Abstract
Official abstract text for this publication.
The aim of the invention is to improve the primary detergent power of detergents and cleaning products, in particular with respect to soiling containing oil and/or grease. For this purpose, copolymers including ethylenically unsaturated carboxylic acid-derived sulfobetaine units and hydroxyalkyl(meth)acrylic acid esters are incorporated into the products.
First claim
Opening claim text (preview).
What is claimed is: 1. A detergent or cleaning product containing a polymer obtainable by copolymerization of: (A) 2-hydroxyethyl methacrylate, with (B) N-(2-(methacryloxyethyl)-N,N-dimethyl-N-(3-sulfopropyl)ammonium betaine, and wherein the molar ratio of A to B is from 75:25 to 25:75, wherein the detergent or cleaning product further comprises alkylbenzene sulfonate having linear C 9-13 alkyl groups and wherein the weight ratio of linear alkylbenzene sulfonate to polymer consisting of the units A and B lies in the range from 8:1 to 2:1. 2. The detergent or cleaning product according to claim 1 , wherein the polymer consisting of the units A and B has an average molecular weight in the range from 2000 g/mol to 100,000 g/mol. 3. The product according to claim 1 , wherein it contains 0.1% by weight to 10% by weight, of polymer consisting of the units A and B. 4. A method for removing soiling from textiles or hard surfaces comprising the step of bringing the textile or the hard surface into contact with an aqueous liquor which comprises a detergent or cleaning product according to claim 1 . 5. The method according to claim 4 , wherein the concentration of polymer consisting of the units A and B in the liquor lies in the range from 0.01 g/l to 0.5 g/l.
