Plasdone™ K-29/32 polymer
Chemistry: PVP polymers and copolymers
INCI: PVPSDS Link >
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.
