Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Although an hydrolysis study according to OECD 111 was performed with the substance, section 2 of REACH Annex XI mention that the hydrolysis as a function of pH study (section 9.2.2.1) does not need to be performed if the substance is an UVCB, the components may hydrolyze at different rates compounding the determination of this endpoint. Therefore, no key value for chemical assessment was determined.

Additional information

A hydrolysis study according to OECD 111 was performed with 4,4’-Isopropylidenediphenol, oligomeric reaction products with 1-chloro-2,3-epoxypropane, reaction products with butan-1-ol and 3-aminomethyl-3,5,5-trimethylcyclohexylamine. However, due to low solubility at pH 7 and pH 9 no hydrolysis rate could be determined. At pH 4, the substance was found to be relatively stable with a half-life time > 1 year.

In accordance with section 2 of REACH Annex XI, the hydrolysis as a function of pH study (section 9.2.2.1) does not need to be performed as the substance is an UVCB, the components may hydrolyze at different rates compounding the determination of this endpoint. Therefore, no key value for chemical assessment was determined.
