Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Two guideline ecotoxicity studies have been conducted on cyclopentene, an OECD 201 toxicity to algae study and an OECD 202 short-term toxicity to daphnia. A reliable method of chemical analysis was not achievable for concentrations of the test item in the media or water at dosed concentrations of >10 mg/l. Any measured concentrations above 10 mg/l are concluded to be unreliable and any samples dosed at concentrations >10 mg/l cannot be reliably reproduced.
However, full tests on algae and daphnia were attempted according to the OECD guidelines with adaptations to account for the volatility of the substance. The results were inconclusive as they could not achieve consistent measured concentrations and the biological data was inconclusive. It has been concluded from these tests that ecotoxicity tests such as these are not technically feasible.
Additional information
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.
