Analysis and Identification of two Soaps by Infrared Absorption Spectra and Reflectance Graphs
Two soap bars one green and another white green were analyzed, and their total fatty matter content, unsaponifiable, un-saponified and un-saponified saponifiable matter content, ethanol-insoluble matter, and free caustic alkali content were determined. The infrared spectra of total lipids, unsaponifiable fats, and insoluble matter in ethanol, were recorded for the two soaps. The Kubelka-Munk K/S values were calculated using the expression depended on reflectivity R͚ of the observed soap’s surface, as well as the CIE L*a*b* values for both soaps.
