Abstract:
An anionic surfactant powder prepared by subjecting a mixture of an anionic surfactant and a solvent to microwave irradiation to remove at least a part of the solvent, and a process for preparing the anionic surfactant. The anionic surfactant powder can be suitably used for laundry detergents, detergents for tableware and kitchenware, foaming agents for toothpastes, powdery shampoos, emulsifying agents for polymerization, foaming agents for cement plaster and the like.
