Polyethylene glycol cetyl ether

Polyethylene glycol cetyl ether (CAS 9004-95-9), commercially known as Cetomacrogol 1000 and Cetocire, is a nonionic ethoxylated fatty alcohol used across pharmaceutical, cosmetic, and industrial formulations. It functions primarily as an emulsifier, solubilizer, and rheology modifier in both aqueous and semi-solid systems. In pharmaceutical manufacturing, it is a recognized excipient for preparing stable oil-in-water creams.

This versatile chemical is essential for ointment bases and topical drug delivery systems. Personal care formulators rely on it to stabilize emulsions in lotions, moisturizers, and hair conditioning products. In these cosmetic applications, it also contributes significantly to texture and spreadability. In textile and leather processing, it acts as a dispersing and wetting agent that improves dye uptake and surface treatment.

Paper industry applications include its use as a coating additive and processing aid to control viscosity and improve surface finish. It is supplied as a waxy solid or flakes at ambient temperature. Liquid forms are available at elevated temperatures for specific industrial needs. Pharmaceutical-grade material is available to BP and Ph. Eur. specifications, including the defined monograph.

Technical-grade supply is standard for textile and industrial applications. This ensures that the product meets the specific purity and performance requirements for various manufacturing sectors worldwide.
