Organization of amphiphiles, part XIV: Studies on the interaction of a novel organic molecule with surfactant in solution and at air–water interface

“…CTAB monomers in bulk may on the other hand attract BP 4 monomers resulting thereby the reduction of its monomeric concentration; thus, BP 4 aggregates persuasively at higher concentration. Of late, such a decrease in monomeric concentration of surfactant due to the formation of hydrophobic complex leading to an increase in CMC of surface active molecule has been reported from our laboratory [43,44]. A similar phenomenon is observed in the case of TX-100 due its interaction with polyoxyethylene group present in the nonionic monomeric surfactant resulting in the decrease of monomeric concentration of BP 4 and hence the CMC of the BP 4 increases.…”

Conformational alterations induced by novel green 16-E2-16 gemini surfactant in xanthine oxidase: Biophysical insights from tensiometry, spectroscopy, microscopy and molecular modeling

“…The Gibbs free energy change of micellization and adsorption were evaluated by employing Eq. (4) and (5) [50,51]:…”

Regulation of chicken egg lysozyme functional properties by interaction with 5-methylresorcinol

“…This allows calculation of the surface per molecule from the adsorption density at the air/solution inter face [10] using the Gibbs equation,…”

“…Here, for comparison, the values of the corresponding quantities for some typical ionogenic (CTAB and DDS) [10] and nonionogenic surfactants [11,12] are also listed.…”

“…This suggests the dominance of the contribution from the formation of hydrogen bonds between the hydroxyl CTAB stands for cetyl ammonium bromide [10]; DDS, sodium dodecylsulfate at temperature of 30°C [10]; HBA (EO) 9-40 , ethoxylated hydroxuinone bis lauryl alcohols [11]; NP (7 30), nonylphenol polyoxiethylene ethers and TNP (7 30), trimeric nonylphenol polyoxi ethylenes [12].…”
