“…There is another class of novel surfactant identified by Menger and Littau in 1991, containing more than one hydrophilic group linked by a spacer (Figure ) . This spacer groups enhances the hydrophobic nature of the Gemini surfactants compared to the monomeric surfactants . The hydrophilic heads may be cationic, anionic and neutral or zwitter ionic in nature and the hydrophobic tail may be long or short in size.…”

Amphiphiles or surfactants are widely known for its reducing power of interfacial tension and extraordinary rheological properties. Among the various classes of surfactants gemini surfactants, biosurfactants and polymeric surfactants are remarkable and distinguishable among the others for their structural diversity and profitable usefulness. Primarily, the performance of any surfactant can be determined by HLB (Hydrophile Lipophile Balance) value, an empirical parameter. This review attempts to clarify some of the terminology used in literature by providing illustration of classification, features and diverse applications of different surfactants.

“…The used micellar catalysts can some times be easily recycled in the reaction. Micelles and other types of surfactant aggregates are effective catalysts for a wide range of organic reactions [22][23][24]. It has been already reported that reaction rates are affected by solubilization of reactants, changes in local concentrations due to compartmentalization of reaction media, and changes in medium properties [25].…”

Chromic acid oxidation of malonic acid in aqueous media has been investigated spectrophotometrically at 303 K. The product glyoxylic acid has been characterized by 13 C-NMR and FTIR spectroscopy. Three representative N-heteroaromatic nitrogen base promoters, 2-picolinic acid, 2,2 0 -bipyridine (bpy) and 1,10-phenanthroline, in combination with the anionic surfactant sodium dodecylsulfate (SDS) enhanced the rate of the oxidation reaction compared to the unpromoted reaction. 2,2 0 -Bipyridine produced the maximum rate enhancement of the three promoters used. The mechanism of the reaction has been proposed with the help of kinetic results and spectroscopic studies. The observed net enhancement of rate effects has been explained by considering the hydrophobic and electrostatic interaction between the surfactants and reactants. The SDS and bpy combination is suitable for malonic acid oxidation.

“…Biosurfactants have several advantages over chemically synthesized surfactants, which are lower toxicity, having specific functional groups with targeted actions, and more effective at extreme temperatures or pH values (Jiménez‐Peñalver et al, ). The commercial potential of biosurfactants is based on these advantages (Mao et al, ; Mondal et al, ; Vijayakumar and Saravanan, ). Being produced from renewable resources, biosurfactants facilitate sustainable development.…”

Determination of the distribution of sophorolipid (SL) congeners controls their self-assembly structures and therefore their employment as glycolipid biosurfactants in cosmetics, environmental remediation, and personal care applications. The compatibility of 3-hydroxypicolinic acid (HPA) as a matrix for compositional analysis of SL using palm olein as carbon energy source by matrix-assisted laser desorption ionization time of flight mass spectrometry (MALDI-TOF MS) analysis under positive and negative ion modes is studied in this work. Examination in positive ion mode revealed ions that were not detected in negative ion mode. Molecular ions produced using HPA matrix were lactonic Glc-Glc-1 0 ,4 00 -C18:1, anionic Glc-Glc-1 0 -C18:1, lactonic monoacetate of Glc-Glc-1 0 ,4 00 -C18:1, and anionic monoacetate Glc-Glc-1 0 -C18:1 and the anionic diacetate of Glc-Glc-1 0 -C18:1. We also detected Glc-Glc-1 0 -C18:0, GlcOAc-Glc-1 0 -C18:0, GlcOAc-GlcOAc-1 0 ,4 00 -C18:0, and GlcOAc-GlcOAc-1 0 -C18:0 which are congeners of SL with stearic acid moieties. 3-HPA has been established to be the superior matrix for elucidation of structures for SL using MALDI-TOF MS.
