Additional information
Skin irritation:
A study was designed to assess the skin irritation potential of the test item following a single dermal application to rabbits. The study was conducted according to OECD guideline 404 and EU Methode B.4. Three rabbits were each administered a single dermal dose of 0.5 g of the test substance and observed for four days. No dermal irritation was observed following a single semi-occlusive application of the test item to intact rabbit skin for four hours.
Eye irritation:
A study was designed to assess the eye irritation potential of the test item following a single instillation into the eye of the rabbit. The study was conducted in compliance with OECD guideline 405 and EU Method B.5. Three rabbits were each administered a single ocular dose of a volume of 0.1 mL of the test substance (mean weight 61 mg) and observed for three days after instillation. A single instillation of the tets item into the eye of the rabbit elicited an ocular response confined to transient very slight to well-defined conjunctival. The mean scores (24/48/72 h) were: corneal opacity: 0, iris lesions: 0, conjunctival redness: 0.33 and conjunctival chemosis: 0.11. Responses had resolved by three days after treatment.
Justification for classification or non-classification
Classification, Labeling, and Packaging Regulation (EC) No 1272/2008
The available experimental test data are reliable and suitable for classification purposes under Regulation (EC) No 1272/2008. No skin and eye irritation was observed. As a result the substance is not considered to be classified for skin irritation or eye damage under Regulation (EC) No 1272/2008, as amended for the tenth time in Regulation (EC) No 2017/776.
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).
