Executive summary:

Eye irritation test of 6-Amino-4-hydroxy-2-naphthalene-6-sulfonic acid was conducted in rabbit. 50 mg of test chemical was instilled into theconjunctival sac of 2 rabbits. One hour after application, there was slight reddening observed, which are cleared up completely after 3 days Hence, the substance 6-Amino-4-hydroxy-2-naphthalene-6-sulfonic acid is considered to be not irritant to rabbit eye
