- Irritant / corrosive response data:
- Local signs (mean values from 24 to 72 hours) consisted of grade 0.00 erythema and grade 0.00 edema. No signs of irritation were observed. No irreversible alterations of the treated skin were observed nor were corrosive effects evident on the skin.
- Other effects:
- No staining by the test article of the treated skin was observed. No clinical signs of systemic toxicity were observed in the animals during the test and observation period, and no mortality occurred.
Applicant's summary and conclusion
- Interpretation of results:
- not irritating
- Remarks:
- Migrated information Criteria used for interpretation of results: EU
- Conclusions:
- Under the conditions of this study the test material is considered to be not irritating to the skin.
- Executive summary:
The study was performed EU Method B.4 and OECD 404 guideline in accordance with GLP to assess the irritancy potential of the test material to the skin of the New Zealand White rabbit. A dose of 0.5 ml test substance (undiluted), was applied to the intact clipped dorsal skin site under a semi-occlusive dressing for 4 hours. The patch was then removed and the application site was washed to remove residual test material. Skin observations were made 1, 24, 48 and 72 hours after patch removal. A single 4-hour, semi-occluded application of the test material to the intact skin produced no irritation effects. The test material produced a primary irritation index (PII) of 0 and is considered to be non-irritating to skin. No clinical signs of systemic toxicity were observed in the animals during the test and observation period, and no mortality occurred.
