Description of key information

Acutely harmful to aquatic algae and cyanobacteria.

Key value for chemical safety assessment

EC50 for freshwater algae:
48.6 mg/L
EC10 or NOEC for freshwater algae:
28.1 mg/L

Additional information

In a non-GLP, 96-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 2,6-dimethylcyclohexylamine was investigated. Statistical re-evaluation of the endpoint growth rate revealed an EC50 (72h) of 48.6 mg/L, the EC10 (72h) was estimated to be 28.1 mg/L, both related to nominal test concentrations.

In conclusion, the substance is acutely harmful to aquatic algae and cyanobacteria.
