Abstract: Disclosed is the method for producing an anionic surfactant powder, including removing impurities by introducing gas into a crude anionic surfactant containing water in a content of 0.01 to 5% by weight in a granulator or drier, having an agitating blade. Also disclosed is the method for producing an anionic surfactant powder, including introducing a gas along with the surface of an inner wall of a granulator or drier having an agitating blade at a reduced pressure to produce the anionic surfactant powder.
