Abstract

We investigated the effects of ethanol on solubilization of L-menthol solution. L-menthol solution was prepared by addition of PEG-40 Hydrogenated Castor Oil and PEG-60 Hydrogenated Castor Oil as nonionic surfactant. Ethanol was added in the solution to investigate effects of ethanol concentration on solubilization. We measured physical properties such as particle size and surface tension. The particle size and the surface tension became smaller with the increase of ethanol concentration.

본 연구에서 L-menthol 용액의 가용화에 미치는 에탄올의 영향을 연구하였다. L-menthol 용액은 1 mM L-menthol 수용액에 비이온 계면활성제인 PEG-40 Hydrogenated Castor Oil과 PEG-60 Hydrogenated Castor Oil을 가한 후, 에탄올의 농도를 변화시키면서 첨가하여 제조하였다. 제조한 용액의 입자크기와 표면장력을 측정하여 가용화에 미치는 에탄올의 영향에 대해 알아보았다. 에탄올의 함량이 증가할수록 입자크기와 표면장력이 감소하는 것을 확인하였다.
