ORAL CARE AND ORAL HYGIENE PRODUCTS HAVING PHOTOCATALYTIC ACTIVITY COMPRISING INORGANIC PARTICLES SUPERFICIALLY FUNCTIONALISED WITH TIO2 NANOPARTICLES

摘要

The present invention refers to oral care and oral hygiene products having photocatalytic activity comprising particles of a calcium phosphate compound, superficially functionalised with Ti02 nanoparticles in crystalline form, said Ti02 nanoparticles having: a) a substantially lamellar morphology; b) an aspect ratio (AR) comprised between 5 and 30; c) a surface structure having face (001) as outermost face of the crystalline lattice; and d) wherein the Ti02 is in the form of anatase, optionally mixed with rutile and/or brookite.
