Physicochemical Properties of Mixed Surfactants System at Different Temperatures

Physicochemical Properties of Mixed Surfactants System at Different Temperatures

The significance of the physicochemical properties of cationic surfactant dodecyltrimethylammonium
bromide (DTAB) and anionic surfactant sodiumdodecyl sulfate (SDS) mixed surfactants systems in
the aqueous solvent medium were studied. Thus, the physicochemical properties are showed a
change of the molecular structural activities, which depends on several factors such as solvent, pH,
temperature, and presence of other molecules like drug, dye, protein, metal, salt, and so on. The ratio
of surfactants is the main factor for the formation of kinetically and thermodynamically stable
formulation. The physicochemical properties (PCPs) have been indicated the solute-solvent
interacting activities. An increasing the concentration of surfactants the viscosity, density, conductivity,
refractive index, and dipole moment increase while the surface tension, hydrodynamic volume,
apparent volume decreases at the particular concentration and after that, it’s either increase or
decrease its dependence on the environment as well as the orientation of the molecules.
