ABSTRACT

The seed oil of mango (Magniferaindica)was extracted by soxhlet extraction method using n-hexane as solvent and its chemical and physical properties were evaluated. The chemical parameters investigated include: saponification value (SV), iodine value (IV), peroxide value (PV) and Acid value (%AV). These were found to be85.3∓0.05mgKOH/g, 39.5∓0.10g I2/100gand 4.4mEq/kg and 2.4∓0.01mgKOH/g, respectively. The physical parameters evaluated include: percentage yield (10.21%), relative density (0.87), refractive index (1.4784) and moisture content (12.5%). Soap was then formulated using the oil and the properties of the product were evaluated. From the results, it was found that the products compared favorably to similar products sold in the market in terms of pH, colour, percentage alkali and solubility in water.
