Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

No data on the biodegradation in simulation tests are available for the members of the stilbene fluorescent whitening agents category.

Key value for chemical safety assessment

Additional information

No data on the biodegradation in soil are available for the stilbene fluorescent whitening agents category. However, further biotic degradation testing shall be proposed if the chemical safety assessment according to Annex I indicates the need to investigate further degradation of the substance and its degradation products. The test substances in the stilbene fluorescent whitening agents category were found to be non-biodegradable in studies concerning ready and inherent biodegradability as well as BOD5.

It is assumed that the test substances in the stilbene fluorescent whitening agents family are not biodegradable in simulation tests either. Therefore, simulation studies soil are not provided.
