Results and discussion
Effect levels
- Sex:
- male/female
- Dose descriptor:
- LD50
- Effect level:
- > 3 038 mg/kg bw
- Mortality:
- One male exposed to 3,038 mg/kg died at 12 days. There were no other deaths.
- Clinical signs:
- other: The test material was severely irritating to the skin. Skin changes at 24 hours were characterized by beet red erythema, severe edema, and focal, superficial and second degree burns in all of the animals. Red, well-defined erythema, superficial escharosi
- Gross pathology:
- Necropsy examination revealed focal hemorrhages in the lungs of one female treated with 900 mg/kg and another treated with 3,038 mg/kg. Red lungs were found in one female treated with 1,350 mg/kg. Emaciation and depletion of body fat stores were observed in the two males treated with 3,038 mg/kg (one died).
Applicant's summary and conclusion
- Conclusions:
- The dermal LD50 is beyond 3,038 mg/kg. 2 -ethylhexylchloroformate is of low systemic toxicity via the dermal route.
- Executive summary:
The study is similar to a OECD 402 dermal toxicity study. Only 2 animals/sex and dose were used. However, the study is sufficient for end point evaluation (valid with restriction). 2 rabbits per sex were exposed to 600, 900, 1,350, 2,025 or 3,038 mg/kg 2 -ethylhexylchloroformate. The test material was severely irritating/corrosive to the skin. One male exposed to 3,038 mg/kg died at 12 days. There were no other deaths. The dermal LD50 is beyond 3,038 mg/kg. Focal hemorrhages in the lung, red lungs respectively point to an inhalative exposure towards 2-ethylhexylchloroformate.
Conclusion: The dermal LD50 is beyond 3,038 mg/kg. 2 -ethylhexylchloroformate is of low systemic toxicity via the dermal route.
