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, R, and Rare defined herein.

Polymers for oral care compositions

In accordance with this invention, there is provided an oral care composition comprising a multimodal blend of copolymers of maleic acid or maleic anhydride and an alkyl vinyl ether and a non-cationic antibacterial agent. The compositions feature improved retention of the antibacterial agent on teeth.

Oral care compositions

A liquid, substantially anhydrous tooth whitener composition for delivery of a tooth-whitening amount of active whitening ingredient onto teeth, with effective bioadhesion and retention thereof, and, thereupon, sufficient penetration of the ingredient through the tooth enamel, providing efficacious bleaching of stained teeth.

Tooth whitening compositions

A delivery system for delivering a tooth whitening substance to a surface of an oral cavity, comprising a film of flexible malleable polymer material having a tooth whitening substance as an integral component of said film, thus providing an active on said oral surface when said film is adhered to the oral surface, said film having a dissolution rate in the aqueous medium of the oral cavity such that the tooth whitening substance can release its active upon said oral surface to act effectively thereon within a predetermined period of time, said film being disintegrable thereafter after effecting its tooth whitening action.
