Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Additional information - workers

As an acute toxicity hazard leading to Classification and Labelling of the substance has not been identified, the long-term DNEL is considered sufficient to ensure that effects from acute exposure to the substance do not occur (in accordance with ECHA Guidance on information requirements and chemical safety assessment: Chapter R.8: Characterisation of dose [concentration]-response for human health, May 2008 and Part B: Hazard Assessment, Draft new chapter B.8 Scope of Exposure Assessment, March 2010).

Route-to-route extrapolation has been performed. In absence of relevant data, only differences between the different routes as determined by the assumed percentages of absorption into the systemic circulation could be accounted for (see toxicokinetic assessment).

Absorption oral (rat) = Absorption oral (human) = 100%

Absorption dermal (human) = 10%

Absorption inhalation (human) = 100%
