Vapour pressure
Administrative data
Link to relevant study record(s)
- Endpoint:
- vapour pressure
- Data waiving:
- study technically not feasible
- Justification for data waiving:
- the study does not need to be conducted for organic peroxides
- Endpoint:
- vapour pressure
- Type of information:
- (Q)SAR
- Adequacy of study:
- key study
- Study period:
- 2018-04-09
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- results derived from a valid (Q)SAR model and falling into its applicability domain, with adequate and reliable documentation / justification
- Justification for type of information:
- The experimental determination of the vapour pressure of the test item Dibutyl peroxydicarbonate is technically not feasible because the substance decomposes during testing. However, as a vapour pressure value is required for exposure calculations, the QSAR estimated vapour pressure value is included as key value for chemical safety assessment.
- Qualifier:
- according to guideline
- Guideline:
- other: Guidance on information requirements and chemical safety assessment Chapter R.6: QSARs and grouping of chemicals
- Version / remarks:
- May 2008
- Principles of method if other than guideline:
- QSAR prediction using MPBPVP v1.43 of EpiSuite v4.1.
- GLP compliance:
- no
- Type of method:
- other: QSAR calculation
- Specific details on test material used for the study:
- SMILES: CCCCOC(=O)OOC(=O)OCCCC
- Temp.:
- 25 °C
- Vapour pressure:
- 0.056 Pa
- Conclusions:
- The vapour pressure of the test item was estimated by QSAR and is 0.0561 Pa at 25 °C (Modified Grain Method).
- Executive summary:
The calculated vapour pressure of Dibutyl peroxydicarbonate is 0.0561 Pa at 25 °C. The substance is considered to be in the applicability domain of the model, and despite moderate model accuracy due to the usage of an estimated boiling point for vapour pressure prediction, MPBPVP methodology is considered adequate for a regulatory conclusion. No predicted melting point was used for vapour pressure prediction because the substance is a liquid.

Description of key information
In accordance with the ECHA Guidance R.7a (Version 6.0, July 2017) this study does not need to be conducted for substances which decompose during measurement or which are unstable or explosive because determination of the vapour pressure is technically not possible. This applies to organic peroxides.
As a vapour pressure value is required for exposure calculations, the EPISuite estimated vapour pressure value of 0.0561 Pa at 25 °C is included as key value for chemical safety assessment.
Key value for chemical safety assessment
- Vapour pressure:
- 0.056 Pa
- at the temperature of:
- 25 °C
Additional information
Dibutyl peroxydicarbonate is only marketed in a form with a phlegmatiser. The test item has a self accelerating decomposition temperature (SADT) of + 5 °C.
The substance is considered to be in the applicability domain of the QSAR model, and despite moderate model accuracy due to the usage of an estimated boiling point for vapour pressure prediction, MPBPVP methodology is considered adequate for a regulatory conclusion. No predicted melting point was used for vapour pressure prediction because the substance is a liquid.
