Description of key information

Adsorption/Desorption

Adsorption to solid soil phase is not expected. For 2,2'-(ethylenedioxy)diethanol log Koc values for the uncharged molecule were calculated to be 1 and -0.08975 when based on the MCI method and log Kow, respectively. For 3,6,9-trioxaundecane-1,11-diol log Koc values for the uncharged molecule were calculated to be 1 and -1.2869 when based on the MCI method and log Kow, respectively.

Henry's law constant

The test substance will not evaporate into the atmosphere from the water surface. For CAS 112-27-6, the Henry's law constant was calculated to be 3.20E-006 Pa·m³/mole based on the Bond Contribution Method. For CAS 112-60-7, the Henry's law constant was calculated to be 4.97E-008 Pa·m³/mole based on the Bond Contribution Method.

Distribution modelling

The two main constituents are predicted to be primarily present in water (100%).
