It is generally believed that asphaltenes adsorbed at oil/ Asphaltenes water interface can form a protective layer to stabilize the water-in-oil or oil-in-water emulsions. In this work, Adsorption kinetics the eﬀects of asphaltene concentration and temperature on the dynamic interfacial tension (IFT) of oil (i.e., Dynamic interfacial tension toluene)/water interface were systematically investigated using a pendent drop shape method.
