Extraction and Utilization of Essential Oil from Neem Seeds in Toothpaste Formulation Aye Aye Mar Chaw Su Mon Mon Oo The present research work focused on the extraction of essential oil from neem seeds and its utilization in herbal toothpaste formulation. Firstly, the physico-chemical properties of neem seeds (Azadirachtaindica A. Juss) were determined and the essential oil was extracted from them by using solvent extraction process. Effect of particle size of neem seeds, extraction temperature and time, types of solvent such as n-hexane and ethanol on the yield percent of essential oil were investigated. The physico-chemical characteristics and fatty acid profile of extracted essential oil were also determined using American Oil Chemists’ Society (AOCS) official method and Gas Chromatography (GC). The extracted essential oil was utilized in toothpaste formulation. The characteristics such as pH, alkalinity, viscosity, density, lead content, arsenic content, foaming power and physical appearance of formulated herbal toothpastes were also determined and compared with commercial product. 2017 https://meral.edu.mm/records/6670
