Clinical signs:
Diarrhea (from day 0 to day 4 with reducing number of animals)
Lethargy (from day 1 to day 2 in few animals)
Body oily (from day 2 to day 5 in all animals)
Chromorhinorrhea (from day 12 to day 14 in 1 to 2 male animals)
Body weight:

Gross pathology:
no data

Applicant's summary and conclusion

Interpretation of results:
not classified
Remarks:
Migrated information Criteria used for interpretation of results: EU
Conclusions:
In an acute oral toxicity test (only 1 dose, limit test), diisotridecyl adipate did not cause any mortality at a dose of 15000 mg/kg bw. Diisotridecyl adipate is not to be classified according to EU regulations.
Executive summary:

The acute oral toxicity of diisotridecyl adipate was determined in 5 male and 5 female Wistar rats each receiving 15 g/kg bw of the test material by oral gavage (limit test). The observation period was 14 days.

 

None of the animals died. Clinical signs (diarrhea, lethargy, oily bodies) were observed predominantly during day 0 to 5. Information on gross pathology is not reported.

 

The acute oral LD50 was determined to be > 15000 mg/kg bw in rats (Moreno/Mobil, 1978a).

 

This study is considered acceptable. It follows the principles of the retracted OECD test guideline 401 (Acute Oral Toxicity). Deviations are no determinatin of body weights and limited reporting.
