Details on study design:

Approximately 24 hours before treatment, the dorsal fur was shaved with an electric clipper, exposing an area of approximately 100 square centimeters (10 cm x 10 cm). On test day 1, 0.5 g of the test article was applied to the intact skin of the shaved area. It was covered with a 3.0 cm x 3.0 cm patch of surgical gauze.

Four hours after the application, the dressing was removed and the skin was flushed with lukewarm tap water. The skin reaction was assessed at 1, 24, 48 and 72 hours intervals after the removal of the dressing, gauze patch and test article.

Details on study design:

The eyes of the animals were observed 24 hours prior to test article administration. The test article (0.1 g per animal) was placed in the conjunctival sac of the left 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 to prevent loss of the test article. The right eye remained untreated and served as the reference control. The eyes of each animal were examined 1, 24, 48 and 72 hours after administration. The irritation was assessed and the corrosive properties of the test article and the color of the treated eye were described and recorded.

Additional information

Skin irritation:

In a GLP compliant skin irritation study, performed according to OECD guideline 404, FAT 40224/C (moistened, 0.5g) was applied, semi-occlusive, to the skin of three New Zealand White rabbits for 4 hours. After 4 hours, the treated skin was flushed with water and observations were made for an additional 72 hours. The test substance showed a primary Irritation score (24, 48, 72 hours) of 0.00 and local signs (mean 1 hour to 72 hours) consisted of grade 0.0 erythema and grade 0.0 edema. In the area of application, an orange staining of the treated skin by pigment or coloring of the test article was observed. No corrosive effect was evident on the skin. Under the conditions of this experiment, the test substance was found to be not irritating or corrosive to rabbit skin.

 

Eye irritation:
