Document Type and Number:
Japanese Patent JP3984406
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a method for producing a surfactant composition comprising a quaternary ammonium salt through such a process as to be low in the melt viscosity of the reaction system in a cationization step. SOLUTION: This method for producing a surfactant composition comprising a quaternary ammonium salt comprises reaction between a fatty acid or an ester thereof and an alkanolamine followed by quaternization (cationization) of the resultant intermediate amine with a dialkyl sulfate salt; wherein it is characterized that as quaternization auxiliary, a terminal-etherified polyoxyethylene fatty acid ester represented by the formula: R7COO(CH2CH2 O)nR8 is added to the reaction system.
