COMPOSITION FOR DENTAL BLEACHING

摘要

This invention relates to a bleaching composition for the bleaching of discoloured teeth, whereby the bleaching composition contains an activatable peroxide compound and a TiO2 photocatalyst with an average particle size of maximum 300 nm for photocatalytic decomposition of the peroxide and the release of free radicals capable of reacting with the discolouring substances present in the teeth, characterised in that the TiO2 present in the composition is doped with S and the TiO2 particles have an average particle size of < 100 nm.
