Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Graphite, acid-treated is an inorganic solid, consisting of natural graphite and variable amounts of either intercalated nitric acid or acetic acid. The main component – graphite - is a naturally occurring inorganic solid substance which is insoluble in water. Due to its physico-chemical properties, i.e. absence of lipophilic functional groups which would enhance lipid (fat) solubilisation properties and therefore facilitate the uptake into the organism, graphite itself can be regarded as not bioaccumulative and harmless.
The intercalated acid (nitric or acetic acid) and the intercalated ions (nitrite/nitrate, acetate) are partially leached out by water. The partially leached out ions are – due to their ubiquitous character – subject to ready biodegradation processes and are therefore not bioaccumulative.
Against this background bioaccumulation of graphite, acid-treated can be excluded.
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.
