  • As research results showed that ozonated olive oil has excellent therapeutic effects on skin diseases, attempts were made to develop cosmetics manufacturing technology using ozone. Ozone is harmful to the human body, so a separate facility must be prepared to manufacture ozonated olive oil as a cosmetic raw material. The manufacturing device developed in this study was designed as an optimized process for manufacturing cosmetics while ensuring the safety of workers involved in production. To verify the ozonated olive oil produced from the implemented device, a toxicity test was conducted on animals. After applying ozonated oil (high concentration) to the rabbit's back for 24 hours, mortality, general symptoms and symptoms were measured. A skin irritation evaluation was performed. As a result of the experiment, as a result of evaluating the test substance treatment area after a certain period of time, it was confirmed that no skin irritation was observed in all animals, confirming the safety of the ozonated oil production process and the safety of the product.

  • There are many effective parameters to high concentration ozone generation. These parameters became very important elements should be considered before designing ozone generator. After designing, there are many peripheral parameters to greatly affect to high concentration ozone generation also. In this study, of many effective peripheral parameters on high concentration ozone generation, the effects of flow rate of inlet oxygen gas and some kinds of additional gases on ozone concentration were investigated As a result, when inlet oxygen gas was introduced at the range of 0.75[LPM]~2.00[LPM] the highest ozone concentration of 71145[ppm] was obtained at 1.25[LPM]. When the additional nitrogen gas was mixed to oxygen gas at the range of 0.0[vol%]~6.4[vol%] the highest ozone concentration of 73135[ppm] was obtained at 0.8[vol%] of nitrogen gas. This showed 3[%] increasing compared to the case of pure oxygen gas inlet. When the additional argon gas was mixed to oxygen gas at the range of 0.0[vol%]~6.4[vol%] the highest concentration of 67288[ppm]was obtained at 0.8[vol%]of argon gas. This is decreased value compared to that of introducing the pure oxygen.
