Cetyl stearate

Cetyl stearate (CAS 1190-63-2 ) is a synthetic wax ester produced from cetyl alcohol and stearic acid, used across cosmetic and pharmaceutical manufacturing as an emollient and texture modifier.

It belongs to the broader family of wax esters that give solid and semi-solid formulations their structural integrity and skin-feel characteristics. In skin care, it contributes a smooth, non-greasy feel.

This ingredient improves spreadability and emulsion stability in creams, lotions, and balms. Lip care products rely on it to adjust hardness and provide a waxy, protective film on application.

In pharmaceutical topical preparations, it functions as a consistency agent in ointments and suppository bases. This helps control the melting point and overall product texture during application.

Color cosmetics manufacturers use it to adjust the rheology of pressed and stick formats. This improves payoff and structural cohesion, ensuring the product maintains its shape and performance.

The material is supplied as a white to off-white solid, typically in flake or pastille form for ease of handling. It is available in cosmetic-grade and pharmaceutical-grade specifications.

The pharmaceutical-grade material often meets USP or Ph.Eur. purity standards. Bulk supply is standard for industrial formulators, with smaller quantities available for development.
