- Humidity (%): 30% - 70%
- Photoperiod (hrs dark / hrs light): 12 hour light/12 hour dark cycle
Test system
- Vehicle:
- unchanged (no vehicle)
- Controls:
- other: identical animal, left eye
- Amount / concentration applied:
- Amount: 0.1 mL of the test item was administered per eye
- Duration of treatment / exposure:
- Single instillation into the conjunctival sac of the right eye, test item was not rinsed
- Observation period (in vivo):
- 72 hours
- Number of animals or in vitro replicates:
- 3 female rabbits
- Details on study design:
- ADMINISTRATION: The test was performed initially using one animal. As no corrosive or severe irritant effects were observed in this animal, 2 further
animals were employed 24 hours after start of the initial test.
0.1 mL of the test item was administered per eye and tested in three animals.
The test item was placed into the conjunctival sac of the right eye of each animal after gently pulling the lower lid away from the eyeball. The lids were
then gently held together for about one second in order to prevent loss of the material. The left eye, which remained untreated, served as a control.
REMOVAL OF TEST SUBSTANCE
- Washing: test item was not rinsed
TOOL USED TO ASSESS SCORE: eyes were examined ophthalmoscopically with a slit lamp prior to the administration and 1, 24, 48 and 72 hours after the administration. The eye reactions were observed and registered.
At 24 hours after the administration, the eyes were treated additionally with fluorescein and examined.

Applicant's summary and conclusion
- Conclusions:
- The test substance was n o n - i r r i t a t i n g to eyes, hence, no labelling is required.
- Executive summary:
The purpose of this study was to obtain information on the influence of the test item on rabbit eyes (irritation/corrosion test), according to OECD guideline 405, EC method B.5. and OCSPP guideline 870.2400.
Under the present test conditions a single administration of the test item per animal into the conjunctival sac of the right eye of three rabbits did not cause any changes.
Conjunctival redness, corneaeandirises were not affected by instillation of the test item. There were no systemic intolerance reactions.Therefore, according to the EC Regulatiom 1272/2008 and subsequent regulations on classification, labelling and packaging of substances and mixtures, the test item is non-irritating to eyes, hence, no labelling is required.
