Results
- Irritation parameter:
- other: Primary eye irritation score
- Basis:
- mean
- Remarks:
- 1 male and 2 females
- Time point:
- other: 24-72 hours
- Score:
- 0
- Max. score:
- 13
- Irritant / corrosive response data:
- - IRRITATION:
Application of the test article to healthy rabbit conjunctivae resulted in a primary irritation score of 0.00. In all animals, hyperemia of the scleral blood vessels and slight to moderate watery discharge was observed. In two animals, slight to moderate swelling of the conjunctivae including the nictitating membrane was noted after one hour. All signs of irritation were reversible after 72 hours.
Any other information on results incl. tables
Viability/Mortality and clinical signs:
- No clinical signs of systemeic toxicity were observed in the animals during the test and observation period, and no mortality occured.
Coloration:
- Reversible blue staining of the cornea, conjunctivae, the sclera and the lid hairs by the test article was observed.
Body weight:
The body weight of all rabbits were considered to be within the normal range of variability.
Applicant's summary and conclusion
- Interpretation of results:
- not irritating
- Remarks:
- Migrated information Criteria used for interpretation of results: OECD GHS
- Conclusions:
- FAT 41024/B is considered to be not irritating to the rabbit eye.
- Executive summary:
This experiment was performed according to the OECD Guideline 405 (Acute Eye Irritation / Corrosion).
The primary irritation potential of the test article was investigated by instillation of 0.1 g into one eye of each of three younf adult New Zaeland White rabbits. The treated eyes were not rinsed after application.
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 ans 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 numebr of dara points. The primary irritation score was 0.00 (max 13).
In all animals hyperemia of the scleral blood vessels and watery discharge was observed. In two animals swelling of the conjunctivae
including the nictitating membrane was noted after one hour. All signs of irritation were reversible after 72 hours.
Reversible blue staining of the cornea, the conjunctivae, the sclera and the lid hairs of the treated eyes by the test article was observed in all animals.
No corrosion was observed at any of the measuring intervals.
FAT 41024/B is considered to be not irritating to the rabbit eye.
