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.

Description of key information

The log Koc of the measured constituents(at equal or above 0.1% w/w) of sodium benzoate has been predicted using the EPISUITE v4.11 KOCWIN (2017) program, which uses methodology described by Sahljic et al., (1995) and Meylan et al. (1995). The predicted log Koc was 7.033 kg/L at neutral pH, 1.309 kg/L at pH 5.5 and 0.1194 kg/L at ph 7.4.

The koc of 7.033 was used as key value for the assessment because being the highest among them makes the reult more conservative.
