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

Ready biodegradation screening test:

EU Method C.4 -E (equivalent to OECD 301 D), test substance concentration 0.8 mg/L, ThOD 2.77 mg/mg TS/L: 83% biodegradation in 28 days; readily biodegradable (Currenta, 2010)

Inherent biodegradation screening test:

equivalent to OECD Guideline 302B, initial concentration 200 mg/L COD: 94.6% DOC removal in 5 days; inherently biodegradable (Pitter, 1976)

No further simulation tests are considered necessary, since thymol is readily biodegradable.
