Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
2-tert-butylaminoethyl methacrylate is not stable under adsorption/desorption test conditions. The ability of 2-tert-butylaminoethyl methacrylate to adsorb to soil and sediment is therefore estimated using the validated calculation model KOCWIN.
Soil adsorption coefficients (Koc) were calculated of 82.2 and 97.4 L/kg using respectively the molecular connectivity index and log Kow as starting point for the calculations. The average of 89.8 L/kg of the two calculated Koc values is used for riks assessment purposes. This low Koc value indicates that 2 -tert-butylaminoethyl methacrylate has a low tendency to adsorb to soil, sediment or sludge.
Key value for chemical safety assessment
- Koc at 20 °C:
- 89.8
Additional information
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.
