초록

신규 자외선차단제로 개발된 methoxycinnamidopropyl polysilsesquioxane은 유기-무기 혼성 구조의 고분자 입자로, 본 연구진은 이미 신규 자외선차단제에 대한 제조방법, 물리적 특성 및 자외선차단 효과에 대해 보고한 바 있다. 본 연구에서는 기존의 대표적인 유기 자외선차단제인 ethylhexyl methoxycinnamate (EHMC)와 동일한 기능기를 갖는 methoxycinnamidopropyl polysilsesquioxane의 광화학적 특성과 자외선에 대한 광안정성을 평가하였다. 또한, 자외선 흡광도와 형광의 상관관계를 이용하여, 광안정성을 향상시킬 수 있는 광안정화제에 대하여 연구하였다. Methoxycinnamidopropyl polysilsesquioxane은 광화학적으로 EHMC와 유사한 특성을 보였으며, octocrylene, ethylhexyl methoxycrylene 및 bis-ethylhexyloxyphenol methoxyphenyl triazine이 우수한 광안정화제로 확인되었다.

The new sunscreen agent, methoxycinnamidopropyl polysilsesquioxane, is manufactured as polymeric particles with an organic/inorganic hybrid composition. We have already reported the manufacturing method, physical properties, and sunprotection effects of methoxycinnamidopropyl polysilsesquioxane. In this study, we evaluated the photochemical properties and photostabilities of methoxycinnamidopropyl polysilsesquioxane that has the same functional group as a typical organic sunscreen agent, ethylhexyl methoxycinnamate (EHMC). Using the correlation of UV absorbance and fluorescence, we studied photostabilizers to enhance the photostability of methoxycinnamidopropyl polysilsesquioxane. Finally, we confirmed that octocrylene, ethylhexyl methoxycrylene, and bis-ethylhexyloxyphenol methoxyphenyl triazine were good photostabilizers for methoxycinnamidopropyl polysilsesquioxane.
