PHYSICO-CHEMICAL ANALYSIS OF SOAP PRODUCTION FROM NEEM SEEDS OIL
Abstract
Soap is sodium or potassium salt of fatty acid produced by saponification reaction using sodium
or potassium hydroxide. It is used for cleaning, bathing, and washing. Soaps were produced from
neem seed oil and sheabutter oil using the cold process method with slight modification. The
physicochemical properties (acid value, saponification value, peroxide value, iodine value and
moisture content) of the oil were determined and it showed that the values are within the
standard specifications. The quality of the soaps were also assessed by determining the
physicochemical properties such as; pH test, solubility test, foamability test cleaning properties,
washing properties and moisture content. All the results obtained showed that the soaps
analyzed are good soaps safe for the skin.
