Definition of the Substance

The Activated Carbon Consortium is preparing exclusively for the registration of Activated Carbon, which is defined as follows:

“Activated carbon: A porous, amorphous, high surface area material composed largely of elemental carbon”

Notes: Activated carbons have a large adsorption capacity, preferably for small molecules, and are used for purification of liquids and gases. By controlling the process of carbonization and activation, a variety of active carbons having different porosity can be obtained. Activated carbons are used mainly in granular and powdered forms, but can also be produced in textile form by controlled carbonization and activation of textile fibres. Other terms used in the literature: active carbons, active charcoals.

Steam activated carbon and Chemically activated carbon: two registrations?

During our work on the registration dossier, we have concluded that from the REACH perspective it may be necessary to regard Steam Activated Carbon (SAC) and Chemically Activated Carbon as different substances.

Therefore currently the required tests are being done on two samples (SAC and CAC separately). When the results are known, we can finally decide if SAC and CAC can be seen as one substance or must be regarded as two substances. This means we will either make one Registration for Activated Carbon, or two separate Registrations for SAC and CAC.
