JPS602062B2 - solid aroma composition - Google Patents

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an aromatic composition in which a fragrance is solidified into a gel with a solidifying agent for use in producing or deodorizing a building interior, a car interior, or the like.

There are various desirable performances required of this type of solid aroma composition, such as no discoloration, no cracking, no separation of aromatic components, and strength that does not easily crumble when handled. In addition to the performance of having a
It is desirable that the fragrance lasts long and that it shrinks and becomes smaller as the fragrance components volatilize without damaging its appearance.

Conventionally, aromatic compositions formed into gel bodies have been generally satisfactory in the former performance, but have not been satisfactory in the latter performance.

This is due to the selection of raw materials, especially the solidifying agent, and the blending ratio of the solidifying agent and fragrance. By the way, conventional products of this kind have the need to reduce the bran separation phenomenon and have strength.
The fragrance content had to be limited to 90% by weight or less. The present inventors have conducted various studies with the main purpose of obtaining a solid aroma composition that has the above-mentioned desirable performance and also has a highly transparent and beautiful gel form. The present inventors have discovered that the above object can be achieved by mixing a terbene-based hydrocarbon having a chemical nature with an oxyfatty acid having 12 to 22 carbon atoms and 1 to 2 hydroxyl groups, and have thus arrived at the present invention. .

The present invention will be explained in more detail as follows.

In order to achieve the object of the present invention, it is necessary to use a raw material that can contain at least 9% by weight of perfume and 4 to 4% by weight of shading agent.

For this reason, the thebenbene hydrocarbon having aromatic properties is preferably used as the fragrance, and the oxyfatty acid having 12 to 22 carbon atoms and 1 to 2 hydroxyl groups is preferably used as the solidifying agent.
Examples of aromatic thebenene hydrocarbons, that is, monoterbene hydrocarbons, include limonene,
Examples include myrcene, chiren, ocimene, binene, chirenfuene, terbinolene, tricitalene, terbinene, fentin, phelandrene/silvestrene, and sapine.

Depending on the purpose of use and desired flavor quality, very small amounts of other blended fragrances may be added as long as they do not interfere with the purpose of the present invention. Examples of oxyfatty acids include oxystearic acid and dioxystearic acid.

When the oxyfatty acid has one carbon number and three hydroxyl groups or less, the amount added cannot be suppressed to 4 to 1% by weight as described above, and the strength of the obtained solid aroma composition decreases. , and if there is no hydroxyl group, it will not gel.In addition, as fatty acids containing these for industrial use, inexpensive and commonly available ones, that is, commercially available ones, are used. There are fatty acids with 8 to 22 carbon atoms, and since they cannot be passed through the present invention under the limit of 1 carbon number, the oxyfatty acids that can be used in the present invention are those with 12 to 22 carbon atoms. By the way, oxyfatty acids with 23 or more carbon atoms are also effective, but it is expensive to synthesize them and use them.
It's not practical. The composition of the present invention can be easily obtained by mixing the above-mentioned raw materials, heating the mixture at a dripping temperature to uniformly dissolve it, and then cooling it to room temperature to solidify.

In this case, no other solidification aids are required, but if necessary, antioxidants such as BHA (
butylated hydroxyanisole) and BHT (dibutylated hydroxytoluene) may be added alone or in combination. The composition of the present invention thus obtained has all the desired properties described above and can achieve the intended purpose.

This mainly uses terbene carbon and oxyfatty acid, and since these have good compatibility and affinity, it is possible to contain the former as an aromatic component in an amount of 9% by weight or more. That is, this is because it is possible to suppress the content of the latter as a solidifying component to 4 to 1% by weight. In particular, according to the present invention, it has appropriate ballistic properties and high transparency, and this transparency is maintained until the end of volatilization of the aromatic components.

Furthermore, since it does not contain any film-forming components, a stable volatile state can be obtained throughout the period of use. In addition, as the aromatic components volatilize, it shrinks and becomes smaller without impairing its aesthetic appearance, and it becomes extremely small after use, so it can be used as a guide for when use is finished. In addition, the composition of the present invention has high transparency;
In addition, since the aromatic components are retained until the end of volatilization, if a desired character or other decoration is embedded inside the composition when it is molded, the aesthetic appearance will be further improved, and the product will have a sense of taste and commercial value. Becomes a product.

In Examples 1 to 4 and Comparative Examples 1 to 5, as shown in the table above, d-limonene was used as the fragrance, and each solidifying agent was blended with the d-limonene, and the mixture was heated to 60 to 65 oo and uniformly mixed. After dissolving, it was cooled to room temperature. In Examples 1 to 4, 4% by weight and 1% by weight of oxystearic acid and dioxystearic acid were added as solidifying agents.
It was a highly transparent gel body that was elastic and had sufficient strength, with very little detachment phenomenon.

In Comparative Examples 1 to 5, those to which 1% by weight of stearic acid and sodium stearate were added did not gel. In addition, both hydrogenated castor oil and polyethylene (molecular weight 40,000, density 0.92) with 10% by weight added have low strength and many mechanical problems, making them unsuitable for use and having very low transparency. It was a gel body. Furthermore, a mixture of hydrogenated castor oil and polyethylene (molecular weight 40,000, density 0.92) in an amount of 5% by weight did not gel. Next, the volatilization state of the gel body of Example 1 and the gel bodies of Comparative Examples 6 and 7 below at room temperature was tested, and the results are shown in the attached drawings.

As can be seen from the drawing, the gel body of the above example exhibited a stable volatile state throughout the period of use. In the gelled body of Comparative Example 6, since butadiene rubber with film-forming properties was added, the initial volatilization state was stable, but after the middle stage, a film was formed on the surface of the gelled body, and volatilization was hindered.
Further, in the gel body of Comparative Example 7, 50% of the total amount was lost due to initial volatilization, and volatilization was extremely poor after the middle period, and a stable volatilization state was not exhibited throughout the period of use.
