Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
All terrestrial toxicity tests have been waived with the following statement:
2-tert-butylaminoethyl methacrylate CAS 3775-90-4 is a monomer used in the manufacture of acrylic copolymers used as ingredients in personal care and industrial products. Manufacture of the monomer and the polymers containing it, takes place outside the European Community. The 2-tert-butylaminoethyl methacrylate is typically incorporated in the polymer at up to 4% with more than >99.75 % of the monomer bound in the polymer with only <0.25 % of unbound residual monomer. The estimated remaining residual fraction is <0.01% in polymers imported into the EU is therefore <0.2 tons (<200kg). Due to the limited stability of the 2-tert-butylaminoethyl methacrylate under environmental conditions and the negligible potential for exposure in the environment it is considered justified to waive Annex IX ecotoxicity testing.
In the absence of measured data the PNECsoilcan be provisionally calculated using the equilibrium partitioning method (EPM) and this has been done as shown in the table below. According to the TGD this method uses the PNECaquaticand the soil/water partitioning coefficient as inputs.
The PNECsoilis then calculated using the equations detailed in the TGD |
|
PNECsoil |
=Ksoil-water/ RHOsoil* PNECwater*1000 mg/kg (R10-5, modified wet soil density from EUSES) |
|
|
Where: |
|
PNECaquatic |
= 0.0648 |
Ksoil-water |
= 2.9 m3/m3 |
RHOsoil |
= 1700 kg/m3(TGD) |
PNECsoil-EPM |
= 0.111 mg/kg ww |
|
= 0.125 mg/kg dw |
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.
