Applicant's summary and conclusion
- Interpretation of results:
- not irritating
- Remarks:
- Criteria used for interpretation of results: EU
- Conclusions:
- Slightly irritating according to Federal Register 38, No 187. No labelling according to EU guideline
- Executive summary:
Acute dermal skin irritation/corrosion study in the rabbits was carried out with a procedure similar to OECD guideline 404. 6 rabbits were treated on abraded skin with the test substance for 24 h and observation upto 72 h. The flank skin was shaved at an area of 6 cm x 3 cm. One half of 3 x 3 cm was abraded by means of a scarificator. A gauze pad (2.5x2.5 cm) with 500 mg pasted test substance was applied to each 3x3 cm test area.
Overall mean irritation score noted was 3 wherein the reactions were not fully reversible within 72 h.Primary irritation index score was 2.96.
