Abstract
The present invention relates to oral care compositions with an improved teeth whitening effect. This effect is achieved by inclusion in the oral care compositions of certain organic peroxy compounds as teeth whitening/bleaching agents, particularly peroxyamidophthalamides, sulphoperbenzoic acid, monoperoxyphthalic acid, and (per)acetylatedperboric acid with imine quaternary salts as catalysts for the peroxy compounds.
