Applicant's summary and conclusion
- Interpretation of results:
- other: Category 2 (irritating to eyes) based on EU CLP criteria
- Conclusions:
- Under the study conditions, the test substance was determined to irritating to the eye.
- Executive summary:
A study was conducted to determine the eye irritation potential of test substance, DPHA to the rabbit according to EU Method B.5 in compliance with GLP. Three rabbits were each administered a single ocular dose of 0. 1 mL of the test substance in one eye, whereas contralateral eye remained untreated and observed for a maximum of 14 d after instillation. All animals were observed daily for signs of ill health and toxicity. Examination of the eye was made after 1 h and 1, 2 and 3 days after instillation (24, 48 and 72 h). Additional observations were made 4, 7 and 14 days after instillation. Observations of the eyes was aided by the use of a handheld light. Ocular irritation was assessed using the numerical grading system. There were no signs of toxicity or ill health in any rabbit during the observation period. Corneal opacities developed in all animals. No iridial inflammation was observed. A diffuse crimson red colouration of the conjunctivae accompanied by swelling with partial eversion of the eyelids or with the eyelids about half closed was seen in all three animals. The eyes were normal 7 or 14 d after instillation. Under the study conditions, the test substance was determined to be irritating to the eye (Parcell, 1994).
