Ricinoleic Acid (Food Grade and Technical Grade)

Ricinoleic Acid (Food Grade and Technical Grade)


Ricinoleic acid is a a pale yellow to light red colored Fatty Acid formally called 12-hydroxy-9-cis-octadecenoic acid is a fatty acid that naturally occurs in mature Castor Plant. Ricinoleic Acid is derived from fractional distillation or saponification of Castor Oil. Ricinoleic Acid is generally used in liquid form. It is an unsaturated omega-9 fatty acid and a hydroxy acid. A liquid, hydroxy fatty acid with a double bond in the 9-10 position and a hydroxyl on the 12th Carbon, it imparts lubricity and rust-proofing Qualities to Soluble Cutting Oils. Ricinoleic Acid (12-hydroxy-9-octadecenoic acid) is obtained by the hydrolysis of Castor Oil. It is a light colored liquid with a ricinoleic content of approximately 87%. Ricinoleic acid is the active component of castor oil. The Ricinoleic Acid has three functional groups in its molecule. The carboxyl terminal, the unsaturated bond on carbon 9 and the hydroxyl on carbon 12. Resulting in specific chemical characteristics that can be exploited in various production processes such as: for colour enhancer, additives for cutting oils, to increase lubricity and reduce rust, in germicidal soaps, as an emulsifier and softener, production of pharmaceuticals, foam stabilizers, among other applications including chemical synthesis.

Ricinoleic Acid possesses remarkable analgesic and anti-inflammatory properties. It is an effective topical treatment material for ringworm, keratoses, skin inflammation, abrasions, fungus-infected fingers and toenails, acne and chronic pruritus (itching). It can also be used for treating leather, rendering good wetting, flexibility and softening properties to it.

Ricinoleic acid is effective in preventing the growth of numerous species of viruses, bacteria, yeasts, and molds. It's successful as a topical treatment for ringworm, keratoses, skin inflammation, abrasions, fungal-infected finger- and toenails, acne, and chronic pruritus (itching).
