Patent ID: 7331355

Claim:
An aqueous floor cleaning composition wherein said composition comprises: a) at least one polymer selected from: 1. a copolymer comprising a first and a second set of monomer units, wherein said first set of monomer units is selected from the group consisting of acrylate, substituted acrylate monomers, and mixtures thereof, and wherein said second set of monomers is selected from the group consisting of styrene, substituted styrene monomers, and mixtures thereof, wherein said copolymer has a weight ratio of the first set of monomers to the second set of monomers from about 2:1 to about 1:2, and wherein said copolymer has an average molecular weight of less than about 20,000, and wherein said copolymer is present in the composition at a level of about 0.01% to about 1.0% by weight of said composition; 2. chitosan having an average molecular weight from about 5,000 to about 500,000, wherein said chitosan is present in the composition at a level of about 0.01% to about 1.0% by weight of said composition; and 3. mixtures thereof; and b) from about 0.005% to about 0.5%, by weight of said composition, of one or more surfactants; wherein the aqueous floor cleaning composition has a pH of about 6.5 to about 11.
