Abstract

A liquid laundry detergent composition that includes a liquid phase, a lamellar liquid crystal phase, and a particulate phase, where the lamellar liquid phase and particulate phase are dispersed within the liquid phase.

First claim

What is claimed is:

1 . A liquid laundry detergent composition comprising:
a. a liquid phase; b. a lamellar liquid crystal phase; c. a particulate phase; wherein the lamellar liquid phase and particulate phase are dispersed within the liquid phase and wherein the particulate 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 term ‘lamellar liquid crystal’ means the system being in a state where the surfactant molecules are organised in stacks of bilayers of surfactant in the melted state separated by thin layers of solvent; 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 wherein the composition has an equilibrium relative humidity of less than about 65% at about 20° C. as measured via the composition eRH test described herein; and wherein the composition comprises less than about 5% by weight of the composition of a hydroxyl-containing amine compound, wherein the composition comprises between about 5% and about 35%, by weight of the composition of the lamellar liquid crystal phase, wherein the composition comprises between about 25% and about 55% by weight of the composition of the particulate phase.

2 . The detergent composition according to claim 1 , wherein the composition comprises between about 10% and about 30% by weight of the composition of the lamellar liquid crystal phase.

3 . The detergent composition according to claim 2 , wherein the composition comprises between about 12% and about 25% by weight of the composition of the lamellar liquid crystal phase.

4 . The detergent composition according to claim 1 , wherein the composition comprises between about 30% and about 50% by weight of the composition of the particulate phase.

5 . The detergent composition according to claim 1 , wherein the particulate phase comprises a particulate cleaning active.

6 . The detergent composition according to claim 5 , wherein the particulate cleaning active comprises a cellulosic polymer, a polycarboxylate polymer, a soil release polymer, a brightener, an enzyme or a mixture thereof.

7 . The detergent composition according to claim 1 , wherein the lamellar liquid crystal phase comprises a surfactant.

8 . The detergent composition according to claim 7 , wherein the anionic surfactant is selected from linear alkylbenzene sulphonate, alkyl sulphate, or a mixture thereof.

9 . 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.

10 . The detergent composition according to claim 9 , wherein the liquid phase comprises between about 5% and about 20% by weight of the composition of the alcohol.

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

12 . The detergent composition according to claim 1 comprising from about 0% to about 5%, by weight of the composition of the hydroxyl-containing amine compound.

13 . The detergent composition according to claim 12 , wherein the hydroxyl-containing amine compound is selected from the group comprising monoethanol amine, triethanolamine, and mixtures thereof.

14 . The detergent composition according to claim 1 comprising less than 2% by weight of the composition of a structurant, wherein the structurant is selected from crystallisable glyceride, cellulose-fibre based structurants, TiO 2 , silica and mixtures thereof.

15 . 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.

16 . The detergent composition according to claim 1 comprising 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, perfume, encapsulated perfume, and mixtures thereof.

17 . 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.

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

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

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