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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

EC number: 271-802-8 | CAS number: 68608-82-2 A complex combination of hydrocarbons obtained by the alkylation of benzene with ethene. It consists primarily of ethylbiphenyls, diethylbenzenes with lesser amounts of butylbenzenes and polyethylbenzenes.

Description of key information
No long-term toxicity to fish studies are available for the test substance (‘benzene, ethylenated, by-products from’).
Key value for chemical safety assessment
Additional information
The supported uses for this substance (‘benzene, ethylenated, by-products from’) are limited to industrial closed systems and as such are not expected to lead to direct or indirect exposure to the environment. Therefore long-term fish toxicity testing for the substance is not required. However, under unlikely circumstances of accidental release (e.g., unplanned event of loss of containment), soil compartment would be the most likely receiving environmental media. Therefore, Fish, Early-Life Stage (FELS) toxicity test (test method: OECD 210) is justified to be waived. Regarding PBT assessment, based on acute toxicity to fish, daphnia, and long-term toxicity to algae, the substance meets the criterion for T. Additional study on long-term toxicity to fish is not necessary because this test is not going to provide additional useful information regarding its T classification.
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.
