Title:
METHOD FOR PREVENTING COLORATION OF CATECHINS AND DENTIFRICE COMPOSITION
Document Type and Number:
WIPO Patent Application WO/2008/010403
Kind Code:
A1
Abstract:
The invention is directed to a method for preventing coloration of catechins by adding to catechins, a water-soluble polymer capable of forming a water-insoluble complex with catechins; and hydrogel particles containing a water-insoluble complex of catechins and a polymer capable of forming a water-insoluble complex with catechins. Further, the invention is directed to a dentifrice composition containing hydrogel particles containing catechins and a polymer capable of forming a water-insoluble complex with catechins, a binder and water.
