Executive summary:

The aim of this study was to determine the potential of FAT 40554 to induce irritation to rabbits skin. The study was carried out according to GLP methodology and OECD Guideline 404; 92/69/EEC, B.4.

One half of the test material was spread on the 1 inch square lint patch and applied to the intact skin of 3 rabbits with an occlusive tape for 4 hours.

At the end of exposure period, the patches were removed from the skin and the treated area was wiped to remove any remaining material by absorbent cotton dipped in acetone.

Skin reactions of erhthema and edema were scored 0.5, 24, 48 and 72 hours after removal of patch according to the method of Draize. The evaluation of irritation potency of the test material was performed by using primary irritation score.

No skin reactions such as erythema and edema were observed in any rabbits during the observation period. primary irritation score was 0. Therefore, the irritation potential of the material was judged to be negative.

According to the EEC classification of the results obtained 0.5 to 72 hours after removing the bandages FAT 40554 can be classified as non-irritant in albino rabbits.

Executive summary:

The purpose of this study was to determine the eye irritating potency of FAT 40554

The study was performed according to GLP methodology and OECD guideline 405; 92/69/EEC, B.5.

3 rabbits were used to performed the test (1 males and 2 females). 100 mg of FAT 40554 was placed into the conjunctival sac of the left eye of each animal, after gently pulling away the lower lid from the eyeball. The lids were then held together for about one second in order to prevent loss of the test article. The right eye remained untreated and served as a control. The animals were checked daily for systemic symptoms and mortality.

The ocular reactions were evaluated 1, 24, 48, and 72 hours after the instillation of FAT 40554 according to the OECD scoring system.

FAT 40554 is considered to be non-irritant to the eyes rabbits.

Endpoint conclusion

Eye:

The purpose of this study was to determine the eye irritating potency of FAT 40554. The study was performed according to GLP methodology and OECD guideline 405; 92/69/EEC, B.5.

3 rabbits were used to performed the test (1 males and 2 females). 100 mg of FAT 40554 was placed into the conjunctival sac of the left eye of each animal, after gently pulling away the lower lid from the eyeball. The ocular reactions were evaluated 1, 24, 48, and 72 hours after the instillation of FAT 40554 according to the OECD scoring system.

The test material induced slight congestion in iris, slight redness and very slight chemosis in conjuctiva in all rabbits one hour after application. At 24 hours after application, very slight opacity in cornea and slight to moderate redness in conjuctiva in all rabbits, very slight chemosis and moderate to severe discharge in conjuctiva in 2 rabbits.

These reactions disappeared in all rabbits after 72 hours of application. The maximum mean total of these irritation reactions calculated was 15.6 at 24 hours of post-application.

FAT 40554 is considered to be non-irritant to the eyes rabbits.
