Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

A study according to OECD Guideline 301F is available. The results of the study indicate that the substance cannot be characterized as 'readily biodegradable'.

Key value for chemical safety assessment

Biodegradation in water:
under test conditions no biodegradation observed

Additional information

Based on the CO2 analysis results from this study, the test substance cannot be characterized as ‘readily biodegradable’ according to the OECD 301B guideline (since it did not reach 60% or greater CO2 evolution within a 10-day window of exceeding 10% biodegradation).  The rapid degradation of the reference substance confirmed the presence of an acceptable microbial community and confirmed system integrity. However, the test concentrations used were above the separately determined water solubility limit of 0.22 mg/L.
