PRODUCTION OF LIQUID SOAP USING LEMONGRASS AS FRAGRANCE

ABSTRACT

Lemon grass (Cymbogon citratus) is an abundant, locally available plant. In this work, essential oil was extracted from it using solvent extraction method.  In this work two methods of extraction was used, solvent extraction and enfleurage methods were used to extract essential oil from lemongrass. Solvent extraction method yielded 2.08% and effleurage method yielded 1.96% essential oil respectively. From the analysis solvent extraction gave the highest yield because of the less exposure to air and heat and this conform the literature value. Liquid soap was produced using the essential oil and it was found to have a strong, long-lasting, pleasant smell.
