What it is
Stearyl caprylate is a wax ester formed from a fatty alcohol and a medium-chain fatty acid. It imparts a smooth, light emollient feel and helps condition the skin surface, and it can also contribute to the texture and spreadability of creams and sticks. It is often used alongside related esters to fine-tune the sensory profile of a formula.
Safety & warnings
Esters of this type are generally well tolerated and non-irritating in cosmetic use. As a fatty ester it is occlusive and emollient; individuals prone to clogged pores may wish to note its lipid nature, though it is not a recognized high-comedogenicity oil.
Origin & sourcing
Typically manufactured synthetically by esterification, with the fatty alcohol and fatty acid feedstocks commonly derived from plant oils.
