Study of the physical and chemical properties of various types of solid soaps traded in the Libyan market

Abstract:This study included the study of some physical and chemical properties of some samples of the solid soaps circulating in the Libyan market. These characteristics were as following :   the  percentage of moisture, the percentage of fatty matter, the percentage of total fatty matter, the percentage free  caustic  alkali, the percentage of total  alkali  ,  the percentage  of chloride, the acidic function pH, the refractive index R.I,  and the electrical conductivity EC. Values  of the moisture  content   was ranged   from 3.6% to 7.8%,  the total fatty matter rounded in range 61.1% to 88%, the free  caustic  alkali was  presented in region of 0.01% to 0.15%, total  alkali  ranged  between  0.039% and 0.058%, the percentage  of chloride ranged between 0.67%  and  1.4%  and pH  was  recorded between 6.29 to10.16. Finally, the values of refractive index was 1.29 as the lowest value and 2.5 as the highest value, and the electrical conductivity recorded between 324µs to 756µs.
