Cleaning compositions which enhance hard surfaces to exhibit excellent
water-spreading and oil-repellency and therefore provide a "next time
easier cleaning" consumer benefit contain selected copolymers capable of
forming invisible, extremely thin hydrophilic films on treated surfaces.
The cleaning compositions feature a water-soluble or water-dispersible
copolymer having a first monomer capable of forming a cationic charge on
protonation and a second monomer that is acidic and that is capable of
forming an anionic charge in the compositions, and may contain an
optional third monomer having an uncharged hydrophilic group and/or an
optional fourth monomer that is hydrophobic. The cleaning compositions
may further contain functional ingredients including surfactants, organic
solvents and/or other optional adjuvants to enhance the cleaning
performance and aid in preparation of the surface for effective delivery
of the copolymer during a cleaning operation.
