PROBLEM TO BE SOLVED: To provide a production method, capable of providing a stable and homogenous surfactant mixture even when an anionic surfactant is blended in large quantity.SOLUTION: A method for producing a mobile surfactant mixture includes: mixing a raw material including (A) a non-ionic surfactant, (B) an acid type precursor of an anionic surfactant having sulfonic group or sulfuric group, which is prepared by reacting anhydrous sulfuric acid, and (C) a neutralizer for (B), thereby obtaining a mixture including a neutralized material of (B); obtaining from the mixture a suspended mixture with a water content of 15 mass% or less; and separating from the suspended mixture a continuous phase including (A) and the neutralized material of (B), and the other phase. |
