Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Local effects

Hazard assessment conclusion:
no hazard identified

Additional information - workers

The substance doesn't react easely with other substances , environment and human body. An acute exposure via all three route (oral, dermal, inhalation) don't represent an hazard for standard value. And also for long term exposure , all DNEL value are very high for all route of exposure.

Additional information - General Population

The substance doesn't react easely with other substances , environment and human body. An acute exposure via all three route (oral, dermal, inhalation) don't represent an hazard for standard value. And also for long term exposure , all DNEL value are very high for all route of exposure and also for all population category.
