Hydrolysis
The hydrolysis as a function of pH of the test material was investigated in accordance with the standardised guidelines OECD 111, EU Method C.7 and EPA OPPTS 835.2120 under GLP conditions.
The rate of hydrolysis of the test material as a function of pH was investigated at buffer solutions at pH values normally found in the environment (pH 4, 7 and 9). The test material was spiked to the solutions at a target concentration of 2.90 mg/L. For each sampling time (5 and 12 days), duplicate sterile PET vessels under vacuum were filled with 6 mL test solution and placed in the dark in a temperature controlled environment at 50.1 ± 0.2 °C.
After 5 days, a relative concentration decrease of 99, 33 and 4.7 % was observed at pH 4, pH 7, and pH 9, respectively. No hydrolysis was expected based on the molecular structure of the test material, therefore, to test whether this concentration decrease is caused by adsorption of test material on the wall of the test tube, additional samples were taken at t = 12 days.
This experiment indicates that the test material adsorbs to the container wall. This, along with the low test material concentrations used as a result of the low water solubility of the test material, results in the definitive test for hydrolysis not being technically possible.
Under the conditions of this study, hydrolysis as a function of pH cannot be determined.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
