Blown Castor Oil – Brown or oxidized castor oil is prepared by blowing air or oxygen into it at temperatures of 80o C to 130o C, with or without catalyst to obtain oils of varying viscosity. The process is called oxidative polymerization. This increases the viscosity and specific gravity of the oil.

Blown Castor Oil is a Castor Oil derivative that has a higher viscosity and specific gravity than natural Castor Oil. These properties are induced by bubbling air through it at elevated temperatures.
