Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information

EC50 0.1-1 mg/L algae spp. (r-a)

Key value for chemical safety assessment

Additional information

An EC50 value in the range 0.1-1 mg/L has been estimated for the effects of the undecanol, linear and branched on algal growth. The estimate is based on expert judgement, which takes into consideration measured and predicted ecotoxicity values for other trophic levels and the relative susceptibility of algae compared to such trophic levels, in the same substance category. The estimation has been determined as a range due to the uncertainty associated with this kind of prediction.
