Document Type and Number:

WIPO Patent Application WO/2008/047927

Kind Code:

A1

Abstract:

Disclosed is a method for producing an anionic surfactant, which comprises a step for removing impurities through distillation by introducing a carrier gas into a crude anionic surfactant having a moisture content of 0.01-5% by weight within a granulator with mixing blade or a drier. Also disclosed is a method for producing an anionic surfactant granule, wherein an anionic surfactant granule is obtained while introducing a gas along the wall surface of a granulator with mixing blade or a drier at a reduced pressure.
