Description of key information

During three hour OECD 209 test with branched triamine C16-18 both the EC50 and EC10 were determined.

Key value for chemical safety assessment

EC50 for microorganisms:
86 mg/L
EC10 or NOEC for microorganisms:
17 mg/L

Additional information

The EC10 should be used for the derivation of the PNEC micro-organisms as this value will have the highest predictive power.
