Additional information
The test substance was evaluated for skin and eye irritation. Five-tenths of a gram of the test substance, moistened with distilled water, was applied to a patch and then to the skin of rabbits for 4 hours. No dermal irritation was observed at 30-60 minutes and 24, 48, and 72 hours after removal of the test substance. An aliquot of 0.1 mL of the test substance was administered to 1 eye of each of 3 rabbits. There was no corneal opacity or iritis observed in any treated eye during the study. Conjunctival redness (score of 1 and/or 2), chemosis (score of 1 and/or 2) and discharge (score of 1 and/or 2) were noted in the treated eye of all three rabbits. All animals were free of ocular irritation by 72 hours.
Justification for classification or non-classification
When tested as 99.9% pure, the test substance produced no skin irritation. However, the test substance as marketed, contains an impurity which would require a Cat 2 classification for skin irritation according to the mixture rule. Therefore, the test substance is classified as Cat 2 (H315: Causes skin irritation) for skin irritation according to EU Classification, Labelling and Packaging of Substances and Mixtures (CLP) Regulation (EC) No. 1272/2008.
The test substance produced slight eye irritation, which cleared within 72 hours. Therefore, the substance does not need to be classified for eye irritation according to EU Classification, Labelling and Packaging of Substances and Mixtures (CLP) Regulation (EC) No. 1272/2008.
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.
