It can serve as a biomarker of ricin poisoning. [3] [4] It was first isolated from the castor seeds by Tuson in 1864. [5] [6] Ricinine has insecticidal effects. [7] It sublimes between 170 and 180 °C at 20 mmHg. It does not form salts, and is precipitated in iodine or mercuric chloride solutions, but not in Mayer's reagent. [5]
Ricin (/ ˈ r aɪ s ɪ n / RY-sin) is a lectin (a carbohydrate-binding protein) and a highly potent toxin produced in the seeds of the castor oil plant, Ricinus communis.The median lethal dose (LD 50) of ricin for mice is around 22 micrograms per kilogram of body weight via intraperitoneal injection.
Some 270,000–360,000 tonnes (600–800 million pounds) of castor oil are produced annually for a variety of uses. [4] Castor oil and its derivatives are used in the manufacturing of soaps, lubricants, hydraulic and brake fluids, paints, dyes, coatings, inks, cold-resistant plastics, waxes and polishes, nylon, and perfumes.

Canola oil is not castor oil, and the linked page makes no mention of castor oil, castor beans, or ricin. I removed the external link due to being a complete non sequitur. Now, if anyone has a good link for the toxicity (or lack thereof) of castor oil, that would be useful. 152.17.148.93 ( talk ) 16:43, 18 April 2013 (UTC) [ reply ]
Zinc ricinoleate is the zinc salt of ricinoleic acid, a major fatty acid found in castor oil.It is used in many deodorants as an odor-adsorbing agent. The mechanism of this activity is unclear.
