Abstract:The present work deals with the physiochemical properties of polyoxyethylene sorbitan fatty acid esters (polysorbates), which are commonly known under the trade name Tween. Thermodynamics of micellization and adsorption at air-water interface for these nonionic surfactants solutions have been studied over a broad range of temperature. As the temperature of the surfactant solutions increases, the surface tension decreases whereas the critical micelle concentration (CMC) of each surfactant solution initially dec… Show more
“…The increase in temperature distorts the structured water contiguous to the hydrophobic group, which leads to a shifting of the monomers–micelle equilibrium in favour of the monomer and promotes micellization at a higher concentration of surfactant. 30 The CMC values of the soap-nut surfactant were found to be 9.3 mM at 298 K, 9.8 mM at 313 K, 10.3 mM at 323 K, 10.8 mM at 333 K and 11.3 mM at 348 K.…”
The present study deals with the synthesis, characterization, physical and thermodynamic properties of a novel anionic surfactant derived from Sapindus laurifolius for its potential application against conventional non-biodegradable surfactants.
