Additional information
Skin irritation
In a primary dermal irritation study, young adult Vienna White rabbits were dermally exposed to 0.5 mL of the undiluted test substance for 20 hours to the shaved dorsal or lateral part of the back under an occlusive dressing (BASF AG, 1971). Animals then were observed for 8 days. Irritation was scored by a BASF internal system after 24 hours. The results were converted into the Draize scheme. After a 20-hour application very slight erythema was observed in both animals with a mean score of 0.33 (24, 48, 72 h). No oedema was observed in either of the animals. After 8 days the erythema had resolved. The substance is regarded as not irritating to the intact skin of rabbits.
Eye irritation
In a second primary eye irritation study, 0.05 mL of the undiluted test substance was instilled into the conjunctival sac of two Vienna White rabbits (BASF AG, 1971). The test substance was not washed and the adjacent eye served as a control. Animals were observed for 8 days. Irritation was scored after 24 hours with a BASF internal system. The results were converted into the Draize system. The test substance caused slight conjunctival redness in both animals after 24 hours. A mean conjunctivae score of 1 (24, 48, 72 h) was determined for both animals. The redness had resolved after 8 days. No other eye effects were observed in both animals. The test substance is regarded as not irritating to the eye.
Justification for selection of skin irritation / corrosion endpoint:
Scientifically acceptable study report. Basic data given.
Justification for selection of eye irritation endpoint:
Scientifically acceptable study report. Basic data given.
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 does not need to be classified and labelled as eye or skin irritating under Directive 67/548/EEC, as amended for the 31st time in Directive 2009/2/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 does not need to be classified and labelled as eye or skin irritating under Regulation (EC) No 1272/2008, as amended for the sixth time in Regulation EC No 605/2014
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
