Under test conditions, effects were fully reversible within 8 days.

Interpretation of results:
not irritating
Remarks:
Migrated information Criteria used for interpretation of results: EU
Conclusions:
Under test conditions, Calcium Acetate was not irritating for the eyes of rabbits.
Executive summary:

The Acute eye irritation test was performed on Vienna White rabbits (males and females). Ca. 53 mg of Calcium Acetate was applied to the conjunctival sac of the right eye of 6 animals. The left eye served as the untreated control. Assessment of the irritant effect was made 1 h, 24 h, 48 h, 72 h, and 8 days after test substance application.

Under test conditions, Calcium Acetate was not irritating for the eyes of rabbits.

Endpoint conclusion
Endpoint conclusion:
no adverse effect observed (not irritating)
