Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- The acute oral LD50 value of dihydrogen hexahydroxyplatinate compound with 2-aminoethanol (1:2) was determined to exceed 2000 mg/kg bw following gavage administration in rats.
- Executive summary:
In an OECD Test Guideline 423 study, to GLP, dihydrogen hexahydroxyplatinate compound with 2-aminoethanol (1:2) was studied for acute toxicity after single oral administration in Sprague-Dawley rats.
The test substance was administered by stomach tube at a dose of 2000 mg/kg bw to groups of rats (3/sex). No mortality was observed and there were no clinical signs or body weight changes at the end of the 14-day observation period. Subsequent necropsy revealed no gross abnormalities.
The acute oral LD50 value of dihydrogen hexahydroxyplatinate compound with 2-aminoethanol (1:2) was determined to exceed 2000 mg/kg bw.
