Planning to prepare an emulsion of natural oil in water. In this regard need to emulsify the same using surfactant. What % of surfactant should be used?
If you are preparing oil in water emulsion then u can choose the emulsifier having the HLB value in range of 7-15 (for eg TWEEN 80) or if it is water in oil emulsion then you should select the emulsifier of HLB 1- 7 (for eg SPAN 80).
Once you select the emulsifier, then you should carry out the study at different oil to surfactant ratios and optimize the ratio based upon your size and interfacial tension analysis.
I am in need of research materials on how to tackle a research on the "evaluation of Surfactant and it's concentration in emulsion treatment". I will be grateful if any assistance is rendered
