摘要

591170 Disclosed is an ultra concentrated liquid laundry detergent composition comprising: from about 35 to about 55 per cent by weight of a non-ionic surfactant; from about 15 to about 25 per cent by weight of an anionic surfactant; from about 2 to about 18 per cent by weight of a cold water dispersion aid, wherein the cold water dispersion aid is selected from the group consisting of: alkaline earth metal salts, divalent metal salts, polyethylene glycol, poly-glycols, , water-miscible glycols, glycol ethers, hydrotropes, benzyl alcohol, dipropylene glycol n-butyl ether, dipropylene glycol n-propyl ether, phenoxyethanol, and mixtures ; and from about 0 to about 60 per cent by weight water. The composition wherein said nonionic surfactant is selected from the group consisting of fatty alcohol ethoxylates; fatty acid ethoxylates; alkyl phenol ethoxylates; fatty monoglyceride ethoxylates; block copolymers; ethoxylated amines; alkyl amine oxides; mono or poly saccharide alkyl ethers; propoxylated and ethoxylated fatty alcohols; propoxylated and ethoxylated fatty acids; propoxylated and ethoxylated alkyl phenols; ether terminated ethoxylates of fatty acid and fatty alcohols; fatty acid glucamides; alkyl glucosides; alkyl polyglucosides; or mixtures thereof. The composition wherein said anionic surfactant is selected from the group consisting of alkylbenzene sulfonates; alkyl ether sulfates; alkyl sulfates; alkyl and alkenyl ester sulfonates; alkyl and alkenyl sulfonates; isethionates; taurates; and mixtures thereof. An exemplary composition includes: from 35 to 55% by weight of a nonionic surfactant; from 15 to 25% by weight of an alkylbenzene sulfonate; from 2 to 12% by weight of propylene glycol; and from 0.5% to 6% by weight of magnesium sulfate heptahydrate; or wherein said composition comprises: from 35 to 45% by weight of an ethoxylate of a fatty alcohol; from 15 to 25% by weight of a triethanolamine alkylbenzene sulfonate; from 2.5 to 10% by weight of propylene glycol; from 1 to 3% by weight of magnesium sulfate heptahydrate; and from 0.1 to 0.5% by weight of a stilbene fluorescent whitening agent.
