Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- Under the test conditions, the test substance was considered to be non-irritating to rabbit skin
- Executive summary:
A study was conducted to assess the skin irritation potential of test substance to the rabbit skin according to EU Method B.4. and OECD Guideline 404 in compliance with GLP.
Three animals were treated with 0.5 g of the test substance pasted with 0.5 mL Tylose H 4000 G4 Pha (0.5 % in deion. water) using semi-occlusive patches for 4 h. After the exposure period all remnants of the test substance were carefully removed from the skin with warm tap water. The skin was evaluated for erythema, eschar formation and edema numerically according to the score of Draize system for up to 72 h after patch removal.
No signs of irritation were observed during the whole observation period.
Under the test conditions, the test substance was considered to be non-irritating to rabbit skin.
