Materials and methods

Test guideline
Qualifier:
according to guideline
Guideline:
other: 16 CFR 1500.42
Deviations:
not specified
Principles of method if other than guideline:
The acute eye irritation test was determined on 9 young adult albino rabbits, selected from healthy, acclimated animals. The test material at the level of 0,1 ml or 0.1 g was applied to the right eye of each animal. The method employed was patterned after the procedure described in 16 CFR 1500.42.
The test procedure was modified as follows:
Group I: Six rabbits; eyes unwashed following the instillation of the test material.
Group II: Three rabbits; eyes washed 4 seconds following instillation of the test material.
All eyes were observed and ocular reaction recorded at 24,48, and 72 hours after instillation of the test material. They were observed again after 7 days.
GLP compliance:
no
