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.
