Test system

Vehicle:

Amount / concentration applied:
0.1 ml (as supplied).
Duration of treatment / exposure:
72 hours.
Observation period (in vivo):
72 hours.
Number of animals or in vitro replicates:
3.
Details on study design:
REMOVAL OF TEST SUBSTANCE
- Washing (if done): No.

SCORING SYSTEM:
Assessment of ocular damage/irritation was made approximately 1 hour and 24, 48 and 72 hours following treatment, according to the grading in the test guideline. The result was classified according to EU classification system.

TOOL USED TO ASSESS SCORE: The light source from a standard ophthalmoscope.

OTHERS
Immediately before the start of the test, both eyes of the provisionally selected test rabbits were examined for evidence of ocular irritation or defect with the aid of a light source from a standard ophthalmoscope. Only animals free of ocular damage were used. Initially, a single rabbit was treated. Immediately after administration of the test material, an assessment of the initial pain reaction was made according to the six point scale shown in Table 1. After consideration of the ocular responses produced in the first animal, two additional animals were treated.

Applicant's summary and conclusion

Interpretation of results:
other: not classified
Remarks:
Criteria used for interpretation of results: EU
Conclusions:
The test material does not meet the criteria for classification according to EU classification system (Council Directive 67/548/EEC and Regulation (EC) No 1272/2008).
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)

§        Commission Directive 92/69/EEC Method B5 Acute Toxicity (Eye Irritation)

 

Result. A single application of the test material to the non-irrigated eye of three rabbits produced minimal conjunctival irritation. All treated eyes appeared normal at the 48-hour aboservation.

 

Conclusion. The test material does not meet the criteria for classification according to EU classification system (Council Directive 67/548/EEC and Regulation (EC) No 1272/2008).
