Keywords:
organic Thai herbal mosquito repellent essential oil, viscosity, evaporation rateAbstract
The objective of this research is to study the properties of flammable viscosity and evaporation rate of organic Thai herbal mosquito repellent essential oils to provide information on the development of quality and chemical composition in the use of mosquito repellents in the adult stage. This organic Thai herbal mosquito repellent essential oil was previously developed for the elimination of mosquito larvae. The test was performed using 3 types of mosquito repellent devices, including a fan that was installed to distribute mosquito repellent devices; household mosquito repellents; household mosquito repellents; and mosquito repellent sprayers. A comparative test of the properties of organic Thai herbal mosquito repellent essential oil with mosquito repellent essential oils used with household mosquito repellents is currently available. From the flammable properties test, it was found that organic Thai herbal mosquito repellent essential oil has a viscosity of 18.07 s and has a flash point of 90 ℃, has a fire point of 95 ℃, and mosquito repellent essential oils used with household mosquito repellents have a viscosity of 6.38 s and has a flash point of 84 ℃, has a fire point at 88 ℃. For testing in the fan that is installed to distribute mosquito repellent devices and household mosquito repellents, it was found that organic Thai herbal mosquito repellent essential oil has an average evaporation rate of 0.034 ml/hr and mosquito repellent essential oils used with household mosquito repellents have an average evaporation rate of 0.225 ml/hr. For testing household mosquito repellents, it was found that organic Thai herbal mosquito repellent essential oil had an average evaporation rate of 0.0854 ml/hr and mosquito repellent essential oils used with household mosquito repellents had an average evaporation rate of 0.2118 ml/hr. It was tested in a mosquito repellent sprayer at the mixing ratio of organic Thai herbal mosquito repellent essential oil with clean water, 20 ml to 1 l. It has the best aerosol capability and can be sprayed at a distance of 5 meters. The usage rate for aerosol is 226.24 ml/min. This data can be used to develop organic Thai herbal mosquito repellent essential oils that are effective and suitable for repelling mosquitoes in the future.
