ORAL CARE COMPOSITIONS CONTAINING BIVALENT TIN SALT, AND METHODS Russian patent published in 2010 - IPC A61K8/19 A61K8/21 A61K8/24 A61Q11/00 

FIELD: medicine.

SUBSTANCE: invention refers to oral care compositions containing bivalent tin salt and sodium tripolyphosphate. The oral care composition contains two phases. The first phase contains approximately 0.01 to approximately 5 wt % of bivalent tin salt in the first orally applicable carrier. The second phase contains approximately 0.01 to approximately 15 wt % of sodium tripolyphosphate and approximately 0.1 to approximately 15 wt % of copolymer of methylvinyl ester and maleic anhydride in the second orally applicable carrier. Total water concentration in the oral care composition is less than approximately 10 wt %. For higher effectiveness, there can be added tetrasodium pyrophosphate and/or a silicon polishing agent for oral application. Immediately before application, two phases are mixed, particularly with using a two-chamber tube wherein the phases are kept in physically divided chambers.

EFFECT: composition is effective in controlling dental deposit and teeth decolouration, thereby maintains stability for a long time.
