To provide a method for producing a soap composition by which the occurrence of aggregation and yellowing is prevented.

The method for producing the soap composition involves solidifying a molten soap containing (A) a fatty acid soap, (B) a monovalent inorganic salt, (C) a polyvalent inorganic salt and (D) polyols regulated so that the total of the components (A) and (D) may be 30-75 wt.%. The fatty acid soap of the component (A) is formed by neutralizing a fatty acid with an alkali in a preparation process of the molten soap. The neutralization is carried out in the presence of one of the components (B) and (C), and the component (D), and the components (B) and (C) are fed to the preparation process of the molten soap as aqueous solutions.
