Comments

TSCA Definition 2008: A mixture of crude oil distillates with boiling points of 60 deg C to 110 deg C; [ChemIDplus] Petroleum distillates, e.g., VM & P naphtha and kerosene, can cause anesthesia, slowing of reflexes and dermatitis. They may contain n-hexane with the potential to cause peripheral neuropathy. [LaDou, p. 543] Aliphatic and aromatic hydrocarbons cause trivial hepatic injury in animal experiments. [Haddad, 226t] Petroleum ether is in the list of "Some volatile substances which may be abused by inhalation" published on the web site of the U.N. International Drug Control Programme, indicating its potential to cause narcosis in workers. [Reference #1]
