Description

The present invention relates to an improvement of a pest control incense stick.

Pest control incense typified by mosquito coils are mainly used to control adult mosquitoes, and have long been popular as an indispensable item in summer in ordinary households. The mosquito coil was devised in 1890, and at that time the rod was about 30cm long and the burning time was about 1 hour, but after that the shape of the mosquito coil was changed from a rod to a spiral. Also, the burning time for one bottle was about 7 to 8 hours according to the human bedtime. Swirl incense is convenient because it can be easily used anywhere in a match, maintains a certain insecticidal effect until it burns out, and excels in the diffusion of active ingredients. It can be said that the insecticidal form.
The pest control incense stick is mixed with an aqueous solution containing a coloring agent to a mixed powder containing an active ingredient, a binder, a plant powder, etc. In general, it is punched into a shape mold and dried to a moisture content of about 5 to 10%. In this case, it is usual to prepare various colors by using various colorants.

As the colorant, a blending ratio is determined according to various colors and used at various concentrations.
Malachite green has long been used as a colorant, but recently, various raw materials have been used as various pigments. Among these, it is common to use materials whose safety has been confirmed, such as legal dyes and food dyes.
However, when these dyes are used as pest control incense sticks, sufficient consideration is given to the volatility of these dyes in a special dosage form called incense sticks that are used by smoking products. I couldn't say that there was a situation that needed further study.
