1. A detergent composition containing in combination(a) 0.5 to 80% by weight of a detergent builder system containing a carboxylate or polycarboxylate builder containing from one to four carboxy groups, wherein said detergent builder system has a major proportion by weight of non-carbonate builder compound and is free of phosphate-containing builder;
- (b) 0.1 to 10% by weight of a non-nitrogen containing organo diphosphonic acid or its salts or complexes or any mixture thereof;
(c) 0.1 to 10% by weight of an organic polymer containing acrylic acid or a salt thereof, having an average molecular weight of less than 15,000, and being selected from the group consisting of (I) homopolymers of acrylic acid and (ii) copolymers of acrylic acid or a salt thereof and a comonomer selected from the group consisting of (1) substituted acrylic acid of the formula CHR2 ═
CR1 (CO--O--R3) wherein R1 and R2 are individually C1 -C4 alkyl, C1-C4 hydroxyalkyl, or hydrogen, and R3 is C1 -C4 alkyl, C1 -C4 hydroxyalkyl, hydrogen or an alkali metal salt, with at least one of R1, R2 and R3 being C1 -C4 alkyl or C1 -C4 hydroxyalkyl, (2) fumaric acid, maleic acid, itaconic acid, aconitic acid, mesaconic acid, citraconic acid, methylenemalonic acid, or salts of any of said acids, (3) maleic anhydride, (4) acrylamide, (5) alkylene, (6) vinylmethyl ether, (7) styrene, and (8) mixtures thereof, and(d) a silicate, wherein the detergent composition is in solid form.
