Cetearyl alcohol

Cetearyl alcohol (CAS 67762-27-0), also known as cetylstearyl alcohol or Alcohols C16-18, is a fatty alcohol blend used as an emulsifier and consistency agent across personal care, pharmaceutical, and food manufacturing. It stabilizes oil-in-water and water-in-oil systems while contributing body and texture to finished formulations. In cosmetic manufacturing, it functions as the structural backbone of creams and lotions.

This material provides the thick, spreadable consistency consumers expect from moisturizers and hair conditioners. Pharmaceutical topical formulations rely on it to stabilize emulsion bases in ointments and creams. Consistent viscosity directly affects dosage uniformity in medical applications. In hair care, it coats and detangles fiber, making it a standard inclusion in rinse-off conditioners and leave-in treatments.

Food-grade material is used as an emulsifier and surface-finishing agent in select processed food applications. Cetearyl alcohol is supplied as white waxy flakes or pellets for ease of handling. These forms are preferred for metering in heated mixing processes. Standard grades include cosmetic/personal care, USP, BP, and Ph.Eur., supporting both regulated pharmaceutical and general industrial procurement.

Technical-grade material is available for non-cosmetic industrial applications where pharmacopoeial certification is not required. This versatile ingredient remains a staple for formulators seeking stability and texture.
