Repeated dose toxicity - Rat - male and female - Oral - 3 Months - NOAEL (No observed adverse effect level) - 143 mg/kg
Remarks: The value is given in analogy to the following substances: Cyclohexanone
Prolonged or repeated exposure to skin causes defatting and dermatitis., burning sensation, Cough, wheezing, laryngitis, Shortness of breath, Headache, Nausea, Vomiting,
Central nervous system depression, Incoordination., To the best of our knowledge, the chemical, physical, and toxicological properties have not been thoroughly investigated.
Systemic effects:
After absorption of large quantities:
Headache
Salivation
Nausea
Vomiting
Dizziness narcosis
Coma
The following applies to ketones in general: when vapours/aerosols occur, mucosal irritations, coughing, and dyspnoea after inhalation. The absorption of large quantities leads to: CNS depression (narcosis). Repeated skin contact leads to a degreasing effect, with secondary inflammation possible. Toxic effects on the liver and kidneys cannot be excluded after high doses. The inhalation of droplets may result in the formation of oedemas in the respiratory tract.
Other dangerous properties can not be excluded.
Handle in accordance with good industrial hygiene and safety practice.
