Oral care compositions having improved consumer aesthetics and taste

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.

Description

Claims

1. An oral care composition (a) from about 0.01% to about 30% by weight of the composition of a peroxide source,(b) a flavor composition comprising a coolant combination of menthol and at least one secondary coolant and one or a mixture of flavor components that maintain a consistent flavor profile in the presence of peroxide, and(c) an orally-acceptable carrier,

2. An oral care composition according to claim 1 wherein the peroxide source is selected from the group consisting peroxides, perborates, percarbonates, peroxyacids, persulfates, and mixtures thereof.

3. An oral care composition according to claim 1 wherein the peroxide source is selected from the group consisting of hydrogen peroxide, urea peroxide, calcium peroxide, sodium percarbonate, and mixtures thereof.

4. An oral care composition according to claim 1 comprising a total amount of menthol and secondary coolant of from about 0.03% to about 1.5% by weight of the composition, wherein menthol comprises at least about 0.015% by weight of the composition.

5. An oral care composition according to claim 1 wherein the secondary coolant is selected from carboxamides, ketals, diols, menthyl esters and mixtures thereof.

6. An aqueous oral care composition according to claim 1, further comprising an antimicrobial active selected from cetyl pyridinium chloride, domiphen bromide, zinc salts, stannous salts, chlorhexidine, triclosan, triclosan monophosphate and mixtures thereof.

7. An oral care composition according to claim 1 in the form of a dentifrice or mouthrinse.

8. An oral care composition (a) from about 0.01% to about 10% by weight of the composition of a peroxide source selected from hydrogen peroxide or urea peroxide,(b) from about 0.03% to about 0.6% by weight of the composition of a coolant combination of menthol and at least one secondary coolant, wherein menthol comprises at least about 0.015% by weight of the composition(c) one or a mixture of flavor components selected from methyl salicylate, ethyl salicylate, methyl cinnamate, ethyl cinnamate, butyl cinnamate, ethyl butyrate, ethyl acetate, methyl anthranilate, iso-amyl acetate, iso-amyl butyrate, allyl caproate, eugenol, eucalyptol, thymol, cinnamic alcohol, cinnamic aldehyde, octanol, octanal, decanol, decanal, phenylethyl alcohol, benzyl alcohol, benzaldehyde, alpha-terpineol, linalool, limonene, citral, vanillin, ethyl vanillin, propenyl guaethol, maltol, ethyl maltol, heliotropin, anethole, dihydroanethole, carvone, oxanone, menthone, p-damascenone, ionone, gamma decalactone, gamma nonalactone, gamma undecalactone, and 4-hydroxy-2,5-dimethyl-3(2H)-furanone, and(d) an orally-acceptable aqueous carrier,

9. An aqueous oral care composition according to claim 8 wherein the secondary coolant is selected from carboxamides, ketals, diols, menthyl esters and mixtures thereof.

10. An aqueous oral care composition according to claim 8, further comprising an antimicrobial active selected from cetyl pyridinium chloride, domiphen bromide, zinc salts, stannous salts, chlorhexidine, triclosan, triclosan monophosphate and mixtures thereof.
