Oral care compositions with improved flavor
Oral care compositions having improved taste, said compositions comprising: a carrier material; from about 0.001 to about 10%, by weight of the composition, of an oral care component selected from metal salts, antimicrobial agents, bad breath reduction agents, bleaching agents, surfactants, or a combination thereof; and from about 0.0001 to about 1%, by weight of the composition, of a TRPA1 agonist selected from vanillin esters; benzoate esters; hydroxybenzoate derivatives; methoxy benzoate derivatives; hydroxybutanedioate derivatives; benzamidobenzoate derivatives; methylpropanoate derivatives; phenyl acetate derivatives; hex-3-enoate derivatives; 2-(furan-2-ylmethylsulfanyl)-3-methylpyrazine; phenylmethoxymethylbenzene; (2R)-2-azaniumyl-3-[(2R)-2-azaniumyl-3-oxido-3-oxopropyl]disulfanylpropanoate; (3E)-2-hydroxy-4,8-dimethylnona-3,7-dienal; (2R)-2-azaniumyl-3-[(2S)-2-azaniumyl-3-oxido-3-oxopropyl]disulfanylpropanoate; (3Z)-3-butylidene-2-benzofuran-1-one; 3-methyl-N-(3-methylbutyl)butan-1-imine; 2-(furan-2-ylmethyldisulfanylmethyl)furan; and combinations thereof. Uses thereof and methods of improving the taste of an oral care composition.
1. An oral care composition having improved taste comprising:
a. from about 0.05% to about 11% of a metal composition selected from the group consisting of zinc and salts thereof;
b. from about 0.0001% to about 0.02% TRPA1 agonist wherein the TRPA1 agonist is vanillin isobutyrate; and
c. from about 0.0001% to about 0.02% warming sensate wherein the warming sensate is vanillyl butyl ether;
wherein the vanillin isobutyrate and the vanillyl butyl ether reduce a bitter character in the oral care composition;
and wherein the composition has at most a slight vanilla character.
2. An oral care composition according to claim 1 further comprising a stannous salt selected from the group consisting of stannous fluoride, stannous chloride, stannous iodide, stannous chlorofluoride, stannous actetate, stannous hexafluorozirconate, stannous sulfate, stannous lactate, stannous tartrate, stannous gluconate, stannous citrate, stannous malate, stannous glycinate, stannous pyrophosphate, stannous metaphosphate, stannous oxalate, stannous phosphate, stannous carbonate, and combinations thereof.
3. An oral care composition according to claim 1 wherein the composition further comprises a sweetener selected from sucralose, REBIANA, NHDC, acesulfame K, or a combination thereof.
4. An oral care composition according to claim 1 wherein the composition further comprises from about 0.01% to about 30% of an abrasive.
5. An oral care composition according to claim 1 wherein the composition comprises vanillin isobutyrate and vanillyl butyl ether in about a 1:1 ratio.
6. The oral care composition of claim 1 wherein the composition comprises from about 0.0001% to about 0.01%, by weight of the composition, of the vanillin isobutyrate and from about 0.0001% to about 0.01%, by weight of the composition, of the vanillyl butyl ether.
7. The oral care composition of claim 1 wherein the composition comprises less vanillyl butyl ether than vanillin isobutyrate, by weight.
8. The oral care composition of claim 1 wherein the composition comprises from about 0.05% to about 5%, by weight, of the metal composition.
9. The oral care composition of claim 8 wherein the metal salt comprises zinc citrate.
10. The oral care composition of claim 8 wherein the metal salt comprises zinc lactate.
11. The oral care composition of claim 1 further comprising sodium citrate.
12. The oral care composition of claim 1 further comprising stannous chloride.
13. The oral care composition of claim 1 further comprising hydrated silica.
14. The oral care composition of claim 1 further comprising sodium saccharin.
