ABSTRACT
Emulsification of xylene was carried out using mixed surfactant system. HLB concept was used to select the right surfactant mixture. Variation in the stability of emulsion with respect to HLB was investigated by studying interaction between mixed surfactant. The interaction was quantified interms of interaction parameter β. Exact location and nature of the interaction was (hydrophilic / hydrophobic) studied by 1H NMR spectroscopy. Charge present on emulsion droplet was calculated by zetapotential measurement.
