Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
A hydrolysis study is technically not feasible as the test substance is highly insoluble in water.
Activated Carbon - High Density Skeleton (AC-HDS) is a refractory material and not amenable to break down by any natural chemical or enzymatic processes.
AC-HDS is only broken down under extreme conditions - such as heating under reflux with concentrated sulphuric acid/nitric acid mixtures - when the carbon will eventually oxidise to CO2. AC-HDS cannot be rendered into a soluble form capable of being absorbed. Therefore AC-HDS cannot find its way to any cell site where it could conceivably be biodegraded. Moreover, testing the biodegradation is not feasible because the substance is not soluble in water.
The bioaccumulation study is waived because the substance has no log Kow (substance is an inorganic substance or can be considered to behave as an inorganic substance). Also the substance size will hamper passing membranes as the substance consists of particles with sizes > 0.5 µm. The particles are not soluble in water.
Adsoprtion/desorption studies are technically not feasible as the substance is not soluble in water or in organic solvents; and analysis is not possible because no distinction between C of AC-HDS and C of sediment/soil can be made in the analysis. Furthermore AC-HDS consists largely of elemental carbon and is chemically inert. No further biodegradation will occur.
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.
