Abstract
The present invention relates to detergent compositions comprising an anionic surfactant system. The anionic surfactant system comprises alkyl alkoxylated sulphate having specific ratios of mono-, di- and trialkoxylated sulphate. The anionic surfactant system provides improved oily and greasy soil removal over a wide temperature range.
Claims20
A detergent composition, comprising (a) from 1% to 90% of an anionic surfactant comprising at least 30% of alkyl alkoxylated sulphate having an average degree of alkoxylation of from 0.1 to 3, and a balance of anionic surfactant other than alkyl alkoxylated sulphate, wherein the ratio of the combined weight of alkyl monoalkoxylated sulphate and alkyl dialkoxylated sulphate to the total weight of the anionic surfactant is from 0.2 to 1, and the ratio of the combined weight of the alkyl monoalkoxylated sulphate and the alkyl dialkoxylated sulphate to the total weight of alkyl alkoxylated sulphate having 3 or more alkoxy groups per alkyl group is at least 1, and (b) at least one builder or chelant, or a mixture thereof.
A detergent composition, comprising (a) from 1% to 70%, by weight, of an anionic surfactant comprising at least 50%, by weight, of alkyl alkoxylated sulphate having an average degree of alkoxylation of from 0.1 to 3, and a balance of anionic surfactant other than alkyl alkoxylated sulphate, wherein the ratio of the combined weight of alkyl monoalkoxylated sulphate and alkyl dialkoxylated sulphate to the total weight of the anionic surfactant is from 0.3 to 1, and the ratio of the combined weight of the alkyl monoalkoxylated sulphate and alkyl dialkoxylated sulphate to the total weight of alkyl alkoxylated sulphate having 3 or more alkoxy groups per alkyl group is from 2 to 8, and (b) from 15% to 50%, by weight, of at least one component selected from the group consisting of builders, chelants, and mixtures thereof.
A detergent composition, comprising (a) from 1% to 70%, by weight, of an anionic surfactant comprising at least 50%, by weight, of alkyl alkoxylated sulphate having an average degree of alkoxylation of from 0.1 to 3, and a balance of anionic surfactant other than alkyl alkoxylated sulphate, wherein the ratio of the combined weight of alkyl monoalkoxylated sulphate and alkyl dialkoxylated sulphate to the total weight of the anionic surfactant is from 0.3 to 1, and the ratio of the combined weight of the alkyl monoalkoxylated sulphate and alkyl dialkoxylated sulphate to the total weight of alkyl alkoxylated sulphate having 3 or more alkoxy groups per alkyl group is from 2 to 8, and (b) from 15% to 50%, by weight, of at least one component selected from the group consisting of builders, chelants, and mixtures thereof, wherein the composition is essentially free of linear alkyl benzene sulphonate.
