<p>1. A bleaching agent in the form of a granulate of uniform composition which contains an aliphatic C4 -C36 peroxycarboxylic acid solid at room temperature and hydratable inorganic salt, characterized in that it contains 3 to 50% by weight of the peroxycarboxylic acid, 40 to 95% by weight, based on the anhydrous form, of hydratable inorganic salt and 0.2 to 10% by weight of an organic polymer compound soluble in alkaline-aqueous medium as granulation aid, the granulate being free from microcrystalline cellulose where microfine starch is present, all the components are uniformly distributed in the individual grains of the granulate and the granulates alone, 0.5% in water, have a pH value in the range from 3 to 7.</p> |
