## 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.

## Claims

### Claim 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.

### Claim 2 (depends on 1)

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.

### Claim 3 (depends on 2)

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.

### Claim 4 (depends on 1)

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.

### Claim 5 (depends on 1)

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

### Claim 6 (depends on 5)

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.

### Claim 7 (depends on 1)

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

### Claim 8 (depends on 7)

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

### Claim 9 (depends on 1)

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.

### Claim 10 (depends on 9)

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.

### Claim 11 (depends on 1)

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.

### Claim 12 (depends on 1)

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.

### Claim 13 (depends on 12)

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.

### Claim 14 (depends on 1)

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, TiO2, silica and mixtures thereof.

### Claim 15 (depends on 1)

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.

### Claim 16 (depends on 1)
