초록

정제된 시벅턴오일을 사용하여 자외선차단 크림을 제조하고, 자외선 흡수능 및 유화안정성을 최적화하기 위해 중심합 성계획모델 반응표면분석법(CCD-RSM)로 실험 조건을 설계하였다. 실험의 독립변수는 유화제 첨가량, 유화시간, 점증제 첨가량으로 설정하였고, 반응치로는 ESI, MDS, 290 nm에서의 흡광도로 설정 후 실험을 진행하였다. RSM 최적화를 통해 산출된 회귀방정식 계수의 F-value와 P-value을 통해 반응치에 가장 영향을 주는 주효과도와 교호효과도를 분석하였고 P-value를 통해 계수의 통계적 유의성을 평가하였다. 반응표면분석법을 통해 산출된 최적 유화조건은 유화제 첨가량(4.39 wt%), 유화시간(25.42 min) 및 점증제 첨가량(1.24 wt%)으로 산출되었고, 이때 반응치 값은 ESI (98.5%), MDS (322.9 nm), 그리고 UV 흡광도(2.73)이다. 산출된 최적 조건으로 실제 실험을 진행한 결과 평균 오차율은 ± 2.7% 로 측정되었다.

To improve the UV absorbance and emulsion stability of sunscreen creams prepared using refined seabuckton oil, experimental conditions were designed utilizing the central composite design model-response surface methodology (CCD-RSM). The amount of surfactant, emulsification time, and thickener amount were chosen as independent variables, and the experiment was carried out after the reaction values of ESI, MDS, and UV absorbance at 290 nm were determined. The main effect and interaction effect, which have the most influence on the response value, were analyzed through the F-value and P-value of the regression equation coefficient calculated through RSM, and the statistical significance of the coefficient was evaluated through the P-value. The optimal emulsification conditions using RSM were calculated as follows: amount of surfactant (4.39 wt%), emulsification time (25.42 min), and amount of thickener (1.24 wt%). At these conditions, the reaction value was calculated as ESI (98.5%), MDS (32.9 nm), and UV absorbance (2.73). As a result of conducting an actual experiment under the calculated optimal conditions, the average error rate was measured as ± 2.7%
