CA 2220161

A dental product is provided packaged in a telescopically arranged multi-cavity dispensing container having at least two cylinders in an upper bodythereof. Peroxide and baking soda are placed as active ingredients in separate respective semi-solid streams, each stream being in separate ones of the cylinders. Uniform dispensing of each stream to deliver relatively equivalent ribbon length of each stream by incorporating a synthetic linear anionic polycarboxylate or a polyphosphate to adjust viscosity. Preferred polycarboxylates are homopolymers of acrylic, methacrylic and maleic acids, most especially a copolymer of vinyl methyl ether and maleic acid or anhydride, and preferred polyphosphates are tripolyphosphates, hexametaphosphates and pyrophosphates.

Produit dentaire emballé dans un contenant-distributeur télescopique à multiples cavités, possédant au moins deux cylindres dans une partie supérieure. Du peroxyde et du bicarbonate de sodium sont mis en place séparément dans chacun des cylindres, sous forme de circuits semi-solides d'ingrédients actifs. Chaque circuit permet de distribuer uniformément une longueur relativement équivalente de bande, grâce à l'incorporation d'un polycarboxylate ou d'un polyphosphate, anioniques, linéaires et synthétique, pour ajuster la viscosité. Comme polycarboxylates, on privilégie les homopolymères d'acides acrylique, méthacrylique et maléique, et plus particulièrement un copolymère de méthoxyéthylène et d'acide ou d'anhydride maléique; enfin, comme polyphosphates, on préfère les tripolyphosphates, les hexamétaphosphates et les pyrophosphates.
