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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

Adsorption / desorption
Administrative data
Link to relevant study record(s)
- Endpoint:
- adsorption / desorption: screening
- Data waiving:
- study scientifically not necessary / other information available
- Justification for data waiving:
- the study does not need to be conducted because the physicochemical properties of the substance indicate that it can be expected to have a low potential for adsorption
- other:
- Justification for type of information:
- Based on the physico-chemical properties; extremely low water solubility and propensity to form microsized agglomerates, bulk and nanoforms of carbon black expected to have a low potential for adsorption and studies on adsorption / desorption do not need to be conducted.
Carbon black, regardless of form is composed essentially of carbon which is ubiquitous in the environment.

Description of key information
In accordance with section 2 of REACH Annex XI, the adsorption/desorption screening study does not need to be conducted as the substance is highly insoluble in water and in organic solvents and cannot be measured analytically. Adsorption/desorption is the distribution of a chemical between soil and aqueous phase. Non-nanoforms of carbon black are substantially elemental carbon; they are inert, inorganic and contains no water-soluble groups, e.g. alcohols, ethers, or acids and is therefore insoluble in water. Carbon black is stable in water. It cannot be measured analytically in water, the determination of a distribution coefficient is technically not feasible

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.
