Abstract:
1. A laundry detergent composition comprising: (a) from about 0.1% to about 80%, by weight of the composition, of a polyamine mono-anionic surfactant having the structure formula: where R is selected from hydrogen, linear or branched C 1 -C 4 alkyl, C 7 -C 12 Alkylaryl, C 2 -C 12 alkylene, C 3 -C 12 hydroxyalkylene, C 4 -C 12 dihydroxyalkylene, C 8 -C 12 dialkylarylene, and where μ and ν are in the range of 0 to 4 and the sum of μ and ν are between 1 and 4; R 1 is selected from hydrogen, linear or branched C 1 -C 4 alkyl, C 6 -C 12 alkylaryl, C 2 -C 12 alkylene, C 3 -C 12 hydroxyalkylene, C 4 -C 12 dihydroxyalkylene, C 8 -C 12 dialkylarylene; R2 is selected from R1 and amine oxide; R′ is selected from C the values of α, β, and γ are between 0 to 10 and the sum of α and β is greater than or equal to 1; S − is: R 3 −L 31 where R 3 is selected from straight or branched C 6 -C 22 alkyl, C 6 -C 22 alkylene, C 6 -C 22 polyoxyalkylenalkyl, C 6 -C 22 polyoxyalkylenacyl, C 6 -C 22 alkylaryl, rosin derivatives, C 6 -C 22 N-acylalkyl; C 6 -C 22 α-sulfonatedtoalkyl, C 6 -C 22 hydroxyalkyl, and C 6 -C 22 hydoxyalkylene; where L − is selected from COO − , SO 3 − , OSO3 − , phosphoric acid, phosphorous acid amino acids, aromatic carboxylic acid, sugar base acids derived from oxidation of monosaccharides and polysaccharides; (b) from about 0.05% to about 2%, of a solubilizer selected from the group consisting of anionic, non-ionic, and amphoteric surfactants having an HLB greater than about 10; (c) wherein the weight ratio of anionic conjugated acid of the polyamine mono-anionic surfactant to the solubilizer, WR, is equal to or greater than R, which is defined by the equation 1: where N is greater than or equal to 2 and is the number of amine groups in polyamine.
