JP2002062092A - Tear spray and tear solution for burglar repulse - Google Patents

Abstract

PROBLEM TO BE SOLVED: To provide a tear solution for burglar-repulsive spray comprising ethanol extract, such as cayenne pepper, wasabi, etc. SOLUTION: A tearing component is extracted with ethanol from cayenne pepper, wasabi, etc., to obtain an ethanol extract. The extract is diluted with water to less than 60 v/v % of alcohol concentration to obtain a fire undangerous substance of a higher flash point. In this case, if the ethanol extractant is merely diluted with water, the solubility is lowered to separate the solute. So a nonionic surfactant is added to the extractant to restrain its separation. The used ethanol extractant is of 5-40 wt.%, and the surfactant is of 0.01-3 wt.%. The tear solution is filled in a spray container 1 and is sprayed through a nozzle in a bar state or radially in a coarse-particle state to extend the range.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tear spray for crime prevention and an aqueous tear tear solution used for shooting down or protecting a molester in an emergency.

[0002]

2. Description of the Related Art CN gas (chloroacetophenone) and CS gas (oise chlorobenzaromarononitrile), which were originally used for military and security purposes, are used for civilian crimes for killing or molesting molesters. It has been used as an ingredient in tear sprays. In addition, OC gas (oleoresin / capsium) mainly containing an extract of red pepper is also used.

[0003]

However, since these tear gas emits in gaseous form, the radiation distance is short, it is difficult to aim at the face of a thug from a remote place, and it is easily affected by the wind outdoors. Sometimes flowed back to the sprayer. In particular, CS gas has a large biochemical effect, and when sprayed in large quantities against a thug, there is a danger of sequelae such as respiratory disorders and skin irritation. On the other hand, tear gas containing red pepper extract as a main component has no risk of sequelae against thugs, but in this red pepper extract, water-soluble combustibles such as ethanol are used as the extraction chemical. Because of the flammability, the spray container itself was dangerous because it was strictly prohibited from fire. As a countermeasure, it has been found that the alcohol concentration of the ethanol extract of red pepper may be diluted with water until the flash point is raised. However, it has been found that simply diluting with water lowers the solubility and precipitates the pepper extract.

The present invention has been made on the basis of this finding. In an aqueous tear solution containing an ethanol extract such as pepper, the flash point of the extract can be increased to reduce the risk of fire, and the extract The purpose of the present invention is to stabilize the solution by suppressing the precipitation of. The present invention also provides
To provide a tear spray for crime prevention, which can extend the flight distance of the tear water so that it can be effectively attacked even from a distant place, and is less susceptible to the wind even outdoors and can be used under headwinds Aim.

[0005]

The aqueous tear solution of the present invention comprises:
It is characterized in that an ethanol extract obtained by extracting a tear stimulating substance from pepper or wasabi with ethanol is diluted with water to an alcohol concentration of less than 60 v / v% and a surfactant is added. In this case, the ethanol extract is preferably 5 to 40% by weight, and the surfactant is preferably 0.01 to 3% by weight.

A tear spray for crime prevention according to the present invention is characterized in that it comprises a spray container filled with the above-mentioned tear-water solution, and a nozzle for emitting the tear-water solution from the spray container in the form of rods or coarse particles. It is.

[0007]

By diluting the alcohol concentration of the ethanol extract in the aqueous tear solution with water to less than 60 v / v%, it can be made non-dangerous in accordance with laws and regulations relating to dangerous substances.
Further, when the ethanol extract is diluted with water, the solubility of the extract can be increased due to the solubilizing effect of adding a surfactant to the extract, and the precipitation of the extract can be suppressed.

According to the tear spray for crime prevention of the above construction,
As it can be radiated in the form of rods or coarse particles as a method of spraying tear water, the flight distance can be extended,
It can be attacked from a distant place to ensure personal safety, is not easily affected by the wind, and does not flow backward due to the wind direction.

[0009]

BEST MODE FOR CARRYING OUT THE INVENTION The aqueous tear solution according to the present invention extracts capsaicin, a tear-stimulating substance, as a pungent component from pepper with ethanol, and extracts the ethanol extract with an alcohol concentration of less than 60 v / v%, more preferably 10 to 10%. 20v / v%
Until diluted with water, and a surfactant was added thereto to prepare the mixture.

In this case, the ethanol extract is 5 to 40% by weight, more preferably 8 to 20% by weight, and the surfactant is 0.0
1 to 3% by weight, more preferably 0.03 to 0.1% by weight is blended. If the amount of the ethanol extract is less than 5% by weight, the tearing effect is small, and if it exceeds 40% by weight, the tearing effect due to the increased amount is not added and the risk of ignition increases. If the amount of the surfactant is less than 0.01% by weight, precipitation of the extract cannot be suppressed. If the amount of the surfactant exceeds 3% by weight, it is economically disadvantageous and wasteful.

The alcohol concentration of the ethanol extract is adjusted to 60
By diluting with water to less than v / v%, it can be made non-hazardous in accordance with dangerous goods laws and regulations, and 10 to 20 v / v
%, The flammability can be further reduced and the safety can be further improved.

Surfactants include nonionic surfactants (for example, Nonipol series manufactured by Sanyo Chemical Industries, Ltd.), cationic surfactants (for example, Aromox series manufactured by Lion Corporation), and anionic surfactants (for example, Kao Corporation) (Emar series manufactured by Kao Corporation) or an amphoteric system (for example, Amphitol series manufactured by Kao Corporation). When these surfactants were added when diluting the alcohol concentration of the ethanol extract with water, the solubility of the extract could be increased by its solubilizing action, and the precipitation of the extract could be suppressed.

Tear stimulants can also be extracted with ethanol from non-toxic plants other than pepper, such as wasabi, mustard, curry powder and pepper. Wasabi is allyl isothiocyanate + butyl isothiocyanate, mustard is allyl isothiocyanate, curry powder is a multi-component mixture, and pepper is alkaloid, pipedine, and chavicin.

The above-mentioned aqueous solution for tearing is filled in a spray container 1 as shown in FIG. The nozzle 4 is capable of sucking up the tear water solution and emitting it in the form of a rod (linear) or coarse particles. By irradiating the aqueous tear solution from the nozzle 4 in the form of rods or coarse particles, the flight distance of the aqueous tear solution can be extended, and it can also be used under headwinds. Useful for self-defense.

[0015]

According to the aqueous tear water solution of the present invention, precipitation of the extract can be suppressed while the risk of fire of the ethanol extract can be reduced, and the solution can be stabilized. According to the tear spray for crime prevention of the present invention, in addition to the above-mentioned effects of the tear-water solution, the flight distance of the tear-water solution can be extended, and it is hardly affected by the wind, so that a thug can be shot down or protected in a distant place or outdoors. It is effective for use.
