Applicant's summary and conclusion

Interpretation of results:
practically nontoxic
Criteria used for interpretation of results: EU
Based on the absence of mortality and lack of adverse treatment-related clinical toxicity, the acute oral LD50 of 1-dodecene, dimer hydrogenated is considered to be >5000 mg/kg bw in the rat.
Executive summary:

In an acute oral toxicity study (Driscoll, R., 1995; Klimisch score = 1), 5000 mg/kg bw of 1 -dodecene dimer, hydogenated was orally administered via gavage to Sprague-Dawley rats (5/sex). The animals were observed over a period of 14 days for mortality and signs of clinical toxicity.

No mortality was observed in male or female rats during the study. The test animals did not exhibit any signs of adverse clinical toxicity. Body weights remained unaffected through the test period and gross necroscopy at termination did not reveal any remarkable findings.

Based on the absence of test material related mortality and lack of adverse signs of clinical toxicity, the acute oral LD50 for 1 -dodecene dimer, hydrogenated is considered to be >5000 mg/kg body weight in the rat.
