Objectives : Cleanser is the most basic tools used in daily skin care. I made a cold process soap using Castanea crenata inner shell (CCIS). I'd like to study the effect of face wash using CCIS cold process (CP) soap on the skin. Methods : The same water and towel were used at the same place in order to examine the skin change state immediately before and after washing face. The skin test was performed before and after 10 minutes washing the face in order to remove these external environmental factors, such as lifestyle, alcohol, tobacco, and stress etc. As a control group, the cases of washing with water and foam cleanser (F/C), which is a popular commercial product, were set. Three cases were compared and analyzed. Results : In the case of water washing, there was a significant decrease in oil (U-zone) but that was not good effect. In the case of F/C and CCIS washing, there were significant decrease in oil (T-zone), pores and pigmentation, but the significance was bigger in CCIS washing. In the case of pores, there was a significant decrease in all three cases. Conclusion : In the case of F/C and CCIS washing, it showed the effect of reducing T-zone oil, pores and pigmentation. But the significance was greater in CCIS case than in F/C case. CCIS cp soap is considered as a form of face wash that is suitable for skin care.

대두유에 율피의 용매분획별(에테르, 부탄올, 물) 추출물과 tocopherol, BHA를 각각 0.02% 첨가한 후 자동산화 및 가열 산화시 항산화효과를 비교하였다. 1. 자동산화시 과산화물가를 통한 항산화력 비교에서 $45^{\circ}C$에서 42일간 저장한 경우 부탄올추출물 > 에테르추출물 > 무첨가구 > BHA > 토코페롤 순으로 항산화력이 있었고, $60^{\circ}C$에서 32일간 저장한 경우에도 부탄올 추출물이 강한 항산화력을 보였으며, 에테르추출물은 무첨가구와 큰 차이가 없었다. 2. 가열산화의 경우 에테르추출물이 우수한 항산화력을 나타내었다. 3. 추출물의 용매별 항산화성분의 분석결과 에테르추출물에는 ellagic acid, quercetin, morin, naringenin, flavanol로서 주요성분은 ellagic acid이었다. 이들 성분의 총량은 에테르추출물 49.09%(w/w), 부탄올추출물 76.26%(w/w)로서 부탄올 추출물에 폴리페놀성분이 다량 함유되어있어 우수한 항산화효과에 영향을 미친 것으로 판단된다. 부탄올추출물에는 ellagic acid, naringenin, gallic acid, flavanol이 있었으며, 주요성분은 naringenin, gallic acid로서 이들 성분들이 항산화 효과에 영향을 미친 것으로 사료된다.
