摘要： The method of making a granulate composition for decolorizing or bleaching hair consists of preparing a powdery mixture consisting of from 30 to 65% by weight of one or more inorganic persulfates, from 1 to 20% by weight of a binding agent selected from the group consisting of polyvinylpyrrolidone and polyethylene glycols having molecular weights of 200 to 10,000; of 15 to 45% by weight of at least one salt selected from the group consisting of alkali metal carbonates, alkaline earth metal carbonates, alkali metal hydrogen carbonates, alkali metal silicates and from 0.1 to 3 percent by weight of a chelating agent, and one or more auxiliary and additive substance selected from the group consisting of perfume oils, hair dyes, amphoteric, anionic, cationic and nonionic surface-active substances and water-soluble thickeners; after making this powdery mixture, spraying ethanol and/or isopropanol in a weight ratio from 13:1 to 4:1 (powdery mixture to alcohol) into the powdery mixture to form a moistened mixture; granulating the moistened mixture formed during the spraying in a granulating apparatus to form a moist granulate; and after the granulating, drying the moist granulate to remove the alcohol or alcohols and to form the granulate composition.
