Abstract: Use of water-soluble or water-dispersible polymers which can be obtained by oxidation of polymers which contain as copolymerised units at least 10 mol % of ethylenically unsaturated monomers having carboxyl groups, and which have K values of 8 to 300 (determined by the method of H. Fikentscher in aqueous solution at 25 DEG C and pH 7 on the Na salt of the polymers at a concentration of 1% by weight), as additive to detergents and cleaning agents in amounts of 0.1 to 15% of the weight of the particular formulation.

Abstract: Alkyl glucoside amino carboxylates of the formula in which at least two R substituents are or H, L is an iminodiacetate, aspartate, glutamate, sarcosinate, glycinate, serinate, hydroxyaspartate, ethanolaminoacetate, diethanolamino, alanate or taurinate residue, X is hydrogen, alkali metal, ammonium or substituted ammonium ion, R is R is H or -CH3 and n is 0 to 4, preparation of the compounds of the formula I by esterification of (a) hydroxyalkyl glucosides with (b) maleic anhydride in the molar ratio (a):(b) of 1:at least 2 to 5.5 and addition of amines or amino acids of the formula L-H, in which L has the abovementioned meaning, onto the double bonds of the esters. The compounds of the formula I are used as complexing agents for heavy metal ions.

Abstract: Use of graft polymers which are obtainable by grafting (a) polyvinylpyrrolidone having a molecular weight (based on the viscosity average) of 500 to 150,000 with (b) at least one vinyl ester, which is derived from a saturated monocarboxylic acid containing 1 to 6 C atoms, and/or methyl or ethyl (meth)acrylate in a weight ratio (a) : (b) of 1 : 0.5 to 1 : 10, as greying inhibitors in the washing and aftertreament of textile material containing manmade fibres.

Abstract: 2-(1-Hydroxycarbalkoxymethyl)-acrylonitriles and 2-(1-hydroxycarbalkoxymethyl)-acrylates are prepared by a process in which an acrylonitrile or an acrylate is reacted with a glyoxylate in an aqueous medium at a pH greater than or equal to 6, in the presence of a tertiary amine as a catalyst.
