Any other information on results incl. tables
- The study was initiated with one rabbit (animal no. 1889). Since no marked eye irritation was seen in this animal another two rabbits were included in the study with time difference.

F - Reading after instillation of fluorescein
* Only the scores from the readings after 24, 48 and 72 h are included in the calculation of the individual mean scores
Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- Under the test conditions, Bisphenol A ethoxylate diacrylate is not classified as irritating to eyes.
- Executive summary:
In an eye irritation study conducted according to the OECD Guideline 405 and in compliance with GLP, 3 healthy female albino rabbits of the stock Chbb:HM (SPF) – Littlerussian were exposed to 0.1 mL of Bisphenol A ethoxylate diacrylate in one eye, while the contralateral eye remained untreated and served as control. The eyelids were then gently held together for one second before releasing. The eyes were examined 1 h and 24 h after instillation. After the first 24 h reading fluorescein was instilled and eyes were examined for ocular lesions. After rinsing with 20 mL 0.9% sodium chloride solution, the eyes were examined again using UV -light to detect possible corneal damage. The eyes were also examined 48 and 72 h after the treatment. Draize (1977) scoring system was followed to grade the ocular reactions.
One hour after application of the test article, animals showed conjunctival redness, chemosis and discharge different from normal. All the eyes were normal one day after instillation. Mean individual scores at 24, 48 and 72 h after exposure for the 3 animals were 0, 0, 0 for cornea score; 0, 0, 0 for iris score; 0, 0, 0 for conjunctivae score and 0, 0, 0 for chemosis score. In this study, Bisphenol A ethoxylate diacrylate is not an eye irritant on female rabbits.
Under the test conditions, Bisphenol A ethoxylate diacrylate is not classified as irritating to eyes.
