Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Additional information
Ethylbenzene is a volatile substance which is difficult to test for biodegradation in the experimental systems. The estimated QSARs data on environmental degradation of ethylbenzene are summarized in table below. Overall, the QSAR estimated data suggest that this substance will degrade fast in the environment.
Table. Degradation rates of ethylbenzene
Degradation rate in water: |
Abiotic transformation: Hydrolysis is not a relevant degradation route for the substance.
Biotic transformation: DT50= 15 days (360 hours)
|
Degradation rate in sediment: |
DT50= 135 days (3240 hours)
|
Degradation rate in soil: |
DT50=30 days (720 hours)
|
Degradation rate in air: |
DT50=36.14 hours DT50 (for reaction with hydroxyl radicals)= 1.8 days |
Based on the data summarized here, ethylbenzene is considered to degrade rapidly via abiotic or biotic degradation paths.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
