THE STORY OF CASTOR OIL
Castor Oil: The Rich, Gloss-Enhancing Oil for Skin, Hair & Lip Care
Castor Oil is a highly stable, thick vegetable oil pressed from Ricinus communis seeds. Naturally rich in ricinoleic acid, it offers strong film-forming, moisturizing, and gloss-boosting effects — widely used in lip care, hair oils, body butters, ointments, and conditioning emulsions. Known for both cosmetic and medicinal heritage.
Cold-Pressed from Castor Seeds, Refined for Cosmetic Purity
Castor seeds are cleaned, cold-pressed, and filtered to remove proteins and impurities. The resulting oil may be refined, bleached, deodorized (RBD) or supplied as virgin cold-pressed grade. TRCkem offers pharma, cosmetic, and hydrogenated grades depending on viscosity and clarity required in formulation.
