Cadmium stearate Consensus Reports
EPA Extremely Hazardous Substances List. Cadmium and its compounds are on the Community Right-To-Know List. Reported in EPA TSCA Inventory.
Cadmium stearate Safety Profile
Confirmed human carcinogen. Poison by inhalation. Moderately toxic by ingestion. Human systemic effects by inhalation: hallucinations or distorted perceptions; nausea or vomiting, other gastrointestinal effects; weight loss or decreased weight gain; cardiac effects. When heated to decomposition it emits toxic fumes of Cd. See also CADMIUM COMPOUNDS.
Risk Statements 20/21/22-50/53
R20/21/22:Harmful by inhalation, in contact with skin and if swallowed.
R50/53:Very toxic to aquatic organisms, may cause long-term adverse effects in the aquatic environment.
Safety Statements 45-53
S45:In case of accident or if you feel unwell, seek medical advice immediately (show the label whenever possible.)
S53:Avoid exposure - obtain special instructions before use.
