- STUDY DESIGN
The test substance is brought on the intact and abraded skin under a surgical patch measuring 1 inch x 1 inch. The patch were fixed to the application site by means of adhesive tape and the entire trunk of each rabbit was wrapped with an impervious material to maintain the test patches in position and to retard the evaporation of the test material.
TEST SITE
Twenty four hours prior to applying the material, the hair is removed from the back and flanks of the animals with an electric clipper in such a way as to avoid abrasions.
Six rabbits are treated on the intact skin and on the abraded skin. The abrasions are minor incisions of the stratum corneum, but not sufficiently deep to disturb the derma or to produce bleeding.
REMOVAL OF TEST SUBSTANCE
Four hours after the application, the dressing and test substance was removed.

0.1 mL of the test substance is allowed to fall on the everted lower lid of one eye of each rabbit; the upper and lower eye lid are then carefully closed and subsequently held together for at least one second before releasing, to prevent loss of material.

The eyes are not washed following instillation and the animals are released immediately.

- In an eye irritation study with rabbits, performed equivalent to OECD 405 test guideline, Gyrane caused slight redness and slight swelling of the conjunctivae in the animals.

- Executive summary:
Gyrane was tested in an eye irritation study with rabbits, performed equivalent to OECD 405 test guideline.
Eye effects caused by the test substance consisted of slight redness of the conjunctivae in five out of six animals and slight swelling of the conjunctivae in three out of six animals. Up to day 7 some of these effects cleared up completely. However, after 7 days slight redness of the conjuctivae was still seen in three out of six animals.
Although the observation period was not extended it is assumed that after 21 days the effects observed (only redness of the conjunctivae) will be reversible. The test material does not meet the critera to be classified for skin irritation according to Regulation (EC) No 1272/2008 on classification, labelling and packaging of substances according to this test.
