Chloramine B

== Description ==
White powder with a faint chlorine odor. Chloramine B was first introduced as a bleach for paper in 1937, however it is no longer in use. Chloramine B in weak solutions (2%) initially appeared to be a satisfactory easily controllable bleach. However, it reacts with aluminum and other metals to form insoluble precipitates that are difficult to remove. Residual chloramine B may continue to bleach for many months. It has also been used as an antiseptic.

Chlordane

== Description ==
A pale yellow, oily liquid used as an insecticide. Chlordane was introduced in 1945 for the control of cockroaches. Within ten years, it was the most widely used insecticide in the United States.

Chlorine

== Description ==
A nonmetallic halogen element. Chlorine has an abundance of 0.031% in the earth's crust (halite, sylvite, carnallite) and 1.9% in seawater (chloride salts).

Chlorofluorocarbon

== Description ==
Any of various halocarbon compounds containing carbon, hydrogen, chlorine, and fluorine. The first chlorofluorocarbon (CFC), named Freon®, was developed in 1928. Since CFC's were chemically inert, non-irritating and nonflammable, they were chosen to replace [[ammonia (anhydrous)|ammonia] and sulfur dioxide as refrigerants. Other applications soon followed, such as aerosol propellants, fire extinguishers and blowing agents for foams. By the 1970s, it was determined that CFC's decompose in the stratosphere releasing atomic chlorine that reacts with ozone. This depletion of the ozone layer led to the phased prohibition of CFC's in 1979. Examples of CFC's are Freon, Halon, Frigen, Arcton, trichlorofluoromethane, and dichlorodifluoromethane.
Chlorofluorocarbon is on the ILFI Red list of building materials.
== Synonyms and Related Terms ==
CFC; FCC; Freon®; Frigen; Halon; Arcton; trichlorofluoromethane; dichlorodifluoromethane
