Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

There are data on acute toxicty to daphnia for three representatives of the Guerbet alcohol category.

The C12 Guerbet alcohol 2-butyloctan-1-ol show acute toxicity to daphnia in contrast to the higher alcohols 2-hexyldecan-1-ol (C16) and mixture of 2 -octyldodecan-1-ol and 2 -hexyl-1-tetradecanol (C20) which show no acute toxicity to daphnia up to the limit of water solubility. These effects can be a consequence of decreasing water solubility with increasing chain length. Thus no aquatic toxicity is considered for the Guerbet alcohols with chain lengths >= C16 with an extremely low water solubility.
