Results and discussion
Effect levels
- Sex:
- male/female
- Dose descriptor:
- LD50
- Effect level:
- > 16 mL/kg bw

Applicant's summary and conclusion
- Interpretation of results:
- practically nontoxic
- Remarks:
- Migrated information
- Conclusions:
- The acute dermal LD50 for rabbits was >16.0 ml/kg.
- Executive summary:
Two groups of rats (five males and five females/group) were dermally exposed toVinyl 2 -ethylhexanoate (16.0 and 8.0 ml/kg per group) under occlusion for 24 hr. The obsrvation period was 14 days. The application of vinyl 2 -ethylhexanoate at doses of 16.0 and 8.0 ml/kg to skin of rat for 24 hr produced an LD50 of >16.0 ml/kg.
