- rabbit
- Strain:

- caged individually
Test system
- Vehicle:
- not specified
- Controls:
- yes, concurrent no treatment
- Amount / concentration applied:
- 100 mg
- Duration of treatment / exposure:
- No washed
- Observation period (in vivo):
- eyes were examined at 24, 48, 72 hours and 7 days after instillation of the test material.
- Number of animals or in vitro replicates:
- 6 rabbits
- Details on study design:
- SCORING SYSTEM: the FDA-scoring scale was used to grade the severity of eye reactions.
positive reactions were: opacity of the cornea, ulceration of the cornea, inflammation of the iris, slight circumcorneal injection or if such substances produce in the conjunctivae an obvious swelling with partial eversion of the lids, a diffuse deep-crimson red with individual vessels not easily discernable.
The test was considered positive if four or more of the animals in the test group of 6 rabbits exhibit a positive reaction.
If two or three animals exhibited a positive reaction, the test is repeated.
reading materials: binocular magnifying glass; diagnostic of corneal damages : staining the eyes of the animals with fluorescein-impregnated papers. After flushing the excess fluorescein solution, the eyes are examined in a dark room under ultraviolet illumination.

Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- Didecanoyl peroxide was not considered to be eye irritant.
- Executive summary:
The potential of didecanoyl peroxide to induce ocular irritation was evaluated in rabbits following a technique similar to OECD 405 guideline.
A single dose of 100 mg of pure substance was instilled into the conjunctival sac. The other eye was not treated and served as control. The eyes were not rinsed after administration of the test item.
Ocular reactions were observed approximately 24, 48, 72 hours and 7 days after the administration. The scores for chemosis, redness of the conjunctiva, iris lesions and corneal opacity were calculated for each animal.
Scores calculated for each animal over 24, 48 and 72 hours were 0 for cornea and iris, and 0 or 1 for redness and chemosis of the cunjonctivae. Otherwise all signs were fully reversible within 7 days.
Under these experimental conditions, didecanoyl peroxide was slightly irritating when administered by ocular route to rabbits.
