- Guideline:
- OECD Guideline 105 (Water Solubility)
- Version / remarks:
- 1981
- Deviations:
- no
- GLP compliance:
- not specified
- Type of method:
- column elution method
- Key result
- Water solubility:
- 9 mg/L
- Temp.:
- 0 °C
- Remarks on result:
- other: pH is not reported
- Conclusions:
- Under the test conditions, the water solubility of the test substance tert-butyl peroxyneodecanoate was 9 mg/L (at 0 °C).
- Executive summary:
A water solubility test for the test substance tert-butyl peroxyneodecanoat (at least 90 % pure) was performed according to OECD No. 105 guideline. The test was conducted using the column-elution method suitable for water solubility values lower than 10 mg/L. The column was filled with water, sand and test substance following the OECD guideline. Five aliquots were drawn from the column after certain time frames and after pre-treatment analyzed by HPLC. Stability of the test substance during the test has also been controlled using IR spectroscopy. Results obtained showed a water solubility of 9 mg/L (at 0°C) for the tert-butyl peroxyneodecanoat.

Description of key information
Under the test conditions, the water solubility of the test substance tert-butylperoxyneodecanoate was 9 mg/L (at 0 °C). The water solubility of the test substance was estimated to be 13 mg/L at 25 °C. This value was used for the risk assessment.
Key value for chemical safety assessment
- Water solubility:
- 13 mg/L
- at the temperature of:
- 25 °C
