Stability and reactivity
STABILITY: Product stable up to 140°C
CONDITIONS TO AVOID: None known
MATERIALS TO AVOID: Certain strong oxidizing agents such as Sodium Hypochlorite and Hydrogen Peroxide
HAZARDOUS DECOMP PRODUCTS: Nitorgen oxides are formed when denatonium benzoate decomposes on heating or when involved in fire
Oral LD50 (Female Rat) 584 mg/kg
Oral LD50 (Male Rat) 640 mg/kg
Oral LD50 (Rat) >2000 mg/kg
INHALATION: Only one known case of toxic effect in man from denatonium benzoate causing asthmatic persons who are allergic to Lignocaine or some similar anesthetics may also react to denatonium benzoate and should therefore avoid contact with the material.
INGESTION: Bitterest substance know to man. No information on adverse effects.
SKIN: Low skin sensitivity potential and therefore may be mildly irritating to skin.
EYES: No information available
Denatonium does not bio-accumulate
