Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Additional information

The half-life in air for the reaction with hydroxyl radicals was estimated to be 4.09 h with Aopwin v1.92. Atmospheric degradation is not expected to play a major role in the environment as emissions to air are not expected and volatilisation is small. Phototransformation in water and soil have not been assessed as these are not standard requirements in Annex IX of the REACH Regulation. 2 -tert-butylaminoethyl methacrylate (TBAEMA) reacts quickly with water (hydrolysis) to form N-tert butyl, N-hydroxyethylamine (CAS no: 4620-70-6) and methacrylic acid (CAS no: 79-41-4). The hydrolysis results of a structurally strongly related substance i.e. N,N-Dimethylaminoethyl Methacrylate (DMAEMA, CAS no: 2867-47-2) were used for read across to TBAEMA.

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).
