Abstract: We found it possible to form the lamellar liquid crystal using alcohol with short chains as a cosurfactant in SDS/CnOH/H2O systems,the stability of the lamellar liquid crystal increased with the chain length of alcohol.The increase of interlayer spacing d with the chain length of alcohol was related to the d0 value and the penetration of solvent in the lamellar liquid crystal.

Key words: surfactant, low angle X-ray diffraction, lamellar liquid crystal
