Additional information
Skin irritation:
The potential of the test item to cause acute dermal irritation or corrosion was assessed by a single topical application of 0.5 ml of the test substance to the intact skin of 3 white New Zealand rabbits for 4 hours under semi-occlusive dressing.
The average score (24 to 72 h) for irritation was calculated to be 3.3 for erythema and 2.1 for edema. Signs of skin irritation (such as edema) were reversible within 15 days after removal of the patches, while erythema and scaling were still present at study termination. Symptoms observed indicate an irritant property of the test item to the skin.
The supporting study was performed similar to the USA Federal Hazardous Substances Act (US-FHSA). The test substance was applied to 3 male and 3 female New Zealand white rabbits under occlussive conditions for 24 hours on intact and abraded skin.
The average score (24 to 72 hours) for erythema on intact skin was calculated to be 2.7 and 2.95 for edema. Signs of skin irritation were still present after 7 days of patch removal. Under the conditions of the present experiment the test item was found to cause marked irritation when applied to intact and abraded rabbit skin.
Eye irritation:
The test material was inserted in an amount of 0.1ml in the conjunctival sac of the left eye of six New Zealand White Rabbits. The right eye was not treated and served as negative control. In 3 of 6 animals approximately 30 seconds after the treatment the treated eye was flushed with 10 ml of sterile physiological saline. The eye irritation was assessed with a slit-lamp at 24, 48 and 72 hours and 4 and 7 days after treatment and was scored for each individual rabbit. Under the conditions of the present study the test item was found to possibly cause irreversible effects on the eye.
Justification for selection of skin irritation / corrosion endpoint:
Most reliable guideline study which is the basis for classification.
Justification for selection of eye irritation endpoint:
Most reliable guideline study which is the basis for classification.
Effects on skin irritation/corrosion: irritating
Effects on eye irritation: corrosive
Justification for classification or non-classification
Dangerous Substance Directive (67/548/EEC)
The available studies are considered reliable and suitable for classification purposes under 67/548/EEC. As a result the substance is considered to be classified for eye irritation and for skin irritation under Directive 67/548/EEC, as amended for the 31st time in Directive2009/2/EC.
Classification, Labelling, and Packaging Regulation (EC) No. 1272/2008
The available experimental test data are reliable and suitable for classification purposes under Regulation 1272/2008. As a result the substance is considered to be classified for eye irritation and for skin irritation under Regulation (EC) No 1272/2008, as amended for the fifth time in Directive EC 944/2013.
