Abstract

The present invention primarily concerns teeth cleaning compounds containing menthol for use with a toothbrush, preferably tooth pastes, tooth crèmes, tooth cleaning gels or tooth powders. Such a tooth cleaning compound according to the invention contains menthol and a quantity, for masking the bitterness of the menthol, of menthane carboxylic acid-N-(4-methoxyphenyl)-amide (WS-12) of the following formula (Ia), in particular of the following formula (Ib), i.e. L-menthane carboxylic acid-N-(4-methoxyphenyl)-amide.

The present invention also concerns the use of menthane carboxylic acid-N-(4-methoxyphenyl)-amide (WS-12) of the formulas (Ia) or (preferably) (Ib) to mask the bitter taste of menthol in a teeth cleaning compound.
The present invention also concerns a method for dissolving menthane carboxylic acid-N-(4-methoxyphenyl)-amide (WS-12) in a teeth cleaning compound and a method for masking the bitterness of menthol in a teeth cleaning compound.

First claim

The invention claimed is:

1. A flavoring agent composition, wherein the flavoring agent composition comprises:
(a) menthol;
(b) a quantity of menthane carboxylic acid-N-(4-methoxyphenyl)-amide (WS-12) sufficient to mask the bitterness of the menthol; and
(c) a quantity of menthone sufficient to solubilize the menthane carboxylic acid-N-(4-methoxyphenyl)-amide (WS-12) so that it masks the bitterness of the menthol without the need for further flavoring agents having a log-K ow value in a range of 1.5-5.

2. A finished product comprising the flavoring agent composition of claim 1 , wherein the finished product is selected from the group consisting of a toothpaste, a tooth crème, a tooth cleaning gel, a tooth powder, a mouthwash or mouthwash concentrate, a tooth crème and mouthwash 2-in-1 product, a chewing gum, a hardboiled candy, an instant drink powder, and a gelatin capsule.

3. The finished product according to claim 2 , wherein the finished product is a toothpaste, a tooth crème, a tooth cleaning gel, or a tooth powder, and wherein the finished product further comprises cleaning granules.

4. The finished product according to claim 3 further comprising:
(a) 0-10 wt. % of a chewing gum base, in relation to an overall weight of the finished product; and/or
(b) at least one elastomer in an overall quantity of 0-20 wt. %, in relation to the overall weight of the finished product.

5. The finished product according to claim 3 further comprising:
sugar substitutes;
humectants;
thickening agents;
at least one surfactant;
at least one antimicrobial agent;
at least one coloring;
at least one anticaries agent; and/or
at least one further physiological cooling agent, and
wherein the finished product is free from saccharose, glucose and fructose.

6. The finished product according to claim 3 , wherein a weight ratio of menthane carboxylic acid-N-(4-methoxyphenyl)-amide (WS-12) to menthol is in a range of 1:5-1:1000.

7. The finished product according to claim 6 , wherein the weight ratio of menthane carboxylic acid-N-(4-methoxyphenyl)-amide (WS-12) to an overall quantity, by weight, of menthone is in a range of 1:10-1:200.

8. The finished product according to claim 3 , wherein an overall proportion of menthane carboxylic acid-N-(4-methoxyphenyl)-amide (WS-12) is in a range of 0.00015 -0.26 wt. % in relation to an overall weight of the finished product.

9. The finished product according to claim 3 , wherein the flavoring agent composition comprises:
a) 0.15-1.3 wt. % menthol;
b) 0.00015-0.26 wt. % menthane carboxylic acid-N-(4-methoxyphenyl)-amide (WS-12), wherein a weight ratio of menthane carboxylic acid-N-(4-methoxyphenyl)-amide (WS-12) to menthol is in a range of 1:5-1:1000; and
c) menthone, wherein the weight ratio of menthane carboxylic acid-N-(4-methoxyphenyl)-amide (WS-12) to menthone, is a maximum of 1:10,
wherein the wt. % refers to an overall weight of the finished product.

10. A method for masking the bitterness of menthol in a finished product according to claim 3 comprising mixing:
a) menthol,
b) a quantity of menthane carboxylic acid-N-(4-methoxyphenyl)-amide (WS-12), wherein the quantity of menthane carboxylic acid-N-(4-methoxyphenyl)-amide masks the bitterness of the menthol,
c) menthone in an amount such that the solubility of the menthane carboxylic acid-N-(4-methoxyphenyl)-amide (WS-12) is increased, and
d) at least one further teeth cleaning component.

11. The finished product according to claim 2 , wherein the finished product is a hardboiled candy.

12. The finished product according to claim 11 , wherein the hardboiled candy is sugar-free, and further comprises a sugar substitute selected from the group consisting of isomaltitol (E 953), lactitol (E 966), maltitol, mannitol (E 421), sorbitol (E 420), xylitol (E 967), and mixtures thereof, and/or further comprises an artificial sweetener selected from the group consisting of acesulfame-K, aspartame, cyclamate, a cyclamate salt, neohesperidine dihydrochalcone, sucralose, a sucralose salt, saccharin, and a saccharin salt.

13. The finished product according to claim 11 , further comprising a pellitorine solution, wherein the pellitorine solution comprises pellitorine, propylene glycol, and natural peppermint oil.

14. The finished product according to claim 2 , wherein the finished product is a chewing gum that further comprises a gum base, and optionally comprises an emulsifier selected from the group consisting of sodium lauryl sulfate, sodium lauryl sarcosinate and cocamidopropyl betaine.

15. The finished product according to claim 14 , wherein the chewing gum is sugar-free and further comprises a sugar substitute selected from the group consisting of isomaltitol (E 953), lactitol (E 966), maltitol, mannitol (E 421), sorbitol (E 420), xylitol (E 967) and mixtures thereof, and/or further comprises an artificial sweetener selected from the group consisting of alitame, neotame, thaumatin, acesulfame-K, aspartame, cyclamate, a cyclamate salt, neohesperidine dihydrochalcone, sucralose, a sucralose salt, saccharin, and a saccharin salt.
