Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Endpoint summary
Administrative data
Description of key information
- complex metal containing substance
- water solubility of the substance (for metal constituents)
- classification based on mixture toxicity rules
Key value for chemical safety assessment
Additional information
Results from calculated classification (using mixture toxicity rules) are supported (WoE) by additional consideration from physico-chemical properties of the UVCB substance.
Chemistry and mineralogy of the material (see IUCLID section 4.23 chemical and mineralogical characterization) were taken into account. Substance is a paste (slime) that once dried show powder form (see picture in IUCLID section 1.4 "sampling protocol") which particle size distribution (IUCLID section 4.5) for a worst case sample (ie substance is normally dried for transport, when handled or commercialized) demonstrated that material is powder forms (inhalable and/or swallowable). Water solubility (IUCLID section 4.8) furthermore demonstrated that substance is, at least partly, moderately to fully soluble in water.
Justification for classification or non-classification
- Please refer to IUCLID section 13 or Annex I of the CSR 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
Acute toxic (oral): Category 3 H301 for grade 1
Category 2 H300 for grade 2 Major driver is Arsenic, in oxides and compounds forms
Acute toxic (dermal): not classified for all grades
Acute toxic (inhalation): Category 4 H332 (major driver is Arsenic, in oxides and compounds forms) for all grades
The tested sample is representative for copper slimes, as defined within the concentration ranges outlined under IUCLID section 1.2 (Typicals across industry)
