REMOVAL OF TEST SUBSTANCE: Not applicable

SCORING SYSTEM: initial pain reaction from 6-point scale, Draize scale for scoring ocular irritation was used during the observation period. After scores were assigned, a modified version of Kay and Calandra (1962) was used to classify the ocular irritancy potential.

TOOL USED TO ASSESS SCORE: ophthalmoscope

Applicant's summary and conclusion

Interpretation of results:

slightly irritating

Remarks:

Migrated information Criteria used for interpretation of results: other: modified Kay and Calandra 1962

Conclusions:

The test substance was determined to be a mild irritant (Class 4 on a 1 - 8 scale) to the rabbit eye according to a modified Kay and Calandra classification system.

Executive summary:

Introduction. The study was performed to assess the irritancy potential of the test material to the eye of the New Zealand White rabbit. The method was designed to meet the requirements of the following:

-      OECD guidelines for the testing of chemicals No. 405 “Acute Eye Irritation/Corrosion” (adopted 24 April 2002)

-      Method B.5 Acute Toxicity (Eye Irritation) of Commission Regulation (EC) No. 440/2008

 

Result. A single application of the test material to the non-irrigated eye of two rabbits produced moderate conjuctival irritation. Both treated eyes appeared normal at the 48 -Hour observation.

 

Conclusion. The test material produced a maximum group mean score of 12.0 and was classified as a mild irritant (Class 4 on a 1 to 8 scale) to the rabbit eye according to a modified Kay and Calandra classification system.
