Description of key information
In a guideline study (OECD TG 404), to GLP, tetraammineplatinum(II) hydrogen carbonate was very slightly irritating to the clipped skin of one of three rabbits following a 4-hr occlusive application; no irritation potential was observed in the other two animals (Berthold, 1997b).
In a guideline study (OECD TG 405), to GLP, tetraammineplatinum(II) hydrogen carbonate produced slight irritation following instillation of the test material (0.1 mL) to the eyes of three rabbits. Effects in one animal persisted until the end of the observation period, though the development of these findings indicated a tendency to reversibility (Berthold, 1997c).
No relevant respiratory tract irritation data were identified.

- Executive summary:
In an OECD Test Guideline 404 study, conducted according to GLP, a 4 hour, occlusive application of tetraammineplatinum(II) hydrogencarbonate (0.5 g moistened with 0.14 mL water) was made to the clipped skin of three male white Russian rabbits. After 4 hours, the dressings were removed and the skin sites assessed for signs of irritation (edema and erythema/eschar) at 1, 24, 48 and 72 hours.
Erythema (including eschar) and edema (both very slight) were observed in one of the three animals after 48 and 72 hr respectively. Effects were reversible within 9 days of application. No signs of irritation were apparent in the other two animals. The test material produced a primary dermal irritation index of 0.3 [maximum total score = 8.0] (mean of scores at 1 -72 hr after application)and was classified as non-irritant to rabbit skin according to the Draize classification system. Systemic toxicity was not observed after dermal application of the test substance and the general condition of the animals was unaffected.
Based on the results of this study, the test material does not require classification as a skin irritant according to EU CLP criteria (EC 1272/2008).

- Irritant / corrosive response data:
- Diffuse corneal opacity was observed in two animals 48 hours after application, in one animal this disappeared after 6 days while the other showed translucent opacity by day 10. The corneal area involved was greater than three quarters in both animals. The cornea of the third animal was unremarkable. Slight to moderate circumcorneal hyperemia was apparent in two animals, lasting from 2 to 6 days or 1 to 10 days after application respectively. The iris of the third animal was unremarkable. The conjunctivae of all three animals were hyperemic immediately after application. In one animal the findings had completely disappeared by day 7, while the other two animals showed worsening up until 3 or 4 days after application with the former showing reversibility by day 9 while the latter persisted the entire 21-day observation period. Swelling (including nicitating membranes) occurred in all three animals, and persisted in one animal until day 21.
- Other effects:
- The general condition of the animals was undisturbed. Conjunctival discharge was observed in all three animals at 1 hr and lasted until days 6, 8 and 21 (still present at the end of the observation period) respectively. Signs of irritancy aggravated during the course of the study and one animal showed an irreversible effect in the course of the 21 day observation period. Nevertheless, according to the study report "the development of the findings towards the end of the study indicates a tendency to reversibility" and thus do not justify a diagnosis of "severe eye lesions".
- Interpretation of results:
- Category 1 (irreversible effects on the eye) based on GHS criteria
- Conclusions:
- In a guideline study (OECD TG 405), to GLP, tetraammineplatinum(II) hydrogencarbonate produced slight irritation following instillation of the test material (0.1 mL) to the eyes of three rabbits. Effects in one animal persisted until the end of the observation period, though the development of these findings indicated a tendency to reversibility.
- Executive summary:
In an OECD guideline study (TG 405), conducted according to GLP, tetraammineplatinum(II) hydrogencarbonate (90.1, 106.9 or 107.1 mg, representing a volume of about 0.1 mL) was instilled into one eye of each of three male white Russian rabbits. The other eye remained untreated and was used for control purposes.
Corneal irritation was observed in two out of the three animals after 2 days. Within 6 days the effects in one animal were resolved while the effects in the other animal were still present at the end of the 21-day observation period. Iris irritation was also observed in two out of the three animals, with effects lasting until days 6 and 10 respectively. Conjunctival irritation, consisting of redness, chemosis and discharge, was observed in all three animals. In two animals, this had completely resolved within 6 and 8 days respectively while the effects in the other animal persisted until the end of the observation period. The test material produced an overall eye irritation index score of 20.0 [maximum total score possible = 110] (mean of the scores 1 -72 hr) and was classified as slightly irritant to the rabbit eye according to a modified Draize classification system. The general condition of the animals was not adversely affected. In spite of the persistent effects observed in one animal, the development of these findings towards the end of the observation period indicated a tendency to reversibility.
Nevertheless, based on the persistent effects observed in one animal in this study, the test material should be classified for serious eye damage (category 1) according to EU CLP criteria (EC 1272/2008).

Additional information
No relevant human irritation/corrosion 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 an OECD Test Guideline 404 study, conducted according to GLP, 0.5 g of tetraammineplatinum(II) hydrogen carbonate (moistened with 0.14 mL water) was applied to the clipped skin of three male white Russian rabbits. After 4 hours, the occlusive dressings were removed and the skin sites assessed for signs of irritation (edema and erythema/eschar) at 1, 24, 48 and 72 hours. Erythema (including eschar) and edema (both very slight) were observed in one of the three animals after 48 and 72 hr respectively. Effects were reversible within 9 days of application. No signs of irritation were apparent in the other two animals. The test material produced a primary dermal irritation index of 0.3 [maximum total score = 8.0] (mean of scores at 1 -72 hr after application) and was classified as non-irritant to rabbit skin according to the Draize classification system. Systemic toxicity was not observed after dermal application of the test substance and the general condition of the animals was unaffected (Berthold, 1997b).
In an OECD guideline study (TG 405), conducted according to GLP, tetraammineplatinum(II) hydrogen carbonate (90.1, 106.9 or 107.1 mg, representing a volume of about 0.1 mL) was instilled into one eye of each of three male white Russian rabbits. The other eye remained untreated and was used for control purposes. Corneal irritation was observed in two out of the three animals after 2 days. Within 6 days the effects in one animal were resolved while the effects in the other animal were still present at the end of the 21-day observation period. Iris irritation was also observed in two out of the three animals, with effects lasting until days 6 and 10 respectively. Conjunctival irritation, consisting of redness, chemosis and discharge, was observed in all three animals. In two animals, this had completely resolved within 6 and 8 days respectively while the effects in the other animal persisted until the end of the observation period. The test material produced an overall eye irritation index score of 20.0 [maximum total score possible = 110] (mean of the scores 1 -72 hr) and was classified as slightly irritant to the rabbit eye according to a modified Draize classification system. The general condition of the animals was not adversely affected. In spite of the persistent effects observed in one animal, the development of these findings towards the end of the observation period indicated a tendency to reversibility (Berthold, 1997c).
No respiratory tract irritation data were identified. A new study was not conducted as it is not a REACH Standard Information Requirement.
Justification for classification or non-classification
Based on the results of the available skin irritation study (in rabbits), tetraammineplatinum(II) hydrogen carbonate does not require classification for skin irritation according to EU CLP criteria (EC 1272/2008).
On the basis of the persistent effects in one animal in the available eye irritation study, the compound is therefore classified for serious eye damage (Category 1), in line with the harmonised classification according to Annex VI of the CLP regulation.
