Diffuse redness (3 rabbits, score 2), slight redness (3 rabbits, score 1) and slight chemosis (3 rabbits, score 1) were observed after 1 hour. After 24 hours only mild redness was seen in 2 rabbits (score 1). All signs were reversible, and no reactions were seen at the 48-hour reading.

Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- In conclusion, pullulanase can be classified as a ‘non irritant’ to the eye.
- Executive summary:
In accordance with the OECD guideline 405, a test for eye irritation in rabbits was performed with Pullulanase, batch PPY1323.
The eyes of six animals were checked for defects or irritation before instillation and only animals without defects were used.
100 mg of Pullulanase, batch PPY1323, was placed in the conjunctival sac of the left eye by pulling the lower eyelid away from the eyeball. The lids were gently held together for about one second after instillation. The untreated eye served as control. The ocular reactions were recorded at 1, 24, 48 and 72 hours after instillation according to the specified guideline.
No corneal opacity or iris reactions were noted at any time during the test. Diffuse or slight redness (max score 2) and slight chemosis (max score 1) were observed after 1 hour. After 24 hours only mild redness was seen in 2 rabbits (score 1). All signs were reversible, and no reactions were seen at the 48-hour reading.
In conclusion, pullulanase can be classified as a 'non-irritant' to the eye.
