Description of key information

The log partition coefficients for substances in the category Rosin, hydrogenated rosin and their salts range from 0.74 to >6.5.


The log partition coefficient of Resin acids and rosin acids, potassium salts ranges from 3.1 to 5.9 in unbuffered media; in media adjusted to pH 2 log Pow range from 3.0 to >6 (7.0).



Key value for chemical safety assessment

Additional information

A GLP-compliant study, conducted according to OECD Guideline 117 (HPLC Method), was provided for Resin acids and Rosin acids, potassium salts (Inveresk Research, 2003a)
