Description of key information

The substance is considered to be hydrolytically stable at pH 4 and 7. Hydrolysis of the ester-bond was observed at pH 9.0.

Key value for chemical safety assessment

Additional information

The substance is considered to be hydrolytically stable at pH 4 and 7. Hydrolysis of the ester-bond was observed at pH 9.0. It is recognised that the nature of the test item is a UVCB, with many different chemical structures present in the substance, so it would be scientifically impracticable to make a detailed analytical evaluation of the exact chemical hydrolytic products. Hence Tier 2 studies cannot be performed.
