Abstract

Liquid laundry detergent compositions. Water-soluble unit dose articles that include a gel and a particle.

First claim

What is claimed is:

1. A liquid laundry detergent composition comprising:
a gel, wherein the gel comprises:
a) lamellar phase composition;
b) a particle comprising an active material; and
c) optionally a viscous hydrophobic ingredient, wherein

1) the lamellar phase composition comprises a mixture comprising one or more surfactants and a material selected from a fatty acid, a fatty alcohol, or a mixture thereof, wherein the mixture is in lamellar phase,
2) the viscous hydrophobic ingredient, if present, comprises silicone and/or petrolatum, and
3) the liquid laundry detergent composition comprises less than about 20%, by weight of the liquid laundry detergent composition, of water.

2. A liquid laundry detergent composition according to claim 1 , wherein the liquid laundry detergent composition comprises between about 10% and about 100%, by weight of the liquid laundry detergent composition, of the gel.

3. A liquid laundry detergent composition according to claim 2 , wherein the liquid laundry detergent composition comprises between about 15% and about 80%, by weight of the liquid laundry detergent composition, of the gel.

4. A liquid laundry detergent composition according to claim 3 , wherein the liquid laundry detergent composition comprises between about 20% and about 60%, by weight of the liquid laundry detergent composition, of the gel.

5. A liquid laundry detergent composition according to claim 1 , wherein the gel comprises between about 50% and about 90%, by weight of the gel, of the lamellar phase composition.

6. A liquid laundry detergent composition according to claim 5 , wherein the gel comprises between about 60% and about 80%, by weight of the gel, of the lamellar phase composition.

7. A liquid laundry detergent composition according to claim 6 , wherein the gel comprises about 65%, by weight of the gel, of the lamellar phase composition.

8. A liquid laundry detergent composition according to claim 1 , wherein the lamellar phase composition comprises between about 24% and about 43%, by weight of the lamellar phase composition, of the surfactant.

9. A liquid laundry detergent composition according to claim 8 , wherein the lamellar phase composition comprises between about 29% and about 38%, by weight of the lamellar phase composition, of the surfactant.

10. A liquid laundry detergent composition according to claim 1 , wherein the surfactant is selected from the group consisting of alkyl benzene sulphonate, alkyl ethoxylated sulphate, and mixtures thereof.

11. A liquid laundry detergent composition according to claim 1 , wherein the lamellar phase composition comprises between about 12% and about 23%, by weight of the lamellar phase composition, of the material selected from a fatty acid, a fatty alcohol, or a mixture thereof.

12. A liquid laundry detergent composition according to claim 11 , wherein the lamellar phase composition comprises between about 15% and about 20%, by weight of the lamellar phase composition, of the material selected from a fatty acid, a fatty alcohol, or a mixture thereof.

13. A liquid laundry detergent composition according to claim 1 , wherein the gel comprises between about 0.25% and about 3%, by weight of the gel, of the particle.

14. A liquid laundry detergent composition according to claim 13 , wherein the gel comprises between about 0.5% and about 2%, by weight of the gel, of the particle.

15. A liquid laundry detergent composition according to claim 1 , wherein the particle is in a form of a core/shell capsule in which the active material is comprised within a core of the core/shell capsule, wherein the active material is comprised within a carrier material or on the carrier material, or a mixture thereof.

16. A liquid laundry detergent composition according to claim 1 , wherein the particle is an agglomerate, an extrudate, a spray-dried particle, an aqueous slurry, or a mixture thereof.

17. A liquid laundry detergent composition according to claim 1 , wherein the active material is selected from chelants, cellulosic polymer, perfume microcapsules, enzymes, or mixtures thereof.

18. A liquid laundry detergent composition according to claim 1 , comprising between about 5% and about 15%, by weight of the liquid laundry detergent composition, of water.

19. A liquid laundry detergent composition according to claim 1 , wherein the gel is present in a form of droplets dispersed within the liquid laundry detergent composition.

20. A water-soluble unit dose article comprising a water-soluble film and a first internal compartment, wherein the first internal compartment comprises a first liquid laundry detergent composition, wherein the first liquid laundry detergent composition is a liquid laundry detergent composition according to claim 1 .

21. A water-soluble unit dose article according to claim 20 , wherein the water-soluble unit dose article comprises a second internal compartment, wherein the second internal compartment comprises a second composition.
