A method of making an opaque liquid detergent composition comprising the steps of; a. preparing a polymer premix, wherein the polymer premix comprises i. between 5% and 40% by weight of the polymer premix of an anionic polyester terephthalate polymer, wherein the anionic polyester terephthalate polymer has a polyester terephthalate backbone grafted with one or more anionic groups; ii. between 60% and 95% by weight of the polymer premix of a solvent, wherein the solvent is an aqueous solvent, a non-aqueous solvent or a mixture thereof; b. preparing a surfactant premix, wherein the surfactant premix comprises between 10% and 70%, preferably between 20% and 65%, more preferably between 40% and 60% by weight of the surfactant premix of a non-soap surfactant, the non-soap surfactant preferably comprising between 50% and 100% preferably between 70% and 100% more preferably between 90% and 100% by weight of the non-soap surfactant of a non-soap anionic surfactant, the non-soap anionic surfactant comprising the protonated form of the non-soap anionic surfactant, the neutralized salt form of a non-soap anionic surfactant or a mixture thereof, preferably wherein the non-soap anionic surfactant premix comprises between 50% and 90% by weight of the non-soap anionic surfactant of the neutralized salt form of a non-soap anionic surfactant; c. combining the polymer premix and the surfactant premix in a weight ratio of the polymer premix to the surfactant premix of 2:1 and 1:25, preferably between 1.5:1 and 1:10; d. mixing the polymer premix and the surfactant premix; e. Optionally adding one or more adjunct ingredients; f. Collecting the final opaque liquid detergent composition; wherein, by 'opaque' it is meant a liquid composition having less than 1% transmittance measured using a ColorQuest XE spectrophotometer, using 2.5 mL PS cuvettes (1 cm path length), measuring a range from 400 to 700 nm when measured neat. a. preparing a polymer premix, wherein the polymer premix comprises i. between 5% and 40% by weight of the polymer premix of an anionic polyester terephthalate polymer, wherein the anionic polyester terephthalate polymer has a polyester terephthalate backbone grafted with one or more anionic groups; ii. between 60% and 95% by weight of the polymer premix of a solvent, wherein the solvent is an aqueous solvent, a non-aqueous solvent or a mixture thereof; i. between 5% and 40% by weight of the polymer premix of an anionic polyester terephthalate polymer, wherein the anionic polyester terephthalate polymer has a polyester terephthalate backbone grafted with one or more anionic groups; ii. between 60% and 95% by weight of the polymer premix of a solvent, wherein the solvent is an aqueous solvent, a non-aqueous solvent or a mixture thereof; b. preparing a surfactant premix, wherein the surfactant premix comprises between 10% and 70%, preferably between 20% and 65%, more preferably between 40% and 60% by weight of the surfactant premix of a non-soap surfactant, the non-soap surfactant preferably comprising between 50% and 100% preferably between 70% and 100% more preferably between 90% and 100% by weight of the non-soap surfactant of a non-soap anionic surfactant, the non-soap anionic surfactant comprising the protonated form of the non-soap anionic surfactant, the neutralized salt form of a non-soap anionic surfactant or a mixture thereof, preferably wherein the non-soap anionic surfactant premix comprises between 50% and 90% by weight of the non-soap anionic surfactant of the neutralized salt form of a non-soap anionic surfactant; c. combining the polymer premix and the surfactant premix in a weight ratio of the polymer premix to the surfactant premix of 2:1 and 1:25, preferably between 1.5:1 and 1:10; d. mixing the polymer premix and the surfactant premix; e. Optionally adding one or more adjunct ingredients; f. Collecting the final opaque liquid detergent composition;
