- Dose descriptor:
- LD50
- Effect level:
- 6 300 mg/kg bw
- 95% CL:
- 5 040 - 7 875
- Mortality:
- MORTALITY:
- Number of deaths at each dose:
5010 mg/kg bw: 3 males, 1 female dead within 14 days
6310 mg/kg bw: 4 males, 0 females dead within 5 days
7940 mg/kg bw: 4 males, 3 females dead within 7 days
LD50 = 6300 (5040-7875) mg/kg bw - Clinical signs:
- other: CLINICAL SIGNS: - 1 hour after treatment: piloerection, increased motility when touched - later: sedation, ataxia, staggering, squatting or abdominal position, tremor, hypothermia, loss of weight, halting motion, sanguineous orbital margins, blood
- Gross pathology:
- NECROPSY FINDINGS:
- animals that died during the study: hyperemia and (sometimes) swelling in the mucosa of stomach and small intestine (several animals); swelling
and discoloration of kidneys, hyperemia of peritoneum and mucosa of the bladder (sporadic)
- terminal necropsy: partial hyperemia of the small intestine mucosa (2 animals), swelling of the forestomach mucosa (5 animals), fusion of stomach and liver with peritoneum and diaphragm (1 animal) - Other findings:

Applicant's summary and conclusion
- Interpretation of results:
- not classified
- Remarks:
- Migrated information Criteria used for interpretation of results: other: EU Directive 67/548/EEC
- Conclusions:
- In a determination of the acute oral toxicity on male and female rats it was found that the LD50 of the test item 4-vinylcyclohexene is 6300 mg/kg of
body weight. Under the conditions of this study the acute toxicity of 4-vinylcyclohexene afer oral application in rats is very low. - Executive summary:
In a determination of the acute oral toxicity on male and female rats it was found that the LD50 of the test item 4-vinylcyclohexene is 6300 mg/kg of body weight. The treated animals showed signs of toxicity during the 14 day observation period. Body weight gain was transiently inhibited significantly. Animals that died during the study showed hyperemia and (sometimes) swelling in the mucosa of stomach and small intestine (several animals); swelling and discoloration of kidneys, hyperemia of peritoneum and mucosa of the bladder (sporadic). Dissection at the end of the experiment revealed partial hyperemia of the small intestine mucosa (2 animals), swelling of the forestomach mucosa (5 animals), fusion of stomach and liver with peritoneum and diaphragm (1 animal). Under the conditions of this study the acute toxicity of 4-vinylcyclohexene afer oral application in rats is very low.
