Vapour pressure
Administrative data
Link to relevant study record(s)
- Endpoint:
- vapour pressure
- Type of information:
- calculation (if not (Q)SAR)
- Remarks:
- Migrated phrase: estimated by calculation
- Adequacy of study:
- key study
- Study period:
- september 2008 to october 2008
- Reliability:
- 1 (reliable without restriction)
- Qualifier:
- no guideline required
- Principles of method if other than guideline:
- The test item is a mixture of substances showing presumably low vapour pressure properties. Using defined technics( e.g. effusion method, gas saturation method) would certainly conduct to fimsy results. The vapour pressure can then be obtained by calculation. The obtained value is a trend of the value of the vapour pressure.
- GLP compliance:
- yes (incl. QA statement)
- Type of method:
- gas saturation method
- Temp.:
- ca. 25 °C
- Vapour pressure:
- ca. 0 Pa
- Conclusions:
- The vapour pressure of LCE07101 is defined as the highest value of the P 25°C of the substances present in the test item.
The vapour pressure at 25°C of LCE07101 is equal to 6.66 x 10-5 Pa. - Executive summary:
Type of method: gas saturation method.
The vapour pressure is defined as the highest value of the P 25°C of the substances present in the test item.
The vapour pressure at 25°C of the product is equal to 6.66 x 10-5 Pa.
Reference
| Substances contained in LCE07101 | Value of P 25°C |
| 1 -eicosanol (C20) | 6.66 x 10 -5 Pa |
| 1 -docosanol (C22) | 8.17 x 10 -6 Pa |
| alkylphosphate (C20) | 8.08 x 10 -9 Pa |
| alkylphosphate (C22) | 8.08 x 10 -9 Pa |
Description of key information
The objective of this study was to determine the vapour pressure of the test item by calculation. The study was done using EPI Suite EPIWINNT software. The vapour pressure of the test item was defined as the highest value of the P25°C of the substances present as the composition of the test item.
The vapour pressure of the test item at 25°C is equal to 6.66 x 10-5 Pa.
Key value for chemical safety assessment
- Vapour pressure:
- 0 Pa
- at the temperature of:
- 25 °C
Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
