Description of key information
Based on the physical-chemical properties (insolubility, no vapour pressure) it is expected that non-nanoforms carbon black will not occur in air or water in relevant amounts. Also, the potential for distribution via water or air, respectively, can be dismissed. The deposition in soil or sediments is therefore the most relevant compartment of fate of carbon black in the environment. Carbon is widely distributed in nature and an essential element in the components of all living organisms.
Additional information
Carbon black (non-nanoform) is essentially elemental carbon and contains no water-soluble groups, e.g. alcohols, ethers, esters, or acids. It therefore is insoluble in water and stable against hydrolysis. It cannot further be degraded by light or light and reactive species by photodegradation in air or surface water. Carbon black is also insoluble in all organic solvents, and its vapour pressure is negligible. These physical-chemical properties are the reason why important parameters like water solubility, octanol/water partition coefficient, dissociation constant or adsorption/desorption which are relevant for environmental fate and distribution cannot be measured analytically in water or organic solvent, like octanol. Based on these properties (insolubility, negligible vapour pressure) it is expected that carbon black will not occur in air or water in relevant amounts. Also, a relevant distribution via water or air can be dismissed. The deposition on soil or sediments is therefore the most relevant compartment of fate of carbon black in the environment. However, carbon is widely distributed in nature and an essential element in the components of all living organisms.
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.
