In this study, Kaempferol (0.2 m/mmol kg���1) dispersed cationic surfactants micelles were prepared as a function of alkyltrimethylammonium bromide (CnTAB) hydrophobicity (C = 12 to C = 16). The dispersion study of Kaempferol in different CnTAB: dodecyltrimethylammonium bromide (C = 12), tetradecyltrimethylammonium bromide (C = 14) and hexadecyltrimethylammonium bromide (C = 16) was studied with the physico-chemical properties: density, sound velocity, viscosity, surface tension, isentropic compressibility, acoustic impedance, surface excess concentration, area occupied per molecule and thermodynamic parameters, Gibbs free energy, enthalpy, activation energy measurements at 298.15 K. These properties were measured with varying concentration of CnTAB from 0.0260 to 0.0305 mol kg���1 in the 10% (w/w) aqueous dimethyl sulfoxide solvent system. The variations in these measured properties have been inferred the Kaempferol dispersion stability via hydrophobic���hydrophilic, hydrophilic���hydrophilic, van der Waals and hydrogen bonding and other non-covalent interactions. |
