DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a low alcohol fragrance composition, and more particularly to an improvement in a solvent composition thereof.

[0002]

2. Description of the Related Art In general, a fragrance is rarely used alone, and is often used after being diluted with a fragrance solvent containing ethyl alcohol as a main component. On the other hand, interest in environmental issues has been increasing in recent years, and regulations on volatile organic compounds are scheduled in the United States. Ethyl alcohol which is a solvent for flavoring is also pointed out as one kind of the volatile organic compound. For an alcohol flavoring composition having a flavoring of 20% by weight or less, the amount of volatile organic compound such as ethyl alcohol is reduced to 75% by weight. It is required to reduce it step by step to the following.

[0003]

However, for example, in the case of a product having a fragrance of 15% by weight or less, if the amount of ethyl alcohol is 75% by weight or less, the remaining amount of about 10% by weight must be supplemented with another solvent. However, since the solvent dissolves ethyl alcohol or fragrance well and is used by applying it to the skin, etc., it is required that the solvent be non-toxic, have low stickiness, and be easily dried. It has been extremely difficult to employ low volatile organic solvents that meet the regulations for compounds. The present invention has been made in view of the problems of the related art, and an object of the present invention is to provide a low-alcohol fragrance composition that conforms to the regulation on the volatile organic compound and does not affect the feeling of use. is there.

[0004]

Means for Solving the Problems As a result of diligent studies conducted by the present inventors to achieve the above object, a low alcohol fragrance composition having a fragrance component of not more than 20% by weight and ethyl alcohol of not more than 75% by weight has been disclosed. The present inventors have found that excellent usability can be maintained by using diethylene glycol monoethyl ether or glycerol triacetate as the main component of the perfume solvent component, and completed the present invention. That is, the low alcohol fragrance composition according to claim 1 of the present application is 3% by weight or more of diethylene glycol monoethyl ether, and the total of the diethylene glycol monoethyl ether and glycerol triacetate is 10% by weight or more, and 75% by weight of ethyl alcohol. Hereinafter, the total of other solvent components is 10% by weight or less, and the flavor component is 15% by weight.
% By weight or less.

According to the regulation of volatile organic compounds, when the flavor component is 15% by weight or less, the amount of the solvent is 85% by weight or more. On the other hand, since the usable amount of ethyl alcohol is 75% by weight or less, 10% by weight or more of the fragrance composition must be replaced with another solvent. On the other hand, since the fragrance composition may be applied directly to the skin, safety is a very important requirement. Therefore, the present inventors have focused on a fragrance controlling agent and a fragrance retaining agent which have been conventionally used in a fragrance composition. Thus, a low alcohol fragrance composition having good usability was completed. Conventionally, these perfume modifiers or perfume retaining agents are usually blended in an amount of about 5 to 30% by weight with respect to the perfume. Was 5 to 30% by weight based on 15% by weight of the fragrance, that is, less than 5% based on the total amount of the low alcohol fragrance composition.

As described in, for example, JP-A-59-76011 or JP-A-59-76012,
In the case of expecting a holding or adjusting effect on fragrance,
It is based on the fact that if too much is added to the fragrance, these effects tend to be too strong. On the other hand, the present inventors, when a specific flavoring agent or perfume retention agent is used together with the dilution ethyl alcohol, the function of the perfume conditioning agent or perfume retention agent is appropriate. It has been found that, even if the amount is far greater than the amount of the fragrance, the function as a low alcohol fragrance composition is not impaired.

[0007]

The present invention will be described in more detail with reference to the following examples. In addition, the compounding amount is shown by weight% unless otherwise specified. First, the present inventors studied various retention agents and modifiers as diluting solvents for fragrances.

[Table 1] {Fragrance 10% 10% 10% 10%} ───────────────────────────────────Ethyl alcohol 90% 75% 75% 75% ───── ───────────────────────────────Crycerol triacetate 0% 15% 0% 0% ───────── ─────────────────────────── ethylene glycol monoethyl ether 0% 0% 15% 0% ─────────── ─────────────────────────Triethyl citrate 0% 0% 0% 15% ────────────── ─────────────────── ── Solubility ◎ ◎ ◎ ◎ Quick drying ◎ ○ ○ × Sticky ◎ △ ○ × ─────────────────────────────── ─────

From the above results, when ethyl alcohol is used other than the fragrance, it has excellent solubility and quick-drying properties and has very little stickiness. On the other hand, 75
%, And the other part is changed to diethylene glycol monoethyl ether, although the evaluation on quick-drying and stickiness is slightly lowered, the solubility is good and it is sufficiently practical. Moreover, conventionally, the retention agent is 30% of the fragrance.
When blended above, the balance of the fragrance at the initial stage of application tended to be rather distorted, but by coexisting diethylene glycol monoethyl ether with a large amount of ethyl alcohol, the scent balance was not disrupted from the initial stage of application,
In addition, the function as a retention agent was sufficiently exhibited.

[0009] On the other hand, glycerol triacetate, triethyl citrate and the like do not have any problem in solubility, but cause problems such as stickiness and quick drying, and cannot be used alone as main components. Next, the mixing of diethylene glycol monoethyl ether and other diluting solvents was examined.

[Table 2] ──────────────────────────────────── Fragrance 10% 10% 10% 10% 10 % 10% 10% Diethyl alcohol 75% 75% 75% 75 % 75% 75% 75% Polyethylene glycol monoethyl ether 10% 10 % 10% 10% 5% 3% 1% Quercerol triacetate 5 % 0% 0% 0% 5% 7% 9% ──────────────────────────────────── β -Phenylethyl-2-ethylhexanoe 0% 5% 0% 0% 5% 0% 0% ──────────────────────────────────── Triethyl citrate 0% 0% 5% 0% 0% 5% 5% ───────────────────────────────── ─── Glycerin 0% 0% 0% 5% 0% 0% 5% ──────────────────────────────── ──── Solubility ◎ ◎ ◎ ○ ◎ ◎ ○ Quick drying ○ ○ ○ × ○ ○ △ Sticky ○ ○ △ × ○ △ × ────────────────────明 ら か As is clear from Table 2, when diethylene glycol monoethyl ether was used as the main solvent and another solvent was added, the amount of the other solvent was Is up to 5-10%
Although the usability is slightly reduced, the product value can be maintained. Of these, the combination of diethylene glycol monoethyl ether and glycerol triacetate is particularly compatible, and even if diethylene glycol monoethyl ether is reduced to about 3% by weight and the corresponding amount is replaced by glycerol triacetate, each of them has a great effect on the usability. Absent. On the other hand, the total of diethylene glycol monoethyl ether or glycerol triacetate is 10%.
When the content is less than 10% and the amount of the other solvent exceeds 10%, the usability, particularly the tackiness, becomes remarkable, and the product value tends to decrease.

As a result, as long as the content of diethylene glycol monoethyl ether is 3% by weight or more, the total amount of diethylene glycol monoethyl ether and glycerol triacetate is 10% or more, and the amount of other solvent is 10% or less, By producing the composition, the amount of ethyl alcohol used can be reduced while maintaining the usability. Note that the same tendency is observed in the range of about 3 to 15% of the fragrance, and it has been clarified that it is preferable to use another solvent composition at 20% or more.

[0011]

As described above, according to the low alcohol fragrance composition of the present invention, by mixing 3% by weight or more of diethylene glycol monoethyl ether and 10% by weight or more of the total of glycerol triacetate, The amount of ethyl alcohol used can be reduced without lowering usability.
