초록

오존은 무색의 독성 가스로, 질소 산화물과 탄화수소가 태양 광선에 의해 광화학 산화 반응이 일어나면서 생성된다. 낮은 농도여도 호흡기 기관에 영향을 주고, 기침 또는 인체에 해롭다. 화장품 원료 중 질소 플라즈마에서 오존이 생성되는 것을 확인하였고, 1 day 후부터 오존의 농도가 낮아짐을 알 수 있었다. 반면 아르곤 가스로 발생된 오존 free 플라즈마는 오존이 검출되지 않았다. 따라서 오존 free 플라즈마를 활용하여 오존 free 화장품의 제조를 목표로 하였다. 효율적인 플라즈마 처리를 위해 non-sinking 법을 활용하여 층분리 미스트, 토너와 앰플에 주입하고, 안정도를 관찰하였다. 층분리 미스트에서 플라즈마의 주입 성공량이 두 제형보다 많았으나, 토너와 앰플에 비해 급격히 감소함을 확인할 수 있었다. 사용된 오존 free 플라즈마는 저온(4 ℃), RT (25 ℃), 고온(37 ℃, 50 ℃) 조건에서 층분리 미스트, 토너와 앰플의 안정도에 영향이 미치지 않는 것을 확인하였다. 따라서, 본 연구는 오존 free 플라즈마의 제형별 화장품 가능성과 안정성의 중요성을 시사하고 있다.

Ozone is a colorless, toxic gas that is produced when nitrogen oxides and hydrocarbons undergo a photochemical oxidation reaction in the sun's rays. Even at low concentrations, it affects the respiratory system, causing coughing and other harmful effects. It was confirmed that ozone was generated from nitrogen plasma among cosmetic raw materials, and it was found that the concentration of ozone decreased after 1 day. On the other hand, ozone was not detected in ozone-free plasma generated with argon gas. Therefore, we aimed to produce ozone-free cosmetics by utilizing ozone-free plasma. For efficient plasma processing, the non-sinking method was utilized to inject the plasma into layer separation mists, toners, and ampoules, and the stability was observed. It was found that the successful injection of plasma in the layer separation mist was higher than the other two formulations, but decreased sharply compared to the toner and ampoule. It was found that the ozone-free plasma used did not affect the stability of the layer separation mist, toner, and ampoule under low temperature (4 ℃), room temperature (25 ℃), and high temperature (37 ℃, 50 ℃) conditions. Therefore, this study suggests the importance of ozone-free plasma for cosmetic potential and stability of each formulation.
