About

An ether of cetyl alcohol and ethylene glycol (2-(hexadecyloxy)ethanol) used as a surfactant and emulsifier, providing good skin compatibility in rinse-off formulations.

Ceteth-1 (CAS 2136-71-2 / 904-95-9), chemically 2-(hexadecyloxy)ethanol, is a C16 Guerbet ether formed from cetyl alcohol and ethylene glycol. It functions as a nonionic surfactant and emulsifier. The C16 chain length and single ethylene oxide unit give it a more lipophilic character. Not listed in EU Annex II or III restrictions, and the Guerbet ether structure is considered chemically stable and safe in cosmetic applications.
