dc.description.abstractIndirect leaching was used to extract castor oil from the castor beans. A hydraulic brake fluid was formulated by mixing the castor oil, solvents and other additives at various proportions using unifactor design approach. Both the castor oil and brake fluid was analysed to determine their physiochemical properties. Results show that the castor oil has high viscosities of 29.29Cst and 19.54Cst at 40oC and 100 oC , respectively, specific gravity of 0.927 at 30oC/30oC, acid and saponification values of 3.5 and 186.0 respectively. On the other hand, the best fitted formulation (Castor oil, solvent and additives) of hydraulic brake fluid has reduced viscosities of 19.54Cst and 2.33 Cst at 40°C and 100°C respectively. The flash and boiling points were found to be 124.25 and 220.05 respectively.
