Applicant's summary and conclusion
- Conclusions:
- The acute dermal toxicity of the test substance in Vienna white rabbits was determined. The product was applied as a 50% aqueous test substance preparation by single dose of 200 mg/kg for 24 hours on clipped areas (about 50 cm2) of the back and flanks. The determination of the LD50 was based on the DOT guidelines, but no exact LD50 was established.
