JP2000247859A - Perfume composition for oral cavity - Google Patents

Abstract

PROBLEM TO BE SOLVED: To obtain the subject composition which is free from the deterioration of palatability due to the odor of a solvent, can improve the refrigerant of 1-menthol and can reinforce the smell and taste of the perfume itself by adding the 1-menthol and a specific ester compound. SOLUTION: This perfume composition for oral cavities comprises (A) 1-menthol preferably in an amount of 30-80 wt.% based on the total amount of the composition, (B) one or more compounds selected from a compound of the formula: R1COOR2 and compounds of formulas I, II and III (R1 is H, a 1-10C alkyl or the like; R2 is a 1-6C alkyl or an alkenyl; R3 to R5 are each a 1-10C hydrocarbon) (for example, methyl formate or methyl benzoate), and preferably further (C) ethanol. The components A and B are preferably compounded in a weight ratio of 1:0.002 to 1:0.1. The perfume composition for oral cavities may preferably be added to compositions for oral cavities. The compositions for oral cavities include oral cavity cosmetics such as dentifrice, oral refrigerants, and mouthwashes, foods such as chewing gums, candies and troches, oral medicines, and the like.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an oral fragrance composition which enhances the refreshing feeling of l-menthol and has excellent palatability.

[0002]

2. Description of the Related Art 1-menthol is added to oral compositions such as toothpaste, mouth freshener, mouthwash and the like to give a refreshing feeling. However, when l-menthol is added in a large amount in order to further enhance the refreshing sensation or improve the expression,
On the contrary, it causes bitterness and irritation. For this reason, a fragrance composition in which ketones are blended with 1-menthol has been proposed (Japanese Patent Application Laid-Open No. 8-157762). However, when ketones are blended with the oral flavor composition, the refreshing sensation and diffusibility are improved, but there is a problem that the taste of the ketones reduces the palatability due to the solvent odor.

[0003]

SUMMARY OF THE INVENTION An object of the present invention is to provide a perfume composition for the oral cavity which does not reduce the palatability due to solvent odor, further improves the refreshing feeling of l-menthol, and enhances the aroma and taste of the perfume itself. To provide things.

[0004]

Means for Solving the Problems The present inventor has found that a combination of l-menthol and a specific ester can provide a perfume composition for the oral cavity having no solvent odor and having a more improved refreshing feeling. .

The present invention relates to l-menthol and the following general formulas (1) to (4):

[0006]

(Wherein R ¹ is a hydrogen atom or a C ¹ -C 1)
Represents an alkyl or alkenyl group of 0, R ² is an alkyl or alkenyl group having 1 to 6 carbon atoms, R ^3, R
⁴ and R ⁵ represent a hydrocarbon group having 1 to 10 carbon atoms), and an oral fragrance composition containing at least one compound represented by formula (I), and an oral composition containing the same. is there.

[0008]

BEST MODE FOR CARRYING OUT THE INVENTION The l-menthol used in the present invention may be isolated from an essential oil of a plant or the like, may be chemically synthesized, or may be an essential oil such as a mint oil containing l-menthol. May be used as it is. Examples of mint oil include Japanese pepper oil, peppermint oil, and the like.
One or more kinds may be used, and may be used in combination with the above-mentioned isolated or synthetic l-menthol.

The amount of l-menthol is not particularly limited, and is preferably 0.01 to 90% by weight, particularly preferably 30 to 80% by weight in the oral flavor composition, since a sufficient refreshing feeling can be obtained.

In the present invention, in the general formula (1), R ¹ is preferably a hydrogen atom or a linear or branched alkyl group having 1 to 6 carbon atoms, and R ² is preferably a linear or branched alkyl group having 1 to 6 carbon atoms. Linear or branched alkyl groups are preferred. Esters number of 7 or more carbon atoms with a carbon number of 11 or greater, or R ² of R ¹ are greasy, palatability decreases.

In general formulas (2) to (4), R ³ , R
Examples of ⁴ and R ⁵ include an alkyl or alkenyl group having 1 to 10 carbon atoms, an aralkyl group having 7 to 10 carbon atoms, and a linear or branched alkyl group having 1 to 6 carbon atoms, a benzyl group, and a phenethyl group. Is preferred.

The compounds represented by the general formulas (1) to (4) include methyl formate, ethyl formate, butyl formate, ethyl acetate, propyl propionate, ethyl butyrate, methyl isobutyrate, isoamyl isobutyrate, butyl valerate , Isobutyl valerate, methyl isovalerate, ethyl hexanoate, propyl hexanoate, hexyl hexanoate, methyl benzoate,
Preferred are ethyl benzoate, isobutyl benzoate, methyl cinnamate, ethyl cinnamate, benzyl cinnamate, methyl salicylate, ethyl salicylate, isobutyl salicylate, isoamyl salicylate.

One or more compounds represented by the general formulas (1) to (4) can be used, and the compounding amount thereof is not particularly limited.
The compounding weight ratio with one or more of the compounds represented by (4) is 1: 0.001 to 1: 0.2, particularly 1: 0.002.
A ratio of 1: 0.1 is preferable since a sufficient cooling effect can be obtained.

The oral flavor composition of the present invention can further contain ethanol, and is preferably an ethanol solution containing the above essential components. This solution may further contain other ingredients used in ordinary oral flavor compositions. Essential oils and fragrances can be blended.

In the present invention, the oral composition is obtained by blending the above-mentioned oral flavor composition. Examples of the oral composition include oral cosmetics such as dentifrices, mouth fresheners, mouthwashes; foods and oral pharmaceuticals used in the oral cavity such as chewing gums, candies and troches to impart a refreshing feeling; .

[0016]

The oral fragrance composition of the present invention has no solvent odor, is excellent in palatability, and can further enhance the refreshing feeling of l-menthol. For this reason, it is useful for cosmetics, foods, pharmaceuticals, etc. that are used in the oral cavity and give a refreshing feeling.
