Description of key information
The primary skin irritation potential of the test item was investigated according to OECD test guideline no. 404. The test item was applied by topical semi-occlusive application of 0.5 g to the intact left flank of rabbits. The duration of treatment was four hours. The scoring of skin reactions was performed 1, 24, 48 and 72 hours, as well as 7, 10 and 14 days after removal of the dressing.
The mean erythema/eschar score of the three animals was 0.00, 0.33 and 0.00, respectively and the mean oedema score was 0.00 for all three animals.
Effects were reversible and were no longer evident 48 hours after treatment for all animals. However, staining by the red test item prevented the assessment of a possible erythema in all animals one hour after treatment. The slight to marked staining of the treated skin was noted in all animals throughout the whole study. No corrosive effects were noted on the treated skin of any animal and no clinical signs were observed.
A study according to OECD Guideline 405 and EU Method B.5 was performed to investigate the irritation potential to the rabbit eye.
One and 24 hours after treatment the conjunctivae of the animals showed definitely injected blood vessels up to a diffuse crimson red colour. Additionally, a very slight swelling and slightly coloured eye discharge (from intensely red substance) were
observed in one animal one hour after treatment. Fourty-eight hours after treatment all signs of irritation had disappeared.As the mean values of the observed eye responses fall below the critical values for classification according to the criteria of Regulation (EC) No 1272/2008, the test material is not irritating to eyes.

- Interpretation of results:

- Conclusions:
- According to the classification criteria of Regulation (EC) No 1272/2008 the test item is not irritating to skin under these test conditions.
- Executive summary:
The primary skin irritation potential of the test item was investigated according to OECD test guideline no. 404. The test item was applied by topical semi-occlusive application of 0.5 g to the intact left flank of each of three young adult New Zealand White rabbits. The duration of treatment was four hours. The scoring of skin reactions was performed 1, 24, 48 and 72 hours, as well as 7, 10 and 14 days after removal of the dressing.
The mean score was calculated across 3 scoring times (24, 48 and 72 hours after patch removal) for each animal for erythema/eschar grades and for oedema grades, separately. The mean erythema/eschar score of the three animals was 0.00, 0.33 and 0.00, respectively and the mean oedema score was 0.00 for all three animals.
The application of the test item to the skin resulted in mild, early-onset and transient signs of irritation such as redness. These effects were reversible and were no longer evident 48 hours after treatment for all animals. However, staining by the red test item prevented the assessment of a possible erythema in all animals one hour after treatment. The slight to marked staining of the treated skin was noted in all animals throughout the whole study, effectively. No corrosive effects were noted on the treated skin of any animal at any of the measuring intervals and no clinical signs were observed.
Thus, the test item did not induce significant or irreversible damage to the skin.
Therefore, the test item has not to be classified for skin irritation according to Regulation (EC) No 1272/2008.
- Endpoint:
- skin irritation: in vitro / ex vivo
- Data waiving:
- study scientifically not necessary / other information available
- Justification for data waiving:
- an in vitro skin irritation study does not need to be conducted because adequate data from an in vivo skin irritation study are available
