Description of key information

No studies assessing chronic effects on invertebrate are available.

Key value for chemical safety assessment

Additional information

 Acute toxicity studies for the three representative trophic levels report LC50/EC50 values >300 mg/L, thus the substance is not considered hazardous to aquatic species. Acute toxicity studies for the three representative trophic levels report LC50/EC50 values >100 mg/L, thus the substance is not considered hazardous to the environment. Tris-amino met the criteria of readily biodegradable within the 10 day window and has with a low potential for bioaccumulation (log Kow=-2.31). According to REACH Annex IX requirements, long-term toxicity testing shall only be considered when the chemical safety assessment indicates the need for further investigations. Hence, long-term testing in invertebrates can be waived.
