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, sodium salts ranges from 3.0 to 5.8 in unbuffered media at pH ca 7; in media adjusted to pH 2 log Pow range from 0.9 to >6 (6.6).



Key value for chemical safety assessment

Additional information
