Plasdone™ k-29/32 polymer is a stable, water-soluble polyvinylpyrrolidone that meets U.S., European and Japanese pharmacopoeia specifications for Povidone. Plasdone™ k-29/32 polymer 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. 

plasdone™ k-29/32 polymer offers the following features and benefits:

  • complexes with common staining agents to whiten teeth
  • reduces in-vitro teeth staining from cationic antibacterial agents
  • acts as a tablet binder


  • toothpastes
  • mouthwashes
  • teeth whiteners

Additional grades of pharmaceutical grade pvp are available.
