Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Testing for long term toxicity to fish is not considered necessary because:

  • The needs associated with a sound understanding of long-term aquatic toxicity to fish are adequately met by the available data on constituents. For the purpose of risk assessment aquatic PNECs have been derived from the available data with each separate constituent.


  • A recent long-term toxicity test has been carried out with the structurally analogous substance decan-1-ol. There was intensive method development to attempt to overcome very significant biodegradation losses of substance in the test system. Whilst testing is not technically impossible, it requires very significant efforts which are disproportionate to the need for data.
