About
A polyethylene glycol ether of cetearyl alcohol used as an emulsifier in cosmetic emulsions, providing stable and pleasant textures.
Ceteareth-4 is the polyethylene glycol ether of cetearyl alcohol (a blend of cetyl and stearyl alcohols) with an average of 4 moles EO. It functions as an emulsifier and surfactant in cosmetic formulations, helping to create stable oil-in-water emulsions. It is listed in EU CosIng without specific restriction. The C16-18 alcohol chain with low EO provides good emulsification performance while maintaining skin compatibility typical of fatty alcohol ethoxylates.
