CHEMICAL AND PHYSICAL PROPERTIES
| Physical Description | It is a solid when pure, however, it is often formulated as a solution in organic solvents which may be flammable. Generally denser than water and insoluble in water. Vapors heavier than air. Toxic by inhalation, ingestion, or skin absorption. Formerly used as a pesticide but it has been banned in the US since 1988. |

PRODUCT INTRODUCTION
description
Chlordane is a manufactured chemical that was used as a pesticide in the United States from 1948 to 1988. Technical chlordane is not a single chemical, but is actually a mixture of pure chlordane mixed with many related chemicals. It doesn't occur naturally in the environment. It is a thick liquid whose color ranges from colorless to amber. Chlordane has a mild, irritating smell. Some of its trade names are Octachlor and Velsicol 1068. Until 1983, chlordane was used as a pesticide on crops like corn and citrus and on home lawns and gardens. Because of concern about damage to the environment and harm to human health, the Environmental Protection Agency (EPA) banned all uses of chlordane in 1983 except to control termites. In 1988, EPA banned all uses.
