- Remarks:
- distilled water
- Controls:
- other: a control gauze patch was applied to the contralated flank
- Amount / concentration applied:

- Executive summary:
A GLP-compliant study was performed to access the primary eye irritation potential of FAT 45155/B.

The reaction was assessed at 1, 24, 48 and 72 h intervals after administration. Under the experimental conditions employed the test substance induced reactions of the iris and conjunctiva when instilled into the conjunction sac of albino rabbits' eyes. The mean values of the readings 24 to 72 h after instillation for Cornea and Iris was ‘0’ while for redness and chemosis was 1.11 and 0.22, respectively, which are below the threshold of significance. The eye reactions observed were reversible until the end of the observation period on day 7. Based on the study result of this test, FAT 45155/B is considered as non-irritant to rabbit eye.

Additional information
Skin Irritation:
A GLP-compliant study was performed to access the primary skin irritation potential when single doses of FAT 45155/B are placed on the skin of New Zealand White rabbits. The study was carried out according to OECD guideline 404. No edema formation was observed during an observation period of 7 days. The application area was red stained up to the reading of 24 hours animals No. 420 and 408 and up to the reading of 48 hours in animal No. 534. Therefore, the evaluation of a possible slight erythema formation was impeded for animal No. 534. The mean values of the recordings 48 to 72 hours after application taken for animals No. 420 and 408 are score zero. Based on the study results, FAT 45155/B can be classified as non-irritant to rabbit skin.
Eye Irritation:
A GLP-compliant study was performed to access the primary eye irritation potential of FAT 45155/B. Two males and one female were exposed a single dose of test substance (0.1 ml or 91 mg per animal) placed in the eyes of rabbits. The reaction was assessed at 1, 24, 48 and 72 h intervals after administration. The mean values of the readings 24 to 72 h after instillation for Cornea and Iris was ‘0’ while for redness and chemosis was 1.11 and 0.22 respectively which are below the threshold of significance. The eye reactions observed were reversible until the end of the observation period on day 7. Based on the study result of this test, FAT 45155/B is considered as non-irritant to rabbit eye.
Justification for classification or non-classification
Based on the findings in the skin and eye irritation study, the test substance does not considered to be classified according to the EU Classification, Labelling and Packaging of Substances and Mixtures (CLP) Regulation (EC) No. 1272/2008 to be irritating to the skin as well eyes.
