JPS6039643B2 - Repellent for cockroaches, mosquitoes, etc. - Google Patents

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an effective repellent that is not toxic to the human body, and particularly to a repellent that is effective against cockroaches.

Various insecticides have been proposed in the past, but all of them contain ingredients that are harmful to the human body.

Therefore, care must be taken when handling tableware, skin, food and drink, etc.
It was necessary to prevent it from getting on children's toys or animal feed, but the inventor of the present invention turned his thoughts to repellents rather than insecticides, so that even if it gets on tableware, leather, children's toys, etc., it is harmful. We attempted to research a repellent that does not require sex. In order for a drug to be harmless to the human body, it must first be used as a drug that is not harmful to the human body.

Therefore, the following drugs were selected. [1- Ethanol: It is a raw material for synthetic alcoholic beverages and is harmless to the human body.

'2' Assembly: It is used as a stomachic medicine and is harmless to the human body.

{310 Camphor: It is safe to administer 0.3 ta per day as a cardiotonic agent, and it is harmless to the human body if used in small doses.

'41 Cinnamon oil: Used as a flavoring agent in medicine and food, and is harmless to the human body.

To 100 parts of Japanese Pharmacopoeia ethanol (concentration 95%) or proprietary alcohol (ethanol concentration 95%), 0.5 to 1.5 parts (weight ratio) of shredded Japanese Pharmacopoeia Assemblage are added. If the amount of Assemblage is less than 0.5 parts, the repellent effect will be reduced, and if it is more than 1.5 parts, it will remain undissolved in ethanol, which is uneconomical. If you put the shredded Assemble into ethanol and leave it for about 2 days, the solutes in the Assemble will dissolve into the ethanol. After that, a sieve solution A is obtained. Japanese Pharmacopoeia D camphor 6 to 1 (weight ratio) is added to and dissolved in part of solution AIOO to obtain solution B.

If the amount of D-camphor added is less than 4 parts, the repellent effect will be small, and if it is more than 1 part, there is concern that it may have an adverse effect on the human body. To the solution BIO Ikarito', add 0.3 to 1.5 parts (weight ratio) of cinnamon oil and mix well.

Cinnamon oil eliminates the unpleasant odor of D-camphor, and if the amount of cinnamon oil is less than 0.3 parts, the repellent will have a bad scent, and
．． If it exceeds 5 parts, the scent will be too strong and you will feel disgusted. Through the above steps, the aerosol repellent according to the present invention is manufactured. This aerosol repellent is highly concentrated and cannot be passed through hand sprays. Add 50 to 8 parts of water (by weight) to 10 parts of repellent for air soles and mix well to produce a repellent for hand spray. The repellent according to the present invention does not have the power to kill cockroaches or mosquitoes, but has the effect of keeping these insects away.

The repellent according to the present invention has the following characteristics. [a)
The liquid repellent produced for aerosol can be used for hand spray by simply adding an appropriate amount of water, making it easy to produce and handle.

‘.

} There is no danger to humans or animals, and it can be sprayed directly onto tableware, skin, and children's toys. It is flame retardant, so it is less dangerous.

Furthermore, the repellent according to the present invention also has the following effects.

■ You can kill a slug by throwing dawn mist on it.

@ Applying it to the area of your body that has been bitten by an insect will reduce the appearance of hair and speed up healing. Example 1 Japanese Pharmacopoeia ethanol (concentration 95%) 325 ml (Put 2.5 liters of chopped Chinese cabbage in it, let it stand for 2 days, and then mix it with water to make a solution A of about 300 ml.

Add and dissolve Japanese Pharmacopoeia D Camphor 24 in solution A to prepare solution B.

Add cinnamon oil (concentration 100%) to solution B and mix well.

The resulting product contains approximately 90% ethanol. The repellent prepared above was put into an air sole sprayer and sprayed in the kitchen and bedroom at a ratio of 1:1 to 1:1.

As a result, the data shown in Table 1 were obtained. (The mosquito experiment was conducted in a closed room.) Table 1 ◎ Presence of cockroaches and mosquitoes was observed.

x The presence of cockroaches and mosquitoes is not observed.

○ Slight presence of cockroaches and mosquitoes is observed.

Example 2 Japanese Pharmacopoeia Ethanol (concentration 95%) 325
Put 2.5 liters of cut-off Assemblage into the ground, leave it for 2 days, and then make Solution A with 300 ounces of sarugashi.

Add Japanese Pharmacopoeia D camphor 21 to solution A and dissolve it to prepare solution B.

Add cinnamon oil (concentration 100%) to solution B and mix well.

The resulting product contains approximately 90% ethanol. When the repellent prepared above was tested in the same manner as in Example 1, the results shown in Table 2 were obtained.

Table 2 Example 3: Put 2.5 liters of shredded assemblage into Japanese Pharmacopoeia ethanol (concentration 95%) 325', leave for 2 days, and sieve through a sieve to prepare solution A of about 300'.

Add camphor D18 of this Pharmacopoeia to solution A and dissolve it to prepare solution B.

Add cinnamon oil (concentration 100%) to solution B and mix well.

The brewed product contains approximately 90% ethanol. The repellent prepared above was tested in the same manner as in Example 1, and the results shown in Table 3 were obtained.

Leopard Table 3 Example 4 Add 200 parts of water to 300 parts of the repellent of Example 1, and shake well.

The resulting product contains approximately 55% ethanol. If the repellent made in the above manner is left for a while, it may form a precipitate, but once it is shaken, it immediately dissolves, so its effectiveness remains the same.

This repellent was placed in a hand-held sprayer and sprayed in the kitchen and bedroom at a ratio of 1:1. As a result, the data shown in Table 4 was obtained. (The mosquito experiment was conducted in a closed room.) Table 4 Example 5 Add 200 M of water to 300 M of the repellent of Example 2 and shake well.

The resulting product contains approximately 55% ethanol. When the repellent prepared above was tested in the same manner as in Example 4, the results shown in Table 5 were obtained.

Table 5 Example 6 Add 200 g of water to 300 g of the repellent of Example 3 and shake well.

The resulting product contains approximately 55% ethanol. The repellent prepared above was tested in the same manner as in Example 4, and the results shown in Table 6 were obtained.
