Abstract
The present invention provides a method of producing an aqueous solution containing an N—Cacyl acidic amino acid and/or a salt thereof and having pH 8.4-9.5, including the first step for reacting an acidic amino acid and/or a salt thereof with a Cfatty acid chloride in a water solvent at pH 10-13 to form an N—Cacyl acidic amino acid salt, and the second step for adjusting the pH of the aqueous solution after the first step to 8.4-9.5.
