Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Additional information
No relevant irritation/corrosion human or laboratory animal data were identified. However, availability considerations provide good support for the conclusion that skin and eye irritation studies can be waived.
Platinum is considered to be non-bioavailable following dermal exposure, as evidenced by transformation/dissolution and bio-elution test data. Although the bio-elution testing does not extend to the use of lachrymal fluid, the available dermal fluid data is nevertheless indicative of negligible bioavailability following exposure via the eyes.
Since a chemical is required to be bioavailable in order to induce (non-mechanical) irritation, platinum is considered incapable of inducing skin or eye irritation. Finally, for animal welfare reasons, conducting new in vivo toxicity tests is considered a last resort. Consequently, no testing for skin or eye irritation of platinum is considered justified.
No respiratory tract irritation data were identified. A new study was not conducted as it is not a REACH Standard Information Requirement. Further, platinum is not expected to reach the lungs in appreciable quantities (based on respiratory tract deposition modelling data). Thus, inhalation will not be a significant route of exposure.
Justification for classification or non-classification
No skin or eye irritation data are available for platinum. However, such effects are not expected, based on a lack of bioavailability. As such, there is no evidence to classify it for skin or eye irritation according to EU CLP criteria (EC 1272/2008).
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
