Materials and methods
Test guidelineopen allclose all
- Qualifier:
- according to guideline
- Guideline:
- other: Directive 67/548/EEC in the version of Directive 93/21/EEC
- Qualifier:
- equivalent or similar to guideline
- Guideline:
- OECD Guideline 404 (Acute Dermal Irritation / Corrosion)
- Version / remarks:
- 17 July 1992
- Deviations:
- yes
- Remarks:
- exposure time 24 hrs instead of 4 hrs, 6 animals instead of 3, few details in test description and reporting
- Principles of method if other than guideline:
- A combined study on acute dermal toxicity and on local tolerance was used to assess skin irritation/corrosion (comparable to OECD TG 402 and 404). The study design and reporting deviates from the current OECD TG 404, however, the study is considered sufficient for assessment of this endpoint. As described in ATP 96/54/EC ANNEX IV A, PART B: METHODS FOR THE DETERMINATION OF TOXICITY AND OTHER HEALTH EFFECTS, a strategy of testing for irritancy allows the non-performance of a test if an acute toxicity study by the dermal route has been conducted at the limit test dose with the substance (method B.3), and no skin irritation was observed, further testing for skin irritation (method B.4) may be unnecessary.
- GLP compliance:
- yes
- Remarks:
- - but a QA check was not performed

Applicant's summary and conclusion
- Conclusions:
- A single dermal administration of the test substance for 24 hours to male and female rats at a dose of 2000 mg/kg bw (210-222 mg/male and 186-214 mg/female applied as a paste) was tolerated without any local irritations. The mean values of findings relevant for classification (reddening, scab formation and swelling of the skin) during the observation period of 14 days were 0. Therefore, local application of the test item was tolerated without irritation of the skin.
- Executive summary:
In a primary dermal irritation study similar to OECD TG 404 (adopted 17 July 1992), (3/sex) female and male Wistar rats were dermally exposed to 186-214 mg females and 210-222 mg males of Epoxide-Valerate (100% a.i). in physiological saline. Test sites were covered with an occlusive dressing for 24 hours. Animals were then observed for 14 days. Evaluation of skin reactions (reddening, scab formation and swelling of the skin) was done according to the system recommended in Directive 67/548/EEC.
A single dermal administration of the test item for 24 h was tolerated without any local irritations. In this study, the test item is not a dermal irritant.
