Dermal absorption
Administrative data
- Endpoint:
- dermal absorption in vivo
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Reliability:
- 2 (reliable with restrictions)

- ethanedinitrile 99.5%
- Radiolabelling:
- no
Test animals
- Species:
- rabbit
- Strain:
- not specified
- Sex:
- male
Administration / exposure
- Type of coverage:
- open
- Vehicle:
- other: air
- Duration of exposure:
- 8h
- Doses:
- 10,000 ppm
- No. of animals per group:
- 4
- Control animals:
- yes
- Details on study design:
- 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.
Results and discussion
- Signs and symptoms of toxicity:
- no effects
- Dermal irritation:
- no effects
Applicant's summary and conclusion
- Conclusions:
- No dermal absorption was observed after exposure of rabbit to 10,000 ppm of ethanedinitrile.
- Executive summary:
