11.2 Additional Information
RTECS: MJ9700000
To the best of our knowledge, the chemical, physical, and toxicological properties have not been thoroughly investigated.
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 information
Further data:
Handle in accordance with good industrial hygiene and safety practice.
