- Conclusions:
- According to the test results, the dermal LC50 for NPE-4 was determined to be greater than 2,000 mg/kg bw.
- Executive summary:
A study was conducted to evaluate the acute dermal toxicity of a commercial formulation of NPE-4 to rabbit. Under the study conditions, the dermal LD50 was > 2,000 mg/kg bw (Talmage SS, 1994).
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
