UN PROCEDIMIENTO PARA PREPARAR UNA MEZCLA DE SULFATO DE AL- QUILETER Y ACIDO CARBOXILICO DE ETER DE ALQUILPOLIGLICOL O UNA SAL DEL MISMO

摘要

Mixtures of alkylether sulphate and alkylpolyglycol ether carboxylic acid or salt thereof are provided, wherein the alkylpolyglycol ether carboxylic acid contains at least 7 oxyethylene residue, said mixtures containing 80-95% by weight of alkylether sulphate and 20-5% by weight of alkylpolyglycol ether carboxylic acid or salt thereof. In spite of this low percentage of polyether carboxylic acid, these compositions show a highly decreased skin toxicity. Also compositions intended for frequent or prolonged contact with human hair and skin are provided, which contain such mixtures as detergents.
