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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

EC number: 266-967-8 | CAS number: 67711-91-5 Product of smelting roaster calcines concentrates or cement copper with flux in reverberatory or electric furnaces. Composed primarily of copper and copper, iron and lead sulfides with minor sulfides of other metals.
Endpoint summary
Administrative data
Description of key information
Key value for chemical safety assessment
Skin sensitisation
Endpoint conclusion
- Additional information:
Results from calculated classification (using mixture toxicity rules) are supported (WoE) by additional consideration from physico-chemical properties of the UVCB substance.
In case of Grade 1 , no sensitizing species (such as Ni or Co) present in amount higher than 0.9%
In case of Grade 2, sensitizing species from Co or Ni may be typically present in higher amounts. Dermal bio elution data (see IUCLID 7.1.2) however demonstrated that amounts released by a worst-case Matte Grade 2 would be below classifcation limit. Details on the approach and calcualtions can be found in IUCLID 7.1.2 and the Explanatory paper attached to Summary Toxico Info (IUCLID 7)
Migrated from Short description of key information:
- complex metal containing substance
- solubility of constituents in water is poor
- classification based on mixture toxicity rules
Respiratory sensitisation
Endpoint conclusion
- Additional information:
Results from calculated classification (using mixture toxicity rules) are supported (WoE) by additional consideration from physical and chemical properties of the UVCB substance.
In none of the grades, respiratory sensitizer are present in amounts > or equal 1%.
Justification for classification or non-classification
Grade 1 & 2 Copper matte:
Skin Sensitization: not classified
Respiratory Sensitization: not classified
See end-records and discussions above (+ IUCLID 7 Summary) for detailed justifications
The tested sample was representative for a Typical across industry (for all grades), defined within the concentration ranges outlined under IUCLID section 1.2
