Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
According to Column 2 of REACH Annexes IX and X (standard information requirements for substances manufactured or imported in quantities of 100 tonnes or more and 1,000 tonnes or more, respectively) of Regulation (EC) No 1907/2006, studies on the effects on terrestrial organisms do not need to be conducted, if direct and indirect exposure to the soil compartment is unlikely.
Sulphuric acid, compound with graphite is an inorganic solid, consisting of natural graphite and variable amounts of intercalated sulphuric acid.
Graphite is a naturally occurring solid substance which is insoluble in water. Due to its physico-chemical properties it is not systemically and biologically available and does not cross biological membranes. In the aquatic compartment it can be considered as an inert substance. The intercalated sulphuric acid is partially leached out by water and dissociated into the environmentally ubiquitous sulphate and hydronium ions. Due to their ionic character, they do not cross biological membranes. Sulphate is a normal biological constituent of the body, a normal biological metabolite and degradation product of sulphur-containing amino-acids. In the aquatic/soil compartment the sulphate ions are precipitated in form of naturally occurring minerals.
A study on acute toxicity (14 days) to earthworms (Eisenia fetida) performed with sulphuric acid, compound with graphite (see chapter 6.3.1 of the IUCLID dossier) further underlines the absence of toxicological effects of native products on soil organisms.
Against this background long-term toxicity testing on terrestrial arthropods is not required under Regulation (EC) No 1907/2006 (REACH).

Additional information
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.
