Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Additional information

Based on the available study concerning the Acute Toxicity via Oral route, charcoal has beneficial effects (2.5 g/kg b.w./day) on Zanzibar red colobus monkey i.e. higher birth rate and population densities.

Also, according to the testing results for the Acute Inhalation lethal concentration LC50 > 4.97 mg/L.

Finally, as oral and inhalation routes of exposure are more relevant and data for these have been provided, testing for acute dermal toxicity is therefore waived based on this information. Furthermore, dermal toxicity of the substance is insignificant, based and on its low water solubility and the granulometry of the subsstance.

Justification for classification or non-classification

Based on the available data for acute toxicity and the physical and chemical properties of the substance, we can conclude that charcoal is not responsible for classification.
