Administration / exposure
- Type of coverage:
- semiocclusive
- Vehicle:
- unchanged (no vehicle)
- Details on dermal exposure:
- A single dermal application of the test article was performed. The substance was held in contact with the skin with a porous gauze dressing and Elastoplast (Beiersdorf). The exposure period was 24 h. The test article was applied undiluted in a volume of 2.15 ml/kg.
- Duration of exposure:
- 24 h
- Doses:
- 2000 mg/kg bw
- No. of animals per sex per dose:
- 5
- Control animals:
- no
- Details on study design:
- In each animal a number of clinical-toxicological signs were evaluated according to a modified Irwin-Screening procedure (Screening Methods in Pharmacology, R. A. Turner, 1965, p. 26). The animals were examined at the following post-treatment intervals: 10 min, 1 h, 2 h, 6 h, 24 h, and thereafter once daily up to day 14.

- relatively harmless
- Remarks:
- Migrated information Criteria used for interpretation of results: EU
- Conclusions:
- Substance has a dermal LD 50 of > 2000 mg/kg bw
- Executive summary:
An acute dermal toxicity study of isopropenyl acetate (99.5% pure) was conducted in the Wistar Hsd/Cpb:Wu rat in accordance with OECD Guideline 402 which yielded a dermal LD50 of > 2000 mg/kg body weight. Single 24 h semi-occlusive application of 2000 mg isopropenyl acetate/kg bw to the depilated dorsal skin of 5 males and 5 females was tolerated without remarkable findings. During the subsequent 14 days observation period, no animal dies, no skin changes or clinical signs were observed and body weight gain was normal. Terminal necropsy was without abnormal findings.
