The test substance was applied under a 6.25 cm2 patch to intact skin on each animal. The patches were covered by an overlapping patch of adhesive plastic. The whole area was then bound by occlusive tape (Acrylastic, Beiersdorf and Co.) wrapped round the entire trunk of the animal.
TEST SITE
The rabbits were prepared by shaving the skin of the back free of hair. The left and right site of the back were split up in four patch test areas and two areas were abraded.

Additional information
In a skin irritation study performed according to OECD test guideline 404, the (moistened) substance (0.5 g) was applied onto the shaved skin of three rabbits using occlusive dressings for 4 hours. Under the conditions of this study, no irritation was observed for 72 hours. The test substance caused no erythema and no edema on the intact skin test sites. No signs of systemic intoxication were observed during the study period.

Justification for selection of skin irritation / corrosion endpoint:
One study available with Klimisch reliability 2. The study has been performed equivalent or similar to OECD 404 guideline. Study has however limited information about substance identity and was not performed according to GLP guidelines.
Justification for selection of eye irritation endpoint:
One study available with Klimisch reliability 2. The study has been performed equivalent or similar to OECD 405 guideline. Study has however limited information about substance identity and was not performed according to GLP guidelines.
Justification for classification or non-classification
According to the available data, sodium ferrocyanide does not have to be classified for skin and eye irritation according to CLP Regulation (EC) No. 1272/2008.
