Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Benzene, C10-13-alkyl dervis., is a readily biodegradable substance (see section 5.2.1). No hazard was identified for aquatic organisms (acute and long-term studies available in fish, aquatic invertebrates and algae). Therefore, the substance is assessed as “aquatic toxicity unlikely to occur”. Thus, the hazard and exposure assessment with regard to sediment are waived.

Key value for chemical safety assessment

Additional information

Sediment toxicity is not a required endpoint for readily biodegradable substances. No data on sediment organisms are available. Equilibrium partitioning were used to determine the PNECsediment.
