Abstract

PURPOSE:A mothproof agent, containing a <=5C alcohol as an active constituent, capable of exhibiting the mothproof effect by evaporation thereof in a closed container for containing clothing, etc., and lasting the effect thereof for a long period without deteriorating the effect even in a container with insufficient closing degree. CONSTITUTION:A mothproof agent, obtained by previously impregnating a filter paper, etc., with a <=5C alcohol 2, e.g. ethanol, or forming the alcohol into a gel or solid shape with a gelling agent or swelling agent, etc., and putting the alcohol in a closed container 1, e.g. a baglike film having a closable and openable chucklike opening part 4, and containing clothing 3. EFFECT:The evaporation rate is high and the effect is powerful. Eggs, imagoes and larvae of injurious insects for clothing can be exterminated, and the safety for human bodies is high without giving damage to clothing or attachments thereof nor attacking the plastic in the container. Alcoholic smell is not left in the clothing, and the alcohol has antifingal and germicidal effect, and therefore is suitable even for containing and storing the clothing in a plastic container.

Description

[Detailed description of the invention] [Industrial field of application] The present invention uses alcohol of C3 or less as an active ingredient,
.

This invention relates to an insect repellent that is effective by being volatilized in a container for storing clothing, etc.

[Conventional technology]

Conventional insect repellent, especially as an insect repellent for clothing, etc. (1)
'Paracyclobenzene, (2) Naphthalene, (
3) Camphor, (4) pyrethroids, (5) oxygen scavengers, etc. are used. Among these, items (1) to (3) have a strong odor, making it difficult to wear them immediately after taking them out of storage, and item (4) is very expensive and not common. Furthermore, since (5) is effective in combination with a container having high oxygen impermeability, there are limitations in practical use.

[Problem that the invention seeks to solve]

Recently, the storage formats for clothes have become more diverse, and they are often stored in poorly sealed places such as closets and fan cases. In many cases, insect repellents alone are not effective.

In view of the above-mentioned circumstances, the inventors of the present invention have intensively investigated various insect repellents suitable for storage formats, and as a result, have discovered that alcohols have strong insect repellent properties, and have arrived at the invention described below.

[Means for solving problems]

That is, the present invention is an insect repellent made by volatilizing alcohol of C3 or less in a closed container.

Alcohols with C6 or lower include methyl alcohol, ethyl alcohol, flobyl alcohol, pulcohol, fluorol, and amyl alcohol. Among these, methyl alcohol is toxic and has a low boiling point, while butyl alcohol and amyl alcohol have high boiling points. Therefore, ethyl alcohol, n-propyl alcohol, and i-7'' propyl alcohol are preferred.

A bag-like film is preferable as the airtight container used in the present invention. Since alcohols are highly polar, alcohol vapor is difficult to permeate through plastic films, and even polyethylene film, which is considered to have the highest permeability, has a small amount of permeation.

The effects of various types of alcohol vapor on plastic bags are shown in Table 1.

Table 1 (Container non-contact at 30° C. for 1 month) It is preferable that the bag-like film used as a sealed container has an opening on one side and can be opened and closed like a zipper, making it easy to put in and take out the alcohol storage container and clothes. (See figure) If you store clothes in this bag-like film and keep the opening sealed, the alcohol inside the bag-like film will evaporate and the alcohol vapor will fill up in a short time, causing eggs of pests attached to the clothes. , kills larvae and adults. Alcohol of 0.03 or lower evaporates particularly quickly, so the insect repellent effect is fast-acting, and the alcohol smell dissipates quickly and does not remain after clothes are removed.

It is also possible to store alcohol in liquid form in a container and place it in a bag-like film, but in order to prevent the alcohol from spilling if the container falls over, you can use P paper soaked with alcohol in advance, a gelling agent, or a swelling film. It is preferable to store it in a gel or solid form with an agent or the like.

〔Example〕

Example 1 One burr larva was placed in a 2t glass container with a slit septa.
0 head, about 50m9 of wool tip and 42 kinds of insect repellents,
It was left standing in a constant temperature bath at 20°C for one week. (However, the transpiration pyrethroid drug manufactured by Dainippon Pyrethrum was used for 201 minutes.

The deoxidizing acid is for air 3tC oxygen 600171/min. ) Table 2 Example 2 340m+++X 240wX Approximately 1 ton of air, 10 burr eggs, and 10 larvae in a 40 μm low-density polyethylene bag
and various insect repellents 42 (pyrethroid type and oxygen scavenger under the same conditions as in Example 1).

Table 3 shows the results of placing the bag in a thermostat at 20° C. and leaving it for one week.

Table 3 [Effects of the Invention] According to the present invention, since the active ingredient is alcohol, the evaporation rate is fast and the efficacy is strong, so it kills eggs, larvae, and adults of pests on clothing, and the effect lasts for a long time. Even if the container is not tightly sealed, the effectiveness will not be reduced. Since it is alcohol, it is highly safe for the human body, does not harm clothing or its accessories (metal, plastic, etc.), and does not attack the plastic containers. In addition, since the evaporation rate is fast, it is fast-acting and does not leave an alcohol odor on clothing. In addition, alcohol has fungicidal and bactericidal effects, so it is the most suitable insect repellent for storing clothing in plastic, and its range of uses is wide.
