SYNTHESIS OF SOAP FROM EDIBLE OILS USING A BIO-BASED CATALYST DERIVED FROM MUSA BALBISISANA COLLA AND A COMPARATIVE STUDY OF QUALITY PARAMETERS

Soaps were synthesized by mixing various edible oils such as coconut oil, mustard oil, vegetable oils, olive oil, and soybean oil using banana ash of banana (Musa balbisiana Colla.) peel (BPA) as a bio-based catalyst. To improve color, odor, and other qualities controlled quantities of fillers, permissible natural colors, and fragrances were added. Soaps prepared from edible oils were compared with popular soaps in terms of several parameters such as % yield, TFM (total fatty acid matter) value, total alkali content, free caustic alkali content, pH, and acid value. It was found that the TFM value of edible oil soap is more than 65% for maximum cases two of them, which have been prepared using coconut oil and olive oil, have TFM value of more than 75%. According to BIS norms, these two types of soap can be categorized as Grade I soap, and the rest are Grade II soaps and it can be used for general bathing purposes. Also, total alkali content, free caustic alkali content, pH value, etc. were found within the prescribed value of BIS.
