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.

Objectives : Many people use natural soap instead of commercially available bar type general soap for skin care. They tend to prefer cp (cold process) type soaps that go through a sufficient maturation process in formulation. The purpose of this study was to investigate the efficacy of PCPS (placenta cp soap). Methods : The researcher selected 36 subjects, 28 as the experimental group and 8 as the control group. I asked participants to wash their face twice a day in the morning and evening, and the period was set for 6 weeks. The researcher had the people who were selected as the control group use a commercially available foam cleanser, meanwhile the experimental group use PCPS. They performed a skin test before the start of the test, and the change status was continuously investigated after 2 weeks, 4 weeks, and 6 weeks after using the soap. Results : In the case of U zone oil and pores, there was a significant decrease and in the case of skin tone, there was a significant increase in the group of using PCPS. In T zone oil change, there was no significant effect in both the experimental group and the control group. Conclusion : In the case of PCPS, it is recommended to use it in the effect of reducing the size of pores and increasing skin tone, but it can reduce u-zone oil content.

수송용 바이오연료로써 바이오디젤의 보급 활성화에 따른 원료인 식물성 기름의 가격 상승 및 수급 불안정성 문제를 해결하고자 그동안 활용되지 않았던 폐유지를 바이오디젤 생산 원료로 사용하여 바이오디젤 생산 단가를 낮추고 원료의 수급 안정성도 확보하려는 시도가 이루어지고 있다. 폐유지의 경우 대부분 유리지방산 함량이 높아 염기 촉매를 적용하는 방법으로는 비누의 생성으로 전환이 힘들며 산 촉매를 적용하여 유리지방산을 에스테르화하는 공정을 필요로 한다. 에스테르화 반응에서는 반응 부산물로 물이 생성되며, 생성된 물은 바이오디젤 생산 반응을 저해하고 역반응을 유도하며 촉매의 활성을 감소시킨다. 본 연구에서는 고유리지방산 함량 오일의 에스테르화 반응에서 수분의 영향을 검토하였다. 산 촉매로 액상 촉매인 황산과 고체 산 촉매인 Amberlyst-15를 사용하였다. 초기 수분 함량이 0, 1, 2, 5, 10, 20%로 증가하였을 때, 지방산 메틸 에스테르 함량이 크게 감소하였으며, 1%의 수분 함량에서도 반응이 크게 저해받는 것으로 나타났다. 따라서 고유리지방산 함량 오일의 에스테르화 반응에서 수분에 의한 저해가 중요한 변수라는 것을 알 수 있다. Amberlyst-15는 황산보다 수분의 영향에 의해 지방산 메틸 에스테르 함량이 빠르게 감소하였다. 이는 다공성의 Amberlyst-15에서 생성된 물이 반응물질들이 active site에 접근하는 것을 방해하였기 때문인 것으로 생각된다. 황산을 사용하였을 경우에는 오일 대 메탄올 몰비를 1:3에서 1:6으로 증가시킴으로써 정반응 속도가 증가하여 수분에 대한 영향이 감소하는 현상이 나타났다. 에스테르화 반응 종료 12시간 후에 바이오디젤과 메탄올 내에 수분 함량을 분석한 결과 12%의 수분이 바이오디젤 층에 존재하며 88%의 수분은 메탄올 층에 존재하였다. 반응 중에 생성된 수분을 제거하기 위해, 에스테르화 반응 30분 후에 물을 포함하는 메탄올과 촉매 층을 새 메탄올과 촉매로 교환하는 2단계 반응을 수행함으로써 지방산 메틸 에스테르 함량을 향상시킬 수 있었다. 반응 초기에는 황산이 Amberlyst-15보다 높은 활성을 보였지만, 시간이 지날수록 두 촉매 사이의 에스테르화 성능 차이는 감소하였다. 따라서 2단계 에스테르화 반응이 수분의 저해작용을 줄이는 한 가지 대안으로 제안될 수 있다. 또한 에스테르화 반응에서 물의 저해 작용을 줄이기 위해 앞으로 투과증발막의 적용 또는 물에 저해작용을 받지 않는 구조의 촉매 사용을 검토할 필요가 있다.

Based on reaction time and substrate molar ratio, structured lipid (SL-corn) was produced at 1:2:2(corn oil/capric acid/CLA) and 4% immobilized lipase from Rhizomucor miehei (RM IM). Reaction was carried out for 24 hr at $55^{\circ}C$ in 1-L stirred-batch reactor. After reaction, 13.3 mol% capric acid and 8.9%, CLA were incorporated into corn oil. Iodine and saponification values of SL-corn were 68 and 202, respectively. Tocopherol content decreased after reaction (about 39%). SL-corn showed more yellowish color than corn oil (p<0.05). Reversed-phase HPLC indicated triacylglycerol species containing capric acid in SL-corn resulted in faster crystallization than that of corn oil.

Structured lipid (SL) was produced from soybean oil with molar ratio of 1：2：2 (soybean oil：capric acid：CLA) using Chirazyme L-2 lipase (4％ by weight of total substrates). The reaction was conducted for 24 hr at 55$^{\circ}C$ in a 1 L stirred-batch type reactor. SL-soybean oil contained 4.9 mol％ capric acid and 4.1 mol％ CLA, respectively. Iodine value of SL-soybean oil was reduced than that of soybean oil due to the incorporated capric acids. Tocopherol content in SL-soybean oil was 18.2 mg/l00 g. SL-soybean oil appeared more yellowish color than soybean oil. Reverse-phase HPLC showed that SL-triacylglycerol species containing capric acid consisted of about 12.6 area％.
