A dual component tooth whitening composition is disclosed, which composition contains a peroxide whitening and a second ingredient incompatible with the peroxide compound such as a nonionic antibacterial agent, the second ingredient and the peroxide compound each being incorporated in separate dentrifice components which are physically separated until dispensed for use, the components retaining their original physical state when in contact, the first component being a composition containing a peroxide whitening compound in a vehicle thickened with a combination of a particulated water insoluble inorganic compound such as for example a inorganic compound such as fumed silica or Laponite and an organic thickener other than an alkylene oxide polymer such as for example a carboxyl vinyl polymer, and the second component containing the ingredient incompatible with the peroxide.
L'invention porte sur une composition blanchissant les dents à deux composants contenant un peroxyde de blanchiment, et un deuxième ingrédient incompatible avec le peroxyde tel qu'un antibactérien non ionique. Les deux constituants, incorporés à des compositions de dentifrice distinctes, et séparées jusqu'à leur utilisation conservent leur état physique original lorsqu'ils sont mis en contact. Le premier constituant consiste en un peroxyde de blanchiment dans un véhicule, épaissi par une combinaison d'un composé minéral particulaire par exemple de silice sublimée ou de Laponite et d'un épaississeur organique autre qu'un polymère d'oxyde d'alkylène, tel que par exemple un polymère de carboxylvinyle, le deuxième composant contenant l'ingrédient incompatible avec le peroxyde.
