Applicant's summary and conclusion
- Interpretation of results:
- other: not irritating
- Conclusions:
- The overall irritation index of aluminium, 6-hydroxy-5-[(4-sulfophenyl)azo]-2-naphthalenesulfonic acid complex (CAS No: 15790-07-5) was 0.0 after 72 hours. Also aluminium, 6-hydroxy-5-[(4-sulfophenyl)azo]-2-naphthalenesulfonic acid complex (CAS No: 15790-07-5) did not produce any clinical signs of toxicity throughout the examination period of 21 days.
Hence, under the test conditions, aluminium, 6-hydroxy-5-[(4-sulfophenyl)azo]-2-naphthalenesulfonic acid complex (CAS No: 15790-07-5)can be concluded to be not irritating to New Zealand White rabbit eyes. - Executive summary:
An ocular irritation study was conducted on New Zealand white rabbits in accordance with OECD 405 to assess the irritation parameter of aluminium, 6-hydroxy-5-[(4-sulfophenyl)azo]-2-naphthalenesulfonic acid complex (CAS No: 15790-07-5) 3 female New Zealand White rabbits were used for the study. 0.1g of the undiluted test chemical was instilled in the conjunctival sac of rabbits after gently pulling the lower lid away from the eyeball. The other eye which remained untreated served as a control. The ocular lesions were evaluated at 1, 24, 48 and 72 hours after the treatment. The grades of ocular reactions (conjunctiva, cornea and iris) were recorded at each observation. To determine the reversibility of the effect the animals were observed normally for 21 days. Any other lesions in the eye viz pannus, staining were observed and scored accordingly. Examination of reactions was facilitated by use of biomicroscope and hand slit lamp. Individual animal weights before and during the study was observed.
The overall irritation index of aluminium, 6-hydroxy-5-[(4-sulfophenyl)azo]-2-naphthalenesulfonic acid complex (CAS No: 15790-07-5) was 0.0 after 72 hours.
Also aluminium, 6-hydroxy-5-[(4-sulfophenyl)azo]-2-naphthalenesulfonic acid complex (CAS No: 15790-07-5) did not produce any clinical signs of toxicity throughout the examination period of 21 days.
Hence, under the test conditions, aluminium, 6-hydroxy-5-[(4-sulfophenyl)azo]-2-naphthalenesulfonic acid complex (CAS No: 15790-07-5)can be concluded to be not irritating to New Zealand White rabbit eyes.
