WHITENING AND COLOR IMPROVING IN TOILET SOAP MANUFACTURE WITH THE STUDY OF SOME PHYSICOCHEMICAL PROPERTIES

Soap is one of the most effectual cleaning agents in water. Soaps are prepared by the process of saponification reaction. Sodium and potassium salts soap is used for both laundry and antiseptic purposes. Toilet soap is the perfumery and cosmetic product and serves for personal hygiene, so it should have the broadest possible range of specific characteristics. This study was undertaking to address the raw material in soap and method of saponification and manufacturing usage. The study was also conducted some of the physical and chemical properties such as: (pH, Total dissolve solids (TDS), free alkali, saponification valueof toilet soaps). The study revealed that soapbleaching is usually done to improve color, remove impurities and improve taste. Sodium chloride and sodium silicate were used as bleaching chemicals as well as improving the color the toilet soapmanufacture.
