Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Toxicity to microorganisms: not toxic to microorganisms: inhibition of respiration rates <15% (OECD 209, activated sludge respiration inhibition test)

Key value for chemical safety assessment

EC10 or NOEC for microorganisms:
1 000 mg/L

Additional information

Respiration rates were decreased by, at most, 8% at a test substance concentration of 10 mg/L and 5% in one mixture at 1000 mg/L. Since the permitted maximum difference for specific respiration rates in control beakers established at the beginning and end of the test period was 15%, this value is taken as the criteria for biologically significant levels of inhibition in mixtures containing the test substance.
