Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
In contact with water 2-dimethylaminoethyl methacrylate will hydrolyse slowly.
Key value for chemical safety assessment
Additional information
The hydrolyses of 2-dimethylaminoethyl methacrylate was measured according to OECD guideline 111. The preliminary test showed that 2-dimethylaminoethyl methacrylate was not decomposed at pH4 and 50°C in water after 5 days. However, at pH 7 and 9 the test substance decompose at 25 °C with a half-life of t1/2 = 4 days and t1/2 = 3.3 hours, respectively. Products by hydrolyses were methacrylic acid (CAS# 79-41-4) and 2-dimethylamino ethanol (CAS# 108-01-0). These results were confirmed by another OECD 211 guideline study. The hydrolyses was measured at 40 °C and showed a half-life at pH 4, 7 and 9 of 658 h, 12.4 h and 1.0 h, respectively.
In conclusion, in contact with water 2-dimethylaminoethyl methacrylate will hydrolyse slowly.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
