Date Aug. 10, 1995Microcapsules based on crosslinked plant polyphenols are described. These microcapsules are obtained by the interfacial crosslinking of plant polyphenols, particularly flavonoids. When incorporated in a composition such as a cosmetic, pharmaceutical, dietetic or food composition, these microcapsules make it possible to prevent any impairment of this composition, in particular any color modification, while at the same time preserving the activity, especially the anti-free radical and/or antioxidizing activity, of the plant polyphenols, particularly the flavonoids.
