SYNTHESIS AND ANTIMICROBIAL EVALUATION OF DIFFERENT TYPES OF SOAP SAMPLES FROM JATROPHA OIL

Abstract

Study on soaps made from Non Edible Oil such as Jatropha Oil revealed that these surfactants have bactericidal effects. In present research different soap samples (solid as well as liquid) were prepared by mixing lye solution with blend of Non Edible Jatropha oil with Castor oil and Coconut Oil. Essential oils like Tea tree Oil, Thyme oil, Peppermint and D - limonene were included in these soaps to improve their quality and impart pleasant fragrance. pH of final product was tested with the help of Universal indicator and pH meter and it was in the range of 7-9 which is under prescribed limit of BIS. Antimicrobial activities of all the soaps were determined quantitatively at concentration range of 50 ppm to 200 ppm by using Cup Borer method in nutrient agar medium. Test organisms selected were Bacillius cereus, B. megaterium, Staphylococcus aureus, Eschericia coli, Pseudomonas aeruginosa, Aspergillus niger and Candida albicans. Liquid Surfactants made by combining Jatropha oil and Essential oils have remarkable antibacterial activity on Pseudomonas and it could be developed as disinfectant to sterilize catheters and surgical equipments to control nosocomial infections in Hospitals. Study on Aspergillus confirms fungicidal activity of these surfactants. As these surfactants are biodegradable in nature they could be considered as a better eco friendly (green) alternative to harmful chemical fungicides which are used in agricultural fields and have several adverse effects on ecosystem. Solid as well as liquid surfactants from Jatropha oil have a potential to become significant product in Cosmetic, Pharmaceutical and Agrochemical sector.
