“…The interaction between NaSal and surfactants leads to a change in micellization properties of the latter [14,15]. This can be justified by the occurrence of the screening effect due to an increase in the ionic strength -the salicylate anion decreases the electrostatic repulsion between surfactant's head-groups-favoring the micelle formation and forming mixed micelles, once the aromatic ring interacts with the hydrophobic tails of surfactants [16][17].…”

“…Environmental conditions such as concentration, temperature, pH play an important role in controlling the aggregation behavior of various types of surfactants. Addition of co-solvents (alcohols, amines) plays an important role in detergency by increasing its (surfactant) performance [42,43]. Anita D, Mudawadkar and T. J. Patil after doing conductometric measurements on SDS in the presence of urea and acetamide in aqueous medium revealed that on increasing temperature, CMC increases, free energy of micellization (∆𝐺 𝑚 °) and enthalpy of micellization (∆𝐻 𝑚 °) becomes more negative whereas entropy of micellization (∆𝑆 𝑚 °)…”

Surfactants are the important class of amphiphilic species, which consists of both hydrophilic as well as hydrophobic part. They are characterized by some important properties like critical micelle concentration (CMC), charge, hydrophile-lypophile balance (HLB), aggregation, and chemical structure, which make them good emulsifying, dispersing and foaming agents. Presently, the global demand of the surfactants is on the peak due to their increased applications in detergents, paints, food emulsion, biotechnological processes, biosciences, pharmaceuticals, cosmetic products, etc. In order to prevent Corona pandemic disease, WHO and other regulatory authorities have recommended frequent use of soaps and sanitizers that makes surfactants an important class of species to be explored more in terms of their applications.

“…In the presence of ionic surfactants, co‐surfactants are added in the system of oil and water that plays the role of decreasing the repulsive forces between the charged hydrophilic parts of the surfactant molecules . Co‐surfactants of medium/higher chain length alcohols are more effective in increasing the viscosity of surfactant solution …”

Mixed surfactant systems have gained significant importance in the development of fracturing fluid due to polymorphism of self-assembly structures that have combined properties of the surfactants in the mixture. In this article, a comparative study on the phase behavior and viscoelastic properties of mixed surfactant based fluids, prepared from Tween 801NaOA/2-ethyl hexanol/clove oil/water and Tween 201NaOA/2-ethyl hexanol/clove oil/water quaternary system is investigated in details. The viscoelastic surfactant (VES) based fluids prepared from the former system offered superior rheological properties than the latter system. The addition of 0.1% NaOH and 500 ppm ZnO nano-particles in the VES fluids presented enhanced viscoelastic properties as concluded by static and dynamic rheological tests. Miscibility test indicated the miscibility of the VES fluids with water, unlike in the presence of diesel oil and satisfactory proppant suspension capabilities were exhibited by the developed fluids.Legend: A, water; B, (2-ethyl hexanol1water); C, (0.05% NaOH 1 2-ethyl hexanol 1 water); D, 0.1% NaOH 1 2-ethyl hexanol 1 water.
