Primary irritation index Classification
0 non-irritant
> 0-2 mild irritant
> 2-5 moderate irritant
> 5-8 severe irritant

Applicant's summary and conclusion
- Interpretation of results:
- Category 2 (irritant) based on GHS criteria
- Conclusions:
- In a US guideline study, moderate irritation was observed following a single 24-hr semi-occluded application of tetraammine platinous chloride to the intact or abraded skin of three rabbits.
- Executive summary:
In a US guideline study, the irritant potential of tetraammine platinous chloride was assessed on the intact and abraded skin of six female New Zealand white rabbits.
The test substance (0.5 g) was applied for 24-hr under semi-occlusion and assessed immediately upon removal of the patch as well as 48 hr later. Residual test material was not washed off the skin during this period. Moderate irritation was observed at both time points. Similar scores for both erythema/eschar formation and edema were reported for intact and abraded skin. The primary irritation index was calculated to be 2.8.
Mean erythema/eschar and oedema scores were below 2.3 for all six animals. However, the effects were only observed to be reversible in one animal within the 48-hr observation period.
Based on the results of this study, tetraammine platinous chloride should be classified as a skin irritant (category 2) according to EU CLP criteria (EC 1272/2008).
