Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- FAT 20044/A is non-irritant to rabbit skin.
- Executive summary:
The purpose of this test with FAT 20044/A was to determine the primary-irritation index, which serves as a measure of the acute irritation, provoked by the compound on the skin of the rabbits. The procedure adopted was the patch-test technique described in the "Appraisal of the Safety of Chemicals in Foods, Drugs and Cosmetics" (1959) of the US Association of Food and Drug Officials (AFDO). Six rabbits (3 males/3 females) of the Russian breed were used in the study. FAT 20044/A was applied to each side in quantities of 0.5 g. Before application a 50 % polyethylene glycol trituration (PEG 400) was made. The gauze patches were removed 24 hours after the application. The reaction of the skin was appraised upon removal and 72 hours after it, based on the evaluation scheme. The erythema and edema score in all the animals was '0', so based on the study results, FAT 20044/A is non-irritant to rabbit skin.
