Plasdone™ K-29/32 polymer INCI Name: PVP
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.
Research has demonstrated that toothpaste, mouthwash and oral rinse formulations show improved stain removal with the addition of Plasdone K-29/32 polymer up to 2 percent.
Typically used in wet granulation processes, Plasdone K-29/32 polymer is an exceptional tablet binder providing high tablet-breaking force and low friability to denture cleaning tablets.
- Rheology modification
- Whitener and stain removal
- Excellent tablet binders
