Applicant's summary and conclusion
- Interpretation of results:
- Category 2A (irritating to eyes) based on GHS criteria
- Conclusions:
- Under the test conditions, Diethylamine modified ethoxylated trimethylolpropane triacrylate is irritating to the eyes.
- Executive summary:
In an eye irritation study conducted according to the OECD Guideline 405 and in compliance with GLP, 3 healthy male rabbits of the New Zealand White strain were exposed to 0.1 mL of Diethylamine modified ethoxylated trimethylolpropane triacrylate in one eye, while the contralateral eye remained untreated and served as control. The study was started by treatment of a single rabbit (sentinel). The two other animals were treated in a similar manner 21 days later, after considering the degree of eye irritation observed in the first animal. The eyelids were then gently held together for about one second to prevent loss of the test material, and then released. The eyes were examined 1 and 24 h after instillation. After 24 h observation, 2% fluorescein in water was instilled into both eyes of each animal to quantitatively determine corneal epithelial damage. The eyes were also examined 48 and 72 h, 7 and 14 days after the treatment. Draize (1977) scoring system was followed to grade the ocular reactions.
No symptoms of systemic toxicity were observed in the animals during the test period and no mortality occurred. Corneal injury was seen as opacity (maximum grade 1) and epithelial damage (maximum 75% of the corneal area) leads to development of pannus (neovascularisation of the cornea) in one animal 7 days after instillation. Corneal injury had resolved within 7 days in two animals and within 14 days in the other animal. Iridial irritation (grade 1) was observed in all animals and had resolved within 72 h. Irritation of the conjunctivae was seen as redness, chemosis and discharge, which had completely resolved within 7 days in one animal and within 14 days in the other two animals. Reduced elasticity of the eyelids was noted in one animal 72 h after instillation. Remnants of the test substance were present on the outside of the eyelids of one animal on Days 1, 2 and 3. Mean individual scores at 24, 48 and 72 h after exposure for the 3 animals were 1, 1, 1 for cornea score; 0.7, 0.7, 0.7 for iris score; 2.7, 2.7, 2.7 for conjunctivae score and 2.3, 2, 2 for chemosis score. In this study, Diethylamine modified ethoxylated trimethylolpropane triacrylate (ACTILANE 715) is an eye irritant on male rabbits.
Under the test conditions, Diethylamine modified ethoxylated trimethylolpropane triacrylate is Irritating to eyes.
