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.

Additional information

According to column 2 of the REACH Annex IX further testing is not necessary if the substance has an intrinsic low bioaccumulation potential. As (N-Morpholinomethyl)-triethoxysilane is hydrolytically unstable and reacts spontaneously with air humidity and with water under formation of (N-Morpholinomethyl)-silantriol and ethanol the bioaccumulation potential has to be assessed for the hydrolyses products. Ethanol does not bioaccumulate as is well known in the scientific literature. The hydrolysis product (N-Morpholinomethyl)-silantriol has an estimated logKow of << -2 (EPISUITE 4.0, see CSR appendix), i.e. far below the threshold value of 4.5 for which bioaccumulation is expected.
