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.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
