To profitably obtain the subject compound free from turbidity, precipitates, etc., good in smell and useful for cosmetics, perfumeries such as shampoos, etc., by reacting a specific fatty acid halide with a specified multi- hydrophilic group type amino (salt), etc.
This method for producing a multi-hydrophilic group type N-long chain acylcarboxylic acid or its salt comprises reacting a phosphorus trihalide with a fatty acid, distilling the reaction product, reacting (A) the obtained compound of the formula: R1COX [R1 is a 5-21C (branched) alkyl, an alkenyl, a hydroxyalkyl; X is a halogen] with (B) a compound of formula I [R2 is a 1-3C (branched) alkylene; Y is a group of the formula: COOM (M is H, a cation), a group of the formula: OSO3M, a group of the formula: OPO(OM)2, a group of the formula: GSO3M, a group of the formula: OM; (m) is 1-3] and, if necessary, subsequently exchanging the salt to obtain the compound of formula III, or reacting the component A with (C) a compound of formula II, hydrolyzing the obtained product and, if necessary, exchanging the salt to obtain the compound of formula III.
