- Executive summary:
Method
The substance was tested for irritation to the eye in rabbit, White New Zealand strain, according to OECD 405.
0.1 grams of the substance were applied to one eye and reactions (louding of the cornea surface, iris, conjunctival hyperemia, swelling) were observed for 72 hours.
Clinical signs were also observed and primary irritation score and the degree of ocular irritation were evaluated.
Conclusion
After 72 hours of observation the registering substance was considered non irritant to the eye.
