Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides an effective repellent that is non-toxic to the human body, especially for cockroaches.
This relates to a repellent effective against 1#r.

Conventionally, various insecticides have already been proposed, but all of them contain components harmful to the human body. For this reason, it is necessary to be careful in handling and to prevent it from getting on tableware, skin, food and drink, children's toys, or animal feed. 1 tableware,
We attempted to research a repellent that would not be harmful even if it got on the skin or children's toys.

In order for a drug to be harmless to the human body, it is first necessary to use a drug that is not harmful to the human body. For this reason, we selected a drug that was lacking.

(11-tanol 2011 is a raw material for synthetic alcoholic beverages and is harmless to the human body.

(2) Aspergillus Stomach is used as a stomach medicine.

It is harmless to humans.

131D Force 0090 o, 3 per day as a cardiotonic agent
There is no problem in administering g, and it is harmless to the human body in minute amounts.

(4) Cinnamon oil 000. It is used as a flavoring agent in medicine and food, and is harmless to the human body.

Japanese Pharmacopoeia ethanol (concentration 95%) f or proprietary alcohol (ethanol concentration 95% llootJl, shredded Japanese Pharmacopoeia Senda 11 0.5 to 1°5 parts tff
i quantity ratio). 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, dissolution in ethanol will leave a residue, which is uneconomical. After putting the shredded sender 11 into ethanol, if it is left for about two days, the solute of the assembly will dissolve in the ethanol. [, Karuno is also filtered to obtain solution A.

4 to 10 parts (by weight) of Japanese Pharmacopoeia D camphor are added to and dissolved in 100 parts of Solution A 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 10 parts, there is concern that it may have an adverse effect on the human body.

Add 0.3 to 1.5 parts (weight ratio) of cinnamon oil to 100 parts of solution B and mix well. Cinnamon oil eliminates the peak of D camphor. If the amount of cinnamon oil is less than 0.3 parts, the repellent's scent will become angry, and if it exceeds 15 parts, the scent will be too strong. I feel disgusted. Through the above steps, the aerosol repellent according to the present invention is manufactured.

This aerosol repellent is highly concentrated and is not suitable for hand spraying. When you add 50 to 80 parts of water (I-water ratio) to 100 parts of aerosol repellent and shake well, 1 hand press 1. A spray repellent is produced.

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 features.

It is easy to manufacture and handle because it can be used as a one-hand spray by simply adding an appropriate amount of water to the liquid repellent made for the old Koryozor.

(b) There is no danger to humans or animals, and it can be sprayed directly onto tableware, skin, and children's toys.

(c) It is flame retardant, so it is less dangerous.

Moreover, the repellent according to the present invention 1 also has the following effects.

■You can kill slugs by spraying them.

@If you apply it to the area of the wood that has been bitten by an insect, it will cause itching.
It can be cured early.
