Conclusions:
Taken together, the partition coefficient is seen to be below -1.0.
Executive summary:

The test substance ”Guanidinoacetic acid – Mother liquor“ was to be assessed for its partition coefficient. An experimental determination of the partition coefficient following the given methodology is not useful due to the test items composition and the limitation of the recommended method; therefore an estimation based on QSPR calculations and literature was done under consideration of the values given in the literature.


Taken together, the partition coefficient is seen to be below -1.0.

Description of key information

The Partition coefficient was estimated taking data from ECH, experimental literature data and QSAR-Calculations (Chemicalize and Epi-Suite) into account. 

Key value for chemical safety assessment
