About

A cholesterol-derived emollient that conditions and smooths the skin.

Cholesteryl butyrate is the ester of cholesterol and butyric acid, functioning as a skin conditioning agent and emollient in cosmetic formulations. It is listed in EU CosIng and is not subject to specific restriction. Research suggests it may support barrier function and exhibit anti-inflammatory properties, though it is primarily used for its elegant, velvety skin feel. High molecular weight limits systemic absorption.
