- yes, concurrent no treatment
- Amount / concentration applied:
- 500 mg
- Duration of treatment / exposure:

- Observation period:
- 72 hours
- Number of animals:
- 3
- Details on study design:
- About 24 hours before the start of the study the hair in the dorsal region of the body of 3 rabbits was removed with an electric clipper over an area of about 25 cm2. Only animals with intact skin were used.
Each animal was treated with 0.5 g Reaktiv-Gelb F-68 072 FW pasted with 0.25 ml isotonic saline. The substance was applied over the whole surface of a 2.5 x 2.5 cm cellulose patch on a piece of surgical plaster (specially produced by Beiers-dorf AG, Hamburg). The plaster was fixed to the prepared skin area and then covered with a semi-occlusive bandage.
The exposure period was 4 hours. After the exposure period all remnants of the test substance were carefully removed from the skin with warm tap water.
Examinations of the skin took place after 30 - 60 minutes, and 24, 48 and 72 hours after removal of the patches.
Erythema, eschar formation and oedema were evaluated numerically according to the technique of DRAIZE.

Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- Based on the results of this study Reaktiv-Gelb F-68 072 FW is not irritating to skin.
- Executive summary:
Testing for primary dermal irritation provides information on the irritant effect of the test substance on the skin following a single dermal application and serves as a basis for classification and labelling.
The present study was conducted in compliance within EEC Directive B.4. 'Acute toxicity Skin Irritation' of the Directive 84/449/EEC and OECD Guidelines for Testing of Chemicals, 404 "Acute Dermal Irritation/Corrosion". This study was conducted in compliance with the Principles of Good Laboratory Practice(GLP).
Testing of Reaktiv-GelbF-68 072FW for primary dermal irritation in the rabbit showed, that the substance is not irritating to skin.
30 - 60 minutes after removal of the patches all animals showed very slight erythema and two animals very slight oedema. One day after removal of the patches two animals showed a very slight or a well defined erythema. Two days after removal of the patches a very slight erythema was observed in one animal. Three day after removal of the patches all irritations were reversible.
Based on the results of this study Reaktiv-GelbF-68072FW is not irritating to skin.
