Description of key information

The log partition coefficients for the rosin ester substances range from 2.44 - >6.5.

The partition coefficient of resin acids and rosin acids, esters with diethylene glycol has been determined to be greater than 4.38E+03 at 22.0 ± 0.5°C, log Pow > 3.64.

Key value for chemical safety assessment

Additional information

Three GLP-compliant studies, one conducted according to OECD Method 107 (Safepharm Laboratories Limited, 1997a), and two conducted

according to OECD Method 117 (Inveresk Research, 2003a; Case Consulting, 1998a), were provided for Resin acids and rosin acids, esters with diethylene glycol.
