Hydrolysis
Administrative data
Link to relevant study record(s)
- Endpoint:
- hydrolysis
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 2019
- Reliability:
- 1 (reliable without restriction)
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 111 (Hydrolysis as a Function of pH)
- GLP compliance:
- yes (incl. QA statement)
- Analytical monitoring:
- yes
- Preliminary study:
- the preliminary test for zinc glycinate was conducted at 50 +/-0,5Cin buffer pH 4,7, and 9 buffer solutions for a period of 5 days .
- Test performance:
- Based on the results zinc glycinate was found hydrolytically stable in buffer pH4, pH7, pH9 buffers at 50C. It concludes that the test item half-life is greather than 1 year (t1/2>1) in buffer pH4, pH7 and pH9.

- DT50:
- >= 1 yr
- Type:
- (pseudo-)first order (= half-life)
- Remarks on result:
- hydrolytically stable based on preliminary test
- Validity criteria fulfilled:
- yes
- Conclusions:
- the preliminary test for zinc glycinate was conducted at 50 +/-0,5Cin buffer pH 4,7, and 9 buffer solutions for a period of 5 days . Based on the results zinc glycinate was found hydrolytically stable in buffer pH4, pH7, pH9 buffers at 50C. It concludes that the test item half-life is greather than 1 year (t1/2>1) in buffer pH4, pH7 and pH9.
