Applicant's summary and conclusion
- Validity criteria fulfilled:
- not specified
- Conclusions:
- It was suggested that the loss of test substance observed at pH 4 may be due to chelation of the citrate anion with the manganese complex, and not by a hydrolysis mechanism. Therefore the pH 4 hydrolysis test was repeated using only hydrochloric acid to adjust pH (study number KE930222).
- Executive summary:
Under the test conditions the substance was found to undergo significant hydrolysis at pH4 but no hydrolysis at pH7 and 9. The results indicate that at 25 deg C the substance possesses a half-life of between 1 day and 1 year at pH4 and greater than 1 year at pH7 and 9. It was suggested that the loss of test substance observed at pH4 may be due to chelation of the citrate anion with the metal complex, and not by a hydrolysis mechanism. Therefore, the pH4 hydrolysis test will be repeated using only hydrochloric acid to adjust the pH. This work will be issued in a separate report.
