Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
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.
The test substance is an organic clear colorless viscous liquid with a melting temperature of -46ºC. A boiling point could not be determined as reaction and/or decomposition of the test substance was observed at > 200°C.The reported relative density is 1.22 and the vapour pressure is 7.9E-5 Pa at 20ºC. The estimation of the partition coefficient by the HPLC method results in a log Pow of 1.7 at 25ºC. The test substance is soluble at 13.7 g/L. The test substance has a flash point of 152ºC, an auto-ignition temperature of 360ºC and a dynamic viscosity of 1153 mm2.s.
The test substance does not contain any ionizable functionality indicating that a dissociation constant study is not required. The test substance is neither flammable in contact with water or air, nor explosive. It doesn't possess oxidising properties.
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.
