Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a flavor improving agent which alleviates the chemical sensation of a synthetic fragrance and improves the natural, mild and floral sensations. [0002] A compounded fragrance is generally a composition of a natural fragrance and a synthetic fragrance. However, natural fragrances (especially, frequently used floral type) are produced in a small amount and are expensive. difficult. For this reason, synthetic fragrances are generally created mainly, but there is a chemical feeling peculiar to synthetic fragrances. In order to correct this, it is usual to reconsider the combination of fragrance materials, but this method is time-consuming and troublesome. [0003] Accordingly, an object of the present invention is to provide a flavor improving agent which can alleviate the chemical sensation which is a disadvantage of synthetic fragrances. The inventors of the present invention have studied the effects of adding various compounds to compounded fragrances including synthetic fragrances, and have obtained the following formulas (1), (2) and (3). When used in combination, the chemical flavor of the synthetic fragrance is alleviated, and the natural fragrance of the compounded fragrance is not reduced, but rather imparts a natural feeling, a mild feeling, a floral feeling, sustains them, and is refreshing. The present inventors have found that it gives a clear residual scent and completed the present invention. That is, the present invention provides the following component (A):
(B) and (C); (A) the following formula (1): [Wherein R ¹ , R ² and R ³ represent a hydrogen atom, a hydroxy group or an alkyl, alkenyl or alkoxy group having 1 to 10 carbon atoms, and R ⁴ represents a straight or branched chain having 1 to 10 carbon atoms. And (B) an alkylene group or alkenylene group in the chain. (B) The following formula (2): Wherein R ⁵ , R ⁶ and R ⁷ are a hydrogen atom or an alkyl or alkenyl group having 1 to 4 carbon atoms;
^{And 8} represents a linear or branched alkylene group or alkenylene group having 1 to 20 carbon atoms, and m represents an integer of 0 to 4]. (C) The following formula (3): ] Wherein R ⁹ represents an alkyl or alkenyl group having 1 to 8 carbon atoms, wherein R ⁹ represents an alkyl or alkenyl group having 1 to 8 carbon atoms. DETAILED DESCRIPTION OF THE INVENTION In the above formulas (1) and (2),
As the halogen atom represented by R ¹ , R ² , R ³ , R ⁵ , R ⁶ and R ⁷ , a chlorine atom or a bromine atom is preferable.
Further, as the alkyl, alkenyl or alkoxy group having 1 to 10 carbon atoms represented by R ¹ , R ² and R ³ , an alkyl group or an alkoxy group having 1 to 6 carbon atoms is more preferable, and a methyl group or a methoxy group is particularly preferable. preferable. R ⁵ , R
^As the alkyl, alkenyl or alkoxy group having 1 to 4 carbon atoms represented by ⁶ and R ⁷ , a methyl group or a methoxy group is preferable. 1 to 20 carbon atoms represented by R ⁴ and R ⁸
As the linear or branched alkylene, alkenylene or alkynylene group, is preferably a linear or branched alkylene having 1 to 20 carbon atoms or a linear or branched alkenylene group having 2 to 20 carbon atoms. In the formula (3), R ⁹ is preferably an alkyl or alkenyl group having 2 to 7 carbon atoms. Specific examples of the compound of the formula (1) include benzyl alcohol, p-methylbenzyl alcohol, β-
Phenylethyl alcohol, γ-phenylpropyl alcohol, cinnamic alcohol, α-amyl cinnamic alcohol, anis alcohol (p-methoxybenzyl alcohol), δ-phenylbutyl alcohol, ε
-Phenylpentyl alcohol, dimethylbenzylcarbinol, dimethylphenylcarbinol, β-phenyldimethylcarbinol, β-phenylethylmethylethylcarbinol and the like. Specific examples of the compound of the formula (2) include phenoxymethyl alcohol, phenoxyethyl alcohol, 2-benzyloxyethanol, phenoxypropyl alcohol, phenoxybutyl alcohol,
Phenoxypentyl alcohol and the like. Specific examples of the compound of the formula (3) include methyl jasmonate and methyl dihydrojasmonate. In the flavor improving agent of the present invention, these components (A), (B) and (C) may be used alone or in combination of two or more. In addition, the component (A) in the flavor improving agent,
Although the mixing ratio of (B) and (C) is not particularly limited, the total amount of components (A) and (B) is 50% by weight in the flavor improving agent.
(Hereinafter simply indicated by%), preferably 70% or more. [(A) + (B)] :( C) is 1: 1 by weight.
~ 20: 1, particularly preferably 3: 1 to 10: 1. The compounding amount of the flavor improving agent of the present invention to the compounded flavor is 5 to 70%, especially 30 from the viewpoint of the effect of reducing the chemical sensation.
~ 50% is preferred. By using the flavor improving agent of the present invention, the chemical sensation of the synthetic fragrance is alleviated, a natural sensation, a mild sensation and a floral sensation are imparted and sustained,
A blended fragrance having a refreshing scent is obtained. Therefore, the flavor improving agent of the present invention is preferably used for a floral-based compounded fragrance, and can be used for various cosmetics incorporating such compounded fragrance. Examples 1 to 4 Perfume compositions of Comparative Examples and Examples 1 to 4 were prepared according to the formulations shown in Table 1. The evaluation method and evaluation points are as follows. Comparative Example 1 below on a 0.5 cm long, 15 cm wide odor paper
And, in the sensory evaluation room at a temperature of 25 ° C. and a humidity of 65%, 10 expert panelists (five men and women) were applied with the fragrances shown in Examples 1 to 4 1.5 cm (weight: about 0.05 g) from the tip. Immediately after, 2 hours, 4 hours, 8 hours, 12 hours,
The quality of the fragrance after 24 hours was evaluated, and the evaluation was comprehensively made according to the following criteria. ◎: Natural feeling, mild feeling, and floral feeling are sufficiently imparted and are very long-lasting. ：: A natural feeling, a mild feeling, and a floral feeling are imparted and maintained. Δ: Natural feeling, mild feeling, and floral feeling are not given much and the duration is not so much. X: Neither a natural feeling, a mild feeling nor a floral feeling is imparted nor sustained. [Table 1] * 1) Compounded fragrance 1 Bergamot oil 10 Lilyal 15 Lillal 14 Geraniol 8 Benzyl acetate 12 Methylionone 8 Heliotropin 2 Vanillin 1 Benzyl salicylate 30 Total 100 (parts by weight) From Table 1, the components (A), (B) and (C)
It can be seen that the compounded fragrance containing the compound has a reduced chemical feeling, imparts a natural feeling, a mild feeling, a floral feeling, and lasts as compared with the case where these are not added.
