Description of key information
Hydrolysis is a common degradation route in the environment, where reaction of a substance with water with a net exchange of the X group with an OH at the reaction centre such that RX + H2O → ROH + HX. The substance non-graphitic carbon fibres does not contain hydrolysable functional groups or labile functional groups (Kollig et al., 1993; Boethling & Mackay, 2000). Therefore, hydrolysis of the substance can be excluded. In addition, by the definition of Harris, 1990 and Sijm et al., 2007 hydrolysis is defined as a chemical reaction of an organic molecule with water, whereas the test substance is inorganic. In summary, it is scientifically not justified to conduct a study on hydrolysis.
Key value for chemical safety assessment
Additional information
Non-graphitic carbon fibres within the scope of this registration consist of highly condensed carbon atoms in ring structures. The nitrogen, hydrogen and oxygen atoms which have not been driven off during manufacture (carbonisation step at temperatures of approximately 900 °C up to > 2200 °C) are only present in covalently bound form. Therefore and because of its low solubility in water hydrolysis of the substance is not 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.
