Materials and methods
- Principles of method if other than guideline:
- Acute dermal toxicity potential of the UVCB substance was determined by classifying based on the Mixture rules from EU CLP (additivity formula of classified components to derive hazard class) and back calculation to the corresponding acute toxicity range estimate.
Test material
- Details on test material:
- Reasonable worst-case across industry, as reported in Section 1.2.
Representative samples for mineralogical information is provided in IUCLID Section 4.23.

Applicant's summary and conclusion
- Interpretation of results:
- not classified
- Remarks:
- Migrated information
- Executive summary:
The study provided a conservative estimate of the effect concentration, derived on basis of the classification outcome (mixture toxicity rules) from a reasonable worst-case sample of the substance 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.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
