본 연구에 사용된 비이온성 계면활성제는 1-O-oleoyl glycerol, 2-O-oleoyl-myo-inositol 및 methyl 2-O-oleoyl-α-D-glucopyranoside였다. 이들 3종류의 비이온성 계면활성제에 대한 용액성질과 가용화과정은 상평형에 의하여 관찰하였다. 그 결과 계면활성제/물 2성분계와 3wt.％계면활성제/물/cyclohexane 3성분계는 각각 온도에 의존하는 것으로 나타났다. 계면활성제/물/cyclohexane계에서 3상영역은 27℃∼32℃, 36℃∼45℃와 38℃∼52℃의 온도 범위에서 각각 나타났으며 3상영역의 부근에서 물 및 오일의 가용화가 최대가 되었다. 계면활성제/물계의 온도변화에 따른 상거동을 살펴 본 결과 1-O-oleoyl glycerol은 hexagonal 액정상이, 2-O-oleoyl-myo-inositol 및 methyl 2-O-oleoyl-α-D-glucopyranoside는 lamella형태의 액정상이 관찰되었다.

1-O-oleoyl glycerol, 2-O-oleoyl myo-inositol and methyl 2-O-oleoyl-α-D-glucopyranoside were used as surfactants in this study. The solution properties and solubilization process of those nonionic surfactants were examined by the phase equilibria. As a result of this study, we have found that phase behavior of two component systems of surfactants/H₂O/cyclohexane depends on temperature respectively. The three phase regions of three component systems appeared in the temperature range of 27℃∼32℃, 36℃∼45℃and 38℃∼52℃ and solubilization of water and oil was high in those three phase ranges, As the temperature was varied in the two component systems, liquid crystals of hexagonal were observed to in the case of 1-O-oleoyl glycerol, and liquid crystal of lamella types were observed in the case of 2-O-oleoyl myo-inositol and methyl 2-O-oleoyl-α-D-glucopyranoside.
