EXTRACTION AND FORMULATION OF PERFUME FROM LEMONGRASS LEAVES

Abstract

Perfume extraction refers to the extraction of aromatic compounds from raw materials, using methods such as distillation, solvent extraction, expression or enfleurage. The extracts are either essential oils, absolutes, concretes, or butters, depending on the amount of waxes in the extracted product. Heat, chemical solvents, or exposure to oxygen in the extraction process denature the aromatic compounds, either changing their odour, character or rendering them odourless. In this work three methods, solvent extraction, hydro distillation and enfleurage methods were used to extract essential oil from lemongrass. Solvent extraction method yielded 2.08%, enfluerage method yielded 1.96% and hydro distillation methods yielded 0.95% essential oil respectively. From the analysis solvent extraction gave the highest yield because of the less exposure air and heat and this conform the literature value. The extracted essential oil was formulated into perfume using a fixative and carrier solvent.
