Physicochemical study of robust oil-in-water nanoemulsions with CTAB, SDS, and Tw20 at 293.15, 303.15 and 313.15 K

Abstract

Oil-in-water nanoemulsions (NEs) formulated using linseed oil (LO), olive oil (OO), and castor oil (CO) with cetyltrimethylammonium bromide (CTAB), sodium lauryl sulfate (SDS), and Tween20 (Tw20) as surfactants and cellulose acetate propionate (CAP) and cellulose acetate butyrate (CAB) as stabilizers are studied and their physiochemical properties such as density (ρ), sound velocity (u), and refractive index (nD) are reported at temperature T = 298.15, 303.15 and 313.15 K. The isentropic compressibility deviation (Δκs) and relative deviation in isentropic compressibility (Δκs/0κs), acoustic impedance (Z) and speed of light (VL) have been calculated using the values of the experimental the ρ, u and, nD value. Hydrophilic-hydrophobic interactions (HI-HbI), solute-solvent interactions (SLS0I) and other intermolecular interactions (IMIs) are correlated with the thermodynamic properties.
