168 hour(s)
Observation period (in vivo):
7 days
Number of animals or in vitro replicates:
6
Details on study design:
- Comment: not rinsed
- In general, the techniques of tests as published by the FDA of the United States (Fed. Reg. 28 (119): 5582, 1963) and Draize and Kelley (Drug Cosmet. Industr. 71: 36, 1952) were followed.
- Pretest: The eyes of the animals were examined before testing and only those animals without observable eye defects are used.
- Total dose: 0.1 mL of the undiluted test material
- Instillation procedure: 0.1 mL of the undiluted test substance was allowed to fall on the everted lower lid of one eye of each rabbit; the upper and lower eye lid were then carefully closed and subsequently held together for at least one second before releasing, to prevent loss of material. The other eye remaining untreated, served as a control. The eyes were not washed following instillation.
- Readings of eye reactions: The eyes were examined at one hour, 24, 48, 72 hours and 7 days after instillation of the test material.
- Evaluation of eye reactions: Eye reactions were evaluated by the method published by Draize and Kelley (1952). Drug. Cosmet. Industr. 71: 36

The test compound caused slight lesions of the conjunctivae in all  rabbits. After 24 hours these lesions had subsided completely.

After 48, 72 hours and 7 days all scores were recorded as 0.
-------------------------------------------------------------------------- ------------------

Mean values over 24, 48, and 72 hours for the single animals for cornea,  iris and conjunctivae were without exception zero.  
Thus, the eye irritation score was calculated to be zero.
