- Details on test animals or tissues and environmental conditions:
- TEST system hen eggs
- Type of eggs/strain/quality: Fresh, fertilized hen eggs produced under controlled SPF conditions. White Leghorn, SPAFAS Inc., USA, SPF Premium
- Source: Charles River Deutschland GmbH, Extertal
- Weight range at start of incubation period: 50.8 g – 53.6 g
INCUBATION:
Breeding in an incubator at constant temperature of 37.5°C (± 0.5°C) and a relative humidity of 62.5% (± 7.5%). Until including incubation day 8 and/or day 9, the eggs were rotated automatically 6 times a day. On the day before application the eggs were placed with the blunt end upward and were not rotated until preparation. The eggs were candled before the start of incubation and on the 9th and/or 10th day. Any defective or unfertilized eggs were discarded.
Test system

- EXPERIMENTAL PROCEDURE
- Route of application: After careful removal of the eggshell including the inner membrane directly onto the chorionallantoic membrane.
- Application procedure: A bulk volume of 25 μL (about 19 mg) per egg of the ground solid test substance was applied on approximately the half of the membrane area, starting from the center. The visible parts of the membrane were observed. The test substance was removed by washing with 0.9% aqueous NaCl-solution after 100 seconds. A final assessment of the CAM was performed immediately after washing.
- Preparation and opening of the eggs: The eggs were candled on the day of application to ensure viability and in order to mark the location of the air chamber with a felt pen. The eggshell was cut along the marking line with an electric drill and removed exposing the egg membrane, which forms the inner barrier between egg content and air chamber. This membrane was moistened with warm physiological saline and the eggs were then placed in the incubator again until they were used for testing (maximum of 30 minutes between opening the eggs and application).
- Selection of the eggs: After removal of the egg membrane the CAM was investigated for signs of pre-existing damage, which would exclude the egg from the assay. Only eggs with an adequate vascular system and even CAM surface were used for the study.
- Assessment of reactions: After application of the test substance the chorionallantoic membrane was observed by means of a stereomicroscope until unambiguous irritation reactions were detected or up to a maximum time period of 100 seconds, respectively. The time of appearance (in seconds after application) of intravascular resp. extravascular coagulation, and if applicable other reactions (haemorrhagia, vessel lysis), were determined. The evaluation of the reactions was performed according to the following grading: 0 No visible change, 1 Slight reaction, 2 Moderate reaction, 3 Severe reaction.
- Positive controls: On each study day, before and/or after application of test substances, positive control substances (aqueous solution of 0.1 M NaOH and 10% SDS (Sodium dodecyl sulfate)), which are known to cause moderate to severe irritation were tested, in order to demonstrate the sensitivity of the method.
EVALUATION OF RESULTS
- The evaluation depends on the solubility of the test substance, the tested concentrations and the time until appearance of unambiguous intravascular coagulation of middle-sized vessels or extravascular coagulation of the treated CAM, respectively. The mean time until appearance of reaction over the eggs of a treatment group was calculated (mean time to coagulation = mtc in seconds).

Applicant's summary and conclusion
- Interpretation of results:
- other: does not produce serious eye damage
- Conclusions:
- Under the conditions of the test the substance is considered to be of no rlsk of serious damage to the eyes.
- Executive summary:
In a GLP-compliant study, the potential of the test substance to cause serious damage to the eyes/mucous membranes was assessed by a single topical application of 25μL bulk volume (about 19 mg) of the undiluted test substance to the chorionallantoic membrane (CAM) of fertilized and incubated hen eggs. Three eggs were observed for 100 seconds and then the test substance was removed by washing. The occurrence of vascular injury or intravascular coagulation in response to the test substance was recorded. The chorionallantoic membrane of the eggs did not show any irritation effects. Based on the results of this study it is concluded, that the test substance does not produce changes indicative for serious eye damage in the HET-CAM Test under the test conditions chosen.
