The effect of α-propylene glycol, glycol, and glycerin on the phase behavior of water-hexane-dodecylsulfonate-hexanol(as cosurfactant) system was investigated. These additivcs all increase the region of O/W type microemulsion, and the amount of solubilized hexane at the optimum ratio of hexanol/dodecylsulfonate, among them, α-propylene glycol is the best. Disscusion was given in four aspects:
1. Do these additives play any part on the interfacial adsorption?
2. Do they change the HLB value of the surfactant or the cosurfactant?
3. What effect do they have on liquid crystaline phase?
4. Do they change the solubility of the surfactant in the equeous solution?
