Additional information
Skin irritation:
3,3,4,4,5,5,6,6,7,7,8,8,8-tridecafluorooctyl 2-chloropropenoic acid ester (CAS 96383-55-0) was tested for its skin irritation potential in a study according to OECD 404 in New Zealand White rabbits (van Otterdijk, 2004). The clipped skin of 3 animals was exposed to 0.5 g test material (undiluted) for 4 hours under semi-occlusive conditions. No edema reactions were observed 1, 24, 48, and 72 h after removal of the patch in any animal. At 24 h all 3 animals showed erythema reactions (score 2). At 24 h and 48 h erythema scores of 1/1/2 and 1/0/1 were observed in the animals. All erythema were fully reversed within 72 h. No symptoms of systemic toxicity were observed in the animals during the test period and no mortality occurred. No staining of the treated skin by the test substance was observed and no test substance remnants were seen. In conclusion, the test substance was not skin irritating under the experimental conditions of the study.
Eye irritation:
3,3,4,4,5,5,6,6,7,7,8,8,8-tridecafluorooctyl 2-chloropropenoic acid ester (CAS 96383-55-0) was tested for its eye irritation potential in a study according to OECD 405 in New Zealand White rabbits (van Otterdijk, 2004). The test substance (0.1 mL) was applied in one eye of 3 animals in a tiered approach (at first treatment of 1 animal, 7 days later treatment of 2 further animals). No washing was performed and the eyes were scored 1, 24, 48, and 72 h after instillation of the test substance. No effects on cornea and iris were observed in any animal at any reading time point. Slight redness (score 1-2) was observed 1 h after instillation in all 3 animals. In 1 animal the effects on the conjunctivae was fully reversible within 24 h. In the other 2 animals conjunctiva redness was observed at 24 h (score 1), but was fully reversible within 48 h. The mean values over 24, 48, and 72 h were 0 for cornea, iris and chemosis in all animals. For conjuctiva redness the mean values over 24, 48, and 72 h were 0.3 each in 2 animals and 0 in 1 animal. The effects were fully reversible within 48 h. In conclusion, the test substance was not irritating to the eyes under the experimantal conditions of the study.
Justification for selection of skin irritation / corrosion endpoint:
The reliable GLP compliant OECD Guideline study was chosen.
Justification for selection of eye irritation endpoint:
The reliable GLP compliant OECD Guideline study was chosen.
Justification for classification or non-classification
The available data on skin- and eye irritation of 3,3,4,4,5,5,6,6,7,7,8,8,8-tridecafluorooctyl 2-chloropropenoic acid ester 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.
