Chemistry, Properties & Perfumer Guide

The Chemistry

Poly(oxy-1,2-ethanediyl), α-(isooctylphenyl)-ω-hydroxy- is a synthetic nonionic surfactant polymer. It belongs to the class of alkylphenol ethoxylates, formed through the polymerization of ethylene oxide with isooctylphenol. The material exhibits surfactant properties due to its amphiphilic structure, with a hydrophobic alkylphenyl group and hydrophilic polyoxyethylene chain. Production involves controlled ethoxylation reactions under alkaline conditions.
