PEROXYDONE K-30 complex by Ashland Specialty Chemical acts as a whitening agent. It is a highly stable, solid complex of hydrogen peroxide with pharmaceutical-grade polyvinylpyrrolidone. It is stable in a wide range of solvents and provide excellent substantivity, bioadhesion, film-forming and formulation thickening. It releases hydrogen peroxide on contact with water or saliva, resulting in brighter and whiter teeth.

POLYSURF 67 cetyl hydroxyethylcellulose by Ashland Specialty Chemical acts as a thickener, binder, stabilizer, film-former, and as a suspension agent. It is a nonionic water-soluble polymer that contains both hydroxyethyl and long-chain alkyl groups. It is known to associate with the hydrophobic groups of surfactants and other formulation ingredients.

POLYPLASDONE™ XL by Ashland Specialty Chemical acts as a rheology modifier and tablet disintegrant. It is a non-ionic, water-insoluble but swellable crosslinked PVP homopolymer. Due to porous particle morphology, it acts as super disintegrants, providing rapid disintegration to denture-cleaning tablets.

PLASDON K29/32 polymer by Ashland Specialty Chemical acts as a rheology modifier. It is a stable, water-soluble polyvinylpyrrolidone that meets U.S., European and Japanese pharmacopoeia specifications for Povidone. It forms complexes with catechins, just as it does with many other compounds that cause discoloration of teeth. The polymer can be effectively used to bind and remove stains through hydrogen bonding with chemical compounds.
