Description of key information

The vapour pressure for members of the category Rosin, hydrogenated rosin and their salts ranges from 4.8 x 10-8 mbar to <1.41 mbar at 25°C.

The vapour pressure of Resin acids and rosin acids, sodium salts is 0.6 mbar 20 Pa at 20°C, equivalent to 0.85 mbar at 25°C.

The vapour pressure of Rosin, reaction products with formaldehyde was determined to be 20 Pa at 20°C, equivalent to 0.282 mbar at 25°C.


Key value for chemical safety assessment

Additional information

A GLP-compliant study, conducted according to EU Method A.4 (static), was provided for Resin acids and Rosin acids, sodium salts (Chilworth Technology, 2010a).
