    Publication number: 20060160717
    Abstract: A process for producing powder, flakes, or pellets containing ?-sulfo fatty acid alkylester salt in high concentrations, the process including: (1) a step of preparing a paste containing ?-sulfo fatty acid alkylester salt by a series of reactions of sulfonating a fatty acid alkylester with a sulfonating gas by contact with each other, esterifying the sulfonated product with a lower alcohol, neutralizing the esterified product, and bleaching the neutralized product, to give a paste containing ?-sulfo fatty acid alkylester salt; (2) a step of aging the thus obtained paste; (3) a step of making the aged paste into flakes or pellets containing equal to or less than 10 wt % of water, or a step of making the aged paste into flakes or pellets containing equal to or less than 10 wt % of water and then crushing the resulting flakes or pellets into a powder having an average particle diameter of 100-1500 ?m; and (4) a step of aging the powder, flakes, or pellets.
