Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
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
The effect of P5117 on the respiration rate of activated sludge was assessed by the methods detailed in EC Directive 87/302, 'Biodegradation - Activated Sludge Respiration Inhibition test' and OECD Test Guideline 209, 'Activated Sludge, Respiration Inhibition test'. Two tests were conducted: a preliminary screen, at nominal concentrations of 1, 10 and 100 mg/l and a final limit test at 100 mg/l. P5117 had no inhibitory effect on the respiration rate of activated sludge at any of the concentrations employed in the test. The EC20, EC50 and EC80 of the test material could not therefore be calculated but these must be greater than 100 mg/l, the highest tested level.
Key value for chemical safety assessment
- EC50 for microorganisms:
- 100 mg/L
- EC10 or NOEC for microorganisms:
- 100 mg/L
