Abstract (en)
[origin: WO9213937A1] The granular additive disclosed, which may be used to pretreat hard water or employed together with washing and cleaning agents, contains 40-75 % by wt. of the sodium salts of at least one homopolymer or copolymer of methacrylic acid, 1-35 % by wt. of a finely crystalline synthetic zeolite containing bound water, 2-20 % by wt. of sodium sulphate (calculated as the anhydrous salt) and 1-15 % by wt. of water. The granulate initially produced preferably by spray drying is compacted under the action of pressure to give a granulate with a bulk density between 500 and 900 g/l, without affecting the free-running or storage characteristics of the granulate.
