The skin irritation potential of PF-6 was investigated in a study according to OECD guideline 404 and GLP. The test substance (0.5 g moistened with 0.5 mL distilled water) was applied to the clipped skin of 3 young adult New Zealand White (Hsdlf:NZW) rabbits under semiocclusive conditions. The first animal was exposed to the test substance for 3 min, 1 h or 4 h, whereas in the further 2 animals treatment was performed for 4 h. The scoring of skin reactions (erythema and edema) was performed 1, 24, 48 and 72 h after patch removal. Exposure to the test substance for 3 min or 1 h did not elicit any skin reactions at the application site of the first animal at any of the observation time points. In the same animal, very slight erythema was observed 1 h after exposure to the test substance for 4 h, which was reversible within 24 h. Very slight erythema was also observed in the third animal at the 24 and 48 h, but not at the 72 h reading time point after 4 h treatment. In the second animal, no skin irritation effects were noted at any of the observation time points. No signs of systemic toxicity were seen in any of the animals tested. The mean erythema and edema scores after 24, 48 and 72 h were 0 for the first and second animal. In the third animal, the mean erythema and edema scores after 24, 48 and 72 h were 0.67 and 0, respectively.

The eye irritation potential of PF-6 was investigated according to OECD guideline 405 and in compliance with GLP. The undiluted test material (0.1 mL) was placed into the conjunctival sac of one eye of 1 New Zealand White (Hsdlf:NZW) rabbit. The other eye remained untreated and served as control. The eyes were examined and scored 1, 24, 48 and 72 h as well as 7 days after application. Single application of the test substance to the eye of one rabbit induced scattered or diffuse corneal opacity at the 24 and 48 h readings. Translucent corneal opacity was observed 72 h and 7 days post-application. In addition, a small area of opalescent corneal opacity was observed at the 72 h reading and blood stained discharge occurred 7 days post-application. Iridial inflammation was noted in the animals at all reading time points during the 7-day observation period. Moderate to severe conjunctival redness and chemosis were observed in the animal at the 24, 48 and 72 h as well as the 7 day observation time points. None of the observed effects on the treated eye was reversible within the 7-day observation period. Due to worsening reactions and signs of pain and discomfort, the animal was killed for humane reasons immediately after the 7-day observation period. The mean cornea, iris, conjunctivae and chemosis scores after 24, 48, and 72 h were 1.3, 1, 2 and 2.3 in the animal, respectively.

Additional information
Skin Irritation
The skin irritation potential of PF-6 was investigated in a study according to OECD guideline 404 and GLP (Bradshaw, 2012). The test substance (0.5 g moistened with 0.5 mL distilled water) was applied to the clipped skin of 3 young adult New Zealand White (Hsdlf:NZW) rabbits under semiocclusive conditions. The first animal was exposed to the test substance for 3 min, 1 h or 4 h, whereas in the further 2 animals treatment was performed for 4 h. The scoring of skin reactions (erythema and edema) was performed 1, 24, 48 and 72 h after patch removal. Exposure to the test substance for 3 min or 1 h did not elicit any skin reactions at the application site of the first animal at any of the observation time points. In the same animal, very slight erythema was observed 1 h after exposure to the test substance for 4 h, which was reversible within 24 h. Very slight erythema was also observed in the third animal at the 24 and 48 h, but not at the 72 h reading time point after 4 h treatment. In the second animal, no skin irritation effects were noted at any of the observation time points. No signs of systemic toxicity were seen in any of the animals tested. The mean erythema and edema scores after 24, 48 and 72 h were 0 for the first and second animal. In the third animal, the mean erythema and edema scores after 24, 48 and 72 h were 0.67 and 0, respectively.
Eye Irritation
The eye irritation potential of PF-6 was investigated according to OECD guideline 405 and in compliance with GLP (Bradshaw, 2012). The undiluted test material (0.1 mL) was placed into the conjunctival sac of one eye of 1 New Zealand White (Hsdlf:NZW) rabbit. The other eye remained untreated and served as control.

In addition, a small area of opalescent corneal opacity was observed at the 72 h reading and blood stained discharge occurred 7 days post-application. Iridial inflammation was noted in the animals at all reading time points during the 7-day observation period. Moderate to severe conjunctival redness and chemosis were observed in the animal at the 24, 48 and 72 h as well as the 7 day observation time points. None of the observed effects on the treated eye was reversible within the 7-day observation period.

Justification for classification or non-classification
The available data on eye irritation of PF-6 meet the criteria for classification as Eye Dam. 1 (H318) according to Regulation (EC) 1272/2008 and as Xi (R41) according to Directive 67/548/EEC. The available data on skin irritation of PF-6 do not meet the criteria for classification according to Regulation (EC) 1272/2008 or Directive 67/548/EEC, and are therefore conclusive but not sufficient for classification.
