Water solubility
Administrative data
Link to relevant study record(s)
- Endpoint:
- water solubility
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- December 2018–January 2019
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.6 (Water Solubility)
- Deviations:
- no
- GLP compliance:
- no
- Type of method:
- column elution method
- Specific details on test material used for the study:
- SOURCE OF TEST MATERIAL
- Source and lot/batch No.of test material: Pergan GmbH, batch no. 1271219-01
- Expiration date of the lot/batch: Minimum 6 months
- Purity test date: 13/11/2018
STABILITY AND STORAGE CONDITIONS OF TEST MATERIAL
- Storage condition of test material: Maximum temperature +15 °C, in tightly sealed orginal container
- Stability under test conditions: Stable
TREATMENT OF TEST MATERIAL PRIOR TO TESTING
- Treatment of test material prior to testing: None - Key result
- Water solubility:
- < 0.6 µg/L
- Conc. based on:
- test mat.
- Temp.:
- 20 °C
- Remarks on result:
- not determinable
- Remarks:
- water solubility is below the the LOQ of 0.6 µg/L
- Conclusions:
- The water solubility of bis(4-tert-butylcyclohexyl) peroxydicarbonate was determined using the column elution method. Stable concentrations at or above the LOQ of 0.6 µg/L could not be determined. Therefore, the water solublity is < 0.6 µg/L. Bis(4-tert-butylcyclohexyl) peroxydicarbonate is essentially insoluble in water.
- Executive summary:
The water solubility of bis(4-tert-butylcyclohexyl) peroxydicarbonate was determined using the column elution method. Stable concentrations at or above the LOQ of 0.6 µg/L could not be determined. Therefore, the water solublity is < 0.6 µg/L. Bis(4-tert-butylcyclohexyl) peroxydicarbonate is essentially insoluble in water.
Reference
Description of key information
Bis(4-tert-butylcyclohexyl) peroxydicarbonate is considered to be insoluble in water, based the column elution method consistently producing values below the LOQ of 0.6 µg/L.
Key value for chemical safety assessment
- Water solubility:
- 0.6 µg/L
- at the temperature of:
- 20 °C
Additional information
Older attempts to determine the water solubility of bis(4-tert-butylcyclohexyl) peroxydicarbonate are considered invalid due to significant methodological deficiencies. A recent study employing the column elution method (Hüben, 2019) could not detect the substance at or above the LOQ of the analytical method of 0.6 µg/L. Bis(4-tert-butylcyclohexyl) peroxydicarbonate is therefore essentially insoluble in water.
