About

A branched-chain ester emollient that delivers a light, smooth skin feel in creams, lotions, and colour cosmetics.

Isodecyl stearate is the ester of isodecyl alcohol (a branched C10 alcohol) and stearic acid, functioning as an emollient and skin conditioning agent in cosmetic formulations. It is listed in the EU CosIng database without restrictions. The branchedchain structure gives it a lighter feel compared to linear esters, making it popular in light moisturisers and makeup products.
