Materials and methods
- Principles of method if other than guideline:
- The potential of the UVCB substance to be eye irritant was established by classifying the complex metal substance based on Mixture rules from EU CLP (summation and/or additivity of classified components to derive Hazard class). The classification criteria (as set out in EU CLP Guidance Annex I: 3.3.2.2 pg 247) can be used to estimate effects.
- GLP compliance:
- no
- Remarks:
- other quality assurance

Results and discussion
In vivo
- Irritant / corrosive response data:
- irritant (estimated response)
Any other information on results incl. tables
The calculated classification via Additivity method resulted in "Serious eye damage / eye irritation: category 2 H319”, driven by Cu(I) species (cat 2 eye irritant) that, in both Grades, can be present in amounts > than 10%.
Applicant's summary and conclusion
- Interpretation of results:
- Category 2A (irritating to eyes)
- Remarks:
- Migrated information predicted effect Criteria used for interpretation of results: EU
- Conclusions:
- Study can be used to establish eye irritation/serious eye damage potential of the UVCB substance.
- Executive summary:
The study provided an estimate of the Eye Irritation/serious eye damage effect, derived on basis of the Classification outcome (Mixture toxicity rules) from a typical across industry as defined in IUCLID section 1.2/1.4/4.23.
The result is applicable to Grade 1 and Grade 2, 3 and 4 Copper scales that fall under the defined concentration ranges (IUCLID section 1.2).
The result is furthermore supported by (WoE) consideration from chemical & mineralogical information (IUCLID 4.23) showing that significant amount of Eye Irritant/corrosive Cu(I) species could be detected in representative samples of both grades (for Grade 2, Total Cu >80% were considered).
Water solubility test furthermore confirmed that the UVCB has low solubility, except for Si, Na, K, Ca and Cu where these constituents/species solubilised (at high loading of 5g/100ml and after ca. 14 -16 days) -with pH observed remaining at ca 9 or ca 7 (ie not exceeding to extremes <2 or >11,5).
