CHEMICAL AND PHYSICAL PROPERTIES
| Physical Description | Chlorfenvinfos is an amber-colored liquid with a mild chemical odor. Used for control of ticks, flies, lice, and mites on cattle and for blowfly, lice, ked, and itchmite on sheep. Controls fleas and mites on dogs; not used on cats. Applied on organic wastes and breeding places of fly larvae. Also used as a foliage insecticide for potatoes, rice, maize, and sugar cane. Used to control soil insects. (EPA, 1998) |

PRODUCT INTRODUCTION
description
Chlorfenvinphos is an insecticide that is a colorless liquid with a mild odor. It was commonly used until 1991 when all products containing chlorfenvinphos as an active ingredient were canceled in the United States. Commercial preparations commonly sold in stores were usually 90% chlorfenvinphos. Most of the chlorfenvinphos used was in liquid form. Chlorfenvinphos was widely used to control household pests such as flies, fleas, and mice. The chemical is manufactured and does not occur naturally in the environment. It was sold under common trade names including Birlane®, Dermaton®, Sapercon®, Steladone®, and Supona®. Use of trade names is for identification only and does not imply endorsement by the Agency for Toxic Substances and Disease Registry, the Public Health Service, or the U.S. Department of Health and Human Services.
