About this ingredient

Octadecene is a long-chain olefin (C18 alkene) used as an emollient and skin conditioning agent in cosmetic formulations. It provides lubricity and helps soften the skin while improving the spreadability of products. Its hydrocarbon structure makes it an effective occlusive agent that can enhance skin barrier function.
