Expert Verdict

1,4-dioxane residue risk (ethoxylated backbone). The carboxylate head group makes this an anionic surfactant, generally considered milder than non-carboxylated pareth counterparts. Ether carboxylic acid - combines the mildness profile of nonionic surfactants with the cleansing efficiency of anionics. pH-dependent charge (anionic above ~pH 5). Often used as a primary or secondary surfactant in mild cleansing systems
