- not classified
- Remarks:
- Migrated information Criteria used for interpretation of results: EU
- Conclusions:
- The median lethal dose of Cinnamon leaf oil after dermal application to rabbits is: LD50 (rabbit) > 5000 mg/kg. Based on these results the substance does not have to be classified according to the EU classification criteria outlined in 67/548/EEC and 1272/2008.
- Executive summary:
The acute dermal toxicity of Cinnamon leaf oil in the rabbit was assessed. 10 Rabbits were treated with Cinnamon leaf oil by dermal application of 5000 mg/kg. The animals were observed and mortality and skin irritations were recorded. Skin irritation: moderate redness - 4/10 rabbits; marked redness - 6/10 rabbits ; moderate edema - 6/10 rabbits ; marked edema - 4/10 rabbits. No animals died during the test period. The median lethal dose of Cinnamon leaf oil after dermal application to rabbits is: LD50 (rabbit) > 5000 mg/kg. Based on these results the substance does not have to be classified according to the EU classification criteria outlined in 67/548/EEC and 1272/2008.
