About

A PEG-5 ethoxylated oleic acid-derived quaternary ammonium surfactant with typical concerns for this chemical family.

PEG-5 Oleammonium Methosulfate is an oleic acid-derived quaternary ammonium salt with 5 moles of ethylene oxide and methosulfate as the counterion. It functions as a conditioning surfactant. As with all PEGylated quaternary compounds, concerns center on residual ethylene oxide and 1,4-dioxane contamination formed during ethoxylation. The short PEG chain (5 EO) means lower residual EO risk than higher EO variants. No specific EU restriction applies.
