Abstract:
A solid fatty acid alkyl ester sulfonate metal salt is disclosed having an endothermic peak area between 50° C. and 130° C. of 50% or more relative to the whole endothermic peak area between 0° C. and 130° C. when determined using a differential scanning calorimter. A method for producing a fatty acid alkyl ester sulfonate metal salt powder is also disclosed, including a step of pulverizing the solid fatty acid alkyl ester sulfonate metal salt in a pulverizer, with the internal temperature of the pulverizer being adjusted to 30° C. to 50° C.
