PURPOSE: To improve fluidity, hygroscopic caking properties, caking properties under pressure of a granulated detergent without lowering its detergency, by depositing calcium carbonate on the whole surface of the granulated detergent comprising an anionic surfactant and an inorganic bilder.
CONSTITUTION: 0.5W5 wt.% based on a granulated detergent of calcium carbonate having an average particle diameter of 2W5μ is deposited on the whole surface of the granulated detergent comprising 10W40 wt.% of an anionic surfactant and 10W80 wt.% of an inorganic bilder. An alkylbenzenesulfonate having an 8W15C alkyl group, an alkyl sulfate having an 8W18C alkyl group, etc. may be cited as the anionic surfactant; a silicic acid, pyrophosphoric acid, etc., as the inorganic bilder. Since not more than 15 wt.% of the phosphoric acid-type bilder is preferably used, 5W20 wt.% of an alkaline metal salt of the silicic acid is preferably contained as one ingredient in the organic bilder.
