Zopiclone
Zopiclone was developed and first introduced in 1986 by Rhône-Poulenc S.A., now part of Sanofi-Aventis, the main worldwide manufacturer. Initially, it was promoted as an improvement on benzodiazepines, but a recent meta-analysis found it was no better than benzodiazepines in any of the aspects assessed. On April 4, 2005, the U.S. Drug Enforcement Administration listed zopiclone under schedule IV, due to evidence that the drug has addictive properties similar to benzodiazepines.
Cosmoline
Cosmoline was developed by Houghton International in the late 1800's as a pharmaceutical product. The original Cosmoline was an ointment and was used for many different cosmetic and medical purposes. It was kept in homes to disinfect wounds and was used by veterinarians to treat cuts, abrasions, bruises and sprains. Cosmoline could even be found on the farms where it was used to relieve swelling in cow's udders. Cosmoline became an everyday name when it received a government specification as a rust preventive and began being used by the military to protect its equipment from rust and corrosion. Cosmoline could be found on military equipment in the Spanish-American War, World War I, World War II, the Korean and Vietnam Wars. Cosmoline conforms to MIL-SPEC (MIL-C-11796C, Class 3) for Preservative and Sealing Compounds.
