Description of key information
In a US guideline study, moderate irritation was observed following a single 24-hr semi-occluded application of tetraammineplatinum dichloride to the intact or abraded skin of three rabbits (Nicholas and Jones, 1977a).
In a US guideline study, instillation of tetraammineplatinum dichloride (0.1 g) to the right eye of eight rabbits for 5 min or 24 hr caused irritation which was fully reversible within 7 days (Nicholas and Jones, 1977b).
No relevant respiratory tract irritation data were identified.

- 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).

- Category 2 (irritating to eyes) based on GHS criteria

- Executive summary:
In a US guideline study, the eye irritant potential of tetraammine platinous chloride was assessed in eight female New Zealand white rabbits. A group of three rabbits received a 0.1 g instillation of the powdered test material to the right eye. After 24 hr the eyes were rinsed and the animals were observed for up to 7 days. Another group of five rabbits were subject to the same procedure though the eye was rinsed after 5 minutes.
Redness and swelling of the conjunctiva occurred within 1 hr of exposure in both groups, and was fully reversible within 7 days. No effects were evident in the iris or cornea within the observation period. No differences in the severity of the conjunctival effects were apparent for the two exposure times.
Based on the results of this study, the test material should be classified as an eye irritant (category 2) under EU CLP criteria (EC 1272/2008).

Additional information
No relevant irritation/corrosion human data were identified. No in vitro skin or eye irritation studies were identified, or are required, as reliable in vivo studies are already available.
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 for signs of erythema/eschar formation and edema 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 for intact and abraded skin) (Nicholas and Jones, 1977a). As the test sites were only assessed 48 hr after patch removal, it was not possible to calculate mean erythema/eschar and oedema scores for the six animalsand to give a definitive classification interpretation according to EU CLP criteria (EC 1272/2008). However, the moderate irritant effects were only observed to be reversible in one animal within the observation period.Hence, it is considered precautionary to classify the test material as a skin irritant (Category 2).
In a US guideline study, the eye irritant potential of tetraammine platinous chloride was assessed in eight female New Zealand white rabbits. A group of three rabbits received a 0.1 g instillation of the powdered test material to the right eye. After 24 hr the eyes were rinsed and the animals were observed for up to 7 days. Another group of five rabbits were subject to the same procedure though the eye was rinsed after 5 minutes.

No effects were evident in the iris or cornea within the observation period. No differences in the severity of the conjunctival effects were apparent for the two exposure times (Nicholas and Jones, 1977b). Based on the results of this study, the test material should be classified as an eye irritant (category 2) under EU CLP criteria (EC 1272/2008).
No respiratory tract irritation data were identified.
Justification for classification or non-classification
Based on the results of the available skin and eye irritation studies (in rabbits), tetraammineplatinum dichloride should be classified as a skin irritant (category 2) and for eye irritation (category 2), according to EU CLP criteria (EC 1272/2008).
