CHEMICAL AND PHYSICAL PROPERTIES
| Physical Description | Chloroacetic acid, solid is a colorless to light-brown crystalline material. It is soluble in water and sinks in water. Combustible. It is transported as a molten liquid and therefore can cause thermal burns. It is toxic by ingestion, skin absorption and inhalation of dust. It is corrosive to metals and tissue. |
