Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 study was performed according to OECD Guideline 301-B/EU method C4-C and GLP guidelines.

Key value for chemical safety assessment

Biodegradation in water:
readily biodegradable

Additional information

Under the conditions of the modified Sturm test presently performed, at least a part of the components of the mixture Radia 7838 were biodegradable. Based on the 28-day degradation curves, complete degradation can be estimated to be reached after 150 to 170 days. As a principle, this type of screening study is intended for pure chemicals as it does not include identification of those components in a mixture, which are degradable or non-degradable.
