Introduction
No determination was possible according to Method C7 Degradation – Abiotic Degradation, Hydrolysis as a Function of pH of Commission Regulation (EC) No 440/2008 of 30 May 2008 and Method 111 of the OECD Guidelines for Testing of Chemicals, due to the following reason:
- The test item is a complex reaction mixture. The test is not appropriate for complex reaction mixtures.
Method
Therefore, the hydrolytic stability was estimated using thecomputer-based specialist estimation software, HYDROWIN, version 2.00 (September 2008), © 2000 U.S. Environmental Protection Agency.
The substance was modelled without the zinc atom as the per EPIsuite recommendations.
Results
Using the software, the hydrolytic stability has been estimated. The results are presented in attachment "Attachment 1".
Conclusion
Using a computer-based atom fragment contribution method, HYDROWIN, version 2.00 (September 2008), © 2000 U.S. Environmental Protection Agency, the hydrolytic stability has been estimated. The results are presented in attachment "Attachment 1".
