- Amount / concentration applied:
- TEST MATERIAL
- Amount(s) applied (volume or weight with unit): 0.1 mL - Duration of treatment / exposure:
- Single treatment without washing
- Observation period (in vivo):
- 72 h
- Number of animals or in vitro replicates:
- 3 per sex
- Details on study design:
- SCORING SYSTEM: Draize scoring system
TOOL USED TO ASSESS SCORE: hand-held penlight / fluorescein
MORTALITY:
The rabbits were observed twice daily (morning and afternoon) for mortality for the duration of the study.
OCULAR OBSERVATIONS:
Both eyes of each rabbit were examined for ocular abnormalities prior to initiation of dosing. The pre-initiation examination included the use of sodium fluorescein and ultraviolet light for detection of corneal abnormalities. The rabbits assigned to study had no pre-existing ocular abnormalities. Both eyes of each rabbit were examined macroscopically for ocular irritation using a handheld penlight in accordance with the method of Draize at approximately one, 24,48 and 72 hours after dosing. In addition, both eyes were further examined at 72 hours with sodium fluorescein and ultraviolet light.
BODY WEIGHTS:
The body weights were obtained and recorded on study day 0 (initiation) and on day 3 (termination).

- Irritant / corrosive response data:
- After 1 h redness and chemosis (grade 1) were observed in 5/6 and 4/6 animals, respectively. These effects were reversible within 24 h. At 48 h one animal had a redness score of 1, which again was fully reversible upon the next reading time point (72 h). No effects on cornea and iris were observed in any anmal at any time point.
- Other effects:
- There were no deaths during the study. The rabbits did not vocalize upon instillation of the test material. There were no remarkable changes or differences observed in body weight during the study period.
