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 guidance section 3.7.2 pg 322ff). The classification
criteria (as set out in EU CLP Guidance Annex I: 3.7.1 pg 322) 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 > 0.3% for worst case.
Applicant's summary and conclusion
- Interpretation of results:
- Toxicity Category IV
- Remarks:
- Migrated information
- 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.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
