PROBLEM TO BE SOLVED: To provide a method for producing an N-acyltaurine compound expected to have mild and low-stimulation nature to the skin and hair as a body cleaning compound in high purity and quality at a low cost.
SOLUTION: The method for the production of the N-acyltaurine compound comprises the direct reaction of a taurine salt expressed by general formula (1): R1NHCH2CH2SO3M (R1is H or 1-6C alkyl or cycloalkyl; and M is an alkali metal or an alkaline earth metal) with a fatty acid expressed by general formula (2): R2COOH (R2is an 8-18C straight chain alkyl or unsaturated hydrocarbon group) while introducing nitrogen gas into the system. The nitrogen gas is dried nitrogen gas having a water content of ≤1,000 ppm and the gas is blown through an ejection pipe having a porous glass attached to the blowing opening at a rate of 1/5-2 times mol based on water generated by the reaction.
