Description of key information

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

The log partition coefficient of Resin acids and rosin acids esters with triethylene glycol is 2.44 at 20 - 25°C and pH 4.78 - 5.23.

Key value for chemical safety assessment

Additional information

A study following the EU method A.8 (shake-flask method) was used as the key study (Chilworth Technology, 2010a). The log partition co-efficient of Resin acids and rosin acids, esters with triethylene glycol is 2.44 at 20 -25

°C and pH 4.78 -5.23
