Materials and methods

Principles of method if other than guideline:
The UVCB substance as complex substance is classified by applying the rules for classification of mixtures (EU CLP regulation). The classification
criteria (as set out in EU CLP regulation) can be used to estimate effects derived from that classification/hazard.
Test type:
other: calculation based on mixture toxicity rules

Results and discussion

Any other information on results incl. tables

The calculated classification via mixture rules resulted in "Acute toxicity (oral): category 4", triggered by lead compounds with total quantity > 70% for worst case.

Applicant's summary and conclusion

Interpretation of results:
Toxicity Category IV
Migrated information Criteria used for interpretation of results: other: mixture toxicity rules
UVCB is classified for Acute toxicity oral category 4 H332
Executive summary:

The tool provided a conclusive "Acute toxicity (oral) Cat4" of the UVCB sample, derived on basis of the mixture toxicity rules for a worst case across industry.
