Abstract

Abstract:

With increasing of n in CnH2n+1 OH, the lamellar liquid crystal region increases and W/O region moves upward in the three components phase diagram, and the maximum water content (molar fraction) solubilized in W/O region is constant but the molar ratio of CnH2m+1 OH/Igepal 520 decreases at maximum water content. The chain length of CnH2n+1 OH is n＞8 in the lamellar liquid crystal and n ＞10 in the W/O region.

Key words: Igepal CO 520, Microemulsicn, Solubilization, Lainellar liquid crystal
