Problems solved by technology

However, in actual application, it was found that the toilet water prepared with this composition does not have a very satisfactory mosquito repellent persistence. The repellent effect of this product on Aedes albopictus meets Class B, and the effective mosquito repellent time reaches 4 hours
[0006] In addition, most of the cosmetics with mosquito repellent effect in the prior art are liquids for spraying, such as toilet water, etc., which will increase the liquid retention on the body surface when the body sweats, and although some mosquito repellent ingredients are natural plant extracts, due to It is in full contact with human skin, and a large amount of it remains on the surface of human skin for a long time, which will cause certain damage to the skin
In addition, experiments and practical applications show that the existing natural plant-derived mosquito repellent liquid is usually darker in color, and if it is sprayed on some clothes, it will be difficult to clean and pollute the clothes. For example, the mosquito repellent composition disclosed in CN101884608A is itself a Brown liquid, the precautions on the commercially available packaging are clearly marked "do not spray on light-colored clothing, avoid coloring"
