Abstract
Physicochemical properties, such as, density, viscosity, surface tension, friccohesity for oil-in-water nanoemulsions (NEs) formed by castor (CO), olive (OO) and linseed oils (LO), respectively, with cellulose acetate propionate (CAP), cellulose acetate butyrate (CAB) and tween 80 (Tw80) are reported at various temperatures ranging from 293.15K to 313.15K. The aqueous solutions of the non-ionic surfactants used are CAP, CAB and Tw80 along with co-surfactants ethyl alcohol, ethyl acetate, ethylene glycol and Tw40. Surface tension, viscosity and friccohesity data were obtained from density, pendant drop number and viscous flow time. The surface tension value is used to calculate surface excess concentration and area per molecule. Particle size and activation energy were calculated from viscosity. The parameters viscosity, surface tension, friccohesity, particle size, surface excess concentration and activation energy were regressed for their limiting values. Overall, this manuscript focuses on the effect of temperature, structure of oil and surfactant on the formulation, properties and stability of NEs.
