- Amount / concentration applied:
- TEST MATERIAL
- Amount(s) applied (volume or weight with unit):
A volume of 0.1 ml of the test material, which was found to weigh approximately 66 mg (as measured by gently compacting the required volume into
an adapted syringe) was placed into the conjunctival sac of the right eye.
- Duration of treatment / exposure:
- 7 Days
- Observation period (in vivo):
- 7 Days
- Number of animals or in vitro replicates:
- 2
- Details on study design:
- REMOVAL OF TEST SUBSTANCE
- Washing (if done): Not applicable
SCORING SYSTEM:
Assessment of ocular damage/irritation was made approximately 1 hour and 24, 48 and 72 hours following treatment.
Any other ocular effects were also noted
Interpretation of Results:
The numerical values corresponding to each animal, tissue and observation time were recorded. The data relating to the conjunctivae were designated by the letters A (redness), B (chemosis) and C (discharge), those relating to the iris designated by the letter D and those relating to the cornea by the letters E (degree of opacity) and F (area of cornea involved). For each tissue the score was calculated as follows:
Score for conjunctivae = (A + B + C) x 2
Score for iris = D x 5
Score for cornea = (E x F) x 5

The test material did not meet the criteria for classification as irritant according to EU labelling regulations Commission Directive 2001/59/EC (based on the mean scores for each animal).
Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Remarks:
- Criteria used for interpretation of results: EU
- Conclusions:
- The test material did not meet the criteria for classification as irritant according to EU labelling regulations Commission Directive 2001/59/EC.
- Executive summary:
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)
Method B5 Acute Toxicity (Eye Irritation) of Commission Directive 2004/73/EC
Result. A single application of the test item to the non-irrigated eye of two rabbits produced iridial inflammation and moderate conjunctival irritation. Both treated eyes appeared normal at the 7-Day observation.
Conclusion. The test material did not meet the criteria for classification as irritant according to EU labelling regulations Commission Directive 2001/59/EC.
