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.
