Abstract:
A detergent composition comprising at least one washing base, at least one water-insoluble carboxylic acid ester and at least one amphoteric polymer comprising at least one monomeric unit chosen from (meth)acrylate and (meth)acrylamide types containing at least one fatty chain, the fatty chain containing from 8 to 30 carbon atoms,wherein the at least one amphoteric polymer results from copolymerization 1) of at least one monomer chosen from (meth)acrylate and (meth)acrylamide types of formula (Ia) and (Ib): â€ƒin which: R1 and R2, which may be identical or different, are a hydrogen atom or a methyl radical; R3, R4 and R5, which may be identical or different, are chosen from linear and branched alkyl radicals containing form 1 to 30 carbon atoms: Z is an NH group; n is an integer ranging from 2 to 5; and A is an anion derived from an organic or inorganic acid, 2) of at least one monomer chosen from (meth)acrylate and (meth)acrylamide types of formula (II) R6â€”CH&boxH;CR7â€”COOHâ€ƒâ€ƒ(II) â€ƒin which: R6 and R7, which may be identical or different, are a hydrogen atom or a methyl radical; and 3) of at least one monomer chosen from (meth)acrylate and (meth)acrylamide types of formula (III): R6â€”CH&boxH;CR7â€”COXR8â€ƒâ€ƒ(III) â€ƒin which: R6 and R7, which may be identical or different, are a hydrogen atom or a methyl radical: X is an oxygen atom; and R8 is chosen from linear and branched alkyl radicals containing from 1 to 30 carbon atoms; wherein at least one of the (meth)acrylate and (meth)acrylamide type monomers of formula (Ia), (Ib) or (III) comprise at least one fatty chain containing from 8 to 30 carbon atoms.
