Acetonitrile formulations for nail polish remover, despite its toxicity. At least two cases have been reported of accidental poisoning of young children by acetonitrile-based nail polish remover, one of which was fatal. Acetone and ethyl acetate are often preferred as safer for domestic use, and acetonitrile has been banned in cosmetic products in the European Economic Area since March 2000. In common with other nitriles, acetonitrile can be metabolised in microsomes, especially in the liver, to produce hydrogen cyanide, as was first shown by Pozzani "et al." in 1959. The first step in this pathway is the oxidation of acetonitrile to
Choline chloride it accelerates growth. It forms a deep eutectic solvent with urea, ethylene glycol, glycerol, and many other compounds. It is also used as a clay control additive in fluids used for hydraulic fracturing. Other commercial choline salts are choline hydroxide and choline bitartrate. In foodstuffs the compound is often present as phosphatidylcholine. Choline chloride Choline chloride is an organic compound with the formula (CH3)3NCH2CH2OH]Cl. It is bifunctional, containing both quaternary ammonium salt and an alcohol. The cation is choline, which occurs naturally. It is a white, water soluble salt used mainly in animal feed. In the laboratory, choline can be
