Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Additional information
After re-examination of the substance description and based on the ECHA Guidance for identification and naming of substances under REACH, the lead registrant agreed with the other SIEF members that the identifiers (CAS number and EC name) used for the toxicological, ecotoxicological and physico-chemical testing are not representative of the UVCB substance used for the testing. Consequently, the EC name Bis(2,3-epoxypropyl)cyclohexane-1,2-dicarboxylate and CAS number 5493-45-8, mentioned in the testing reports and refering to a monoconstituent substance are incorrect and should be read as 1,3-Isobenzofurandione, hexahydro-, reaction products with epichlorohydrin with CAS number 1395383-69-3, which is representative of the registered UVCB substance used effectively.
Conclusion on classification
According to the Guidance on the Application of the CLP Criteria , if the acute aquatic toxicity is >10and ≤100 mg/L, (96h LC50 (fish) = 17 mg/L, 48h EC50 (daphnia) = 71.6 mg/L, and 72h ErL50 (algae) > 56 mg/L), and as the substance is not considered to be rapidly degradable with low a potential for bioaccumulation (log Kow = 1.7), the substance should be classified Aquatic Chronic Category 3 (H412: Harmful to aquatic life with long lasting effects) according to Regulation (EC) No 1272/2008, Annex I section 4.1.
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.
