Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information
No vapour pressure could be determined applying the static method due to the presence of substances with a very low vapour pressure and traces or of highly volatile components, e.g. residues of solvents. Therefore, in a weight-of-evicence approach, calculated values with for typical 3 substances with the relatively highest concentration present in the substance are taken for assessment. These compounds represent about 56% of the organic part of the UVCB, and the addition of the partial pressures is considered to deliver a more realistic result than the measured values.
Key value for chemical safety assessment
- Vapour pressure:
- 0 Pa
- at the temperature of:
- 20 °C
Additional information
The following calculated values for the vapour pressure were used (20°C):
- Abietic acid, content ca. 6.5%: partial vapour pressure 1.2E-06 Pa
- Dehydroabietic acid, content ca. 40%: partial pressure 6.8E-06 Pa
- Fumarate adduct of acietic acid (=Fumaropimaric acid), content ca. 10%: partial vapour pressure 1.1E-11 Pa
It should be regognised that Ca and Mg of these acids are expected to have even lower vapour pressures due to their ionic structure.
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.
