Administration / exposure
- Type of coverage:
- occlusive
- Vehicle:
- physiological saline
- Details on dermal exposure:
- Preparation of the test substance
0.5 g Reaktiv-Gelb F-68 072 FW was moistened with 0.25 ml isotonic saline.
Test procedure
Before dermal treatment the fur was mechanically removed from the dorsal skin of the animals over an area of approximatly 30 cm2.
The appropriate amount of the test substance was moistened on an aluminium foil (6x8 cm) and distributed as uniformly as possible. Together with the foil the test substance was applied to the shaved and intact dorsal skin. The foil was held in place with an elastic plaster bandage fixed around the animal's body (Fixomull, and Elastoplast®, 8 cm in width, both manufactured by Beiersdorf).
At the end of the dermal exposure period of 24 hours the bandage was removed and the treated skin area washed with warm water in order to remove any unabsarbed remnants of the test substance. - Duration of exposure:
- 24 h
- Doses:
- 2000 mg/kg body weight
- No. of animals per sex per dose:
- 5 males, 5 females
- Control animals:
- no
- Details on study design:
- The observation period after the dermal application lasted for 14 days. Symptoms were recorded twice every day (in the morning and in the afternoon), on weekends and holidays only once. During this time the animals were weighed weekly. At the end of the observation period the animals were killed by carbon dioxide asphyxiation, dissected and examined for macroscopically visible changes.

Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- Acute dermal toxicity testing of Reaktiv-Gelb F-68 072 FW in the Wistar rat yielded a median lethal dose above 2000 mg/kg b,w. in both male and female animals.
- Executive summary:
The present study was conducted in compliance with OECD Guidelines for Testing of Chemicals, 402 "Acute Dermal Toxicity",andEEC Guideline B.3, Acute Dermal Toxicityin Council Directive 84/449/EEC.This study was conducted in compliance with the Principles of Good Laboratory Practice(GLP).
Acute dermal toxicity testing of Reaktiv-Gelb F-68 072 FW in the Wistar rat yielded a median lethal dose above 2000 mg/kg b,w. in both male and female animals.
Beside unspecific symptoms the animals showed impairments of respiration and motility as well as diarrhea. Additionally clonic convulsions, trembling, straub tail, straddling hind limbs and hypersensitivity to touch were observed in females. Four days p.a. the animals were free of clinical symptoms.
The skin of the animals showed encrustations and coarse scales. Additionally the skin of all animals was discoloured orange during the whole study.
Body weight development of the animals was not impaired.
The animals killed at the end of the observation period showed no macroscopically visible changes.
