PROCESS FOR MAKING ALKYL ETHOXY CARBOXYLATES An improved process for the production of alkyl ethoxy carboxylate surfactants comprising reacting ethoxylated fatty alcohols with a selective hindered base and anhydrous chloroacetic acid or a salt thereof. The reactants can be reacted simultaneously or, initially, the hindered base can be reacted with the ethoxylated fatty alcohol and, subsequently the resultant product reacted with anhydrous chloroactetic acid or a salt thereof.
