SOLID FATTY ACID ALKYL ESTER SULFONATE METAL SALT MATERIAL, AND PROCESS FOR PRODUCTION OF FATTY ACID ALKYL ESTER SULFONATE METAL SALT POWDER HAVING SHARP GRAIN SIZE DISTRIBUTION

摘要

(1) a fatty acid alkyl ester sulfonate metal salt as a solid, a differential scanning calorimetry analyzer the heat absorption peaks at 50 to 130 & 0 & C is an area of 0 to 130 & 0 & C around the absorption peak of the fatty acid is not less than 50% of the area of alkyl ester sulfonate salt solids in the measurement using. (2) the (1) fatty acid, the temperature inside the mill the alkyl ester sulfonate salt solids, characterized in that the grinding at a temperature of less than 30 & 0 & C 50 & 0 & C, fatty acid production method of the alkyl ester sulfonate metal salt powder.
