Small droplets of oil are finely dispersed in the water phase (continuous phase) to create this oil-in-water emulsion. Increased temperature was found to cause instability of emultion. An oil-in-water emulsion is a mixture in which an oily phase is dispersed in water or another aqueous liquid. There is a correlation between emulsion stability and physicochemical properties of crude oil which showed that higher asphaltene content in the crude oil would form more stable emultion. The resin and wax do not form stale emulsion either aloneor together. The result show that the interfacial active component that stabilize emulsion is asphaltene. The study investigated the influence of asphaltene, resin and wax on emultion stability if it`s present in the crude oil alone, together or combination one of the others. ![]() The emulsion stability was studied by measuring the volume of water or oil phase separated in variation with time, water hold up, and the heights of the sedimenting/coalescing interfaces during the separation at various temperatures. The stability of water-in-oil emulsion of some Malaysian crude oils was studied with particular emphasis on effect of interfacial active components existed in the crude oil, i.e. Thus, the results presented in this study showed that the new formulation can potentially replace the conventional dispersant used for marine oil spill remediation. The VCOE products have high viscosities in each concentration of emulsifier and. The toxicity study against Gram-positive and -negative bacteria depicts the “practically harmless” nature of the developed formulation. VCOE was successfully formulated in the mixture of VCO-water ratio of 80:20. The developed formulation worked effectively as a crude oil emulsifier and formed a stable crude oil emulsion. The toxicity of the newly developed formulation was evaluated to confirm their safe employment in sea water. In this study, the formulation comprised of choline based ionic liquid, choline laurate () and a biosurfactant, lactonic sophorolipids (LS) were used as a crude oil emulsifier. Therefore, to overcome this problem, the employment of environmentally benign dispersants is one of the effective conceivable approach. However, the toxicity related with these dispersants confined its application in marine environment. Chemical dispersants is one of the globally accepted remediation technique used for marine oil spill. ![]()
