Polyethylene glycol cetyl ether

Polyethylene Glycol Cetyl Ether (CAS 9004-95-9, EC 500-014-1) is a nonionic surfactant produced by ethoxylation of cetyl alcohol, commercially available under designations including BC7, BC10, BC20, CA16, and OS30. The numerical suffix indicates the degree of ethoxylation, which directly determines HLB value and performance profile. It carries no E-code classification.

In cosmetic and pharmaceutical emulsions, it stabilises oil-in-water systems by reducing interfacial tension between immiscible phases, with higher-ethoxylate grades providing stronger hydrophilic character for lighter formulations. In textile processing, it functions as a fibre lubricant and dispersing agent, keeping hydrophobic finishes uniformly distributed in aqueous baths.

This material is supplied as off-white pellets across multiple ethoxylation grades to suit specific HLB requirements. It falls under REACH regulation and is handled by registered EU importers. Buyers should confirm grade-specific compliance documentation, including REACH registration status and safety data sheets, prior to procurement.
