Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

- Results:
- Via Si-NMR and HPLC investigations it could be shown that the test itm Ethanol, 2,2'-oxybis-, reaction products with 3-(triethoxysilyl)-1-propanamine is not stable in water. It immedately undergoes condensation reaction that form "-Si-O-Si" moieties with hieg polymerization degree and liberate the diethylene glycol amount, that was initially added for reaction with 3-(triethoxysilyl)-1-propanamine.
Thus analysis of the test item Ethanol, 2,2'-oxybis-, reaction products with 3-(triethoxysilyl)-1-propanamine is not possible in aqueous solution. - Conclusions:
- Via Si-NMR and HPLC investigations it could be shown that the test itm Ethanol, 2,2'-oxybis-, reaction products with 3-(triethoxysilyl)-1-propanamine is not stable in water.

Additional information
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.
