Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

Endpoint summary
Administrative data
Key value for chemical safety assessment
Effects on fertility
Effect on fertility: via oral route
- Endpoint conclusion:
- no study available
Effect on fertility: via inhalation route
- Endpoint conclusion:
- no study available
Effect on fertility: via dermal route
- Endpoint conclusion:
- no study available
Additional information
The conduct of repeat-dose toxicity studies by either the oral, inhalation or dermal routes of administration was waived based on the unlikely exposure to gold metal via these routes. Bio-elution tests using artificial gastric fluid and artificial sweat showed no metal release above the limit of detection (1 µg/L). In addition, the granulometry of gold powder showed that less than 10 % of the substance passed through a 100 µm sieve hence it was considered unlikely to be significantly inhalable.
Effects on developmental toxicity
Effect on developmental toxicity: via oral route
- Endpoint conclusion:
- no study available
Effect on developmental toxicity: via inhalation route
- Endpoint conclusion:
- no study available
Effect on developmental toxicity: via dermal route
- Endpoint conclusion:
- no study available

Justification for classification or non-classification
Since there are no specific studies conducted for this endpoint, gold metal cannot be classified for the endpoint.
Additional information
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.
