Description of key information

The test item is hydrolytically stable

Key value for chemical safety assessment

Additional information

The test item is a complex mixture for which the test guideline for hydrolysis is not recommended. This is not only because components could have different hydrolytic rates but also hydrolysis products can be analytically indistinguishable from their starting material.

The test item was determined* to have a water solubility value of less than or equal to 1.14 E-04 g/l; this meant the hydrolysis test would need to be performed at 5.7 E-05 g/l or lower. Therefore, it was considered that the solution concentration required for the test was impractically low to perform the test as individual components would be much lower than this.

The main functional groups in the test item are thiadiazoles and hydroxyls. Neither of these readily hydrolyse at environmentally relevant temperatures and pHs, so it would be expected that the test item is hydrolytically stable.
