Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Due to the physico-chemical properties of graphite, acid-treated it can be expected that transport within the three environmental compartments will not occur. Volatilisation from water or soil can also be excluded for graphite, acid-treated.Given the fact that the intercalated acid (nitrogen acid or acetic acid) and/or the intercalated ions (nitrite/nitrate, acetate) can partially be leached out by water, it can be concluded that water is the main target compartment.
The main component – graphite - is a naturally occurring inorganic solid substance which is insoluble in water. Its physico-chemical properties also prevent the adsorption to organic matter in the soil or sediment.The partially leached out acid will dissociate into the naturally ubiquitous hydrogen and nitrate or acetate ions – the hydrogen ions will contribute to the local pH and are potentially mobile whereas the nitrite/nitrate or acetate ions will either be taken up by plants or are subject to a subsequent biodegradation process. Given the polar nature of the ions an adsorption to organic matter in the soil or the sediment can be excluded. Its high water solubilties prevents the occurrence of geoaccumulation.
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.
