Description

Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION This invention relates to low alcohol perfume compositions, and in particular to improvements in their solvent compositions.

[0002]

2. Description of the Related Art Generally, a fragrance is rarely used alone, and is often used by diluting it with a fragrance solvent containing ethyl alcohol as a main component. On the other hand, in recent years, interest in environmental issues has increased, and regulations on volatile organic compounds are planned in the United States. Ethyl alcohol, which is an organic solvent, has been pointed out as a kind of this volatile organic compound. For alcoholic fragrance compositions containing 20% by weight or less of a fragrance, the amount of volatile organic compounds such as ethyl alcohol is 75% by weight or less. It is required to gradually decrease until.

[0003]

However, for example, in the case of a product with a fragrance of 15% by weight or less, if the ethyl alcohol content is 75% by weight or less, the remaining amount of about 10% by weight or more must be supplemented with another solvent. However, since the solvent dissolves ethyl alcohol or a fragrance well and is used by being applied to the skin, it is required to be non-toxic, less sticky, and easy to dry. It was extremely difficult to adopt a low-volatile organic solvent that complies with the regulations concerning. In addition, it was extremely difficult to contain 10% by weight or more of water having no flash point in the formulation without using an activator.

The present invention has been made in view of the above-mentioned problems of the prior art, and an object thereof is to reduce the amount of ethyl alcohol used, and to reduce the solubility of a fragrance and the usability of a fragrance composition as a low alcohol. To provide a fragrance composition.

[0005]

Means for Solving the Problems As a result of intensive studies made by the present inventors in order to achieve the above-mentioned object, in a low alcohol perfume composition containing 20% by weight or less of perfume ingredients and 75% by weight or less of ethyl alcohol, other It has been found that excellent usability can be maintained by using lower alcohol and water as the main components of the solvent component for perfume, and the present invention has been completed. That is, the low alcohol perfume composition according to claim 1 of the present application is characterized in that the lower alcohol is 10% by weight or more, the ethyl alcohol is 75% by weight or less, the water is 40% by weight or less, and the perfume component is 20% by weight or less. And It is preferable that the content of ethyl alcohol is 10 to 75% by weight and the content of lower alcohol: water is 2: 3 to 4: 1.

The lower alcohol is 3-methyl-3-
It is preferable that it is composed of methoxybutanol, and the amount ratio of lower alcohol to water is in the dissolution region of the phase diagram shown in FIG.
According to the regulation of volatile organic compounds, for example, when the fragrance component is 15% by weight, the amount of solvent is 85% by weight. On the other hand, since the usable amount of ethyl alcohol is 75% by weight or less, 10% by weight or more of the amount of the solvent has to be replaced with a solvent or the like which is not regulated by the volatile organic solvent. On the other hand, since the fragrance composition may be directly applied to the skin, safety is an extremely important requirement.

Therefore, the present inventor has focused on lower alcohols having 4 or more carbon atoms in the main chain, and has 20% by weight or less of a fragrance and 75% by weight or less of ethyl alcohol, and is a very low alcohol which is excellent in usability. The fragrance composition was completed. Conventionally, these lower alcohols are usually blended in cosmetics such as lotions, detergents, and emulsions in an amount of 10% by weight or less, and thus are not used in the low alcohol perfume composition of the present invention. It was a thing.

According to experiments conducted by the present inventor, the lower alcohol having a carbon number of 4 or more in the main chain has a property called amphipathic property which dissolves both the perfume which is an oil component and water. FIG. 1 shows the results of solubility experiments performed by the present inventor using a rose-like fragrance as an example of a fragrance and 3-methyl-3-methoxybutanol (MMB) as an example of a lower alcohol. ing. As is clear from this figure, if the usability is not taken into consideration, the perfume can be dissolved using water and 3-methyl-3-methoxybutanol without using ethyl alcohol. The present inventors have completed the present invention by paying attention to this amphipathic property of lower alcohol compounds. That is, in the low alcohol composition according to claim 1 of the present invention, 40% by weight or less of water is due to the amphipathic nature of the lower alcohol. In addition, since the formulation contains water and lower alcohol, it has a good feeling when used on the skin and also has a moisturizing effect.

[0009]

The present invention will be described in more detail based on the following examples. In addition, the compounding amount is shown by weight% unless otherwise specified.

First, the present inventors have examined lower alcohols as a solvent for diluting perfumes.

[Table 1] ───────────────────────────────── Fragrance 20 20 20 20 20 20 20 Ethyl alcohol 35 35 35 35 35 80 3-Methyl-3-methoxybutanol 30 0 0 45 0 0 3-Methoxy-1-butanol 0 30 0 0 0 0 0 1-Methoxy-2-butanol 0 0 30 0 0 0 Ion-exchanged water 15 15 15 15 0 45 0 ───────────────────────────────── Solubility ◎ ◎ ◎ ◎ × ◎ Quick drying ◎ ◎ ◎ ◎ ◎ − ◎ Stickiness ◎ ◎ ◎ ○ − ◎ Solvent odor ◎ ○ △ ○ − ◎ ──────────────────────────────────

From the above results, when ethyl alcohol is used other than the fragrance, it has excellent solubility and quick-drying property, and has extremely little stickiness. Meanwhile, add 35% ethyl alcohol
%, Ion-exchanged water to 15%, and the other portion is a lower alcohol compound such as 3-methyl-3-methoxybutanol, 3-methoxy-1-butanol, and 1-methoxy-2.
-When either butanol, diacetin (glycerol α, α-diacetate) or 2,2-dimethyl-1,3-propanediol is used, 1-methoxy-2-butanol and diacetin give a odor of the solvent. In addition, other lower alcohol compounds having 4 or more carbon atoms in the main chain have no practical problems. In particular, in the case of 3-methyl-3-methoxybutanol and 3-methoxy-1-butanol, there was no problem in quick-drying and raw material odor.

Next, using 3-methyl-3-methoxybutanol as an example of a lower alcohol having a main chain of 4 or more carbon atoms, investigation was made on the blending of a diluting solvent.

[Table 2] ────────────────────────────────── Perfume 20 20 20 20 20 20 20 20 20 Ethyl alcohol 40 35 30 25 20 15 15 10 5 3-Methyl-3-methoxybutanol 27 30 33 33 37 40 43 47 50 Ion-exchanged water 13 15 15 17 18 20 20 22 23 25 ───────────────── ────────────────── Solubility ◎ ◎ ◎ ◎ ◎ ◎ ◎ ◎ ◎ ◎ Fast drying ◎ ◎ ◎ ◎ ◎ ○ ○ ○ ○ Solvent odor ◎ ◎ ◎ ◎ ○ △ △ △ Sticky ◎ ◎ ◎ ○ ○ ○ △ △ ──────────────────────────────────

The ratio of 3-methyl-3-methoxybutanol to ion-exchanged water was fixed at about 2: 1 and a part of ethyl alcohol was replaced. As a result, 1 part of ethyl alcohol
Even if the amount is reduced to 0%, good use aptitude can be maintained, and particularly preferably, the amount can be replaced up to 20% by weight.

[Table 3] ───────────────────────────────── Perfume 20 20 20 20 20 20 20 20 20 Ethyl alcohol 30 30 30 30 30 30 30 30 30 3-Methyl-3-methoxybutanol 10 15 20 25 30 30 35 40 45 ion-exchanged water 40 35 35 30 25 20 15 15 10 5 ────────────────── ──────────────── Solubility × × ○ ◎ ◎ ◎ ◎ ◎ ◎ Fast-drying − − ◎ ◎ ◎ ◎ ○ ○ Solvent odor − − ◎ ◎ ◎ ◎ ○ △ △ Sticky − − ◎ ◎ ◎ ○ ○ ○ ──────────────────────────────────

As is clear from Table 3 above, the ratio of 3-methyl-3-methoxybutanol to ion-exchanged water is 2:
It is preferably 3 to 4: 1. As described above, the product value and usability can be sufficiently maintained by appropriately adjusting the blending amounts of the lower alcohol, the ion-exchanged water, and the ethyl alcohol.

As a result of the above, in the range where the total amount of the lower alcohol and the ion-exchanged water is 10% by weight or more,
By producing the fragrance composition, it is possible to reduce the amount of ethyl alcohol used while maintaining the usability. A similar tendency is recognized up to about 50% by weight of the fragrance.

[0016]

As described above, according to the low alcohol perfume composition of the present invention, the total amount of the lower alcohol and the ion-exchanged water is 10% by weight or more,
The amount of ethyl alcohol used can be reduced without lowering the usability.
