Physicochemical study of the edible oils is important parameters. Refractive indices Specific gravity and densities of the edible oils were measured. Abbe refract meter was use to determine refractive index. Density and Specific gravity were estimated by pycnometer. Specific refraction of the edible oils were calculated using Lorentz and Lorenz (L-L) and compare with ADJ, CDJ, GDJ’s formula. On comparisons it is observed that all the formulas of specific refraction, accepted for organic compounds are also in good agreements for edible oils.
