Test animals
- Species:
- rat
- Strain:
- not specified
- Sex:
- male
- Details on test animals or test system and environmental conditions:
- TEST ANIMALS
- Weight at study initiation: the body weight ranged from 206 to 246 g
- Fasting period before study: 18 hours
Administration / exposure
- Route of administration:
- oral: gavage
- Vehicle:
- unchanged (no vehicle)
- No. of animals per sex per dose:
- 6 male albino rats
- Control animals:
- no
- Details on study design:

Results and discussion
Effect levels
- Key result
- Sex:
- male
- Dose descriptor:
- LD50
- Effect level:
- > 5 000 mg/kg bw
- Based on:
- test mat.
- Mortality:
- One rat died on the fourth day.
- Clinical signs:
- other:
- Gross pathology:
- Hemorrhagic lungs. solid mass in stomach, not adhered to stomach wall but too large to pass through pyloric valve. Cardic portion of stomach distended. Food in intestines as in a normal rat. One rat had dilated intestinal blood vessels.
Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- The oral LD50 of ethyl-2-cyanoacrylate is estimated to be higher than 5000 mg/kg body weight in rats for a single dose.
Therefore the test substance ethyl-2-cyanoacrylate can be considered practically nontoxic according to the EC Guideline 93/21.
