Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Substances in the category Rosin, hydrogenated rosin and their salts have a boiling point >360°C.
Test was terminated at 171°C and no boiling point was observed under the test conditions.
At this temperature discoloration of the test sample was observed. This phenomenon is not the consequence of mass decomposition of the substance but occurs when the resin is not correctly stored and when heating the substance in a non-inert atmosphere (due to the formation of some chromophores).
Any heating to elevated temperatures should occur under inert gas conditions to prevent darkening of the product.
Key value for chemical safety assessment
Additional information
A GLP-compliant study, conducted according to OECD Guideline 103, was provided for Resin acids and Rosin acids, reaction products with formaldehyde, potassium salt (Harlan Laboratories Ltd., 2012a)
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.
