and wherein the solid laundry detergent composition is comprised within the first internal compartment; and wherein the solid composition comprises a non-soap anionic surfactant; and wherein the solid laundry detergent composition comprises particles and wherein the particles are spray-dried particles, agglomerates, extrudates, or a mixture thereof; and wherein the solid composition at about 1 wt % dilution in deionized water at about 20° C. has an equilibrium pH in the range of from about 6.5 to about 8.8. ### Claim 2 (depends on 1) The water-soluble unit dose article according to claim 1 wherein the non-soap anionic surfactant comprises linear alkylbenzene sulphonate, alkoxylated alkyl sulphate or a mixture thereof. ### Claim 3 (depends on 2) The water-soluble unit dose article according to claim 2 wherein the weight ratio of linear alkylbenzene sulphonate to alkoxylated alkyl sulphate is from about 1:2 to about 20:1. ### Claim 4 (depends on 1) The water-soluble unit dose article according to claim 1, wherein the solid laundry detergent composition comprises between about 20% and about 75% by weight of the solid laundry detergent composition of the non-soap anionic surfactant. ### Claim 5 (depends on 1) The water-soluble unit dose article according to claim 1 wherein the solid laundry detergent composition comprises an adjunct ingredient, wherein the adjunct ingredient is selected from non-ionic surfactants, cationic polymers, brightener, dye transfer inhibitors, chelants, enzymes, acrylate-based polymers, perfumes and perfume capsules, polyester terephthalate polymers, PEG-based polymers, ethoxylated polyethyleneimines, polysaccharides, amine oxide, aesthetic dyes, hueing dyes, antifoams, or a mixture thereof. ### Claim 6 (depends on 1) The water-soluble unit dose article according to claim 1 wherein the equilibrium pH is between about 6.7 and about 8.5. ### Claim 7 (depends on 1) The water-soluble unit dose article according to claim 1 wherein the agglomerates comprise non-soap surfactant, sodium sulphate and silica. ### Claim 8 (depends on 1) The water-soluble unit dose article according to claim 1 wherein the solid laundry detergent composition is a free flowing particulate solid, a compressed particulate solid or a mixture thereof and has a mean particle size between about 400 microns and about 1000 microns. ### Claim 9 (depends on 1) The water-soluble unit dose article according to claim 1 wherein the solid laundry detergent composition has a bulk density of between about 400 and about 1000 g/l. ### Claim 10 (depends on 9) The water-soluble unit dose article according to claim 9 wherein the solid laundry detergent composition has a bulk density of between about 500 and about 800 g/l. ### Claim 11 (depends on 1) The water-soluble unit dose article according to claim 1 wherein the first compartment comprises between about 1 g and about 25 g of the solid laundry composition. ### Claim 12 (depends on 11) The water-soluble unit dose article according to claim 11 wherein the first compartment comprises between about 5 g and about 20 g of the solid laundry composition. ### Claim 13 (depends on 1) The water-soluble unit dose article according to claim 1 wherein the water-soluble film comprises a blend of polyvinylalcohol polymers and/or polyvinylalcohol copolymers. ### Claim 14 (depends on 13) The water-soluble unit dose article according to claim 13 wherein the water-soluble film comprises a blend of polyvinylalcohol polymers and/or polyvinylalcohol copolymers selected from sulphonated and carboxylated anionic polyvinylalcohol copolymers. ### Claim 15 (depends on 1) The water-soluble unit dose article according to claim 1 wherein the water-soluble unit dose article comprises at least a first compartment and a second compartment. ### Claim 16 (depends on 15) The water-soluble unit dose article according to claim 15 wherein the water-soluble unit dose article comprises at least a first compartment, a second compartment and a third compartment. ### Claim 17 (depends on 15) The water-soluble unit dose article according to claim 15 wherein the compartments are arranged in a side-by-side arrangement, a superposed arrangement or a mixture thereof. ### Claim 18 (depends on 16) The water-soluble unit dose article according to claim 16 wherein at least the second compartment, the third compartment or both comprise a liquid. ### Claim 19 (depends on 1) A method of washing comprising the steps of adding the water-soluble unit dose article according to claim 1 to sufficient water to dilute the solid 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. ### Claim 20 A water-soluble unit dose article comprising a water-soluble film and a solid laundry detergent composition, wherein the water-soluble film defines a first internal compartment; and wherein the solid laundry detergent composition is comprised within the first internal compartment; and wherein the solid composition comprises a non-soap anionic surfactant; and wherein the solid laundry detergent composition has a bulk density of between about 400 and about 1000 g/l; and wherein the solid composition at about 1 wt % dilution in deionized water at about 20° C. has an equilibrium pH in the range of from about 6.5 to about 8.8. ### Claim 21 A water-soluble unit dose article comprising a water-soluble film and a solid laundry detergent composition, wherein the water-soluble film defines a first internal compartment; and wherein the solid laundry detergent composition is comprised within the first internal compartment; and wherein the solid composition comprises a non-soap anionic surfactant; and wherein the first compartment comprises between about 1 g and about 25 g of the solid laundry composition; and wherein the solid composition at about 1 wt % dilution in deionized water at about 20° C. has an equilibrium pH in the range of from about 6.5 to about 8.8.
