| abstract |
The invention relates to a granular to powdery additive to be used in detergents or washing processes, comprising (A) finely crystalline, synthetic, hydrated zeolite of the NaA type, (B) polymeric polycarboxylates derived from acrylic acid and its copolymers with maleic acid in the form of the sodium salts and (C ) Sodium perborate in the form of the monohydrate and / or tetrahydrate. The weight ratios of A: B are 30: 1 to 4: 1, of A: C = 12: 1 to 2: 1 and of B: C = 2: 1 to 1:10, the proportions of components A and B being anhydrous substances and component C can be calculated as monohydrate. The composition consists of a dry mixture of at least two powder components, of which the 1st component contains the components A and B in the form of a spray-dried granulate and the 2nd powder component contains the sodium perborate. |
