Description of key information

The substance is hydrolytically stable at pH 7 and 9, but tends to be hydrolytically unstable in acidic environments tested at pH 4.

Key value for chemical safety assessment

Additional information

The hydrolysis properties of the test item FAT 40849/A TE were tested in a valid GLP study in accordance with EU Method C.7. The substance was found to be hydrolytically stable at pH 7 with a predicted half-life >1 year at 25 °C. The half-life could not be accurately determined at pH 4, but the substance tended to be hydrolytically unstable under acidic conditions. At pH 9, the substance was hydrolytically stable and the predicted half-life at 25 °C was 157 days. It is concluded that FAT 40849/A TE tends to be hydrolytically stable under relevant environmental conditions with a tendency for less stability in acidic environments.
