Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

In accordance with column 2 of REACH Annex IX, further degradation testing does not need to be conducted as the chemical safety assessment does not indicate a need for further investigation and process measures should ensure that there would be little or no exposure to sediment. Some degradation date is available for cresols which show  full degradation in up to 4 weeks.

Key value for chemical safety assessment

Additional information

Some data for cresols are available and show that o-cresol is 90% degraded in 24 hours (Manunaga, 1983), p-cresol is completely degraded in 4 weeks in freshwater sediment (Haeggblom, 1992). o-cresol is not degraded in anaerobic conditions (Horowitz, 1982).
