Abstract

Bleaching agents in the form of granulates of uniform composition which contain PA1 (a) a solid aliphatic peroxycarboxylic acid, PA1 (b) a hydratable inorganic salt, and PA1 (c) an organic polymer granulation aid soluble in alkaline aqueous medium, wherein the granulate, when dissolved in water, has a mildly acidic pH.
