- Diet : All the animals had free acess 112 C pelleted diet (U.A.R., 91360 Villemoisson - sur - Orge, France).
- Water : Drinking water filtered by a F.G. Millipore (0.22 micron) was provided ad libitum.
- Acclimation period: At least 5 days before the beginning of the study
ENVIRONMENTAL CONDITIONS
- Temperature (°C): 18±3°C
- Humidity (%): 30 to 70%
- Air changes (per hr): Approximately 12 cycles/hour of filtered, non-recycled air
- Photoperiod (hrs dark / hrs light): 12h/12h
Test system
- Vehicle:
- unchanged (no vehicle)
- Controls:
- other: The right eye, which remained untreated, served as a control
- Amount / concentration applied:
- TEST MATERIAL
- Amount(s) applied (volume or weight with unit): A single dose of 100 mg of the test substance was introduced into the conjunctival sac of the left eye after gently pulling the lower lid away from the eyeball.
VEHICLE
No vehicle used. The test substance was used in its original form - Duration of treatment / exposure:
- A single dose
- Observation period (in vivo):
- The eyes were examined approximately one hour, 24, 48, and 72 hours after administration of the test substance and then daily until the end of the study (day 22).
- Number of animals or in vitro replicates:
- 3
- Details on study design:
- REMOVAL OF TEST SUBSTANCE
- Washing : The eye were not rinsed after administration of the test substance.
- Time after start of exposure: Not applicable
SCORING SYSTEM: Assessment of ocular damage/irritation was made approximately 1 hour and 24, 48 and 72 hours following treatment, according to the numerical evaluation given in Table 1 (from Draize J H (1977) "Dermal and Eye Toxicity Tests" In: Principles and Procedures for Evaluating the Toxicity of Household Substances, National Academy of Sciences, Washington DC p.48 to 49).
TOOL USED TO ASSESS SCORE: hand-slit lamp / biomicroscope / fluorescein

- Irritant / corrosive response data:
- Slight to severe conjunctive reactions were observed in all animals: very slight to severe chemosis, very slight to moderate redness of the conjunctivae and clear or whitish purulent discharge were noted, from Day 1 up to Day 17 at the latest.
A slight iritis was observed in two animals on Day 2: it persisted up to day 12 or 14. Reading was masked by corneal opacity in the remaining animal.
A moderate or severe corneal opacity was noted in all animals on Day 1: a slight to severe corneal opacity persisted up to the end of the observations period (Day 22) in two animals. The remaining animals was killed on Day 7 for ethical reasons, beacuse of the severity of ocular reactions.
A whitening of the conjunctivae was noted in all animals on Day 1; it persisted up to Day 17 at the lastest. Neovascularisation was noted in two animals from Day 5 up to Day 14 or from Day 7 up to the end of the observation period (Day 22) and alopecia around the eye was recorded in one animal, from Day 11 up to Day 20.

Applicant's summary and conclusion
- Interpretation of results:
- Category 1 (irreversible effects on the eye) based on GHS criteria

- Migrated information
- Conclusions:
- Under the experimental conditions and according to the classification criteria laid down in Directive 93/21/E.E.C (27th April 1993) adapting to technical progress for the eighteenth time Council Directive 67/548/E.E.C., the test substance phenylacetic acid was considered irritant when administered by ocular route in rabbits.
