Toxic substances list: dichloromethane
Dichloromethane (also known as methylene chloride, or DCM) is a colourless, volatile organic liquid that does not occur naturally. It is soluble in most organic solvents and has a high evaporation rate. These properties make dichloromethane a versatile substance, and it is used in a wide variety of applications including as a solvent in paint and furniture stripping products, a blowing agent in foam production, as a component in aerosol products, and in other industrial process applications.
