Abstract: The present invention relates to oral care compositions comprising stannous ions, a mint-type flavor oil, a protectant component that prevents generation of off odor and off taste in the composition, and orally acceptable carriers. The mint-type oils include peppermint, spearmint and corn mint. Suitable protectant components include copper salts and carbonyl compounds such as ascorbic acid; cis-jasmone; 2,5-dimethyl-4-hydroxy-3(2H)-furanone; 5-ethyl-3-hydroxy-4-methyl-2(5H)-furanone; vanillin; ethyl vanillin; anisaldehyde; 3,4-methylenedioxybenzaldehyde; 3,4-dimethoxybenzaldehyde; 4-hydroxybenzaldehyde; 2-methyoxybenzaldehyde; 4-methoxybenzaldehyde; benzaldehyde; cinnamaldehyde (3-phenyl-2-propenal); hexyl cinnamaldehyde; ?-methyl cinnamaldehyde; ortho-methoxy cinnamaldehyde; ?-amyl cinnamaldehyde; and combinations thereof. The oral care composition may be a dentifrice.

Abstract: The present invention relates to peroxide containing oral care compositions containing a flavor system that effectively masks the undesirable taste and sensations due to peroxide. The flavor system comprises menthol, at least one other secondary coolant and selected flavor chemicals that together provide a stable flavor profile and a high impact refreshing taste and sensation. The secondary coolant is selected from carboxamides, ketals, diols, menthyl esters and mixtures thereof.
