Cationic surfactant and method for producing the same |
| abstract |
(57) [Problem] To provide a method for efficiently producing a cationic surfactant having a good color tone. SOLUTION: This is a method for producing a cationic surfactant, which comprises subjecting an alkanolamine ester to a quaternization reaction without a solvent in the presence of 10 to 50 ppm of a phosphoric acid compound with respect to the alkanolamine ester. An embodiment in which the phosphate compound is represented by the following formula (1), wherein the alkanolamine ester is at least an alkanolamine and at least one of a fatty acid and a fatty acid methyl Are preferred. Embedded image However, in the formula (1), R 7 is an alkyl group having 1 to 2 carbon atoms. |
