Physico-Chemical Analysis and Potentials of Onion Seed Oil for Soap Production
Subject area: Science,Engineering and Technology · Area of research: Applied Chemistry
Abstract
This study was carried out to determine the physic chemical properties and potentials of onion seed oil for soap production. Onion seed oil was extracted using soxhlet extraction. The result of the chemical analysis gave the percentage of (30.20%) with the density of 0.86g/cm3. The color of the oil was light green and chemical analysis of theoil reveals saponification value for onion oil is 211.54?0.05mg KOH/g. The iodine value for onion seed is 98.13?0.39g 12/100g. Acid value is 5.13?0.04mgKOH/g. The peroxide value is 2.75?0.25. Refractive index is 1.46?0.01 and free fatty acid value of this oil is 6.93?0.54. A simple cold-process alkali hydrolysis of the onion oil was used to produce a milky colored soap with a foam height of 60cm3 for onion soap. The chemical properties of the soap produced from the oil were total fatty matter (36.33%), total alkali (0.78%), percentage chlorine (0.48%) and pH (10.70) respectively. From the physic chemical analysis of the oil and the soap produced, it can be concluded that oil from onion seeds has the potential in the production of soap, perfumery and pharmaceuticals
