Abstract

Liquid laundry detergent compositions comprising a first and second polymer. Water-soluble unit dose articles containing such compositions. Related methods.

Claims

1. A liquid laundry detergent composition comprising:

a. between about 5% and about 35% by weight of the liquid laundry detergent composition of an amine neutralised C_12-14 linear alkylbenzene sulphonate;

b. between about 0.05% and about 3% by weight of the liquid laundry detergent composition of a first polymer, wherein the first polymer is a cationically modified polysaccharide;

c. between about 0.05% and about 3% by weight of the liquid laundry detergent composition of a second polymer, wherein the second polymer is a cellulosic polymer that is a hydrophobically modified carboxymethylcellulose having a degree of substitution (DS) of from about 0.01 to about 0.99 and a degree of blockiness (DB) such that either DS+DB is at least about 1.00 and/or DB+2DS−

DS² is at least about 1.20.

2. The liquid laundry detergent composition according to claim 1, wherein the first polymer is selected from cationic guar gums, cationic cellulosic polymers, and mixtures thereof.

3. The liquid laundry detergent composition according to claim 2, wherein the first polymer is selected from cationically modified hydroxyethyl cellulose, cationically modified hydroxypropyl cellulose, cationically and hydrophobically modified hydroxyethyl cellulose, cationically and hydrophobically modified hydroxypropyl cellulose, or a mixture thereof.

4. The liquid laundry detergent composition according to claim 3, wherein the first polymer is selected from cationically modified hydroxyethyl cellulose, cationically and hydrophobically modified hydroxyethyl cellulose, or a mixture thereof.

5. The liquid laundry detergent composition according to claim 1 comprising:

a. between about 5% and about 30% by weight of the liquid laundry detergent composition of the amine neutralised C_12-14 linear alkylbenzene sulphonate, wherein the amine is an alkanolamine, selected from monoethanolamine, diethanolamine, triethanolamine or a mixture thereof, or

b. between about 5% and about 35% by weight of the liquid laundry detergent composition of an amine neutralised C_12-14 linear alkylbenzene sulphonate, wherein the amine is an alkanolamine, selected from monoethanolamine, diethanolamine, triethanolamine or a mixture thereof.

6. The liquid laundry detergent composition according to claim 1 comprising between about 0.1% and about 2% by weight of the liquid laundry detergent composition of the first polymer.

7. The liquid laundry detergent composition according to claim 1 comprising between about 0.1% and about 2% by weight of the liquid laundry detergent composition of the second polymer.

8. The liquid laundry detergent composition according to claim 1 further comprising brightener, a hueing dye, an enzyme or a mixture thereof.

9. The liquid laundry detergent composition according to claim 1 comprising between about 5% and about 35% by weight of the liquid laundry detergent composition of alkyl sulphate, alkoxylated alkyl sulphate, or a mixture thereof.

10. The liquid laundry detergent composition according to claim 9, wherein the alkyl sulphate, alkoxylated alkyl sulphate or a mixture thereof is neutralised with an amine, selected from monoethanolamine, diethanolamine, triethanolamine or a mixture thereof.

11. The liquid laundry detergent composition according to claim 1 further comprising between about 1% and about 25% by weight of the liquid laundry detergent composition of a non-ionic surfactant.

12. The liquid laundry detergent composition according to claim 11 wherein the non-ionic surfactant is selected from a fatty alcohol alkoxylate, an oxo-synthesised fatty alcohol alkoxylate, Guerbet alcohol alkoxylates, alkyl phenol alcohol alkoxylates or a mixture thereof.

13. The liquid laundry detergent composition according to claim 1 comprising between about 1.5% and about 20% by weight of the liquid detergent composition of soap.

14. A water-soluble unit dose article comprising a water-soluble film and a liquid detergent composition according to claim 1.

15. The water-soluble unit dose article according to claim 14 wherein the water-soluble unit dose article comprises at least two compartments.

16. A method of washing comprising the steps of adding the liquid laundry detergent composition according to claim 1 to sufficient water to dilute the liquid laundry detergent composition by a factor of at least about 300-fold to create a wash liquor and contacting fabrics to be washed with said wash liquor.
