Procedure

317.5 Kg of calcium hydroxide was charged to a Littleford mixer, followed by addition of 11.3 Kg of water. 606.9 Kg of melted stearic acid was then added with high intensity mixing. Total batch time was 30 minutes with reaction time of approximately 15 to 20 minutes. The analysis of the product showed an ash content of 26.95 percent.
