Castor oil has infinite possibilities.

“Castor oil” is light yellow viscous non-drying oil obtained from the seeds of Ricinus Communis and has unique physical properties which cannot be found in the other various vegetable oils.
Its characteristics are “high viscosity (flexibility), high hydroxyl value, solubility in alcohols and slightly solubility in petroleum-based solvent”.
In addition, we will be able to contribute to developments of environmentally friendly products that are useful in reduction of CO2 emission and effectively use of environmental resources.
