Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- In a guideline study, to GLP, tetraammineplatinum(II) hydrogen carbonate did not cause skin sensitisation in a Buehler test in which guinea pigs were dermally challenged with 50% of the test compound (in 1% aqueous CMC) following a 2-week induction period involving three 6-hr epicutaneous occlusive applications of an identical concentration of the test item.
- Executive summary:
The skin sensitisation potential of tetraammineplatinum(II) hydrogen carbonate was evaluated using a Buehler test in guinea pigs, conducted in accordance with OECD Test Guideline 406 and to GLP. Animals (10/sex) received three 6 -hr epictuaneous applications of the test material at 50% in 1% aqueous carboxymethyl cellulose (CMC) during a 2-week induction period .There were no skin responses to an epicutaneous occlusive challenge exposure to an identical concentration (50% in 1% aqueous CMC) 2 weeks later.
Based on the results of this study, no classification for skin sensitisation is required according to EU CLP criteria (EC 1272/2008).
