Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Flammability is usually seen as the ease with which a substance can burn or be ignited. However, it also includes spontaneously flammability (pyrophoricity) and ignition on contact with water.
Graphite, acid-treated is an inorganic solid, consisting of natural graphite and variable amounts of either intercalated nitric acid or acetic acid. In graphite, acid-treated there are no functional groups present which are known to exhibit pyrophoric properties, e.g. alkyl aluminium derivatives, alkyl halophosphines, alkyl metals, etc. (for further evaluation see Guidance on information requirements and chemical safety assessment – Chapter R.7a: Endpoint specific guidance; p. 124, chapter "Pyrophoricity"). Furthermore, graphite, acid-treated does not contain hydrolysis-sensitive functional groups which might lead to ignition of the substance or might lead to the release of flammable gases upon contact with water.
Long-term experience in manufacturing, handling and use of the substance further confirm that flammability is not a concern for graphite, acid-treated. Graphite, acid-treated is used as flame retardant additive for plastics and foams.
Against this background and due to the inherent properties of graphite, acid-treated (no relevant functional groups known to contribute to flammability) it can be concluded that pyrophoricity, flammability on contact with water and flammability in general are not a concern for this substance.

Additional information
Justification for classification or non-classification
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.
