Description of key information
Additional information
The parent material, 3-(triethoxysilyl)propan-1-amine, hydrolyses rapidly in water to form the substance hydrolysis product of 3-(triethoxysilyl)propan-1-amine >0.1 - <16% (EC no. 939-125-9). The hydrolytic reaction of 3-(triethoxysilyl)propan-1-amine is always accompanied by self-condensation processes (Brochier Salon et. al. 2010; Brochier Salon et al, 2008; Shi et al. 2012; Paquet et al. 2012). Therefore the substance hydrolysis products of 3-(triethoxysilyl)propan-1-amine consists of not only silanol and ethanol which are formed directly from hydrolysis, but also several condensation products, such as dimers, trimers as well as oligomeric siloxanes. Furthermore, the experimental results on removal of water show that water cannot be separated from the substance without affecting the stability or changing the substance composition (Chemetall, 2015). Taking all these into consideration the substance firstly represents already a hydrolysis product and secondly testing for further hydrolytic reactions is not possible due to the complexity and instability of the substance itself. In addition, the substance is regarded as readily biodegradable. In accordance with column 2 of Annex VIII 9.2.2.1 of Regulation (EC) No 1907/2006, testing for hydrolysis is not required if the substance is readily biodegradable.
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.
