Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Materials and methods

Principles of method if other than guideline:
Repeated dose toxicity potential of the UVCB was determined by classifying based on Mixture rules from EU CLP (additivity formula of classified components to derive hazard class). The classification criteria were used to estimate effects.

Any other information on results incl. tables

According to MeClas, the substance is classified as STOT-RE Cat. 1 - H372.

Applicant's summary and conclusion

Conclusions:
Good quality study with result derived on basis of the classification outcome (mixture toxicity rules) from a conservative, worst-case sample of the substance (max. of max for As, Cd, Co, Pb, Ni, Sb, and max. of typicals for other elements) across industry as defined in IUCLID section 1.2/4.27 for all grades, using mineralogical information from the representative sample.The analysed UVCB sample is classified for STOT-RE Cat. 1.
Executive summary:

The study provided a conservative estimate, derived on basis of the classification outcome (mixture toxicity rules) from a conservative, worst-case sample of the substance (max. of max. for As, Cd, Co, Pb, Ni, Sb, and max. of typicals for other elements, across industry as defined in IUCLID section 1.2/4.27), using mineralogical information from the representative sample.


 


Validity of the model used:


1. Defined endpoint: the endpoint is a REACH compliant defined endpoint


2. Unambiguous algorithm: EU CLP guidance based summation formula to determine classification, followed by back-calculation to related hazard criteria


3. Applicability domain: applicable to classify complex metal containing materials. 


4. Mechanistic interpretation - metal species: the tool translates the elemental composition into a mineralogical composition relevant for classification
