Abstract
The present invention provides a water-soluble or water-dispersible polymers. The water -soluble or water-dispersible polymer comprise a first monomer having hydrogen bonding/complexing properties to polyphenols, a second monomer having detergent properties, and a third monomer having hydrogen bonding/complexing properties to polyphenols, wherein the first monomer and the third monomer are the same or different. The present invention also provides oral care compositions comprising the water-soluble or water-dispersible polymers. The present invention also provides methods of cleaning, Whitening arid polishing natural teeth and dental prosthesis and of preventing, reducing or removing surface deposited stains from teeth by administering the oral care compositions. The water-soluble or water-dispersible polymer has a structure:wherein x, y, z, mole %, n, R1, and R2 are defined herein.
