Liquid detergent composition

Abstract

Abstract PURPOSE:To provide the title compsn. which is excellent in phase stability, and which comprises a mixture of an anon activator and a nonion activator, a particular copolymer, a salt of a low MW org. polybasic carboxylic acid, and a solubilizing agent. CONSTITUTION:An alkylene (a) of the formula (wherein R1-R4 are each H or a 1-10C alkyl with the proviso that the sum of carbon atoms of R1-R4 is 4 or more; M is H, an alkali metal, ammonium or a cation derived from a water-soluble amine; m is about 50mol.%; and n is 10-200) is copolymerized with maleic anhydride (b) in a molar ratio of (b) to (a) of about 1:1, thereby obtaining a water-soluble copolymer (C) having a degree of polymn. of 10-200 (as determined according to the vapor pressure equilibrium method). 15-50wt.% (hereinafter simply %) mixture of anion activator (A) (e.g., sodium dodecylbenzenesulfonate) and a nonion activator (B) (e.g., polyoxyethylene lauryl ether) wherein the A to B wt. ratio is 3-1/1-3, 0.1-5% component (C), 1-10% salt of a low-MW org. polybasic carboxylic acid (D) (e.g., sodium citrate), 1-10% solubilizing agent (E) (e.g., ethanol), and optionally water, an enzyme, a dye, a perfume, etc. (F) are mixed together.
