Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Key result
log Pow
Partition coefficient:
ca. 0.11
20 °C
> 5.33 - < 5.79
Details on results:
Vessel 1 (1:1): log Pow = 0.13
Vessel 2 (1:1): log Pow = 0.10
Vessel 3 (2:1): log Pow = -0.19
Vessel 4 (2:1): log Pow = -0.19
Vessel 5 (1:2): log Pow = 0.10
Vessel 6 (1:2): log Pow = 0.09

Due to interference, erroneous results were obtained from analysis of concentration from 2:1 octanol/water ratio. As a results log Pow was calculated using concentrations from the 1:1 and 1:2 ratios.

The log Pow of ethylene carbonate was concluded to be 0.11 following a GLP study conducted in accordance with EU method A.8, using the shake flask method.

Description of key information

The mean log Pow of ethylene carbonate was calculated to be 0.11 following a GLP study conducted in accordance with EU test method A.8, using the shake flask method (Baker, 2010).
