Abstract

In this study, we investigated the effect on the increase of In vitro skin permeation experiments and In-vivo skin whitening efficacy using a O/W nanoemulsion produced via PIC(Phase Inversion Composition) with 1,3-di(pentyloxyl)benzene. skin permeation experiments of RS-nanoemulsion formulated with selected condition was evaluated compared to mineral oil containing 1,3-di(pentyloxyl)benzene and normal O/W type RS-emulsion. Compared to mineral oil with 1,3-di(pentyloxyl)benzene and RS-emulsion. RS-Nanoemulsion has a statistically significant high percutaneous absorption in terms of index substance, which is 1,3-di(pentyloxyl)benzene. In vivo test were prepared in the system of O/W cream containing RS-nanoemulsion. There was no adverse reactions in both samples. After 8 weeks, the subjects was evaluated by a dermatologist's scoring and Chromameter. In conclusion, the testing product showed statistically improvement (p<0.05) compared to the controlled product and proved its whitening efficacy.

본 연구에서는 피부미백제로 개발된 레조시놀다이펜틸에터[1,3-di(pentyloxyl)benzene]를 함유하여 조성 상전이 방법(Phase Inversion Composition, PIC)방법으로 제조된 RS-Nanoemulsion의 경피 흡수 및 피부 미백 효능효과에 대해서 연구하였다. 지표성분인 1,3-di(pentyloxyl)benzene를 mineral oil에 용해한 대조시료와 일반 O/W유화법으로 제조된 RS-emulsion시료를 비교 대상으로 인체 피부에 대한 경피 흡수시험을 수행하였다. 시험결과, RS-Nanoemulsion 시료는 지표성분인 1,3-di(pentyloxyl) benzene를 mineral oil에 용해한 대조시료와 RS-emulsion 시료에 비해 통계적으로 유의하게 높은 지표성분 경피 투과율을 나타내었다. RS-Nanoemulsion을 O/W크림에 함유하여 만든 크림 제형의 피부임상시험을 통하여 그 유효성을 평가하고자 하였으며, 상기 시험결과 시험제품과 대조제품 모두 8주간의 시험기간에 특별한 이상반응이 관찰되지 않아 안전한 제품으로 확인되었고, 사용 8주 후 평가에서 대조제품 사용에 비해 시험제품이 통계적으로 유의한 수준으로 피부미백에 도움을 주는 효과가 있는 것을 확인하였다.
