Abstract

In this study, we have investigated the stability of sunscreens based on the solubility of organic UV absorbers in the oil and sun protection efficacy of the products composed of a combination of organic UV absorbers to develop more stable and efficient sunscreen products. Results showed that the solubility of the organic UV absorber and stability were varied depending on the type, storage conditions and concentration of oil. It was also observed from the products in the emulsion type. Various UV absorbances were determined to the products composed of the combination of organic UV absorbers. In some combinations, a synergistic effect was observed to make an increase in absorbance compared to a single component. In other cases, specific synergistic effect was displayed only when combined with the particular component. In addition, the storage condition also affected the sunscreen efficacy. In conclusion, this study confirmed that there are various factors which could affect the UV-blocking efficiency of sunscreen products.

본 연구에서는 유기 자외선 흡수제와 오일들 간의 용해도에 따른 자외선 차단제의 안정성과 유기 자외선 흡수제의 조합에 따른 이들의 자외선 차단 효율 변화를 조사하여 보다 안정하고 효율이 높은 자외선 차단제품 개발에 도움이 되고자 하였다. 그 결과 오일의 종류, 농도 그리고 보관 조건에 따라서 유기 자외선 흡수제의 용해도 및 안정성이 다양하게 관찰되었으며, 이러한 현상은 에멀젼상에서도 자외선 차단지수에 영향을 나타냄을 확인하였다. 또한 유기 자외선 흡수제의 조합에 따라 다양한 자외선 흡광도가 측정되었으며, 조합 시 각각의 자체 흡광도보다 높은 시너지 효과를 나타내는 성분이 있었고, 특정 성분과의 조합 시에만 시너지 효과가 나타나는 경우도 있었다. 보관 조건에 따라서도 자외선 흡광도는 상이하게 측정되어, 자외선 차단 효율에 영향을 나타내는 다양한 변수가 있음을 확인할 수 있었다.
