자외선 차단 제품에서의 유기흡수제 조합에 따른 자외선 차단지수 변화에 관한 연구

Abstract

I compounded the UV-filters by wavelength of maximum absorbance. As a result of measurement of maximum absorption curve(spectrum) by UV/VIS Spectrophotometer, the combination absorbs evenly UV-A and UV-B. As a result, in order Bis - Ethylhexyloxyphenol Methoxyphenyl Triazine and Benzophenone-3, Butyl Methoxydibenzoylmethaneand Ethlyhexyl Methoxycinnamate, Benzophenone-2 and Benzophenone-3 was well absorbed. Sunblock cream of Bis - Ethylhexyloxyphenol Methoxyphenyl Triazine and Benzophenone-3, Butyl Methoxydibenzoylmethaneand Ethlyhexyl Methoxycinnamate, Benzophenone-2 and Benzophenone-3 was manufactured and Maximum absorption wavelength was measured. According to the date, Bis - Ethylhexyloxyphenol Methoxyphenyl Triazine and Benzophenone-3's sunblock cream had the highest value. We could know the combinations were Bis - Ethylhexyloxyphenol Methoxyphenyl Triazine and Benzophenone-3 that absorbs well UV-A area and B area at the same time. However Bis - Ethylhexyloxyphenol Methoxyphenyl Triazine and Benzophenone-3 sunblock cream's value gradually lowered as time passes. Because of difference of solubility Bis - Ethylhexyloxyphenol Methoxyphenyl Triazine depending on oil type this phenomenon is appeard. More research is needed about this problem later.
