Endpoint summary
Administrative data
Description of key information
Two studies in rabbits were performed to evaluate irritating or corrosive properties of the test material to skin or eyes (OECD guideline 404 and 405). Occlusive application of the test material to intact rabbit skin for 24 hours resulted in transient slight reactions on animals skin which recovered within 72h. A single instillation of the test material into the eye of the rabbit elicited slight, transient chemosis and redness of conjunctiva which was fully reversible within three days. The test substance is therefore not considered to be irritant.

Additional information
Procedure and observation
Two studies were performed to evaluate irritating potential of the test material to skin or eyes. In the first study, four female rabbits were each administered a single dermal dose of 0.5 ml. Occlusive application of the test material to intact rabbit skin for 24 hours resulted in transient slight reactions on animal skin which recovered within 72h.
In a second study, four rabbits were each administered a single ocular dose of 0.1 ml of the test substance and observed for seven days after instillation. A single instillation of the test material into the eye of the rabbit elicited slight, transient chemosis and redness of conjunctiva which was fully reversible within three days.
Discussion
Application of the test substance onto skin or installation into eyes did not cause corrosion or irritation. The test substance is therefore not considered to be irritant.
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 not considered to be classified as irritating for skin or eyes under Directive 67/548/EEC.
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 not considered to be classified for irritation under Regulation (EC) No. 1272/2008 as amended for the fifth time in Directive EC 944/2013.
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.
