- Other effects:
- - Mortality/clinical signs: no clinical signs of systemic toxicity were observed in the animals during the study and no mortality occurred.
- Irritation: test article did not elicit any skin reactions at the application site at any of the observation times (all scores 0). The mean values from 24 to 72 hours were therefore 0 for erythema and 0 for oedema.
- Coloration: no staining by the test item of the treated skin was observed.
- Corrosion: no irreversible alterations of the treated skin were observed nor were corrosive effects evident on the skin.
- Body weights: body weights of all rabbits were considered to be within the normal range of variability.
Applicant's summary and conclusion
- Interpretation of results:
- other: Non classified according to the CLP Regulation (EC 1272/2008)
- Conclusions:
- Non irritant to the rabbits skin.
- Executive summary:
Method
Skin irritation study carried out according to OECD guideline 404. Semicocclusive application of 0.5 g of test substance applied on clipped intact skin of 3 rabbits (2 F and 1 M) for 4 hours. Treated skin was washed and observed for signs of oedema and erythema at 1 h, 24 h, 48 h and 72 h.
Results
No signs of skin irritation and no staining were noted.
