Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
- complex metal containing substance
- classification derived using CLP mixture toxicity rules
- solubility of metal constituents
Toxicity to reproduction: other studies
Additional information
The UVCB substance is a complex metal containing substance. Each individual (metal) constituent of this UVCB substance can release soluble ions that can contribute (as ‘relevant’ component) to the mixture toxicity. With knowledge of the elemental composition (IUCLID section 1.4 & 1.2) and mineralogical information on a representative sample (IUCLID Section 4.23), the mixture toxicity rules (EU CLP Guidance Annex I: 3.7.3, and cut-off/Additivity formula Table 3.7.2.) was used to calculate the classification of the UVCB substance.
The Meclas tool was used to automatically calculate the classification of the intermediate. The tool is based on a database containing the human and environmental classification for each component relevant for classification. The information on the representative mineralogical composition (distribution pattern for each constituent of the UVCB substance) is furthermore incorporated into the tool, so that the elemental composition (in % Total element) is automatically converted into % w/w of compounds/species that are relevant for applying the mixture rules.
Justification for classification or non-classification
- Please refer to IUCLID section 13 for detailed MeClas printouts with the specified input concentrations and resulting classification. Please visit www.meclas.eu for more information about the tool. MeClas tool version used: 2.5
Reproductive toxicity: Category 1A (driven by Pb)
The classification derived is applicable to all types of copper slimes.
The tested sample is representative for copper slime, defined within the concentration ranges outlined under IUCLID section 1.2 (taking typical across companies)

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.
