Age: about 27 weeks
Initial Weight: 3.66 kg (3.15-4.25 kg)
Identification and adaptation
The animal was kept in the experimental room for more than 7 days to allow them to acclimatize. The animal was uniquely identified by a tattoo in the ear displaying the animal number. An individual cage card was affixed to the cage displaying the study number, test material, day of treatment, and animal number.
Housing and diet
The rabbits were housed in an air-conditioned room of about 28 m^2 in the Institute of Toxicology. Lighting was controlled by a timer to provide a 12-hour light and a 12-hour dark regime. They were kept separately in special rabbit cages (manufacturer: Becker; type K99/30 KU, floor area about 5400 cm^2, a shelter with an integrated sitting board of about 1820 cm^2; overall height: 60 cm) with plastic grids placed on mobile racks. The collection pans underneath the cages were cleaned at least three times a week. The cages were cleaned before the start of the study. Temperature and relative humidity were measured using a thermohygrograph. The room temperature varied from 20 to 21 °C and the relative humidity from 59 to 68 %. The rabbits received a commercial diet for rabbits, Altromin Standard Diet ad libitum and fresh tap water from Makrolon drinking bottles ad libitum. According to the specifications given by the manufacturer, the diet had been checked by independent laboratories. Analysis included both qualitative and quantitative evaluation for heavy metals, aflatoxins, pesticides, and antibiotics. The drinking water was periodically analyzed according to the German regulations for human drinking water. - Type of coverage:

- Executive summary:
The purpose of this assay was to identify the skin irritation/corrosion potential of the test material when applied to the intact skin of previously shaven rabbits for a 4 hours period under semiocclusive conditions.
This study should provide a rational basis for risk assessment to the irritating potential of the test item in man and was conducted according to OECD 404.
To test for primary skin irritation, 0.5 g of the test material was mixed with some drops of aqua pro injectione to ensure good contact with the skin. Afterwards the test material was spread onto 6 cm2 patches and applied to the intact skin of three previously shaven rabbits for a 4 hours period under semiocclusive conditions.
The first examination of the treated skin sites followed 1 hour after removal of the patches. Thereafter, examinations were performed daily for another 7 days.
No signs of irritation were observed after administration. Thus, the test item is considered to possess no skin irritating properties.

Age: about 31-32 weeks
Mean weight: 4.3 kg
- Identification and adaptation: Healthy rabbits were allocated to the study group. The animals were kept in the experimental room for more than 7 days to allow for acclimatization. Each animal was uniquely identified by a tattoo in the ear displaying the animal number. Individual cage cards were affixed to each cage displaying the study number, test material, day of treatment, and animal number.
- Housing and diet: All rabbits were housed in an air-conditioned room of about 28 m^2 in the test facility. Lighting was controlled by a timer to provide a 12-hour light and a 12-hour dark regime. They were kept separately in special rabbit cages (manufacturer: Becker; type K99/30 KU, floor area about 5400 cm^2, a shelter with an integrated sitting board of about 1820 cm^2; overall height: 60 cm) with plastic grids placed on mobile racks. The collection pans underneath the cages were cleaned at least three times a week. The cages were cleaned before the start of the study. Temperature and relative humidity were measured using a thermohygrograph. The room temperature varied from 20 to 22 °C and the relative humidity from 50 to 64 %. The rabbits received diet for rabbits Provimi Kliba 3418.0 and sniff K snack ad libitum, and fresh tap water from Makrolon drinking bottles at least three times a week. The diet is checked periodically according to the specifications of the manufacturer by an independent laboratory, approved by the German government. Analysis includes both qualitative and quantitative evaluation for heavy metals, aflatoxins, pesticides, and antibiotics. The drinking water is periodically analyzed according to the German regulations for human drinking water. - Vehicle:
- unchanged (no vehicle)
- Controls:
- yes, concurrent no treatment
- Amount / concentration applied:
- 0.1 g
- Observation period (in vivo):
- 1 hour after treatment, after 24, 48, and 72 hours, then daily up to day 8 of the experimental part.
- Number of animals or in vitro replicates:
- 3 female rabbits
- Details on study design:
- - Preparation: Before the application, the test material was ground in a mortar using a pestle.
- Administration and dose level: To ensure that only rabbits with normal eyes were included in the study, approximately 24 hours before treatment ophthalmological examinations were performed after instillation of a 0.15 % fluorescein solution (Dr. Thilo & Co.) using an ophthalmoscope. Animals with eye defects, injury or irritation were excluded. 0.1 g test material was instilled into the conjunctival sac of the left eye of each animal by gently pulling the lower lid away from the eyeball to form a cup into which the test material was placed. The right eye remained untreated and served as control. After instillation, the eyelids were closed for about 30 seconds.
- Observation for clinical symptoms: The rabbits were examined for eye irritation and for changes in behavior and general condition 1 hour after treatment, after 24, 48, and 72 hours, then daily up to day 8 of the experimental part. Eye changes were evaluated according to the DRAIZE- , OECD- and EEC recommendations.

To test for eye irritation a test according to the OECD-Guidelines for Testing of Chemicals No. 405, the annex to Directive 92/69 EEC, and the recommendations of DRAIZE (1959) was performed.
All animals survived the observation period. Body weight development of the treated rabbits was inconspicuous. No signs of clinical toxicity were detected. No signs of irritation were observed at the cornea or iris. All animals showed discharge (score 1) one hour after instillation of the test material. Furthermore, a yellowish discoloration of the hairs around the eyes was seen in all treated animals up to day 6 and 7 of the experimental part. No abnormalities were detected in the untreated eyes.
No eye irritating potential of the test item could be detected, thus the test material should not be classified as eye irritant according to EU Regulation No. 1272/2008 (CLP).
