Description of key information

One toxicity test with algae has been performed. The 72 h ErC10  is 188 µg/L and the 72 h ErC50 = 507 µg/L based on the test substance (92.3% diamine and 7.7% primary alkyl amine). The effects are expressed as nominal values because the tests were performed with river water as they are intended to be used in an evaluation of the environmental risks based on the Bulk approach.

Key value for chemical safety assessment

EC50 for freshwater algae:
507 µg/L
EC10 or NOEC for freshwater algae:
188 µg/L
