Additional information

The Times model for skin irritation/corrosion was used within the QSAR Toolbox. The model indicates that the test substance is unlikely to be irritating to the skin. In an in vivo, dermal toxicity study, a single dose of the test substance was applied to the shaved, intact skin of 5 male and 5 female rats at a dose level of 5000 mg/kg of body weight. The application site was covered with a semi-occlusive dressing for 24 hours, after which the test substance was removed. The rats were observed for 14 days following application. There were no instances of oedema and only slight erythema observed during the study. The erythema would not meet GHS criteria for classifying for skin irritation. Additionally, a leave-on facial product containing 5% of the test substance was examined in a Human Repeated Insult Patch Test (HRIPT) with 48-72 h occlusive patches. No irritation reaction was observed in any of the 103 subjects. Therefore, based on the data available, the test substance is not expected to be irritating to the skin.

 

The Times model for in vivo eye irritation was used within the QSAR Toolbox. The model indicates that the test substance is unlikely to be irritating to the eye.

Justification for classification or non-classification

Based on QSAR and in vivo tests in rats and humans, the test substance is unlikely to be irritating to the skin. Based on QSAR model, the test substance is unlikely to be irritating to the eye.  Therefore, the substance does not need to be classified for skin or eye irritation according to EU Classification, Labelling and Packaging of Substances and Mixtures (CLP) Regulation (EC) No. 1272/2008.
