ENVIRONMENTAL CONDITIONS
Air-conditioned with 10 - 15 air changes per hour and continuously monitored environment with target ranges for temperature of 20 ±3 °C and for relative humidity between 40 - 70 % (values above 70 % during cleaning process possible), 12 hours artificial fluorescent light (approx. 100 Lux) /12 hours dark, music during the light period - Type of coverage:
- semiocclusive
- Preparation of test site:
- clipped
- Vehicle:
- water
- Remarks:
- bi-distilled water
- Controls:
- yes, concurrent no treatment
- Amount / concentration applied:
- 0.5 g/animal (left side only)
- Duration of treatment / exposure:
- 4 hours
- Observation period:
- Viability/Mortality and Clinical Signs: Daily during the observation period.
Body Weights: At the start of acclimatization, on day 1 of test (application day) and at termination of observation.
The skin reaction was assessed at approximately 1, 24, 48 and 72 hours after the removal of the dressing, gauze patch and test article. - Number of animals:
- 1 male, 2 females
- Details on study design:
- Approximately 24 hours before treatment, the dorsal fur was clipped with an electric clipper, exposing an area of approximately 100 square centimeters (10 cm x 10 cm). The skin of the animals was examined once, 1 day prior to test article administration. Only those animals with no signs of skin injury or irritation were used in the test.
On test day 1, 0.5 g of the test article was applied to approx. 6 sq.cm of the intact skin of the clipped area. It was covered with a 3.0 cm x 3.0 cm patch of surgical gauze. The gauze was covered with a semi-occlusive dressing. The dressing was wrapped around the abdomen and anchored with an elastic bandage. The test article was applied in such a position as to preclude oral ingestion after removal of the dressing.
The duration of treatment was 4 hours. Then the dressing was removed and the skin was flushed with lukewarm tap water to clean the application site so that any reactions (erythema) were clearly visible at that time.
No necropsy was performed in the animals euthanized at termination of observation.
All rabbits were euthanized by an intravenous injection of NARCOREN (Rhone Merieux GmbH, D-88471 Laupheim) into the ear vein at a dose of at least 1.0 ml/kg body weight (equivalent to 160 mg sodium pentobarbitone/kg body weight) and discarded.

- Irritant / corrosive response data:
- CIBACRON GELB TZ 4210 ROH LÖSUNG (LABORGETROCKNET) (FAT 40'544/A) showed a primary irritation score of: 0.78, when applied to the conjunctival sac of the rabbit eye.
One (1) hour after instillation of the test article, moderate reddening and swelling of the conjunctivae were noted in all animals, as was moderate to marked watery discharge. Hyperemia of the scleral blood vessels was also evident in all animals.
Reddening and swelling of the conjunctivae tissues were reversible after 72 hours in two animals and after seven days in one animal. - Other effects:
- Light orange to orange-brown staining of the conjunctivae was noted in all animals until observation on day 14. From day 14 onwards, staining of the conjunctivae was yellow. Staining of the sclera was evident in all animals on day 21 after application. The corneas of all treated animals were unaffected.
No clinical signs of systemic toxicity were observed in the animals during the test and observation period, and no mortality occurred. No corrosion of the cornea was observed at any of the reading times. The body weight of the animals was within the normal range of variability. - Interpretation of results:
- GHS criteria not met
- Conclusions:
- The test substance is considered non-irritant to rabbit eyes.
- Executive summary:
The primary irritation potential of the test article was investigated according to method specified as per OECD test guideline 405 in a GLP certified laboratory.
0.1 g of test substance was instilled into conjuctival sac of each of three adult New Zealand rabbits. The treated eyes were not rinsed after application. Scoring of irritation effects was performed approximately 1, 24, 48 and 72 hours as well as 7, 14 and 21 days after test article application.
The scores of each animal at the following reading times (24, 48 and 72 hours) were used in calculating the respective mean values for each type of lesion.
The primary irritation score was calculated by averaging the individual cumulative scores at 24, 48 and 72 hours. Corneal opacity, iris and chemosis scores were zero at 24, 48 and 72h. Conjuctivae redness score was 0.78 which was reversible in 7 days.
Hyperemia of the scleral blood vessels was evident in all animals. No finding persisted longer than seven days. Light orange to orange-brown staining of the conjunctivae was noted in all animals until observation on day 14. From day 14 onwards, staining of the conjunctivae was yellow. Staining of the sclera was evident in all animals on day 21 after application. The corneas of all treated animals were unaffected.
No corrosion was observed at any of the measuring intervals. Thus, the substance is considered non-irritant to rabbit eyes.
