Description
Cetyl laurate (CAS 20834-06-4, EC 244-071-8), also known as palmityl laurate or hexadecyl laurate, is a fatty acid ester formed by the esterification of lauric acid with cetyl alcohol. It carries no assigned E-code and is classified within the oils, fats, and waxes category.
In personal care formulations, cetyl laurate functions as an emollient and emulsifier, reducing interfacial tension between oil and water phases to stabilise creams and lotions while depositing a conditioning film on skin. In pharmaceutical topical preparations, it serves as a plasticiser and carrier, improving spreadability and facilitating active ingredient delivery across the skin barrier.
Cetyl laurate is supplied for use in cosmetic and pharmaceutical applications and falls under REACH registration requirements for EU market access. Procurement teams should confirm supplier documentation includes safety data sheets and certificates of analysis aligned with relevant cosmetic or pharmaceutical grade specifications.
