CHEMICAL AND PHYSICAL PROPERTIES
| Physical Description | Captan is a white solid dissolved in a liquid carrier. It is a water emulsifiable liquid. It can cause illness by inhalation, skin absorption and/or ingestion. The primary hazard of this material is that it poses a threat to the environment. In case of release immediate steps should be taken to limit its spread to the environment. Since it is a liquid it can easily penetrate the soil to contaminate groundwater. It is used as a fungicide. |
