Additional information
Skin irritation
The substance was tested in a skin irritation test in female rabbits (OECD TG 404). New Zealand White rabbits were exposed to 0.5 mL of the substance for 4 hours in a semiocclusive manner. Very slight erythema, with or without very slight oedema was seen in two animals 24 and 48 hours after removal of the dressing. The observations were fully reversible within 72 hours. Average erythema and edema scores (24/48/72 hr) were 0, 0.67 and 0.67 and 0, 0.33 and 0.33, respectively. Based on these results, the substance does not cause skin irritation.
Eye irritation
The substance was tested in an in vivo acute eye irritation study (OECD TG 405). Three female rabbits were exposed to the substance for a duration of 1 hour using a single application of 0.1 mL. The treatment was followed by an observation period of 14 days. No corneal damage or iridial inflammation was observed. Conjunctival inflammation was observed in all three animals, but eyes had returned to normal three days after instillation. Average scores for conjunctival irritation (redness) were 0.67 for all animals over the 24/48/72 -hour observations. Iris, opacity and chemosis scores were 0 for all animals over the entire observation period. Based on these results, the substance is not an eye irritant.
Respiratory irritation
There are no occupational or consumer data indicating respiratory tract irritation. There are also no relevant experimental guidelines or results available that indicate respiratory irritation, therefore respiratory irritation is not anticipated. The ECHA guidance (R7a: 7.2.12.1, 2017) presents that respiratory irritation may be indicated when the substance is a severe irritant. Because the substance is not a skin or eye irritant it is not likely to be a respiratory irritant.
Justification for classification or non-classification
The substance does not have to be classified for skin, eye or respiratory irritation according to EU CLP (EC no. 1272/2008 and its amendments).
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.
