterol and several cholesteryl esters with favorable safety outcomes, supporting low topical toxicity, non-sensitizing profile, and strong tolerance on sensitive skin. Commercial grades are usually derived from lanolin or synthetic cholesterol; rare allergic reactions in individuals sensitized to lanolin-derived sterols are possible but uncommon. No endocrine, carcinogenic or reproductive flags.
