Test system
- Vehicle:
- unchanged (no vehicle)

- not required
- Amount / concentration applied:
- 0.1 mL
- Duration of treatment / exposure:
- Eye were not flushed after installation.
- Observation period (in vivo):
- Observations post application at 1 hour and after 1, 2, 3, 4 and 7 days
- Number of animals or in vitro replicates:
- 3
- Details on study design:
- The eyes of each animal were examined prior to instillation of the test substance to ensure that there was no pre-existing corneal damage or conjunctival inflammation.

The eyelids were then gently held together for one second before releasing. The contralateral eye remained untreated and served as a control.

Classification for GHS Cat.2 is fulfilled, as:
- at least 2 of the three animals show an mean (24, 48 and 72 hr) score for corneal opacity = 1 (all three animals),
- at least 2 of the three a mean conjunctival redness of = 2 (all three),
- at least 2 of the three a mean conjunctival chemosis of = 2 (all three)
Applicant's summary and conclusion
- Interpretation of results:
- Category 2A (irritating to eyes) based on GHS criteria
- Remarks:
- Migrated information
- Conclusions:
- Oleyl diamine, dioleate was irritating in the in vivo eye irritation test in rabbits. The effects were fully reversible within 7 days. The study results indicate that the substance should be classified Cat.2 irritating to the eyes for GHS.
- Executive summary:
The eye irritation potential of Oleyl diamine, dioleate was assessed in an in vivo eye irritation study in rabbits according to OECD 405, and in compliance with GLP.
A 0.1 ml aliquot of Oleyl diamine, dioleate was placed into the lower everted lid of one eye of each animal. The eyelids were then gently held together for one second before releasing. The contralateral eye remained untreated and served as a control.
Examination of the eyes was made after 1 hour and 1, 2, 3, 4, and 7, days after instillation. Observation of the eyes was aided by the use of a handheld torch.
Results:
All three animals gave a "positive" response.
Corneal opacities developed in all three animals.
Temporary iritis was seen in one animal.
A diffuse crimson red colouration of the conjunctivae was observed in all three animals and was accompanied by considerable swelling with partial eversion of the eyelids or with the eyelids about half-closed.
The eyes were normal seven days after instillation.
There were no other lesions.
According the GHS criteria, these results indicate that the substance should be classified Cat.2 for eye irritation.
