Ionic liquids (ILs) are a topic of scientific interest for researchers and have attracted attention in many areas of modern science since the mid-1990s . For last two decade, ILs have been used as solvents or materials, or both, in many applications, including chemical processes, separation,  waste management, surfactant technology and capture  of gases due to their exceptional properties consisting of the combination of “green” properties with tunable physicochemical and biological properties. Recently, focus has shifted to more environmentally acceptable second- and third generation ILs comprising biocompatible cations (e.g., cholinium salts) and anions, such as amines and amino acids. A wide range of such ILs have been derived from readily available renewable resources and used in various industrial applications. Compared with first-generation ILs, the use of second- and third generation ILs provides better physical, chemical, and biological properties, and they are also attractive from both an environmental and an economic viewpoint. The knowledge on synthesis, purification and characterization of ionic liquids is important prior of utilizing ionic liquids for any applications. Among the different applications, ILs have been used significantly in oil industries due to their promising environmental and technological benefits of low volatility, low toxicity, high surface activity and thermal stability. Furthermore, the self‐assembling properties of amphiphilic surface active ILs (SAILs) have provided superior surface activity and appeared to form supramolecular nano- to giant- aggregates viz., micelles, vesicles, wormlike micelles and multi-layered vesicles. Considering all these points SAIL particularly 2^nd and 3^rd generation ILs derived from renewable bioresources can be used as a potential alternative of chemical dispersants including COREXIT, which is used for major the marine oil spill remediation.
