Description

Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION The present invention relates to a discriminating agent and a fragrance composition containing the same.

[0002]

2. Description of the Related Art Conventionally, space identification has been performed by visual means such as a signboard and auditory means such as broadcasting. However, the present inventors have found that odor-based spatial identification using scent is also a useful identification means, and applied for a patent. (Japanese Patent Application No. 2-246064) However,
The relationship between the type of fragrance and the information transmission function has not been deeply examined. Therefore, little has been known about fragrances suitable for space discrimination based on the sense of smell. Furthermore,
No sense of odor was used as a means of other identification, such as identification of information.

[0003]

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a discriminating agent suitable for discriminating by smell and a perfume composition containing the discriminating agent.

[0004]

[Means for Solving the Problems] In order to solve the above problems,
As a result of intensive studies on the identification function of the fragrance in various fragrances, the present inventors have found that the primary alcohols or aldehydes having 6 carbon atoms are, in particular, hexanal, cis-3-hexenal, trans-2-hexenal,
They found that the scents of green fragrances such as cis-3-hexenol and trans-2-hexenol were excellent in this function, and completed the invention.

Here, the purpose of identification is to identify the space as the first supposed purpose, and the identification and guidance to the evacuation gates in the event of an emergency such as a disaster are the most important. Considered the purpose. Further, it is also conceivable that a specific meaning is given to a specific odor type in advance and, for example, information identification used for transmitting warning information or evacuation information. Therefore, the scent that can be distinguished from the scent that is generally present as a requirement for the identifying fragrance. The scent should be easy to identify even at low concentrations. It should be identified even when smells such as smoke are generated during a disaster. Not harmful to your health. Easy to vaporize, has a good odor, and has low storability. For example, it should not have a significantly unpleasant odor like pyridine. Is mentioned.

[0006] From such a viewpoint, primary alcohols or aldehydes having 6 carbon atoms, especially hexanal, cis-3-hexenal, trans-2-hexenal, cis-3-hexenol, and trans-2-hexenol are all green fragrances under all these conditions. Was satisfied. The discriminating agent of the present invention comprises these compounds.

Hereinafter, these discriminating agents will be described in detail.

Hexanal has the structure shown in Chemical formula 1 and is found in essential oils such as apple, strawberry, orange and lemon.

Cis-3-hexenal has a structure shown in Chemical formula 2, and it is known that cis-3-hexenal exists in leaves of trees as green leaf aldehyde together with trans-3-hexenal having the structure shown in Chemical formula 3.

Cis-3-hexenol has the structure shown in Chemical formula 4, and it is known that cis-3-hexenol exists in the leaves of trees as green leaf alcohol together with trans-2-hexenol having the structure shown in Chemical formula 5.

The fragrance composition of the present invention contains one or more of the above-mentioned discriminating agents. The preferable blending amount of the discriminating agent of the present invention in this fragrance composition is 10 to 90% by weight. This is because if the content of these compounds is less than 10%, the scent is too thin to be identified, and if the content exceeds 90%, the identification effect reaches the ceiling.

The fragrance composition of the present invention includes hexanal,
In addition to the discriminating agent of the present invention such as cis-3-hexenal, trans-2-hexenal, cis-3-hexenol, trans-2-hexenol, etc., as an optional component, a solubilizing medium such as ethanol, propanol, propylene glycol, glycerin, water, silica gel, polyacryl resin And the like, antioxidants, preservatives, fragrances such as benzyl alcohol, and commonly used fragrances can be added.

The fragrance composition thus obtained has a so-called green scent, and unlike general scents, it is easy for anyone to notice and to easily identify the type, so that it is easy to identify in smoke such as fire. In addition, if it is given a specific meaning in advance, its meaning can be understood immediately, so it can be used as a means of transmitting information, and since it does not cause discomfort unlike pyridine, it is suitable as a perfume composition for identification. is there. This effect is not obtained simply because it is easily volatilized, and one or more selected from the discriminating agents of the present invention such as hexanal, cis-3-hexenal, trans-2-hexenal, cis-3-hexenol, trans-2-hexenol, etc. It is obtained as a scent characteristic possessed by the fragrance composition of the present invention, which contains ˜90% by weight.

In order to use the fragrance composition of the present invention for identification, a means for vaporizing is required, but the means for vaporizing is not particularly limited. For example, a method for vaporizing from a cotton core or the like, spraying as an aerosol. Examples thereof include a method of vaporizing by evaporation, a method of vaporizing by heating, a method of vaporizing by ultrasonic waves, and the like.
The concentration of the discriminating agent of the present invention when vaporized is 0.1 to 30.
It is preferably adjusted to be μg / m ³ . More preferably, it is 0.5 to ³ μg / m ³ .

Hereinafter, the present invention will be described in more detail with reference to Examples, but it goes without saying that the present invention is not limited to these Examples.

Example 1. Fragrance composition The following ingredients were weighed out and mixed by stirring to obtain a fragrance composition. Hexanal 20 cis-3-hexenal 30 cis-3-hexenol 30 Ethanol 20

Example 2. Fragrance composition The following ingredients were weighed out and mixed by stirring to obtain a fragrance composition. Cis-3-hexenal 20 benzyl alcohol 30 ethanol 50

Embodiment 3 FIG. Fragrance composition The following ingredients were weighed out and mixed by stirring to obtain a fragrance composition. Hexanal 20 cis-3-hexenal 40 trans-2-hexenal 10 Synthetic musk 5 Propylene glycol 15 Ethanol 10

Example 4. Fragrance composition The following ingredients were weighed out and mixed by stirring to obtain a fragrance composition. Hexanal 10 trans-2-hexenal 10 trans-2-hexenol 10 BHT 1 butylparaben 1 water 18 triethyl citrate 10 ethanol 30

Embodiment 5 FIG. Spatial identification test Using the fragrance compositions of Examples 1 to 4, the space identification function of the fragrance composition of the present invention was measured. That is, 2 in a room of 62.5m ³ with 4 entrances in front and back
Put in 0 panelists, spray the fragrance compositions of Examples 1 to 4 at a concentration of 1 μg / m ³ from any of the four entrances so that the panelists can smell, and the panel will smell from which entrance. I got an answer. The correct rate at this time is shown in Table 1. From this, it can be seen that the fragrance of the present invention was used for spatial recognition.

[0026]

[Table 1]

Example 6. Discrimination Test Using the fragrance compositions of Examples 1 to 4, the space identification function of the fragrance composition of the present invention was measured in the presence of other scents. That is, a room of 62.5 m ^{3 with} a total of 4 entrances on the front and back, is filled with a fragrance amount of 1 μg / m ³ in advance, and then 20 panelists are put in.
From one of the two entrances, the fragrance compositions of Examples 1 to 4 were sprayed at a concentration of 1 μg / m ³ so that the panelist could not see, and the entrance was asked by the panelist from which entrance. The correct rate at this time is shown in Table 2. From this, regardless of the presence or absence of other fragrance, by the fragrance of the present invention,
It can be seen that the space was recognized. Furthermore, since it is distinguished from other fragrances by the sense of smell, if the meaning of the odor of the fragrance composition of the present invention, such as a danger signal, is agreed in advance, it can also be used as a means of transmitting a danger signal. It turns out that it can be.

[0028]
