The present invention relates to a solid laundry detergent composition in particulate form comprising a plurality of particulate components, the composition comprises: (i) alkyl benzene sulphonate anionic detersive surfactant; (ii) carboxylate polymer; (iii) carbonate salt; (iv) from 0% to less than 5%, by weight of the composition, of zeolite builder; (v) from 0% to less than 5%, by weight of the composition, of phosphate builder; and (vi) optionally, from 0% to less than 5%, by weight of the composition, of silicate salt; wherein: (a) any particulate component that comprises at least 5%, by weight of the particulate component, of alkyl benzene sulphonate anionic detersive surfactant also comprises carbonate salt, wherein the weight ratio of the carbonate salt to the alkyl benzene sulphonate anionic detersive surfactant present in the particulate component is greater than 1: 1 ; (b) any particulate component that comprises at least 5%, by weight of the particulate component, of alkyl benzene sulphonate anionic detersive surfactant also comprises carboxylate polymer, wherein the weight ratio of the alkyl benzene sulphonate anionic detersive surfactant to the carboxylate polymer present in the particulate component is in the range of from 0.2: 1 to 5: 1 and (c) any particulate component that comprises at least 5%, by weight of the particulate component, of alkyl benzene sulphonate anionic detersive surfactant also comprises from 0% to 10%, by weight of the particulate component, of silicate salt; and (d) the weight ratio of carbonate salt to carboxylate polymer present in the composition is in the range of from 1 : 1 to 30: 1.
L'invention porte sur un détergent en particules solides comportant les composants particulaires suivants: (i) un tensio-actif détergent de sulfonate anionique d'alkyle benzène; (ii) un polymère de carboxylate; (iii) un carbonate; (iv) de 0 % à moins de 5 % en poids de la composition d'un adjuvant de zéolite; (v) de 0 % à moins de 5 % en poids d'un adjuvant de phosphate; (vi) facultativement de 0 % à moins de 5 % en poids de la composition de silicate. De plus: (a) toute particule comprenant au moins 5 % en poids de sulfonate anionique d'alkyle benzène comprend également un carbonate, le rapport pondéral carbonate/sulfonate étant supérieur à 1: 1; (b) toute particule comprenant au moins 5 % en poids de sulfonate anionique d'alkyle benzène comprend également un polymère de carboxylate, le rapport pondéral sulfonate/polymère de carboxylate étant compris entre 0.2: 1 et 5: 1; (c) toute particule comprenant au moins 5 % en poids de sulfonate anionique d'alkyle benzène comprend également de 0 % à 10 % en poids de silicate; et (d) le rapport pondéral carbonate/polymère de carboxylate de la composition est compris entre 1: 1 à 30: 1.
