- Irritant / corrosive response data:
- IRRITATION:
The primary irritation score was calculated by totaling the individual cumulative scores at 24, 48 and 72 hours and then dividing the resulting total by the number of data points. The primary irritation score was 0.22 (max. 13).
The eye reactions (mean values from 24 to 72 hours) consisted of grade 0.00 corneal opacity, grade 0.00 iris, grade 0.22 redness of the conjunctivae and grade 0.00 Chemosis of the conjunctivae.
Slight corneal opacity was seen in one animal at the 1-hour examination. Hyperemic conjunctival blood vessels were noted in all animals at the 1-hour examination and persisted in one animal through 48 hours. Slight conjunctival swelling and a slightly reddened sclera were also seen in all animals one hour after the treatment. All eye reactions were clear within 72 hours after treatment.
CORROSION
No corrosion of the cornea was observed at any of the reading times. - Other effects:
- VIABILITY / MORTALITY AND CLIMICAL SIGNS:
No clinical signs of systemic toxicity were observed in the animals during the test and observation period, and no mortality occured.
COLORATION
Red staining of the test article in eye or conjunctival sac were observed in all animals through the whole reading period (marked staining at the 1-hour examination) but did not influence the reaction reading. Red remnants of the test article in eye or conjunctival sac were observed in all animals at the 1-hour reading and still persisted in one animal at the 24-hour examination.
BODY WEIGHTS
The body weight of all rabbits were considered to be within the normal range of variability.

Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- FAT 93504/A is considered to be not irritating to the rabbit eyes.
- Executive summary:
The purpose of this primary eye irritation study was to assess the possible irritation potential when a single dose of the test article is placed in the conjunctival sac of rabbit eyes. This study was done according to the OECD Guideline 405 (Acute Eye Irritation / Corrosion). The primary eye irritation potential was investigated by instillation of 0.1 g into one eye of each of three young adult New Zealand White rabbits (1 male and 2 females). The treated eyes were not rinsed after application.The untreated eye were used as control. Scoring of irritation effects was performed approximately 1, 24, 48 and 72 hours after test article application. The scores of each animal at the following reading times (24, 48 and 72 hours) were used in calculating the respective mean values for each type of lesion. The primary irritation score was calculated by totalling the individual cumulative scores at 24, 48 and 72 hours and then dividing the resulting total by the number of data points. The primary irritation score was 0.22 (max. 13). The eye reactions (mean values from 24 to 72 hours) consisted of grade 0.00 corneal opacity, grade 0.00 iris, grade 0.22 redness of the conjunctivae and grade 0.00 Chemosis of the conjunctivae. Slight corneal opacity was seen in one animal at the 1-hour examination. Hyperemic conjunctival blood vessels were noted in all animals at the 1-hour examination and persisted in one animal through 48 hours. Slight conjunctival swelling and a slightly reddened sclera were also seen in all animals one hour after the treatment. All eye reactions were clear within 72 hours after treatment. Red staining of the test article in eye or conjunctival sac were observed in all animals through the whole reading period (marked staining at the 1-hour examination) but did not influence the reaction reading. Red remnants of the test article in eye or conjunctival sac were observed in all animals at the 1-hour reading and still persisted in one animal at the 24-hour examination. No corrosion was observed at any of the time intervals. In conclusion, FAT 93504/A is considered to be not irritating to the rabbit eyes.
