Materials and methods
Test guideline
- 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

Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- 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 (556-564 mg/male and 408 -414 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) at the time-points 24, 48 and 72 hours after the end of administration were 0. Therefore, local application of ZK 47525 (fluocortolone-A-acetate) was tolerated without irritation of the skin.
- Executive summary:
In a primary dermal irritation study equivalent to OECD test guideline 404, young adult Wistar rats (3/sex) were dermally exposed to 556 and 564 mg + 0.6 mL vehicle, 556 mg + 0.5 mL vehicle, 408-414mg + 0.5 mL vehicle of Fluocortolone acetate (100% a.i.) in liquid paraffin for 24. Animals then were observed for 14 days. Irritation was done according to the system recommended in Directive 67/548/EEC.
A single dermal administration of the test substance for 24 hours to male and female rats at a dose of 2000 mg/kg bw (556-564 mg/male and 408 -414 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) at the time-points 24, 48 and 72 hours after the end of administration were 0.
