Interpretation of results:
GHS criteria not met
Executive summary:

100 µl (ca. 40 mg) Macrolex Blau CA 51056 = CAS 41611-76-1 was applied into the conjuctival sac of 3 rabbits. The treated eye was washed after 24 hours with physiological saline. Eyes were examinated after application of the test substance for 7 days. Cornea, iris, conjunctiva (erythema and chemosis) were scored according to Draize at 24, 48 and 72 hours. Mean values (24, 48 and 72 h) for cornea score = 0, iris score = 0, conjuctivae score = 0 and chemosis score = 0. The test substance is not irritating.
