Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

The following vapour pressures were calculated for the components of Resin 835 A at 25 °C:
- Dehydroabietic acid, CAS No. 1740-19-8, 54 % (w/w) of Resin 835 A: 0.000038 Pa
- Dihydroabietic acid, CAS No. 19407-37-5, 25 % (w/w) of Resin 835 A: 0.000105 Pa
- Pimaric acid, CAS No. 127-27-5, 4 % (w/w) of Resin 835 A: 0.000016 Pa
- Isopimaric acid, CAS No. 5835-26-7, 3 % (w/w) of Resin 835 A: 0.000075 Pa

Key value for chemical safety assessment

Vapour pressure:
0 Pa
at the temperature of:
25 °C

Additional information

A mean vapour pressure of <0.0001 Pa at 25 °C was estimated from the vapour pressures of the components of Resin 835 A for the use in models for exposure estimation.
