Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Koc: 22.6 L/Kg
Key value for chemical safety assessment
- Koc at 20 °C:
- 22.6
Additional information
No experimental studies investigating the adsorption/desorption potential of 2-(2-ethoxyethoxy)ethyl acetate (CAS 112-15-2) are available. Therefore, the adsorption/desorption potential was estimated using the EPA OPERA model to give a reliable value within the Applicability Domain. The Koc values of 22.6 indicates that the substance has a low potential to adsorb to organic soil and sediment particles.
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).
