Applicant's summary and conclusion
- Conclusions:
- The acute dermal toxicity of celery ketone was assessed using a group of ten male rabbits. The LD50 was calculated as being greater than 5.0 g/kg by the method of Litchfield and Wilcoxon.
- Executive summary:
The acute dermal toxicity of celery ketone was assessed using a group of ten male rabbits dosed by skin application at 5.0 g/kg in a method similar to OECD TG 402 (no guideline specified). The LD50 was calculated as being greater than 5.0 g/kg by the method of Litchfield and Wilcoxon. Thes test article was considered to be not toxic to the skin.
