Chili Pepper and Oleoresin Capsicum

Chili peppers (Capsicums) are different in taste, appearance, aroma, pungency, color, origin, growing process, DNA structure and toxicity levels. Capsicum consists of 38% pericarp, 2% inner sheath, 56% seeds, and 4% stalks. The property that separates the Capsicum family from other plant groups and the quintessence of the chili pepper is an alkaloid called Capsaicin (kap-sa-i-sin), an unusually powerful and pungent crystalline substance found in no other plant.

Tear Gas Dibenzoxazepine

Chemical weaponry was first used in the United States in the Civil War at the siege of Charleston. Wood was saturated with sulphur and burned under the parapets around the city hoping that favorable winds would propel huge clouds of choking smoke to drive out the defenders. French law enforcement is reputed to have been the first police organization to have used a chemical lachrymator (tear-producing) in a hand-thrown device.

Tear Gas Orthochlorobenzylidenemalononitrile

Agent CS (Orthochlorobenzylidenemalononitrile) was first prepared in 1928 by two American chemists, Ben Corson and Roger Stoughton. (The CS initials were taken from the first letters of the names of the discoverers). However, it remained until 1956 for the British CBW laboratory at Porton Down, the Chemical Defense Experimental Establishment, to develop CS as a riot control agent.

Tear Gas Chloroacetophenone

Early records reveal that German scientists discovered CN (Chloroacetophenone) about 1870. This is a chemical compound that was first prepared for use in 1877 but was not subsequently used to any great extent. The French were the first to use it successfully in the late 1920s to break up civil disorders in their colonies. It was then adopted practically all over the world for use by law enforcement agencies around 1930.

Tear Gas Diphenylaminochlorarsine

Agent DM (Diphenylaminochlorarsine) was developed by the American chemist Roger Adams of the US Chemical Warfare Division during World War I as an improvement on diphenylchlorarsine, the latter having been introduced by the Germans in 1913. DM is commonly called adamsite or vomiting Gas. It contains about 27 per cent arsenic. On re-crystallization from benzene-glacial acetic acid, DM is a yellow solid with essentially no odor.
