Permethrin is one of the most common active ingredients in mosquito repellents. It is so commonly utilized to spray textiles and clothing repelling insects, in particular, mosquito, in order to avoid the victor-borne disease spreading through human society. In this article, our research team is, at first, to take research on two products, namely, Permethrin-based Mosquito Repellent Spray in aerosol version and water emulsion version respectively provided
by Hansk New Materials Holdings Ltd., Hong Kong and identify which one is better anti-mosquito efficacy and longer durability. Then, the research team further prepares the test products: Permethrin-based Mosquito Repellent Sprays for textiles and clothing with three different recipes (with different permethrin content). We conduct experiments and testing to evaluate the functionality of each recipe. We also investigate the anti-mosquito efficacy of the textiles and clothing sprayed with such kinds of permethrin-based Mosquito Repellent Sprays respectively.
