Amount / concentration applied:
TEST MATERIAL
- Amount(s) applied: 0.1 g of solid substance
Duration of treatment / exposure:
The test sample was applied into the conjunctival sac of one eye of each rabbit.The upper and lower eyelids were held together for several seconds, to avoid any loss of test sample.
Observation period (in vivo):
7 days. The effects were recorded after 1h, 24h, 48h and till 7 days after treatment.
Number of animals or in vitro replicates:
3 males albino rabbits.
Details on study design:
REMOVAL OF TEST SUBSTANCE
- Washing (if done): 24 hours after testing the treated eye was washed with saline solution.

SCORING SYSTEM: DRAIZE,J.H.; The Appraisal of the Safety of Chemicals in Foods, Drugs, and Cosmetics, pp. 49 - 52. Association of Food and Drug Officials of the United States, Topeka,Kansas, 1965

TOOL USED TO ASSESS SCORE: Ophthalmoscopy. For the assessment of damages a drop of fluorescein solution was put in the eye, the eye was washed and then was examined by UV-light.

Irritant / corrosive response data:
The only adverse effects observed during the study were:
- redness (level 1) 24h after exposure only in animal 3 that was fully reversible after 72h
- some liquid excretion from the eye of each of three animals 1h after exposure but fully reversible after 24h for all animals.
The observation after 24h, 48h, 72h and 7 days showed no sign of cornea opacity, no effect on iris and no chemosis for none of the three rabbits.

Applicant's summary and conclusion

Interpretation of results:
other: not eye irritant according to the CLP Regulation (EC n.1272/2008)
Conclusions:
The substance is not eye irritating according to the CLP Regulation (EC n. 1272/2008).
Executive summary:

The substance has been tested for eye irritation on three male albino rabbits.

The study was conducted according to the OECD Guideline N. 405. The eye treated was washed 24h after exposure with saline solution.

The only adverse effects observed during the study were:

- redness (level 1) 24h after exposure only in animal 3 that was fully reversible after 72h

- some liquid excretion from the eye of each of three animals 1h after exposure but fully reversible after 24h for all animals.

The observation after 24h, 48h, 72h and 7 days showed no sign of cornea opacity, no effect on iris and no chemosis for none of the three rabbits.

The substance is not eye irritating according to the CLP Regulation (EC n. 1272/2008).
