Expert Verdict
Generally considered mild compared to sulfate surfactants; 1,4-dioxane residual concern due to ethoxylation process; potential skin irritation at high concentrations.. IUPAC: Poly(oxy-1,2-ethanediyl), ฮฑ-carboxymethyl-ฯ-dodecyloxy (3 mol EO average); the terminal carboxyl group imparts anionic character; pH-dependent behavior - more soluble at higher pH; used as a mild secondary surfactant.
