Abstract:
Disclosed is a method for producing an anionic surfactant powder, which comprises a step wherein an aqueous anionic surfactant solution having an anionic surfactant concentration of 0.01-40% by weight is introduced into a granulating machine or a drying machine having a mixing blade under a reduced pressure for granulation and drying.
