AQUEOUS SURFACTANT SOLUTION AND METHOD FOR PRODUCING THE SAME

摘要

Disclosed is an aqueous surfactant solution which is characterized by exhibiting fluidity even at room temperature, and containing 30-70% by mass of a mixture of an a-sulfofatty acid alkyl ester salt and an a-sulfofatty acid disalt, and 1-50% by mass of an unsaturated fatty acid having 10-22 carbon atoms relative to the mixture content. This aqueous surfactant solution is further characterized by having a pH of 3-8. Also disclosed is a method for producing such an aqueous surfactant solution.
