Abstract

PROBLEM TO BE SOLVED: To obtain a perfume compsn. which can be homogeneously dissolved though it has a high terpene content. SOLUTION: This compsn. contains (A) a terpene, (B) an ingredient which is selected from among esters (excluding diethyl phthalate), aldehydes, ketones, lactones, carboxylic acids, acetals, ethers, sulfur-contg. compds., and nitrogen- contg. compds., and is different from ingredient C, (C) a perfume having a log Pow value of 0 or lower, and (D) an alcohol different from ingredient C in such amts. that the wt. ratio of A/B is (85/15)-(100/0); that the content of C is such that it is higher than whichever is the higher between 3 times that of ingredient B and 5 wt.% of the sum of ingredients A and B and that it is not higher than 95 wt.% of the compsn., and that the wt. ratio of D/C is 1/30 or higher.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fragrance composition which contains a large amount of terpenes and can be uniformly dissolved.

[0002]

2. Description of the Related Art A fragrance composition containing a large amount of terpenes used in dishwashing detergents, colognes, and the like requires a flash point adjustment,
Diethyl phthalate has been used for price adjustment, viscosity adjustment, scent adjustment and the like. Diethyl phthalate has good solubility and is suitable, but it has been difficult to use because it has been published by the Environment Agency as an environmental hormone substance.

As alternatives, propylene glycol, diethylene glycol monoethyl ether and the like are preferred from the viewpoint of cost and the like.
The gPow value is 0 or less, and the solubility of terpenes is poor.

[0004]

An object of the present invention is to provide a fragrance composition which contains a large amount of terpenes and can be uniformly dissolved without using diethyl phthalate.

[0005]

Means for Solving the Problems The inventors of the present invention have obtained a fragrance composition which can be uniformly dissolved even if it contains a large amount of terpenes by using a specific amount of alcohol together with a fragrance having a logPow value of 0 or less. Was found to be.

That is, the present invention relates to (A) terpenes,
(B) a fragrance other than component (C) selected from esters, aldehydes, ketones, lactones, carboxylic acids, acetals, ethers, sulfur-containing compounds and nitrogen-containing compounds other than diethyl phthalate, (C) logPow It contains a fragrance having a value of 0 or less and an alcohol other than the (D) component (C), and the weight ratio of the components (A) and (B) is (A):
(B) = 85: 15 to 100: 0, and the content of the component (C) is at least 3 times by weight of the component (B) or at least 5% by weight of the total amount of the components (A) and (B). An object of the present invention is to provide a fragrance composition in which the amount is not more than 95% by weight in the whole composition and the content of the component (D) is 1/30 times by weight or more of the component (C).

[0007]

DETAILED DESCRIPTION OF THE INVENTION The terpenes of the component (A) used in the present invention are not particularly limited as long as they are usually used in a fragrance composition, and examples thereof include limonene, α-pinene, terpinolene and the like. One or more terpenes can be used, and it is effective and preferable to mix 1.8 to 94% by weight, particularly 70 to 94% by weight in the whole composition.

The fragrance of the component (B) is not particularly limited as long as it is generally used in fragrance compositions. Among these, esters other than diethyl phthalate, such as benzyl benzoate and phenoxyethyl Isobutyrate and the like. Aldehydes include, for example, hexylcinnamic aldehyde, hydroxycitronellal and the like; ketones include
Examples include camphor, β-ionone and the like; examples of lactones include γ-undecalactone, cyclopentadecanolide and the like; examples of carboxylic acids include
Examples include benzoic acid, phenylacetic acid and the like; examples of acetals include acetaldehyde, ethylphenylethyl acetal, citral, and diethyl acetal; examples of ethers include rose oxide, 1,8-cineole and the like. Examples of the sulfur-containing compound include p-menthen-8-thiol, dimethylsulfide and the like;
For example, indole, geranyl nitrile and the like can be mentioned.

One or more kinds of fragrances of component (B) can be used, and it is preferable to add 0 to 10% by weight, particularly 0 to 8% by weight in the total composition.

The mixing ratio (weight ratio) of components (A) and (B) is (A) :( B) = 85: 15-100: 0,
Preferably 90:10 to 100: 0, particularly preferably 9
5: 5 to 100: 0.

The fragrance of the component (C) has a logPow value of 0 or less,
Preferably it is a thing of 0-2. Here, the logPow value is a 1-octanol / water partition coefficient of a chemical substance, and is a value obtained by calculation by the f-value method (hydrophobic fragment constant method). Therefore, the logPow value is easily obtained by calculation from the chemical structure of the fragrance substance, and specifically, is obtained by decomposing the fragrance substance into its constituent elements and integrating the hydrophobic fragment constant (f value) of each fragment. Can be

Specific examples of such fragrances include dipropylene glycol, propylene glycol, diethylene glycol monoethyl ether, diethylene glycol monomethyl ether, 3-methyl-1,3-butanediol, 2-methyl-1,3-propanediol, -Methoxy-3-methyl-1-butanol, dipropylene glycol monoethyl ether, dipropylene glycol monomethyl ether, 2-methyl-1,3-propanediol, 1,3-butanediol and the like.

The fragrance of the component (C) is 95% by weight or more of the total amount of the component (C) at least 3 times by weight or 5% by weight or more of the total amount of the components (A) and (B). The amount is not exceeded, preferably 20 to 70% by weight. In addition, one or more kinds of fragrances of the component (C) can be used, and 4.7 to 95% by weight, preferably 4.7 to 23% by weight is preferably blended in the whole composition.

The alcohol of component (D), other than component (C), is not particularly limited as long as it is generally used in a fragrance composition, and may be either an aromatic alcohol or an aliphatic alcohol. Alcohol, phenylethyl alcohol, n-decanol, citronellol, geraniol, linalool and the like can be mentioned. Particularly, terpene alcohols such as citronellol, geraniol, and linalool are preferable.

The alcohols of the component (D) are
1/30 weight times or more, preferably 1/20 weight times or more, particularly preferably 1/10 weight times or more. 1
If it is less than / 30 times by weight, terpenes cannot be uniformly dissolved. One or more alcohols can be used, and 0.16 to 3.2% by weight, particularly 0.16% by weight in the total composition.
０．７0.77% by weight is preferred.

The fragrance composition of the present invention can further contain optional components which are usually added to the fragrance composition, as long as the effects of the present invention are not impaired, and can be produced by a conventional method.

[0017]

The perfume composition of the present invention can be uniformly dissolved without using diethyl phthalate even if it contains a large amount of terpenes. It is suitably used for dishwashing detergent, cologne, shampoo and the like.

[0018]

Example 1 A fragrance composition having the composition shown in Tables 1 and 2 was produced by a conventional method.
The solubility was evaluated. The results are shown in Tables 1 and 2.

(Evaluation method) The state of the fragrance composition was visually observed, and those with smudge or separation were evaluated as "insoluble" and those without smudge were evaluated as "soluble".
