-EEC Directive B.4. 'Acute toxicity Skin Irritation' of the Directive 84/449/EEC: Commission Directive of 25 April 1984 adapting to technical progress for the sixth time Council Directive 67/548/EEC on the approximation of the laws, regulations and administrative provisions relating to the classification, packaging and labelling of dangerous substances
-OECD Guidelines for Testing of Chemicals, 404 "Acute Dermal Irritation/Corrosion", OECD 1981
Updated guideline, adopted: 17th July 1992
-The study was conducted in compliance with the Principles of Good Laboratory Practice Annex of paragraph 19a, section 1 of the chemical law from August 1990
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 lndanthren-Oliv HT Colloisol pasted with 0.3 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 Beiersdorf AG, Hamburg).

Examinations of the skin took place after 30 - 60 minutes, and 24, 48 and 72 hours after removal of the patches.
From 30 minutes up to 24 hours after removal of the patches the treated skin ofall animals showed very slight up to moderately strong erythema as well as up to 48 hours p.a. a barely perceptible erythema in one animal.
72 hours after removal of the patches the irritations were reversible.
Based on the results of this study lndanthren-Oliv HT Colloisol is slightly irritating to skin.

- Details on study design:
- About 24 hours before the start of the study the test eyes of all animals were examined under UV light for corneal lesions after instillation of one drop of a 0.01 % fluorescein-sodium solution. Only animals without ocular abnormalities were used for the study.100 mg lndanthren-Oliv HT Colloisol was applied once to the conjunctival sac of the left eye of 3 rabbits. The untreated eyes served in each case as a control.24 hours after application and at all other designated examination times at which the treated eyes still showed discharge or at which a corneal examination with fluorescein-sodium solution took place, the treated eyes were washed out thoroughly with physiological saline at approx. 37 °C.The eyes were examined 1, 24, 48 and 72 hours after application of the test substance. At 24 and 72 hours the eyes were also examined for corneal lesions under UV light after instillation of one drop of 0.01 %fluorescein-sodium solution. Lesions in cornea, iris or conjunctivae were graded numerically. All other changes or toxic effects were recorded.

Additional information
In the key in vivo skin irritation study, 0.5 g of the test material (containing 46.2% of the test substance) was applied to the intact, shaved skin of each of 3 New Zealand, albino rats. The substance was applied over the whole surface of a 2.5 x 2.5 cm cellulose patch on a piece of surgical plaster; the plaster was fixed to the prepared skin area and then covered with a semi-occlusive bandage. From 30 minutes up to 24 hours after removal of the patches the treated skin of all animals showed very slight up to moderately strong erythema as well as up to 48 hours p.a. a barely perceptible erythema in one animal. The erythema was reversible in all animals within 72 hours. It was concluded that the test substance is slightly irritating to the skin, however, the results of this study do not trigger classification of the test substance as a skin irritant in accordance with the CLP Regulation.
There are also four supporting in vivo skin irritation studies available:
In the first study, 0.5 ml of the test material (containing ca. 40% of the substance) was applied to intact and abraded, shaved skin of each of 6 New Zealand, albino rats. Extremely superficial second degree chemical burns were noted at the 24-hour scoring interval on all sites (the erythema was not reversible after 72 hours at all sites). The burns were considered too superficial to be given a maximum score of four for both erythema and oedema. For all the intact skin sites, the mean erythema score was 2.8 after 72 hours.
In the second study, the test material (containing 43.5% of the substance) was applied to the intact and abraded, shaved skin of each of 6 rabbits of the Russian breed. The primary irritation index was 0.1 indicating that the substance is a mild irritant to the rabbit skin.
In the third study, the test material (containing 43.5% of the substance) was applied to the intact and abraded, shaved skin of each of 6 rabbits of the Russian breed. Under the conditions of the experiment the test preparation was found to cause no irritation when applied to intact skin and to abraded rabbit skin.
In the fourth study, the test material (containing 43.5% of the substance) was applied to the intact and abraded, shaved skin of each of 6 rabbits of the Russian breed. Under the conditions of the experiment the test preparation was found to cause no irritation when applied to intact skin and slight irritation when applied to abraded rabbit skin.
In the key in vivo eye irritation study, 100 mg of the test substance (containing 46.2% of the test substance) was applied to the left eye of each of 3 New Zealand Albino rabbits. The treated eyes were washed 24 hours after application. Redness of the conjunctiva was observed 1 hour after the application, reversible after 48 hours (mean score of 0.2). Therefore, these results do not trigger classification of the test substance as an eye irritant in accordance with the CLP Regulation.
There are also four supporting in vivo eye irritation studies available:
In the first study, 0.1 ml of the test material (containing ca. 40% of the substance) was applied to the right eye of each of 6 young, albino rabbits of the New Zealand strain. The test material was practically non-irritating.
In the second study, 0.1 ml of the test material (containing 43.5% of the substance) was applied to the right eye of each of 6 rabbits of the Russian breed. In 3 rabbits, approximately 30 seconds after administration, the treated eyes were flushed with water. The primary irritation index, a measure of the acute eye irritation provoked by the substance, was 0 for the cornea, 0 for the iris and 0 for the conjunctivae. This indicates that the substance is not an irritant to the rabbit eye.
In the third study, 0.1 ml of the test material (containing 43.5% of the substance) was applied to the right eye of each of 6 rabbits of the Russian breed. In 3 rabbits, approximately 30 seconds after administration, the treated eyes were flushed with water. Under the conditions of the experiment that test preparation was found to cause practically no irritation when applied to the rabbit eye mucosa.
In the fourth study, 0.1 ml of the test material (containing 43.5% of the substance) was applied to the right eye of each of 6 rabbits of the Russian breed. In 3 rabbits, approximately 30 seconds after administration, the treated eyes were flushed with water. Under the conditions of the experiment that test preparation was found to cause practically no irritation when applied to the rabbit eye mucosa.
Justification for classification or non-classification
The test substance is not classified as either a skin irritant or as an eye irritant in accordance with the CLP Regulation.
