초록

천연물인 황금추출물과 천연유화제인 올리브 유화왁스를 사용하여 제조된 cosmeceuticals의 유화안정성 및 대장균에 대한 항균능력을 최적화하였다. 독립변수로는 황금추출물 첨가량과 올리브 유화왁스의 첨가량으로 설정하였으며, 반응치로는 제조한 cosmeceuticals의 유화안정도지수(ESI)와 대장균 억제직경을 설정하였다. CCD-RSM을 통하여 95% 신뢰구간 내에서 통계학적으로 합리적이며 신뢰성이 우수한 회귀방정식을 얻었다. 다중반응의 최적화를 통하여 유화안정도지수와 대장균 억제직경을 동시에 만족하는 최적 유화조건으로 황금추출물 첨가량은 3.7 wt%, 올리브 유화왁스의 첨가량은 2.7 wt%이었으며, 산출된 유화안정도지수와 대장균 억제직경의 예측값은 각각 97.9%와 9.7 mm로 나타났다. 최적 조건에서 실제 실험을 진행한 결과 유화안정도지수 및 대장균 억제직경은 각각 95.0%와 9.4 mm로 측정되어 다중반응에 의한 예측값과의 평균오차율은 3.2 ± 0.4%로 나타났다.

To optimize the emulsion stability and antibacterial activity against Escherichia coli (E. coli) of cosmeceuticals using Scutellaria baicalensis extracts and olive wax as natural emulsifiers, we conducted a study. The independent variables were the amounts of Scutellaria baicalensis extracts and olive wax added. The response variables included the emulsion stability index (ESI) of the cosmeceuticals product and the inhibition diameter against E. coli. Through central composite design-response surface methodology (CCD-RSM), we obtained a statistically significant and reliable regression equation within a 95% confidence interval. By optimizing multiple responses, we determined that the optimal emulsification conditions that satisfied both ESI and E. coli inhibition diameter were 3.7 wt% of Scutellaria baicalensis extracts and 2.7 wt% of olive wax. The predicted ESI and E. coli inhibition diameter were 97.9% and 9.7 mm, respectively. When actual experiments were conducted under the optimal conditions, the measured ESI and E. coli inhibition diameter were 95.0% and 9.4 mm, respectively, with an average error rate of 3.2 ± 0.4%.
