Applicant's summary and conclusion

Interpretation of results:

Toxicity Category III

Remarks:

Migrated information Criteria used for interpretation of results: EU

Conclusions:

The substance was acutely toxic to rats after a single oral exposure. Due to the observed LD50 of 218 mg/kg bw the substance is to be classified into Acute Toxicity Hazard Category 3 according to the CLP regulation (second amendment of March 2011).

Executive summary:

The acute oral toxicity of the test substance allyl caproate (allyl hexanoate) was studied in a pre-GLP, pre-guideline study which to a great extent followed the standard acute method described in OECD TG 401. Groups of 10 rats of the Osborne-Mendel strain evenly distributed between the sexes received single oral doses of the test substance by oral gavage. The animals were then observed for signs of toxicity during a period of 14 days. Non-mortal clinical effects including depression and scrawny appearance were observed. In this study, mortality of exposed animals was observed between 4 and 18 hours after a single oral exposure. The LD50 value calculated by the method of Litchfield and Wilcoxon (1949) was 218 mg/kg bw with a 95% confidence level ranging from 186 to 255 mg/kg bw. This LD50 value triggers classification according to CLP (second amendment of March 2011) into Acute Toxicity Hazard Category 3.
