HAND WASH LAUNDRY DETERGENT COMPOSITIONS CONTAINING A COMBINATION OF SURFACTANTS AND SOIL RELEASE POLYMER

摘要

The subject invention involves laundry detergent compositions, preferably in granular form, particularly useful for machine laundry operations. The compositions comprise: a) from about 6 % to about 18 % surfactant comprising 1) from about 5 % to about 10 % anionic surfactant selected from alkylbenzene sulfonate surfactant, alkyl sulfate surfactant and alkyl ethoxy ether sulfate surfactant; 2) from about 0.2 % to about 4 % hydroxyalkyl quaternary ammonium cationic surfactant; and 3) from 0.4 % to about 8 % nonionic surfactant selected from alkyl ethoxy alcohol surfactant, amine oxide surfactant, and polyhydroxy fatty acid amide surfactant; b) from about 0.05 to about 4 % polymeric soil release agent comprising: 1) from about 10 % to about 99.5 % esters comprising, per mole of said ester: i) from about 1 to about 2 moles of sulfonated polyethoxy/propoxy end-capping units; ii) from about 0.5 to about 66 moles of units selected from the group consisting of a) oxyethyleneoxy units; b) a mixture of oxyethyleneoxy and oxy-1,2-propyleneoxy units; and c) a mixture of a) or b) with poly(oxyethylene)oxy units; iii) from about 1.5 to about 40 moles of terephthaloyl units; and iv) from 0 to about 26 moles of 5-sulfoisophthaloyl units; 2) from about 0.5 % to about 20 % crystallization-reducing stabilizer selected from sulfonate-type hydrotrope, alkylbenzene sulfonate, paraffin sulfonate, and mixtures thereof; and c) from about 80 % to about 94 % other components.
