Urethane-Grade Castor Oil & Castor Polyols

Castor oil is natural oil obtained from the seed of the castor plant, produced primarily in India, China, and Brazil. Scientific and historical records reveal that regardless of the oil’s origin, its chemical nature and composition are remarkably uniform. Campbell & Co. provides only the best quality urethane-grade castor oil and castor polyols.


Castor oil low-moisture (COLM) made from Castor Oil #1 and castor oil low-moisture pale-pressed (COLMPP) made from Pale-Pressed Castor Oil are refined, urethane-grade castor oils used in specific applications that require minimum moisture. Typical applications include urethane coatings, adhesives, and inks, but can also be used in urethane blowing and urethane molding. This product may be made with a lighter color and lower acid values upon request.

Castor naturally has extremely low moisture content at .25%. Urethane-grade castor oil is brought down to a moisture content of .025%. This reduces the amount of urethane that is polymerized by moisture during formulation.

Our urethane grade castor oil reacts with urethane-based adhesives and coatings as a curing catalyst. The low moisture content assures stronger structural integrity.

Castor Polyols

Castor Polyols are engineered to provide varying hydroxyl groups to meet the needs of your specific application. Traditionally, chemists would use petroleum-based polyols for curing; however, a more environmentally friendly option now exists. Campol Lubricants offers a product with little or no petroleum additives. This is the most environmentally safe option for formulating.
