Test animals
- Species:
- rabbit
- Strain:
- New Zealand White
- Details on test animals or test system and environmental conditions:
- Animals were acclimatised to laboratory conditions for at least 5-days. The animals were housed individually in metal cages, identified by ear tattoo, kept at a constant room temperature of 20+3 °C, at a relative humidity of 30-70 % and on a 12 hours light cycle day. The rabbits received ad libitum standard rabbit pellet and fresh water. All batches of the diet are assayed for nutritive ingredients and contaminant level by the manufacturer.
The drinking water quality fulfilled the critical parameters in the specifications of the "Schweizerisches Lebensmittelbuch" (Edition 1972). The results of the routine chemical examination of water at source (Grundwasserfassung Stein) as conducted periodically by the water authority (Baudepartement des Kantons Aargau, Abteilung Gewaesserschütz ) are available to CIBA-GEIGY Limited, as well as the results of inhouse chemical analysis by
the analytical laboratories of the Pharmaceutical Division, CIBA-GEIGY Limited.
Test system
- Type of coverage:
- occlusive
- Preparation of test site:
- shaved
- Vehicle:
- unchanged (no vehicle)
- Controls:
- yes, concurrent no treatment
- Amount / concentration applied:
- 0.5 mL
- Duration of treatment / exposure:
- The patches were loosely covered with an aluminum foil (approx. 36 cm2) and held in place for 4 hours by an adhesive tape.
- Observation period:
- The animals were checked daily for systemic symptoms and mortality. The skin reactions were evaluated 1, 24, 48, and 72 hours after
removing the gauze patches according to the OECD scoring system - Number of animals:
- 3 male rabbits
- Details on study design:
- An area of at least 36 cm was shaved on both flanks of the animals approximately 24 hours before treatment. A gauze patch (approx. 12-16 cm2)
bearing 0.5 ml of the test material was applied to the right flank of each animal. A control gauze patch moistened with distilled water was applied to the contralateral flank.
The patches were loosely covered with aluminum foil (approx. 36 cm2) and held in place for 4 hours by an adhesive tape. The animals were checked daily for systemic symptoms and mortality.
The skin reactions were evaluated 1, 24, 48, and 72 hours after removing the gauze patches according to the OECD scoring system
The irritant/corrosive potency of TK 10406 was classified according to the EEC Council Directive 83/467

- Irritant / corrosive response data:
- The reactions were observed within 72 hours after removing the bandages, the observation period was extended to 14 days to determine
the reversibility of the skin reactions. According to the EEC classification of the results obtained 24 to 72 hours after removing the
bandages, the test material must be classified as irritant in albino rabbits.
The erythema and edema reactions observed were reversible until the end of the observation period on day 14.
In one animal the treated skin showed a yellowish discoloration 72 hours after patch removal, and on experimental day 7 a white crust was formed
within a small area of the exposed skin. Scaling was observed in this animal from day 7 until the final reading on day 14, and in another animal on
days 7 and 10 of the test.
Applicant's summary and conclusion
- Interpretation of results:
- Category 2 (irritant) based on GHS criteria
- Remarks:
- Migrated information
- Executive summary:
An acute Dermal Irritation/Corrosion Study in the Rabbit was conducted in accordance with the OECD 404 test guideline. An area of at least 36 cm was shaved on both flanks of the animals (3 males) approximately 24 hours before treatment. A gauze patch (approx. 12-16 cm2) bearing 0.5 ml of the test material was applied to the right flank of each animal. A control gauze patch moistened with distilled water was applied to the contralateral flank. The patches were loosely covered with aluminum foil (approx. 36 cm2) and held in place for 4 hours by an adhesive tape. The animals were checked daily for systemic symptoms and mortality.
The skin reactions were evaluated 1, 24, 48, and 72 hours after removing the gauze patches according to the OECD scoring system and the irritant/corrosive potency of the test material was classified according to the EEC Council Directive 83/467. The reactions were observed within 72 hours after removing the bandages, the observation period was extended to 14 days to determine the reversibility of the skin reactions. According to the EEC classification of the results obtained 24 to 72 hours after removing the bandages, the test material must be classified as irritant in albino rabbits. After 72 -hours, the mean irritation parameters for erythema and edema were 2.11 and 1.0 respectively. Because the mean values of the readings 24 to 72 hours after application are above the threshold of significance (score 2 for erythema or edema) the substance must be classified as irritant according to the EEC Council Directive 83/467. The erythema and edema reactions observed were reversible until the end of the observation period on day 14.
