Test system
- Type of coverage:
- semiocclusive
- Preparation of test site:
- shaved
- Vehicle:
- unchanged (no vehicle)
- Controls:
- other: the other flank was treated the same way but without test item and served as control.
- Amount / concentration applied:
- TEST MATERIAL
- Amount applied: 0.5 ml - Duration of treatment / exposure:
- 4 h
- Observation period:
- 7 days
- Number of animals:
- 3 males
- Details on study design:

REMOVAL OF TEST SUBSTANCE
- Washing: by using a tissue moistened with tap-water and subsequently a dry tissue
- Time after start of exposure: 4 h
SCORING SYSTEM: Draize scoring system

- Irritant / corrosive response data:
- There was no evidence of a corrosive effect on the skin.
One hour after exposure to the test item, very slight or well defined erythema and very slight or slight oedema were observed in the treated skin-areas of the animals. The erythema persisted for 48 h and had resolved in the animals within 7 days after exposure. The oedema had resolved within 48 h in two animals and within 72 hours after exposure in the third animal. - Other effects:
- Remnants of the test substance were noted during the study, but had disappeared within 24 h after exposure in one animal and within 7 days in the other two animals.
No symptoms of systemic toxicity were observed in the animals during the test period and no mortality occured.
Applicant's summary and conclusion
- Interpretation of results:
- other: CLP/EU GHS criteria are not met, no classification required according to Regulation (EC) No 1272/2008
- Conclusions:
- The test item was tested for primary skin irritation/corrosion according to the OECD TG 404 (1987) and in compliance with GLP. No mortality occured and and no signs of systemic toxicity were observed. The primary erythema score (mean out of all three animals over 24, 48, and 72 h) was determined to be 1.4, whereas effects were fully reversible within the 7 days of the post exposure period. The oedema score (mean out of all three animals over 24, 48, and 72 h) was determined to be 0.67, and the effects were fully reversible within 72 h. Hence, classification for skin irritation/corrosion according to EC/1272/2008 is not warranted.
