A SOLID LAUNDRY DETERGENT COMPOSITION COMPRISING ALKYL BENZENE SULPHONATE, CARBONATE SALT AND CARBOXYLATE POLYMER

摘要

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.
