Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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