Abstract:
A process for the preparation of a salt of fatty acid ester of hydroxycarboxylic acid, which comprises subjecting a fatty acid ester of lower alcohol and an alkaline metal salt or alkaline earth metal salt of hydroxycarboxylic acid to ester interchange in an organic solvent in the presence of a nonionic or anionic surface active agent and an alkali catalyst.
