“…However, despite the potential benefits of mixed surfactants, there are also several challenges associated with their use. For example, mixed surfactants can be difficult to synthesize, stabilize, and use effectively in various processes as they can form crystalline precipitates in aqueous solutions. − In addition, there are often trade-offs between the different properties of mixed surfactants and blends compositions, making it challenging to optimize their use for different applications. , Therefore, it is important to carefully consider the potential benefits and challenges of mixed surfactants when exploring their use in various applications.…”

There is a large body of literature on the use of mixed surfactants; however, to the best of the authors' knowledge, no studies have been reported in the literature on the foaming properties of amino-acid surfactants (AASs) mixed with fatty alcohols.…”

Surfactants with amino-acid heads (AASs), namely N-lauroyl-L-alanine (C 12 -ALA), N-lauroyl-L-leucine (C 12 -LEU), and N-lauroyl-L phenylalanine (C 12 -PHE) were mixed with n-octanol (C 8 OH) and thoroughly investigated via surface tension and foamability experiments. Significant differences between the selected AAS were observed. Moreover, the results obtained under equilibrium and dynamic conditions were remarkably different in terms of surface activity. The surface tension measurements (equilibrium conditions) indicated that the C 12 -ALA/C 8 OH mixture exhibits the highest synergistic effect. For the C 12 -LEU/C 8 OH system, a moderate synergism was observed, while for C 12 -PHE/C 8 OH, the effect was antagonistic. In contrast, in foamability experiments (dynamic conditions), all of the studied AAS/C 8 OH mixtures exhibited a spectacular synergistic effect at a wide concentration range. The observed effect was referred to as convection-activated surface activity of AAS/C 8 OH mixtures. The obtained experimental results were interpreted on the molecular level via all-atom detail molecular dynamics simulations (MD). The observed phenomenon was connected with the hydrogen bond-mediated aggregate formation in the bulk solution. Such aggregates act as reservoirs of surfactant molecules for supplementation of the adsorption coverage at the freshly formed liquid/gas interface. Additionally, the differences between the specific AAS were explained via the interplay of AAS−AAS and AAS-C 8 OH hydrogen bond affinities. The presented results showed an interesting example of a foaming system in which the surface activity can be controlled in situ via convection. This finding also significantly expands the range of potentially interesting molecules that can be used as efficient foaming additives and impacts the current understanding of the role of hydrogen bonding in designing of tuneable surfactant mixtures.

“…It is well understood that oil type and salinity have a significant impact on the effectiveness of surfactants used in the industry. The authors of publications [ [11], [12]] studied the influence of oil type on the performance of mixed surfactants. The synergism of combinations of anionic, nonionic, and cationic surfactants in various types of oil was examined.…”

The goal of this research is to prepare novel amphiphilic graft copolymers (nonionic) based on hydrophilic poly (ethylene glycol) methyl ether (mPEG) and hydrophobic methyl methacrylate (MMA) at room temperature and pressure. To generate P(mPEG-g-MMA) grafts, poly (ethylene glycol) methyl ether (mPEG) was synthesized and grafted with varied ratios of methyl methacrylate (MMA) in the existence of benzoyl peroxide as an initiator utilizing a macro-free radical initiator procedure under the effect of heating in toluene. The research discussed in this paper looked at the possibility of using the synthesized graft copolymer P(mPEG-g-MMA) as a nonionic demulsifier in Petroleum Crude Oil Emulsions. The produced nonionic surfactants were assessed as water demulsifiers in oil emulsions that were noticeable at varying oil: water ratios at 60oC. According to the demulsifier chemical compositions as well as concentrations, the testing findings revealed that the dehydration rate of the prepared demulsifiers reached 100%. The optimal demulsifier dose was 300 ppm.
