Description

Anti-mosquito fungicide

The present invention relates to an anti-mosquito agent, in particular to an anti-mosquito bactericide.

The main components of commercially available anti-mosquito liquids are chemically synthesized (DEET or Picaridin) and natural essential oils. Among them, DEET (enemy avoidance) is a synthetic chemical substance that gives people an uncomfortable odor. It also has a high penetration force on the skin. For children with delicate skin or sensitive skin, the negative impact is not to mention And its effective time can only be maintained for 2 to 3 hours. All in all, the problem of DEET makes people feel uneasy. Therefore, in recent years, essential oils have been used by industry as mosquito repellent ingredients.

However, essential oils are easy to volatilize, so that users often need to spray the anti-mosquito liquid on the skin, which is not convenient to use. Furthermore, in addition to the need for anti-mosquitoes, users also often have the need for sterilization. In order to achieve the sterilization and disinfection effect, the messenger needs to bring another bottle of sterilant on the body to use it.

Therefore, how to provide an anti-mosquito bactericide that can achieve the dual effects of anti-mosquito and sterilization at the same time with a new formula, thereby improving the use and functionality of the product, is indeed one of the current important issues.
