Abstract:
1. A method of preparing a unit dose fabric treatment product comprising: preparing a liquid fabric treatment composition comprising one or more soaps and a plasticizer from a premix composition comprising (a) an ester-containing soap precursor, (b) a base material, (c) optionally a solvent, and (d) water, wherein the amount of water in the premix composition is from 0.1 to 20 wt % of the premix composition, wherein components (a), (b) and (c) are reacted together, in the presence of the water, at a reaction temperature of from 50 to 100° C. to produce the one or more soaps and the plasticizer; and placing the liquid fabric treatment composition in a water soluble container which is formed from a water soluble polymer selected from the group consisting of polyvinyl alcohols, polyvinyl alcohol copolymers, partially hydrolyzed polyvinyl acetate, polyvinyl pyrrolidone, alkyl celluloses, ethers and esters of alkyl cellulosics, hydroxyl alkyl, carboxy methyl cellulose sodium, dextrin, maltodextrin, water soluble poly-acrylates, water soluble polyacrylamides and acrylic acid/maleic anhydride copolymers.
