First Special Grade
Castor Oil FSG is produced by refining commercial grade castor oil through bleaching and filtering. It is a pale yellow, viscous, non-drying oil. It is unique among vegetable oils due to its high content of Ricinoleic Acid (~87%), which gives it unusual chemical properties like alcohol solubility and high viscosity.
FSG Castor Oil is the standard grade for industrial applications. It retains its viscosity at high temperatures and does not freeze easily at low temperatures. It serves as the primary raw material for manufacturing Hydrogenated Castor Oil (HCO), 12-Hydroxy Stearic Acid (12-HSA), and various Sebacic Acid derivatives.
Meets B.S.S. 650:1967 Standards.

Normal vegetable oils (like Soy or Palm) are non-polar. Castor Oil is different because of one specific feature: the Hydroxyl Group (-OH) on the 12th carbon of Ricinoleic Acid.
Castor Oil is extremely viscous (approx 700-900 cPs at 25°C). In winter, pumping it from ISO tanks or Flexibags can be very slow.
Recommendation: Ensure your storage tanks have heating coils or use pump tracing to maintain a temperature of 30°C-40°C for efficient flow.
Used as a Bio-Polyol in the production of PU foams, casting resins, and adhesives.
Base for high-temperature greases and racing engine oils due to its thermal stability.
Dehydrated Castor Oil (DCO) is used in alkyd resins to provide flexibility and water resistance.
Sulfated Castor Oil (Turkey Red Oil) is used as a wetting agent and dye dispersant.
Precursor for Sebacic Acid, Undecylenic Acid (antifungal), and Nylon 11.
Used in lipsticks (for shine) and creams. (Note: Use BP/USP grade for direct pharma use).
Standard export packing. Epoxy coated drums available.
Most economical for bulk export (21-22 MT per container).
Direct from Origin. Best Industrial Grade Prices.
