Additional information
Justification for classification or non-classification
There is an in vivo skin irritation study performed acc. OECD TG 404 available, which was assessed as sufficiently reliable. At all observation times (4, 24, 48, 72 hours) and in all animals both edema and erythema scores were consistently zero.
Further, there is an reliable in vivo eye irritation study performed acc. OECD TG 405 available, which consistently revealed that the substance is not irritating to the eye. All cornea opacity, iris, and conjunctivae (redness / discharge) scores were consistently zero at all observation times (24, 48, 72 hours) and in all animals.
The test designs allow to assess the need for classification acc. Regulation 1272/2008 as skin irritant (Table 3.2.2) or eye irritant (tables 3.3.2 resp. 3.3.1). As all available scores were zero, the do not exceed the limit scores triggering classification in these tables. Hence, classification as skin or eye irritant acc. Regulation 1272/2008 is not required.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).
