The unit dose pacs include a water-soluble container formed from a water-soluble or water-dispersible film and a wash composition encapsulated in the container. According to one embodiment, the wash composition includes an anionic surfactant present at from about 2% to about 35%, a non-ionic surfactant present at from about 2% to about 30%, and a solvent system present at from about 37.5% to about 80%, characterized in that the solvent system is composed of water and a single non-aqueous solvent only, or composed of water, a single non-aqueous solvent, and a residual solvent (less than 5%) only. ## Claims ### Claim 1 A unit dose pac comprising: a container formed from a water-soluble or water-dispersible film; and a liquid composition entrapped in the container, wherein the liquid composition is free of glycerin, propylene glycol and polyethylene glycol having a weight average molecular weight of about 400 g/mol and comprises: (a) a beneficial composition comprising a C12-C14 alkyl ethoxylated sulphate in an amount of from about 8% to about 20% actives by weight of the liquid composition, and a C12-C15 alcohol ethoxylate in an amount of from about 20% to about 25% by weight of the liquid composition; and (b) a solvent system comprising water in an amount of 24 to 25% by weight of the liquid composition, a single non-aqueous solvent selected from the group consisting of polyethylene glycol having a weight average molecular weight of about 3350 g/mol and polyethylene glycol 100 stearate and present in an amount of 25% by weight of the liquid composition, and a residual solvent comprising ethanol in an amount of from 0 to 5% by weight of the liquid composition. ### Claim 2 (depends on 1) The unit dose pac of claim 1, wherein the non-aqueous solvent is polyethylene glycol having a weight average molecular weight of about 3350 g/mol. ### Claim 3 (depends on 1) The unit dose pac of claim 1, wherein the non-aqueous solvent is PEG 100 stearate. ### Claim 4 (depends on 1) The unit dose pac of claim 1, wherein the ethanol is present in an amount of about 3% by weight of the liquid composition. ### Claim 5 (depends on 1) The unit dose pac of claim 1 wherein the C12-C14 alkyl ethoxylated sulphate is further defined as CH3(CH2)10-12CH2(OCH2CH2)3OSO3Na. ### Claim 6 (depends on 5) The unit dose pac of claim 5 wherein the C12-C14 alkyl ethoxylated sulphate is present in an amount of about 15% to about 16% actives by weight of the liquid composition. ### Claim 7 (depends on 1) The unit dose pac of claim 1 wherein the C12-C14 alkyl ethoxylated sulphate is present in an amount of about 15% to about 16% actives by weight of the liquid composition. ### Claim 8 (depends on 1) The unit dose pac of claim 1 wherein the C12-C15 alcohol ethoxylate is further defined as C12-C15 alcohol ethoxylate 7 EO. ### Claim 9 (depends on 8) The unit dose pac of claim 8 wherein the C12-C15 alcohol ethoxylate is present in an amount of about 23% by weight of the liquid composition. ### Claim 10 (depends on 1) The unit dose pac of claim 1 wherein the C12-C15 alcohol ethoxylate is present in an amount of about 23% by weight of the liquid composition. ### Claim 11 (depends on 1) The unit dose pac of claim 1 wherein the C12-C14 alkyl ethoxylated sulphate is further defined as CH3(CH2)10-12CH2(OCH2CH2)3OSO3NA; the C12-C14 alkyl ethoxylated sulphate is present in an amount of about 15% to about 16% actives by weight of the liquid composition; the C12-C15 alcohol ethoxylate is further defined as C12-C15 alcohol ethoxylate 7 EO; and the C12-C15 alcohol ethoxylate is present in an amount of about 23% by weight of the liquid composition. ### Claim 12 (depends on 11) The unit dose pac of claim 11 wherein the ethanol is present in an amount of about 3% by weight of the liquid composition. ### Claim 13 (depends on 11) The unit dose pac of claim 11 wherein the solvent system consists of the water, the single non-aqueous solvent, and the residual solvent. ### Claim 14 (depends on 13) The unit dose pac of claim 13, wherein the is ethanol is present in an amount of about 3% by weight of the liquid composition. ### Claim 15 (depends on 14) The unit dose pac of claim 14, wherein the non-aqueous solvent is PEG 100 stearate. ### Claim 16 (depends on 14) The unit dose pac of claim 14, wherein the non-aqueous solvent is polyethylene glycol having a weight average molecular weight of about 3350 g/mol. ### Claim 17 (depends on 1) The unit dose pac of claim 1 wherein the solvent system consists of the water, the single non-aqueous solvent, and the residual solvent. ### Claim 18 (depends on 17) The unit dose pac of claim 17, wherein the is ethanol is present in an amount of about 3% by weight of the liquid composition. ### Claim 19 (depends on 18) The unit dose pac of claim 18, wherein the non-aqueous solvent is PEG 100 stearate. ### Claim 20 (depends on 18) The unit dose pac of claim 18, wherein the non-aqueous solvent is polyethylene glycol having a weight average molecular weight of about 3350 g/mol.
