Any other information on results incl. tables
Corneal Opacity and Permeability Measurement
Individual and mean corneal opacity measurements and individual and mean corneal permeability measurements are given in Table 1.
Corneal Epithelium Condition
The condition of each cornea post treatment is given in Table 2.
The corneas treated with the test item were cloudy post treatment. The corneas treated with the
negative control item were clear post treatment. The corneas treated with the positive control
item were cloudy post treatment.
In Vitro Irritancy Score
The In Vitro irritancy scores are summarized as follows:
Treatment In Vitro Irritancy Score
Test Item 42.4
Negative Control 9.4
Positive Control 93.6
Criterion for an Acceptable Test
The positive control In Vitro Irritancy Score was within the range of 65.9 to 140.8.
The positive control acceptance criterion was therefore satisfied.
Applicant's summary and conclusion
- Interpretation of results:
- not irritating
- Remarks:
- Migrated information Criteria used for interpretation of results: OECD GHS
- Conclusions:
- 2-Fluoro-5-(methylsulfonyl) benzoic acid (CAS Number 247569-56-8) was considered not to be an ocular corrosive or severe irritant.
However the IVIS was 42.4 which indicated that although the test item was not considered to be a severe ocular irritant or corrosive, according to
OECD Guidelines for the Testing of Chemicals No. 437, the test item can be presumed to have the ability to induce some degree of ocular irritation. - Executive summary:
Introduction
A study was performed to assess the ocular irritancy potential of the test item to the isolated bovine cornea.
Method
The test item was applied at a concentration of 20% w/v in 0.9% w/v sodium chloride solution for 240 minutes.
Negative and positive control items were tested concurrently.
The two endpoints, decreased light transmission through the cornea (opacity) and increased passage of sodium
fluorescein dye through the cornea (permeability) were combined in an empirically derived formula
to generate an In Vitro Irritancy Score (IVIS)
Interpretation
A test item that induces an In Vitro Irritancy Score 55.1 is defined as an ocular corrosive or severe irritant.
Results
The In Vitro irritancy scores are summarized as follows:
Treatment In Vitro Irritancy Score
Test Item 42.4
Negative Control 9.4
Positive Control 93.6
Conclusion
2-Fluoro-5-(methylsulfonyl) benzoic acid (CAS Number 247569-56-8) was considered not to be an ocular corrosive or severe irritant.
However the IVIS was 42.4 which indicated that although the test item was not considered to be a
severe ocular irritant or corrosive, according to OECD Guidelines for the Testing of Chemicals No.
437, the test item can be presumed to have the ability to induce some degree of ocular irritation.
