- not classified
- Remarks:
- Migrated information Criteria used for interpretation of results: EU
- Conclusions:
- The acute median lethal percutaneous dose (LD 50 ) to male rats of the test item was found to be: greater than 5000 mg/kg bodyweight.
- Executive summary:
Ten male rats were treated with The test item at a dosage level of 5 g/kg bodyweight.
There were no mortalities. Signs of reaction to treatment, observed shortly after dosing, consisted of slight lethargy only, which persisted for three days. One rat showed slight erythema on the fourth day of treatment only. This rat and another were observed to have small, raised, brown nodules on areas on the treated sites on the day after treatment only. Bodyweight increases were normal compared with the controls. Autopsy findings were normal.
CONCLUSION: The acute median lethal percutaneous dose (LD 50 ) to male rats of gold 4 N was found to be: greater than 5000 mg/kg bodyweight.
