Abstract

A liquid laundry detergent composition that includes: a liquid phase; a solid cleaning active, where the active is selected from the group of soil-release polymer, brightener, polycarboxylate polymer or mixtures thereof, and where the solid is dispersed within the liquid phase.

First claim

What is claimed is:

1 . A liquid laundry detergent composition comprising:
a. a liquid phase; b. between about 0.5% and about 7.5% by weight of the liquid detergent composition of a solid cleaning active, wherein said active is selected from the group of soil-release polymer, brightener, polycarboxylate polymer or mixtures thereof, wherein the solid is dispersed within the liquid phase, and wherein the water-soluble solid phase is defined as the solid obtained when the liquid laundry detergent composition is centrifuged at about 1200 G for about 10 mins; and wherein the liquid phase comprises between about 5% and about 40% by weight of the liquid of an alcohol selected from the group comprising ethylene glycol, 1,3 propanediol, 1,2 propanediol, tetramethylene glycol, pentamethylene glycol, hexamethylene glycol, 2,3-butane diol, 1,3 butanediol, diethylene glycol, triethylene glycol, polyethylene glycol, glycerol formal, dipropylene glycol, polypropylene glycol, dipropylene glycol n-butyl ether, and mixtures thereof; and from about 10% to about 30% by weight of the composition of a non-amine neutralized linear alkylbenzene sulphonate and wherein the liquid laundry detergent composition comprises less than about 10% by weight of the liquid laundry detergent composition of an amine-neutralised anionic surfactant; and wherein the composition comprises between about 0.5% and about 20% by weight of the composition of water; and wherein the composition comprises less than about 5% by weight of the composition of a hydroxyl-containing amine.

2 . The detergent composition according to claim 1 wherein the soil release polymer is a polyester soil release polymer.

3 . The detergent composition according to claim 2 , wherein the polyester soil release polymer is selected from the group comprising terephthalate polymers, amine polymers, or mixtures thereof.

4 . The detergent composition according to claim 1 , wherein the brightener is selected from stilbene brighteners, hydrophobic brighteners and mixtures thereof.

5 . The detergent composition according to claim 1 , wherein the polycarboxylate polymer is selected from a maleate/acrylate random copolymer or polyacrylate homopolymer,or a co-polymer that comprises: (i) from about 50 to less than about 98 wt % structural units derived from one or more monomers comprising carboxyl groups; (ii) from about 1 to less than about 49 wt % structural units derived from one or more monomers comprising sulfonate moieties; and (iii) from about 1 to about 49 wt % structural units derived from one or more types of monomers selected from ether bond-containing monomers represented by formulas (I) and (II):

wherein in formula (I), R 0 represents a hydrogen atom or CH 3 group, R represents a CH 2 group, CH 2 CH 2 group or single bond, X represents a number 0-5 provided X represents a number 1-5 when R is a single bond, and R 1 is a hydrogen atom or C 1 to C 20 organic group;

wherein in formula (II), R 0 represents a hydrogen atom or CH 3 group, R represents a CH 2 group, CH 2 CH 2 group or single bond, X represents a number 0-5, and R 1 is a hydrogen atom or C 1 to C 20 organic group.

6 . The detergent composition according to claim 1 , wherein the composition has an equilibrium relative humidity of less than about 65% at about 20° C.

7 . The detergent composition according to claim 1 , wherein the liquid phase comprises between about 5% and about 20%by weight of the composition of the alcohol.

8 . The detergent composition according to claim 7 , wherein the liquid phase comprises between about 5% and about 15% by weight of the composition of the alcohol.

9 . The detergent composition according to claim 1 , wherein the liquid phase comprises alkyl sulphate anionic surfactant, natural or synthetically derived fatty alcohol ethoxylate non-ionic surfactant or mixtures thereof.

10 . The detergent composition according to claim 1 comprising from about 0.1% to about 4% by weight of the composition of a hydroxyl-containing amine.

11 . The detergent composition according to claim 1 wherein the amine is selected from the group comprising monoethanol amine, triethanolamine, and mixtures thereof.

12 . The detergent composition according to claim 1 comprising a structurant.

13 . The detergent composition according to claim 1 , wherein the solid is in particulate form and wherein the particles have a mean particle size distribution of between about 2 μm and about 50 μm.

14 . The detergent composition according to claim 1 comprising a perfume raw material, wherein the perfume raw material is selected from aldehydes, ketones or a mixture thereof.

15 . The detergent composition according to claim 1 comprising between about 20% and about 40% by weight of the composition of an adjunct ingredient, wherein the adjunct ingredient is selected from the group comprising bleach, bleach catalyst, dye, hueing dye, cleaning polymers including alkoxylated polyamines and polyethyleneimines, surfactant, solvent, dye transfer inhibitors, chelant, enzyme, perfume, encapsulated perfume, cellulosic polymers and mixtures thereof.

16 . A water-soluble unit dose article comprising a water-soluble film and a detergent composition according to claim 1 wherein the composition comprises between about 0.5% and about 15% by weight of the composition of water.

17 . The unit dose article according to claim 16 wherein the unit dose article comprises at least two compartments.

18 . The unit dose article according to claim 17 wherein the unit dose article comprises at least three compartments

19 . The unit dose article according to claim 18 wherein the unit dose article comprises at least four compartments.

20 . A process of making a composition according to claim 1 , comprising the step of adding the solid wherein the solid comprises particles wherein the particles have a mean particle size distribution of less than about 500 μm.
