Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information
The log Koc of 2-phenoxyethanol was determined as 1.61 at 20°C, the Koc was determined as 40.74 L/kg.
Key value for chemical safety assessment
- Koc at 20 °C:
- 40.74
Additional information
The adsorption coefficient (Koc) onto soil and sewage sludge of 2-phenoxyethanol (purity 99.9%) was determined using HPLC method, according to OECD Guideline 121 and EC Guideline part C.19 (BASF AG, 2001). The test was performed at pH 6, as 2-phenoxyethanol is a weak acid and is un-dissociated at this pH. The adsorption coefficient for 2-phenoxyethanol is 40.74 L/kg (equals log Koc of 1.61). This value is supported by a QSAR calculation yielding a log Koc value of 1.083 (BASF AG, 2007). From the log Koc value, a low adsorption potential of 2-phenoxyethanol on solid materials can be expected.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
