Cetyl lactate

Cetyl lactate (CAS 35274-05-6), also known by its FEMA 4483 designation, is an ester of cetyl alcohol and lactic acid used as an emollient and skin-conditioning agent in personal care and pharmaceutical formulations.

It functions as a lightweight carrier, softener, and emulsification aid, contributing to texture refinement and moisture retention in finished products. In cosmetic formulations, it is used in creams, lotions, and body butters.

This ingredient delivers a smooth, non-greasy skin feel while supporting emulsion stability. It acts as a plasticizer in film-forming systems, improving flexibility and spreadability in leave-on skin and hair care products.

Pharmaceutical topical preparations use it as a carrier and emollient base in ointments and dermal delivery systems where skin compatibility and texture are formulation priorities. It also functions as a solvent and dispersant.

This material is highly effective for active ingredients in color cosmetics and sunscreen formulations. It is typically supplied as a waxy solid or flake at ambient temperature, becoming a clear to pale yellow liquid when melted.

It is available in cosmetic-grade and pharmaceutical-grade specifications to meet purity requirements across regulated markets. Bulk supply is standard in fiber drums or bags, with smaller packaging available for laboratory use.
