[0001]

TECHNICAL FIELD The present invention relates to a pest repellent composition for humans or animals. More specifically, silicic acid anhydride porous fine particles are loaded with a repellent component, and further dispersed in a solvent together with synthetic resin fine particles, an aerosol product of a human or animal pest repellent and a spray of a human or animal pest repellent. It is about products.

2. Description of the Related Art Conventionally, N, N has been mainly used as a pest repellent.
-Diethyl-m-toluamide (hereinafter referred to as "diet") is dissolved in a solvent, concentrated glycerin, 1,3-butylene glycol, dipropylene glycol and the like are mixed, filled in an aerosol can, and liquefied petroleum gas is added. Starting with an aerosol-type pest repellent, further, in order to have a feeling of use and sustainability of medicinal properties, silicic acid anhydride porous fine particles are loaded with diet, and this is mainly dispersed in a solvent such as ethyl alcohol to improve the dispersion. Therefore, a technique for making a good dispersion liquid by using an acrylic acid polymer, an alkali salt, a surfactant and the like has been developed. The present inventors have disclosed that
-78057 "Aerosol composition and method for producing the same, and aerosol product using the same" discloses the technique.

On the other hand, in JP-A-7-126104, a human pest repellent composition which does not bleach, has a long repellent effect, and has a good feeling in use, has a specific surface area of 500 m ² / g or more. The silicic acid particles used to achieve the same purpose as a pest repellent composition are those having a pore volume of 1 m.
l / g or less, average pore diameter 100 Å or less, specific surface area 500
Techniques such as ones with less than m ² / g are disclosed. Furthermore, the pest repellent aerosol of Japanese Patent Application No. 9-157107 contains a low boiling point hydrocarbon, the injection amount is 2.0 to 5 ml per 3 seconds, and the oil absorption amount of the powder is 250 ml / 1.
The use of what is less than or equal to 00 g is disclosed. Also, British Patent No. 987,301 aerosol composition (PATENT SP
In ECIFICATION No.987,301 Aerosol Compositions), antiperspirant, deodorant, and other medicinal powders are filled as a stock solution with alcohol, dispersant, and colloidal silica (silicic acid anhydride) into a pressure-resistant can, and chlorofluorocarbon, LPG, etc. are sprayed on it. A technique for adding an agent to form an aerosol product is disclosed.

[0004]

When manufacturing pest repellents by the conventional techniques, one of the problems is the dispersion of the powder phase (solid phase) in the dispersion liquid. In other words, when putting the finished product as a well-dispersed stock solution in an aerosol can and installing a valve and filling the propellant,
This is a problem in that the dispersibility in the aerosol composition may deteriorate due to the properties of the propellant. For example, in the case of carbon dioxide gas, this is often due to the problem of pH, and in the case of liquefied gas, it is often due to the compatibility between the stock solution and the propellant. For this reason, it is difficult to use what is desired as an active ingredient, it is difficult to find a substitute, and it takes a lot of time to find a dispersant, an activator and a solvent.

Another problem is the redispersion of the powder phase. No matter how good the dispersibility is, the specific gravity of the powder phase of the dispersed phase is about 2.15, and the specific gravity of the solvent used is 0.82. When the product is allowed to stand for 10 days, 20 days, or for months, the solid phase is deposited on the liquid bottom. It is the engineer's pains to find out how to easily re-distribute this with a simple product vibration operation. That is, dispersant, wetting agent, selection of activator, combination, adjustment of liquid viscosity, particle size of powder, bulk specific gravity, surface treatment thereof,
Therefore, various experiments are required.

Yet another problem is how to effectively exert the effect of the powder phase, that is, the silicic acid porous fine particles, and to cover the drawbacks. The role of silicic acid anhydride porous particles is to support the active ingredient to prolong the drug effect time, to spread the particles on the skin surface for a longer staying time, and to improve the feel of the skin surface. Feeling and non-greasiness, and not giving a sensation of foreign body feeling, that is, not whitening.

[0007]

As a result of various investigations, in order to solve the above problems, the present invention introduces particles of other materials capable of preventing collision between particles into the silicic acid anhydride particle group. It has been found that an aerosol composition having a good compatibility, an aerosol composition having a good redispersibility and a powder phase composition having a good feel and not being whitened. That is, a repellent composition comprising silicic acid anhydride porous fine particles carrying a pest repellent, synthetic resin fine particles, and a solvent, wherein the solvent is preferably at least one or two of alcohol and water. The silicic acid anhydride porous fine particles have a particle size of 0.5 to 50 μm and an average particle size of 0.5 to 3
0.0μm, surface pore diameter 20-150Å, specific surface area 2
0-800 m ² / g, pore volume 0.01-150 ml /
g, which are non-hollow porous silica spherical particles or hollow porous silica spherical particles, and which are obtained by an interfacial reaction method, and have a surface pore diameter of 50 to 150Å of the total 40 to 90 Those occupying% are preferable. Further, it is preferable that the synthetic resin fine particles have an average particle size of 0.1 to 50 μm and are not physically adherent to the silicic acid anhydride porous fine particles.

A second aspect of the present invention is a pest repellent aerosol product for humans or animals, which is obtained by filling and sealing a repellent composition and a propellant in an aerosol pressure-resistant container, wherein the propellant is liquefied petroleum gas. , Liquefied gas such as dimethyl ether, compressed gas such as nitrogen gas, carbon dioxide gas, etc. 1
It is preferable to use one kind or a mixed gas of two or more kinds.

(Example 4) 9.0 g of diet (manufactured by Mitsubishi Gas Chemical Co., Inc.), 3.0 g of silicic acid porous fine particles (Godball E-6CK manufactured by Suzuki Yushi Kogyo Co., Ltd.), polyethylene powder (Sumitomo Seika Co., Ltd.) Made by company) 0.6g, 1,3-
Butylene glycol (Sakamoto Pharmaceutical Co., Ltd.) 3.0
g, 2.0 g of sodium polyoxyethylene oleyl ether phosphate (manufactured by Nikko Chemical Co., Ltd.), and 99% denatured alcohol were added to bring the total amount to 100 g, which was used as a pest repellent stock solution.

(Example 5) 8.0 g of Diet (manufactured by Mitsubishi Gas Chemical Co., Inc.), 3.0 g of silicic acid porous fine particles (Godball E-6CK manufactured by Suzuki Yushi Kogyo Co., Ltd.), polyethylene powder (Sumitomo Seika Chemical Co., Ltd.) Company-made company) 0.6 g, concentrated glycerin (Sakamoto Yakuhin Kogyo Co., Ltd.) 2.5 g, sodium polyoxyethylene oleyl ether phosphate as a surfactant (Toho Chemical Industry Co., Ltd., phosphanol RO-720N) 2.0 g And 9 to 10.0 g of purified water
5% denatured alcohol was added to bring the total amount to 100 g, which was used as a pest repellent stock solution.

(Comparative Example 1) 7.0 g of Deet (manufactured by Mitsubishi Gas Chemical Co., Inc.), 3.0 g of silicic acid anhydride porous particles (Godball E-16C manufactured by Suzuki Yushi-Seiya Kogyo Co., Ltd.), and concentrated glycerin (Sakamoto Yakuhin Kogyo Co., Ltd.) 99% denatured alcohol was added to 3.0 g (manufactured by Co., Ltd.) to bring the total amount to 100 g, which was used as a pest repellent stock solution.

(Test Example 1) 45 ml of each of the stock solutions obtained in Example 1 and Comparative Example 1 was placed in a pressure-resistant glass bottle, and a valve was attached to fill with carbon dioxide gas to 5.5 kg / cm ² . As a result, the one containing the stock solution obtained in Example 1 was allowed to stand for one week, and the one left still was gently inverted from the bottle.
The white particles that seemed to stick to the bottom fell into the liquid, started to flow and disperse, and when this was repeated twice, almost completely dispersed. On the other hand, the one containing the stock solution obtained in Comparative Example 1 was
When left standing for 1 week and standing still, the bottle is gently inverted, and the white particle layer that adheres to the bottom often sticks to the bottom of the bottle and does not fall into the liquid. However, about one fifth of the amount still adhered to the bottom of the bottle.

As a result of this test, when the silicic acid porous fine particles and the polyethylene particles were allowed to coexist in the dispersion liquid, frictional electrification did not occur, and both original electrifications were negative, so that the interparticles were not charged. Collisions are combinations that can be prevented. In this case, it is desirable that the particle size of the polyethylene powder be equal to or larger than the particle size of the silicic acid anhydride porous fine particles or larger than the particle size of the silicic acid anhydride porous fine particles as shown in FIG. It reduces the particle size of silicic acid porous fine particles that are easily affected by pH, and increases the particle size of organic polyethylene particles, which are considered to be less susceptible to the effect of charge due to pH, to control the interparticle behavior due to charge. This is because That is, the particles are prevented from coagulating and exhibit good dispersibility in the dispersion liquid.

At this time, the content was sprayed onto human skin, and the touch was examined 5 minutes later. As a result, it was found that the undiluted solution of Comparative Example 1 was used when the undiluted solution of Example 1 was used. It was better than the one. This is presumed to be because, as shown in FIG. 4, the softness of polyethylene, which is soft, covers the hardness of the silicic acid anhydride porous fine particles, which are inorganic particles.
