Abstract:
A softening system which comprises:(a) a water soluble container which is formed from a water soluble polymer which is selected from the group consisting of polyvinyl alcohols, polyvinyl alcohol copolymers such as polyvinyl alcohol/polyvinyl pyrrolidone, partially hydrolyzed polyvinyl acetate, polyvinyl pyrrolidone, alkyl celluloses such as methyl cellulose, ethyl cellulose and propyl cellulose, ethers and esters of alkyl celluloses of alkyl celluloses, hydroxy ethyl cellulose, hydroxy propyl cellulose, carboxy methyl cellulose sodium, dextrin, maltodextrin, such as methyl cellulose, ethyl cellulose and propyl cellulose, water soluble polyacrylates, water soluble polyacrylamides and acrylic acid/maleic anhydride copolymers; (b) a fabric softener composition comprising approximately: (i) 48% to 82% of at least one amine fabric softening active compound which is selected from the group consisting of di(hydrogenated tallow) diester of methyl diethanol amine and bis(hydrogenated tallow)-methyl amine and mixtures thereof; (ii) 0.1% to 18% of an alpha hydroxy aliphatic acid selected from the group consisting of citric acid, lactic acid and glycolic acid and mixtures thereof; (iii) 0.5% to 6% of a cationic surfactant; (iv) 1 % to 9% of a cationic softener; (v) 4% to 14% of a perfume; and (vi) less than 6% of water wherein the composition do not contain an anionic sulfate surfactant, sulfonate surfactants, a hexylene glycol, amine oxide or a detergent builder salt.
