- Source of Bovine Eyes
Eyes from adult cattle (typically 12 to 60 months old) were obtained from a local abattoir as a by-product from freshly slaughtered animals. The eyes were excised by an abattoir employee after slaughter, and were placed in Hanks’ Balanced Salt Solution (HBSS) supplemented with antibiotics (penicillin at 100 IU/mL and streptomycin at 100 μg/mL). They were transported to the test facility over ice packs on the same day of slaughter. The corneas were prepared immediately on arrival.

The corneas treated with the test substance were clear post treatment and cloudy post incubation. The corneas treated with the negative control substance were clear post treatment and post incubation. The corneas treated with the positive control substance were cloudy post treatment and post incubation.

Criteria for an Acceptable Test
The positive control In Vitro Irritancy Score was within the range of 31.6 to 58.7. The positive control acceptance criterion was therefore satisfied. The negative control gave opacity of ≤3.0 and permeability ≤0.077. The negative control acceptance criteria were therefore satisfied.
Conclusion
Based on the study results, the study author concluded that no prediction of eye irritation could be made.
Applicant's summary and conclusion
- Interpretation of results:
- other: No prediction can be made based on EU CLP criteria
- Conclusions:
- Under study conditions, no prediction could be made about eye irritation potential of the test substance.
- Executive summary:
An in vitro study was conducted to determine the eye irritation potential of the the test substance, 'C18-unsatd and C22-unsatd. AAP EDM-ES' (active: 104%), using Bovine Corneal Opacity and Permeability (BCOP) method, according to the OECD Guideline 437 and EU B.47 Method, in compliance with GLP. The undiluted test substance and reference substances were applied to the test system for 10 minutes followed by an incubation period of 120 minutes. 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). The IVIS of the test substance was determined to be 29.8 which is well below the corrosive limit of 55 and above the non-corrosive limit of 3; therefore no predictions could be made. Therefore based on EU CLP criteria, no prediction could be made about eye irrtation potential of the test substance. The IVIS of the positive control was within the range of 31.6 to 58.7, therefore acceptance criterion was satisfied. The negative control gave opacity of ≤3.0 and permeability ≤0.077, therefore the negative control acceptance criteria were satisfied. The quality criteria required for acceptance of results in the test were satisfied. Under the study conditions, no prediction could be made about eye irritation potential of the test substance (Envigo, 2018).
