Purpose : We will develop the distribution method of wide oil extract technology to develop repellent using this technology and study mosquito repellent persistence. Research design, data and methodology : A positive control group containing purified water, ethanol and picaridin was prepared, and the experimental control group was prepared in the same proportion as the positive control group, and 0.6% of broad oil was added. The results were summarized using the calculation method according to the avoidance effect and statistically tested by t-test using the excel statistics program. Results : Experiments on skin surface area and voice control of participants showed that men had 8.9% wider skin surface area than women, and voice control tests showed that women were bitten by mosquitoes five times more than men. Both the positive and the experimental control groups had a valid duration of up to three hours, but from the time of five hours, the positive control group had 77% and the experimental control had 90%, indicating a difference of 14.4% over the positive control group. Conclusions : The mosquito repellents developed in this study on the basis of safety and continuity are cost-effective in terms of mosquito repellent, and in addition fragrance, odor removal, perfume, ink, skin care and massage effect. .

Beauty is a feature which is feeling a perceptual pleasure about a human, concrete object or abstract object (Caki & Solmaz, 2013).The beauty salon industry further expanded in the 1990s (Lin, Lee, Lean, & Lan, 2018). The expansion and segmentation of cosmetics-related industries radically expanded due to an increase in income, diversification and differentiation of female consumers' needs, expansion of target groups for gender and age, increase in function and role of cosmetics, and population aging (Choi, Kwon, Kwon, & So, 2018).The cosmetic industry is an important and valuable global industry (Ramli, 2015).

Beauty-skin and beauty-fashion are now strong assets in the industrial and information society. In addition to traditional functions such as personal satisfaction,
