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.

Description of key information

In accordance with column 2 of REACH Annex X the study on “Long-term toxicity to sediment organisms” (required in section 9.5.1) shall only be proposed if the chemical safety assessment indicates the need to investigate further. Conclusive experimental results are available for fish, invertebrates (daphnia), algae and microorganism. The lowest effect level was the NOEC of 2.9 mg/L from a chronic study in daphnia. Guanidine nitrate is inherently biodegradable and has a low potential for bioaccumulation. In conclusion no classification according to GHS Regulation EC No 1272/2008 for acute or chronic aquatic toxicity is required.   Taken together for environmental hazard assessment and PNEC derivation, it is appropriate to conclude “No hazard identified”. Thus no further testing is required.
