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.
