- Irritant / corrosive response data:
- The substance showed a primary irritation score of 0.00, when applied to the conjunctival sac of the rabbit eye.
After one hour, moderate reddening of the conjunctivae and slight watery discharge were noted in all animals, and slight swelling was noted in two of three animals. All signs of irritation were reversible after 24 hours.
No corrosion of the cornea was observed at any of the reading times. - Other effects:
- - No clinical signs of systemic toxicity were observed in the animals during the test and observation period, and no mortality occurred.
- Light orange staining of the sclera was seen in all animals after one hour. Light orange staining of the conjunctivae was noted after one and 24 hours in two of three animals.
- The body weight of the animals was within the normal range of variability.
Applicant's summary and conclusion
- Interpretation of results:
- not irritating
- Remarks:
- Migrated information Criteria used for interpretation of results: EU
- Conclusions:
- Based upon the referred classification criteria, the substance is classified as "not irritating" to the eye.
- Executive summary:
The primary irritation potential of the substance was investigated according to Directive 92/69 EEC, B.5. "Acute Toxicity - Eye Irritation", July 31, 1992, U. S. Environmental Protection Agency, Code of Federal Regulations 40, Part 798, Health Effects Testing Guidelines, Subpart E, Specific organ/tissue toxicity, Paragraph 798.4500 "Primary eye irritation", revised as of July 1, 1993, and OECD Guidelines for Testing of Chemicals, Section 4, number 405 "Acute Eye Irritation / Corrosion", adopted February 24, 1987.
0.1 g of the test item was instilled undiluted into one eye of each of three young adult New Zealand rabbits. The treated eyes were not rinsed after application. Scoring of irritation effects was performed approximately 1, 24, 48 and 72 hours after test article application. The scores of each animal at the following reading times (24, 48 and 72 hours) were used in calculating the respective mean values for each type of lesion. The primary irritation score was calculated by totalling the individual cumulative scores at 24, 48 and 72 hours and then dividing the resulting total by the number of figures.
The primary irritation score was 0.00 (max. 13). After one hour, reddening of the conjunctivae and watery discharge were noted in all animals, and swelling was noted in two of three animals. All signs of irritation were reversible after 24 hours. Light orange staining of the sclera was seen in all animals after one hour. Light orange staining of the conjunctivae was noted after one and 24 hours in two of three animals.
No corrosion was observed at any of the measuring intervals.
Based upon the referred classification criteria, the substance is classified as "not irritating" to the eye.
