- Four male albino rabbits whose weights averaged 4.5 pounds were closely clipped of their fur, restrained in a wooden stock, and placed in the chamber. An especially designed door, through which the rabbits heads extended into glass jarsmaintained under positive air pressure, prevented the rabbits from breathing cyanogen while their bodies were being exposed and also made observation of the heads of the rabbits possible. The bodies of the rabbits were exposed to ethanedinitrile concentration of 10,000 ppm for a period of 8 hours.

Applicant's summary and conclusion
- Interpretation of results:
- other: CLP criteria not met
- Conclusions:
- Dermal exposure of rabbits to ethanedinitrile gas in an acute toxicity study indicates that there is no intake of ethanedinitrile through skin. Dermal exposure of rabbits to 10,000 ppm (~21 g/m3) of ethanedinitrile for eight hours did not result in toxicity towards rabbits, or any clinical observations or macroscopic effects.
- Executive summary:
