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.
