Cetearyl Alcohol (Cetostearyl Alcohol)

Cetearyl Alcohol is a fatty alcohol blend—typically composed of cetyl and stearyl alcohol—widely used in cosmetic formulations as a structuring agent, emollient, and co-emulsifier. It helps build viscosity and creaminess, stabilizes emulsions by reinforcing the internal structure, and improves spreadability and slip for a smoother, more cushioned skin feel. In hair care, it is valued for enhancing softness, reducing the perception of roughness, and supporting manageability by contributing to a conditioning, detangling texture. Cetearyl Alcohol is commonly found in creams, lotions, body butters, cleansers, conditioners, masks, and styling products, where it boosts stability, improves payoff, and creates a richer, more elegant sensorial profile. Use level is formulation-dependent and is typically optimized with the primary emulsifier system and other lipids to achieve the desired thickness, glide, and overall product performance.
