Patent ID: 8821845

Claim:
A concentrated ingredient for treating and/or modifying surfaces, comprising: a) a conditioning agent, b) an ampholytic copolymer comprising: 0.1% to 50% of the units of said copolymer are units B CAT derived from the polymerization of at least one monomer compound B CAT of general formula I: in which: R 1 is a hydrogen atom or a methyl or ethyl group; R 2 , R 3 , R 4 , R 5 and R 6 , which are identical or different, are linear or branched C 1 -C 6 and optionally C 1 -C 4 alkyl, hydroxyalkyl or aminoalkyl groups, m is an integer from 0 to 10; n is an integer from 1 to 6; Z represents a —C(O)O— or —C(O)NH— group or an oxygen atom; A represents a group (CH 2 ) p , p being an integer from 1 to 6; B represents a linear or branched C 2 -C 12 polymethylene chain, optionally interrupted with one or more heteroatoms or hetero groups, and optionally substituted with one or more hydroxyl or amino groups, X − , which are identical or different, represent counterions; and 50% to 99.9% of the units of said copolymer are units B A and, optionally, units B N , said units B A being derived from the polymerization of at least one hydrophilic monomer B A bearing a function of acidic nature that is copolymerizable with B CAT , which is anionic or potentially anionic; and said units B N being derived from at least one ethylenically unsaturated monomer B N of neutral charge bearing one or more hydrophilic groups, which is copolymerizable with B CAT and B A ; wherein the total amount of units B A and optionally B N being from 50% to 99.9% by number, c) optionally a surfactant, and d) optionally water, wherein: the total weight amount of products a) and b) in the ingredient is at least 10%, and the weight ratio of product c), if it is present, to product a) is less than 1.0.
