Vapour pressure
Administrative data
Link to relevant study record(s)
- Endpoint:
- vapour pressure
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 2012
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 104 (Vapour Pressure Curve)
- Principles of method if other than guideline:
- An estimation procedure in accordance with the test method OECD Guideline 104 “OECD Guideline For The Testing Of Chemicals, adopted by the Council on 23 March 2006, Vapour Pressure” ANNEX Estimation Method newest version (Robert S. Boethling, Donald Mackay, Handbook of Property Estimation Methods for Chemicals, Lewis Publishers, year of publication 2000, Cap. 3 - Vapour Pressure, Grain-Watson Method, p. 53 – 65) was used. This method is applied for vapour pressures between 10^3 to 10^-7 mbar. This deviates from the older version published in OECD Guideline 104. It was used due to the differentiation between solids and liquids, which results in a more precise estimate.
This method uses the melting and the boiling temperatures. - GLP compliance:
- no
- Type of method:
- other: An estimation procedure in accordance with the test method OECD Guideline 104 was used.
- Key result
- Temp.:
- 20 °C
- Vapour pressure:
- <= 0.035 Pa
- Remarks on result:
- other: the calculation is based on lowest possible boiling temperature
- Conclusions:
- The calculation resulted in a vapour pressure of < = 0.035 Pa (derived by estimation procedure in accordance with the test method OECD Guideline 104).
- Executive summary:
In the Klimisch 1 non-GLP study from Kintrup (2012) the melting point (>229 °C) of the test item Reaction product of (R)-12-hydroxy-N-(2- hydroxyethyl)oleamide and maleic anhydride and sodium hydrogensulfite is between 200 °C and 300 °C and a boiling of the test item could not be determined without doubt. Therefore an estimation procedure in accordance with the test method OECD Guideline 104 “OECD Guideline For The Testing Of Chemicals, adopted by the Council on 23 March 2006, Vapour Pressure” ANNEX Estimation Method newest version (Robert S. Boethling, Donald Mackay, Handbook of Property Estimation Methods for Chemicals, Lewis Publishers, year of publication 2000, Cap. 3 - Vapour Pressure, Grain-Watson Method, p. 53 – 65) was used.
The calculation resulted in a vapour pressure of < = 0.035 Pa.
This result is considered reliable and relevant for the further risk assessment.
Reference

The calculation resulted in a vapour pressure of < = 0.035 Pa.
Description of key information
Vapour pressure (20°C): <=0.035
Key value for chemical safety assessment
- Vapour pressure:
- 0.035 Pa
- at the temperature of:
- 20 °C
Additional information
In the Klimisch 1 non-GLP study from Kintrup (2012) the melting point (>229 °C) of the test item Reaction products of ricinoleic acid with 2-aminoethanol and maleic acid and sodium hydrogensulfite is between 200 °C and 300 °C and a boiling of the test item could not be determined without doubt. Therefore an estimation procedure in accordance with the test method OECD Guideline 104 “OECD Guideline For The Testing Of Chemicals, adopted by the Council on 23 March 2006, Vapour Pressure” ANNEX Estimation Method newest version (Robert S. Boethling, Donald Mackay, Handbook of Property Estimation Methods for Chemicals, Lewis Publishers, year of publication 2000, Cap. 3 - Vapour Pressure, Grain-Watson Method, p. 53 – 65) was used.
The calculation resulted in a vapour pressure of < = 0.035 Pa.
This result is considered reliable and relevant for the further risk assessment.
