    摘要： Liquid, alkaline detergent formulations which contain as essential constituents a surfactant, water and 0.1-20% by weight of partially esterified copolymers are obtainable by the copolymerization of(a) one or more C.sub.4 -C.sub.28 -olefins and(b) ethylenically unsaturated dicarboxylic anhydrides of from 4 to 8 carbon atomsin a molar ratio of 1:1 and subsequent partial esterification of the copolymers of the reaction products(A) C.sub.1 -C.sub.30 -alcohols, C.sub.8 -C.sub.22 fatty acids, C.sub.1 -C.sub.12 -alkylphenols or secondary C.sub.2 -C.sub.30 -amines with(B) one or more C.sub.2 -C.sub.4 -alkylene oxides or tetrahydrofuranin a molar ratio of (A):(B) of from 1:2 to 1:50 and hydrolysis of the anhydride groups of the copolymer to carboxyl groups, the partial esterification of the copolymers being carried on until more than 5 to 50% of the carboxyl groups of the copolymers have been esterified.

    摘要： A surfactant-based detergent contains water-soluble copolymers which contain(a) from 99.5 to 15 mol % of one or more monoethylenically unsaturated C.sub.3 - to C.sub.6 -monocarboxylic acids,(b) from 0.5 to 20 mol % of one or more comonomers which contain two or more ethylenically unsaturated nonconjugated double bonds and have one or more --CO--OX groups where X is hydrogen, an alkali metal, one equivalent of an alkaline earth metal or ammonium,(c) from 0 to 84.5 mol % of one or more monoethylenically unsaturated C.sub.4 - to C.sub.6 -dicarboxylic acids,(d) from 0 to 20 mol % of one or more hydroxyalkyl esters of monoethylenically unsaturated C.sub.3 - to C.sub.6 -carboxylic acids and(e) from 0 to 30 mol % of other water-soluble monoethylenically unsaturated monomers copolymerizable with (a) to (d)as copolymerized units, with the proviso that the sum of the mol % ages (a) to (e) is always 100 and which have a Finkentscher K value of from 8 to 120.

    摘要： A stable liquid detergent composition having improved clay soil detergency, clay soil anti-redeposition, oily soil anti-redeposition and soil release properties is disclosed. The detergent composition is comprised of an anionic surfactant, a nonionic surfactant, a hydrotrope, a graft copolymer of polyalkylene oxide and an ester monomer, and a nonionic cellulosic anti-redeposition agent. The graft copolymer is comprised of (a) a polyalkylene oxide based upon an alkylene oxide having from 2 to 4 carbon atoms having a molecular weight of 300 to 100,000 and, (b) at least one vinyl ester derived from a saturated monocarboxylic acid containing 1 to 6 carbon atoms, and/or methyl or ethyl ester of acrylic or meth-acrylic acid in a weight ratio of (a):(b) of from 1:0.2 to 1:10. The nonionic cellulosic anti-redeposition agent is preferably hydroxypropyl methylcellulose. There is a synergism between the nonionic anti-redeposition agent and the graft polyol which imparts improved clay soil detergency, clay anti-deposition and oily soil anti-redeposition properties to the detergent composition.
