- Key result
- Remarks on result:
- not determinable because of methodological limitations
- Validity criteria fulfilled:
- not specified
- Conclusions:
- The results of this study must be treated with caution. The concentration of the test substance in the test solution decreased similarly at all pH's and factors other than hydrolysis were considered as the cause of these decreases. Furthermore, the test substance has the property of polymerising in a solvent. Taking these facts into consideration it is concluded that the test substance is polymerising in water and it is therefore difficult to evaluate the hydrolysability based on the measurement of concentration.
