Cetyl stearate

Cetyl stearate (CAS 1190-63-2) is a wax ester formed by the esterification of cetyl alcohol and stearic acid, commercially available under trade names including Wickenol 121, Schercemol CS, and Palmityl stearate. It carries no assigned E-code and is classified within the oils, fats, and waxes category.

In cosmetic formulations, cetyl stearate functions as an emollient and consistency agent in creams and lotions, where it reduces transepidermal water loss by forming an occlusive layer on the skin surface. In pharmaceutical topical preparations, it acts as a plasticizer and co-emulsifier, improving the spreadability and structural stability of ointment bases.

Cetyl stearate is supplied in solid form and is subject to REACH registration requirements for EU market entry. Procurement teams should confirm supplier compliance with REACH and, for pharmaceutical applications, request material aligned with relevant pharmacopoeial standards. Packaging formats typically include bags or fibre drums depending on order volume.
