Ishwar T. Gawali ^[2] | Ghayas. A. Usmani ^[2]

Abstract: Gemini or dimeric surfactants can be viewed as two conventional surfactants connected via a spacer at the level of the polar head groups. Various Physico-chemical properties of synthesized glycerol based non-ionic gemini surfactant synthesized by using 1, 2, 7, 8 -diepoxideoctane as spacer has been studied. The surface active properties such as surface tension, critical micelle concentration and effectiveness were determined. The value of surface tension and critical micelle concentration were found to be 30.5mN/m and 0.005mMol/L respectively. The foam production and stability was studied by measuring the volume of foam produced after 30 second and 300 second by varying concentration. The result shows that foaming power and stability is quite low. The investigation showed that synthesized surfactant has good emulsifying power as it promotes emulsion formation at both low and high concentration. The wetting power of synthesized surfactant is quite low. The dispersion power of synthesized non-ionic gemini surfactant was found to be 35 %. The synthesized surfactant can be used as emulsifier and dispersing agent.
