Patent ID: 8741831

Claim:
A hard surface cleaning composition comprising about 0.01 to about 5 wt. % of a terpolymer formed from monomer components consisting of a), b) c) and optionally d) wherein a) is defined as a monomer having the following structure (I): wherein R 1 and R 4 independently represent a hydrogen atom or a linear or branched C 1 -C 6 alkyl group: R 2 and R 3 independently represent an alkyl, hydroxyalkyl or amino alkyl group in which the alkyl group is a linear or branched C 1 -C 6 chain; n and m independently represent integers between 1 and 3; X − represents a counterion; b) at least one hydrophilic monomer bearing a function of acidic nature which is copolymerizable with (a) and capable of ionizing in the application medium and is selected the from group consisting of acrylic acid and methacrylic acid, c) is selected from the group consisting of acrylamide and methacrylamide; and d) optionally, a crosslinking agent, wherein monomer c) makes up at least 60 wt. % based on the total weight of the formed terpolymer wherein monomer a) will exceed the molar amount of component b) incorporated into the terpolymer by at least 10 molar% and an effective amount of a surfactant for improving cleaning performance.
