- Executive summary:
The study was conducted according to EU Method B.4 (GLP study). A total of 3 New Zealand White rabbits were exposed to the test substance. According to the scores obtained from erythema and edema, the substance was determined not to be a skin irritant.
Reference
Exposure to the test substance resulted in very slight erythema in the treated skin-areas of two rabbits, which had resolved within 24 hours after exposure.
No symptoms of systemic toxicity were observed in the animals during the test period and no mortality occurred.
Endpoint conclusion
- Endpoint conclusion:
- no adverse effect observed (not irritating)

Additional information
Justification for classification or non-classification
Based on the available data (not skin irritant neither eye irritant), the substance does not need to be classified for irritation/corrosion according to the CLP Regulation (EC) no. 1272/2008.
