Description

[Detailed description of the invention] 3. Detailed description of the invention Technical fields> The present invention relates to transparent gel fragrance compositions.

Prior Art and Problems to be Solved by the Invention Conventionally, when sodium stearate is used as a gelling agent for hydrocarbon compounds, it has not been known to use alcohols or glycols in addition to water. was.

For example, JP-A-60-53148, JP-A-55-754
No. 93, Special Publication No. 61-8696, Special Publication No. 57-168
No. 18, JP-A No. 57-125752, diethylene glycol, dipropylene glycol, ethanol, 3-medylene-3-methoxybutanol, cellosolve, methylcarpitol recall, propylene glycol, glycerin, polyethylene glycol, hexylene glycol, 1 , 6-hexanediol, 1.5-bentanediol, 2.2-
Dimethyl-1,3-propanediol and the like are disclosed.

However, when using the alcohols or glycols disclosed above, the resulting fragrance composition does not have transparency, or even though it is initially translucent, it becomes completely opaque over time, making it difficult to consider the aesthetics of transparency. There were some difficulties when doing so.

On the other hand, JP-A-60-85756 discloses a transparent solid fragrance using at least one selected from the group consisting of benzyl alcohol, methylbenzyl alcohol, phenylethyl alcohol, phenylpropyl alcohol, and phenoxyethanol. . However, in order to accomplish this, the amount of the aromatic monohydric alcohol used must be large, from about 10 to about 90% by weight, based on the total weight of the hydrocarbon compound, aromatic 11ffJ alcohol, sodium stearate, and water. At this time, the aromatic monohydric alcohol remains as a residual component after the hydrocarbon compounds and aromatic components are volatilized, so there is a large amount of gel residue, which makes it difficult to determine when the fragrance is used. However, depending on the use of the above-mentioned aromatic monohydric alcohol, the IFf fragrance composition tends to melt and develop color when placed at a high temperature of about 60°C. In severe cases, the gel completely changes to a liquid state and the gel is destroyed.

<Object of the Invention> The present invention provides a gel-like fragrance composition that does not have the drawbacks of the prior art, has a transparent aesthetic appearance when beaten, has high shape and consistency even at relatively high temperatures, and has a low gel residual amount after being roughly volatilized. It is an object of the present invention to provide a transparent gel-like fragrance composition in which the amount of use of the fragrance is clear, and therefore the end of use of the fragrance is clear.

<Structure of the Invention> In order to couple the above objects, the present inventors conducted intensive ω1 research and found that when using sodium stearate as a gelling agent for hydrocarbon compounds, in addition to a small amount of water, glycol The present invention was completed when the problems of the prior art were solved all at once by using 2-ethyl-1,3-hexanediol as a compound.

That is, the present invention provides a gel-like fragrance composition obtained by heating and dissolving a composition mainly consisting of a hydrocarbon compound, glycols, sodium stearate, and water, and then cooling the composition, in which the glycol is 2-ethyl-1,3-hexanediol. The present invention provides a transparent gel-like fragrance composition characterized by the following.

The transparent gel fragrance composition of the present invention comprises a hydrocarbon compound, 2
- Ethyl-1,3-hexanediol, sodium stearate, water, etc.
1 can be produced by mixing, heating and melting the mixture at a temperature of about 90° C. and then letting it cool or forcibly cooling it to the lowest temperature. At this time, the hydrocarbon compound itself can be used as the aromatic component, but various synthetic fragrances and natural fragrances can also be used as other aromatic components. , mixed fragrances, etc. can be blended.

In this case, the temperature of the above-mentioned mixed 7JO hot solution should be set to about 65%.
Preferably, the temperature is lowered to about 80''C, then the aromatic component is added, mixed uniformly, and cooled.

2-ethyl-1,3 used in the composition of the invention
- The amount of hexanediol used is from about 2 to about 70% by weight, based on the total grams of hydrocarbon compound 2-ethyl-1,3-hexanediol, sodium stearate and water.

When the amount is less than about 2% by weight, the gel does not become transparent.

Further, if the amount is about 70% by weight or more, there will be a problem in transparency, so the amount should be appropriately selected within the above-mentioned range. Preferably about 2 to about 50
Weight % can be given as an example.

Examples of the hydrocarbon compound used in the composition of the present invention include volatile tenbel hydrocarbons and/or isoparaffin hydrocarbons. Volatile tenbel hydrocarbons include d-limonene, α-pinene, and β-
Examples include natural essential oils containing pinene and one or more of these compounds as main components, such as lemon oil, orange oil, and turpentine oil. Examples of isoparaffinic hydrocarbons include those whose main component has a boiling point of 150 to 270'C, such as IP Solvent 1620.2028 (manufactured by Idemitsu Petrochemical Co., Ltd.). The volatile tenbel hydrocarbons and isoparaffin hydrocarbons can be used by mixing them in any proportions. The amount of hydrocarbon compound used is hydrocarbon compound, 2-ethyl-
For example, from about 15 to about 96.5, based on the combined weight of 1,3-hexanediol, sodium stearate, and water.
A range of weight % can be exemplified. If the amount of hydrocarbon compound is too small, it will not be transparent, and if it is too large, it will not be transparent. Preferably about 15 to about 95
I can give an example of the highest percentage.

The sodium stearate used in the composition of the present invention does not need to be of particularly high purity, and easily available industrial products can be used. The amount of sodium stearate used is hydrocarbon compound, 2-ethyl-1,
For example, from about 1 to about 10% by weight, based on the total weight of 3-hexanediol, sodium stearate and water. If the amount of sodium stearate used is too small, a gel with appropriate hardness cannot be obtained, and if it exceeds 10 mm%, it becomes difficult to dissolve, which is not preferable. A preferred range is about 2% to about 8%.

The amount of water used in the present invention is about 0.1% to about 5% by weight, preferably about 0% by weight based on the total weight of the hydrocarbon compound, 2-ethyl-1,3-hexanediol, sodium stearate, and water. A range of .5 to about 4% can be mentioned.

The smaller the amount of water used, the better the heat resistance of the gel will be, but the sodium stearate will not be dissolved (and the transparency will be compromised.If the amount of water used is too large, the heat resistance of the gel will be improved.) This is not preferable as separation may occur. Therefore, it is used in a selective manner within the above range.

The transparent gel fragrance composition of the present invention comprises a hydrocarbon compound, 2
- Ethyl-1,3-hexanediol, siliium stearate, and water as well as synthetic fragrances as aromatic ingredients;
Natural fragrances, mixed fragrances, etc. can be selected and used in the confession. Examples include citrus fragrances such as lemon and orange fragrances, pine fragrances, rose fragrances, muguette fragrances, jasmine fragrances, and hyacinth fragrances. Examples of prescriptions for mixed fragrances include the following:

Excessive use end is not preferable because it may result in poor gel formation and may also cause an increase in cost.

The transparent gel-like fragrance composition of the present invention has two characteristic components:
Of course, ethyl-1,3-hexanediol can be used alone, but there is no problem in using it in combination with other organic solvents as long as the essence is not lost. For example, the volatility of aroma components can also be improved by using ethanol in combination. The amount used may range from about 1% to about 10% by weight, depending on the composition composition. If it exceeds about 10% by weight, it may have an adverse effect on the heat resistance of the gel, so care must be taken when using it.

In addition to the above-mentioned components, the transparent gel fragrance composition of the present invention can also be used as an antioxidant, pigment, odor agent, insect repellent, antiseptic bactericide, insect repellent, thickener, etc., if desired.
