Applicant's summary and conclusion

Interpretation of results:
not classified
Remarks:
Migrated information Criteria used for interpretation of results: EU
Conclusions:
The dermal LD50 for rabbits was greater than 2.0 g/kg. According to Regulation (EC) No. 1272/2008, no classification is warranted, based on the absence of signs of toxicology and mortalities in a group of four rabbits.
Executive summary:

In a study conducted by Moreno (1973), the dermal LD50value was derived for amyl cinnamic aldehyde in a group of four rabbits.

The dermal LD50 for rabbits was greater than 2000 mg/kg bw. According to Regulation (EC) No. 1272/2008, no classification is warranted.
