Abstract

Claims (31)

1 . A water-soluble unit dose article comprising a water-soluble film and a liquid laundry detergent composition;

wherein the liquid laundry detergent composition comprises a non-ionic surfactant, wherein the non-ionic surfactant comprises an ethoxylated alcohol non-ionic surfactant, wherein the ethoxylated alcohol non-ionic surfactant comprises a narrow range ethoxylated alcohol non-ionic surfactant;

wherein the narrow range ethoxylated alcohol non-ionic surfactant comprises an alkyl chain having an average of from about 8 to about 18 carbon atoms;

wherein the narrow range ethoxylated alcohol non-ionic surfactant has an average degree of ethoxylation between about 5 and about 12; and

wherein the narrow range ethoxylated alcohol non-ionic surfactant comprises polyethoxy groups, and wherein at least about 85% by weight of the total narrow range ethoxylated alcohol surfactant are ethoxylated alcohol non-ionic surfactant molecules comprising a polyethoxy group comprising between about 5 and about 12 ethoxy groups,

wherein the ethoxylated alcohol non-ionic surfactant comprises between about 1% and about 50% by weight of the ethoxylated alcohol non-ionic surfactant of a broad range ethoxylated alcohol non-ionic surfactant;

wherein the narrow range ethoxylated alcohol non-ionic surfactant and the broad range ethoxylated alcohol non-ionic surfactant in a relative weight ratio of about 10:1 to about 1:1; and

wherein the liquid laundry detergent composition comprises between about 1% and about 20% by weight of the liquid laundry detergent composition of water.

2 . The water-soluble unit dose article according to claim 1 , wherein the narrow range ethoxylated alcohol non-ionic surfactant comprises a linear narrow range ethoxylated alcohol non-ionic surfactant, a branched narrow range ethoxylated alcohol non-ionic surfactant, or a mixture thereof.

3 . The water-soluble unit dose article according to claim 1 , wherein the narrow range ethoxylated alcohol non-ionic surfactant comprises a primary alcohol based narrow range ethoxylated alcohol non-ionic surfactant, a secondary alcohol based narrow range ethoxylated alcohol non-ionic surfactant, or a mixture thereof.

4 . The water-soluble unit dose article according to claim 1 wherein the liquid laundry detergent composition comprises between about 3% and about 30% by weight of the liquid laundry detergent composition of the ethoxylated alcohol non-ionic surfactant.

5 . The water-soluble unit dose article according to claim 1 wherein the ethoxylated alcohol non-ionic surfactant comprises between about 50% and about 99% by weight of the ethoxylated alcohol non-ionic surfactant of the narrow range ethoxylated alcohol non-ionic surfactant.

6 . The water-soluble unit dose article according to claim 1

wherein the broad range ethoxylated alcohol non-ionic surfactant comprises an alkyl chain having an average of from about 8 to about 18 carbon atoms;

wherein the broad range ethoxylated alcohol non-ionic surfactant comprises polyethoxy groups, and wherein between about 15% and about 45% by weight of the total broad range ethoxylated alcohol surfactant are ethoxylated alcohol non-ionic surfactant molecules comprising a polyethoxy group comprising between about 6 and about 10 ethoxy groups, and

and wherein between about 30% and about 70% by weight of the total broad range ethoxylated alcohol surfactant are ethoxylated alcohol non-ionic surfactant molecules comprising a polyethoxy group comprising between about 5 and about 12 ethoxy groups.

7 . The water-soluble unit dose article according to claim 6 wherein the broad range ethoxylated alcohol non-ionic surfactant comprises a linear broad range ethoxylated alcohol non-ionic surfactant, a branched broad range ethoxylated alcohol non-ionic surfactant, or a mixture thereof, and wherein the broad range ethoxylated alcohol non-ionic surfactant comprises a primary alcohol broad range ethoxylated alcohol non-ionic surfactant, a secondary alcohol broad range ethoxylated alcohol non-ionic surfactant, or a mixture thereof.

8 . The water-soluble unit dose article according to claim 6 , wherein

i) the narrow range ethoxylated alcohol non-ionic surfactant is derived from a natural alcohol source, a synthetic alcohol source, or a mixture thereof,

ii) the broad range ethoxylated alcohol non-ionic surfactant is derived from a natural alcohol source, a synthetic alcohol source, or a mixture thereof,

iii) or a mixture thereof.

9 . The water-soluble unit dose article according to claim 8 , wherein

i) the narrow range ethoxylated alcohol non-ionic surfactant is derived from a synthetic alcohol source, wherein the synthetic alcohol source is made via an oxo process, a Ziegler process, a Guerbet process, an aldol condensation process, or a mixture thereof;

ii) the broad range ethoxylated alcohol non-ionic surfactant is derived from a synthetic alcohol source, wherein the synthetic alcohol source is made via an oxo process, a Ziegler process, a Guerbet process, an aldol condensation process, or a mixture thereof;

iii) or a mixture thereof.

10 . The water-soluble unit dose article according to claim 1 , wherein the liquid laundry detergent composition comprises a non-soap anionic surfactant, wherein the non-soap anionic surfactant is selected from neutralised linear alkylbenzene sulphonate, neutralised alkyl sulphate anionic surfactant selected from neutralised alkoxylated alkyl sulphate, neutralised non-alkoxylated alkyl sulphate, and mixtures thereof, or a mixture thereof.

11 . The water-soluble unit dose article according to claim 10 , wherein the weight ratio of non-soap anionic surfactant to ethoxylated alcohol non-ionic surfactant in the liquid laundry detergent composition is between 1:1 to 20:1.

12 . The water-soluble unit dose article according to claim 10 wherein the liquid laundry detergent composition comprises a fatty acid, wherein the fatty acid is a neutralized fatty acid soap.

13 . The water-soluble unit dose article according to claim 10 , wherein the liquid laundry detergent comprises between about 5% and about 15% by weight of the liquid detergent composition of water.
