Applicant's summary and conclusion

Interpretation of results:
sligthly toxic
Remarks:
Migrated information
Conclusions:
No mortality were observed in any of the two doses tested. The acute LD50 value is therefore above 5000 mg/kg
Executive summary:

The acute toxicity of phenoxyethyl acrylate was tested in a single dose acute toxicity test, comparable to OECD Guideline 401. Two doses were tested 2150 and 5000 mg/kg. The substance was giving orally dissolved in olive oil, total volume was 5 and 10 ml/kg bw, which is acceptable according to the OECD guideline. Several clinical signs were observed, such as dyspnoea, shaggering, shaggy fur, redness of skin and hemi paralysis. The symptoms gradually ceased within hours to two days, except shaggy fur in the highest dose. No mortality was observed at any of the doses, therefore the acute LD50 value is above 5000 mg/kg.
