The kind of lyotropic liquid crystal formed by Igepal CO series-H2O system is related to the number of EO group of the surfactants, but the concentration range is related to the minumin water content needed for the formation of lyotropic liquid crystal and the maximum water content solubilizated in lyotropic liquid crystal. n<10, lamellar liquid crystal forms and n>10, hexa nal liquid crystal forms. The minumin and maximum ratios of water to surfactant in amphiphtic bilayer of lamellar liquid crystal increase nonlinearly and linearly, respectively, with the EO group in lgepal CO series surfactant. There is no observable change for the formation of lamellar liquid crystal with addition of Igepal CO 710 in the Igepal CO 520 system. But the system shows the transformation of liquid crystal from hexa nal to lamellar when Igepal CO 520is added in the Igepal CO 710 system.
- Igepal CO series,
- Nonionic surfactant,
- Lamellar liquid crystal,
- Hexa nal liquid crystal
