Cleaning products containing copolymers

A copolymer containing the following amounts of copolymerized ethylenically unsaturated monomers: 5 to 99% by weight of one or more anionic vinyl monomers (A), from 0.01 to 50% by weight of one or more vinyl monomers (B), group containing quaternary ammonium or tertiary grupoamonio; optionally 0.5 to 80% by weight of one or more hydrophilic vinylic monomers nonionic (C) 0.1 to 15% by weight of one or more vinyl monomers polyfunctional ( F) of general formula (IX), wherein R18 is hydrogen or an alkyl group having 1 or 2 carbon atoms and n2 is a number from 1 to 20; 0 to 30% by weight of one or more monomers hydrophobic vinyl (D); Y on 0 to 20% by weight of one or more vinyl monomers (E) containing silicone moieties, the sum of the monomers (A), (B), (C), (D), (E) and (F) has to equal 100% by weight.
