At the readings made at 24, 48 and 72 hours, there was:
- discernible opacity or ulceration of the cornea other than a slight dulling of the normal luster.
- inflammation of the iris other than slight deepening of the folds, or slight circumcorneal injection.
- diffuse, deep-crimson red appearance of the conjunctivae, with individual vessels not easily discernible.
- obvious swelling of the conjunctivae, excluding cornea and iris, with partial eversion of the lids.
- no destruction or irreversible change of any tissue in 24 hours, or less.
Applicant's summary and conclusion
- Interpretation of results:
- Category I
- Remarks:
- Migrated information Criteria used for interpretation of results: EU
- Conclusions:
- This test item is irritating to rabbit eyes. Therefore, precautions should be observed to avoid its introduction into or near the eyes.
- Executive summary:
0.1 g Butanedioic acid, sulfo-, 1,4 -dicyclohexyl ester, sodium salt containing 80% active ingredient was introduced into the conjunctival sac of 6 rabbits. Scoring according to Draize et al. (1944) after 24, 48 and 72 hours demonstrated a mean cornea score of 17.6/80, a mean iris score of 5/10 and a mean conjuctivae score of 14/20. At the readings made at 24, 48 and 72 hours, there was discernible opacity or ulceration of the cornea other than a slight dulling of the normal luster,inflammation of the iris other than slight deepening of the folds, or slight circumcorneal injection, diffuse, deep-crimson red appearance of the conjunctivae, with individual vessels not easily discernible and obvious swelling of the conjunctivae, excluding cornea and iris, with partial eversion of the lids. It was concluded that the test item produces irritation of rabbit eyes. Therefore, precaution should be observed to avoid its introduction into or near the eyes.
