single exposure
Observation period (in vivo):
1, 24, 48 and 72 hours after administration
Number of animals or in vitro replicates:
2 females and 1 male
Details on study design:
A single dose was administered to the left eye of each animal. The right eye remained untreated and was used as the reference control. The application volume was 0.1 ml per animal.
For observation, the eye were not rinsed.

OBSERVATIONS :
-viability : daily
-Body weight : pre-test, day 1 and at the termination of test
-Eye reaction: 1h, 24h, 48h and 72h after administration

The study was terminated 72 hours after administration of the test article.
All rabbits were killed at the end of the observation period.
No macroscopic organ examination was performed.

Irritant / corrosive response data:
The test article showed a primary irritation score of 8.1 when applied to the rabbit eye mucosa.
In the area of application, no discoloration of the cornea and conjunctivae which could be related to effects of the test article was observed.
Opaqueness of the cornea was observed in any animal during the observation period.
Other effects:
No acute toxic symptoms were observed in the animals during the test period, and no mortality occurred.
The body weight fain of all rabbits was similar.

Applicant's summary and conclusion

Interpretation of results:
Category 1 (irreversible effects on the eye) based on GHS criteria
Conclusions:
Based on these results, Tetrahydrofurfuryl acrylate is considered to be severely irritating to the eyes of rabbit.
Executive summary:

The purpose of this primary eye irritation study was to assess possible irritation potential when single doses of Tetrahydrofurfuryl acrylate are placed in the conjunctival sac of rabbit eyes.

Under the conditions of this experiment, Tetrahydrofurfuryl acrylate was found to cause a primary irritation score of 8.1 when applied to the rabbit eye mucosa.

The eye effects are not reversible. In the area of application, no discoloration of the cornea and conjunctivae was observed which could be related to effects of the test article. Opaqueness of the cornea was observed in any animal during the observation period.

Based on these results, Tetrahydrofurfuryl acrylate is considered to be severely irritating to the eyes of rabbit.
