Description of key information

With high probability acutely not harmful to algae.

Key value for chemical safety assessment

EC50 for freshwater algae:
5 940 mg/L
EC10 or NOEC for freshwater algae:
1 180 mg/L

Additional information

In a non-GLP, 72-hour static test with the green alga Scenedesmus subspicatus (new name: Desmodesmus subspicatus) according to German Industrial Standard DIN 38412 part 9, the algae toxicity of Hexane-1,6 -diol was investigated (BASF 1989). Statistical evaluation of the endpoint growth rate revealed an EC50 (72h) of 5940 mg/L, the EC10 (72h) was calculated to be 1180 mg/L, both related to the nominal concentration.
