Claim 0:
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. from about 15% to about 55% by weight of the laundry detergent composition of a non-soap anionic surfactant;
b. from about 2.5% to about 30% by weight of the laundry detergent composition of a non-ionic surfactant;
wherein the non-ionic surfactant comprises:
(i) a first alkoxylated alcohol non-ionic surfactant according to structure:

R1—O-(AO1)n-(AO2)m-(AO3)z—H,  (I)

wherein AO1 is a first alkoxy chain selected from an ethoxylate chain, a propoxylate chain or a butoxylate chain, AO2 is a second alkoxy chain selected from an ethoxylate chain, a propoxylate chain or a butoxylate chain, AO3 is a third alkoxy chain selected from an ethoxylate chain, a propoxylate chain or a butoxylate chain and wherein AO1 and AO2 are different from one another, and wherein if AO3 is present, then AO2 and AO3 are different from one another; R1 is a linear or branched alkyl chain having an average of from about 8 to about 18 carbon atoms; n is from about 1-30, m is from about 1-30 and z is from about 0-30, and sum total of n+m+z is at least about 10; and

(ii) between about 2% and about 10% by weight of the laundry detergent composition of a second alkoxylated alcohol non-ionic surfactant according to structure:

R2—O-(EO)p—H,  (II)

wherein, EO is an ethoxylate chain; R2 is a linear or branched alkyl chain having an average of from about 8 to about 18 carbon atoms; p is from about 1-30, and

 wherein the laundry detergent composition comprises between about 2.5% and about 20%, by weight of the detergent composition, of the first alkoxylated alcohol non-ionic surfactant, and between about 2% and about 8%, by weight of the detergent composition, of the second alkoxylated alcohol non-ionic surfactant, and
 wherein the weight ratio of the first alkoxylated non-ionic surfactant to the second alkoxylated non-ionic surfactant is from about 1:1 to about 7:1, and
 wherein the water-soluble film comprises a blend of a polyvinylalcohol homopolymer and a carboxylated anionic polyvinylalcohol copolymer.
