Description of key information

Key value for chemical safety assessment

EC50 for freshwater algae:
28.3 µg/L
EC10 or NOEC for freshwater algae:
9.77 µg/L

Additional information

Based on the definitive test results, it can be concluded that 2-Propanol, 1,1'-[[3-[(3-aminopropyl)amino]propyl]imino]bis-, N-tallow alkyl derivatives are very toxic to algae with an ErC50 of 28.3 µg/L and a NOEC of 9.77 µg/L (nominal). Due to analytical method limitations one can expect that the toxicity threshold is even lower. The study was carried out in according with OECD Guideline 201.
