Executive summary:

Method

The procedure used was the test for eye irritants described in the " Hazardous Substances Regulations" under the U.S..A. Federal Hazardous Substances Labelling Act Sect. 191.12 (February 1965), with slight modification.

The test was performed on 3 male and 3 female rabbits. 0.1 ml was inserted into the conjunctival sac of the left eye of 6 rabbits and

the lids were gently held open for one second. The right eye remained untreated and served as a control.

Results

No signs of irritation were observed in none of the animals therefore the substance resulted not irritant to the eye, under this test conditions.
