EC number: 696-026-0
CAS number: 1395383-69-3
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
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.
