Cetyl acetate

Cetyl acetate (CAS 629-70-9) is a fatty acid ester derived from cetyl alcohol and acetic acid, supplied as a solid wax. It is also known by the trade designations Acelan A and Palmityl Acetate, and referenced in chemical databases under the codes NSC 8492 and ENT 1025. No E-code designation applies to this substance.

In personal care formulations, cetyl acetate functions as an emollient and emulsifier, integrating into the lipid phase of creams and lotions to improve skin feel and stabilise oil-water systems. In pharmaceutical topical preparations, it acts as a plasticiser and carrier, modifying the texture of ointment bases and supporting controlled delivery of active ingredients into the skin.

Cetyl acetate is available in cosmetic and technical grades and is subject to REACH registration requirements for EU supply. Procurement quantities are typically offered in kilogram bags or fibreboard drums. Buyers should confirm grade suitability against relevant pharmacopoeial or cosmetic regulatory standards prior to formulation use.
