Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention attracts attention as one of the three major sanitary pests, along with flies and mosquitoes, and causes feeding damage and disgust in residential environments, and is also applicable to electronic information and communication equipment of companies, etc. cockroaches that cause malfunctions,
To provide a cockroach repellent that accurately repels cockroaches from a residential environment, is non-toxic, has a fragrance, and does not cause any disturbance to the residential environment.

Conventional methods for controlling cockroaches include spraying or applying highly persistent insecticides to cockroaches' hiding places and passageways, trapping them using containers containing both attractants and adhesives, and methods for repelling cockroaches. There are ways to avoid it using chemicals.

In the various methods described above, methods using insecticides and adhesives have been used, but these methods are not necessarily preferred due to their toxicity and disgust at the sight of carcasses.

Currently, the active ingredients of cockroach repellents include cinnamyl alcohol, methyl eugenol, etc.

etc. are disclosed. However, these active ingredients are not necessarily satisfactory, and there are very few examples of them being put on the market.

[Problem to be solved by the invention]

Cockroaches are insects that belong to the order Orthoptera, and about 20 species are known to live in Japan alone. The three most common sanitary pests that attract attention are the German cockroach, the black cockroach, and the Japanese cockroach.

Cockroaches, like flies, are said to carry various pathogens, and are not only unhygienic, but also cause serious damage to their diets, and will crawl out of their hiding places at night to scavenge for water and food.

Cockroaches prefer warm places in the home and often congregate in kitchens where they have good access to water and food. In recent years, as the heating situation has improved, German cockroaches in particular live in the pill all year round and multiply, causing not only C1 feeding damage but also building nests in office equipment and causing information and communication failures, which has become a major social problem.

The present invention targets cockroaches, particularly the German cockroach, and aims to provide a repellent that repels cockroaches such as the black cockroach and the Japanese cockroach, which show a habitat distribution similar to that of the German cockroach and mainly cause damage to facilities in buildings. It is something.

[Means to solve the problem]

In order to solve the above problems, the present inventors conducted research on a cockroach repellent substance that does not have toxicity or odor even when used indoors, and developed a rose-based floral-tone formulation for cosmetics. The present invention was completed by discovering that fragrances surprisingly have a strong repellent effect against cockroaches, especially the German cockroach.

The present invention is a cockroach repellent containing a rose-based floral fragrance.

The rose-based floral fragrance that is the active ingredient of the present invention is
Geraniol and benzyl acetate are commonly used as fragrances in cosmetics, etc.

products) etc.

The geraniol, phenylethyl alcohol, and tetrahydrolyalol contained in this fragrance have a rose-like aroma, and both are used in eight rose-based formulations. Lialole is a substance with a lily-like fragrance, benzyl acetate is a substance with a jasmine-like fragrance, and cyclamenaldehyde is a substance with a cyclamen-like fragrance, and both are preferably used as a floral preparation ingredient.

These substances are known compounds and have been widely used as cosmetic fragrances due to their non-toxicity and aromatic properties.

For the cockroach repellent of the present invention, the above-mentioned rose-based floral fragrance may be used as it is.

However, depending on the intended use, liquid formulations, coating agents such as aerosol formulations, or gel formulations, and bases commonly used in such formulations.

Prepare by the usual method using auxiliary agents etc.

By containing the rose-based floral fragrance as an active ingredient in these preparations in an amount of 1% (by weight) or more, preferably 5% (by weight) or more, a sufficient repellent effect can be achieved.

In addition, other cockroach repellents may be used in combination with this preparation as appropriate depending on the place of use, conditions of use, etc.

In addition, when using the active ingredient of the present invention as it is without formulating it, since the rose-based floral fragrance is usually a liquid, it can be applied or sprayed directly to the area of use, or
Alternatively, it may be used by adding it to a coating agent such as a paint. Also,
Nets, robes, cords, cloth.

It can also be held and used by holding means such as impregnating or kneading into paper or gel material.

The active ingredient of the cockroach repellent of the present invention is originally used as a fragrance, so it goes without saying that it has a fragrance and does not cause disgust to people, but rather has a scent that people like. have. Furthermore, since it is colorless and transparent, even if it is held in another object, it will not affect the color of the object at all.

The cockroaches to be repelled by the repellent of the present invention are cockroaches that cause harm to the living environment, such as the German cockroach, black cockroach, and Japanese cockroach. It is effective against

Test Example 1 a) Sample sample Repellent of the present invention in Example 1 b) Test method Fold a 6 x t3 cm filter paper into a corrugated shape large enough for German cockroaches to enter (hereinafter referred to as a shelter) and serve. The samples were applied by dipping. Next, a glass pot with a diameter of 15 cm and a height of 18 cm in which absorbent cotton impregnated with sugar water and feed for breeding insects was placed in the center, and the above shelter with repellent applied to opposite corners and an untreated control shelter. was placed on each.

To judge the repellent effect, place the above glass pot in a constant temperature room at 25°C with 12 hours of light and darkness, and test German cockroaches (Watata type).
A total of 20 adult cockroaches of 10 males and 10 females were released, a glass pot was covered with a breathable cloth, and the number of cockroaches in the shelter was determined over time.

Note that this test takes advantage of the tendency of cockroaches to gather in dark corners of spaces (shelters in the case of this test).
