Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- Non irritant
- Executive summary:
The test substance was applied as a single 0.5-g dermal dose to the shaved intact skin of a single New Zealand White rabbit. Since no corrosion occurred, 2 additional rabbits were treated. The test substance, moistened with 0.3 mL of deionized water, was applied to a 6 cm² area of skin. The application area was covered with a 2-ply gauze square which was held in place with non-irritating tape and covered with porous tape for a semi-occlusive dressing. The rabbits were exposed to the test substance for 4 hours after which the test substance was removed. Test sites were evaluated by Draize for signs of dermal irritation approximately 60 minutes, and 24, 48, and 72 hours after test substance removal. The rabbit that was initially treated was also examined immediately after test substance removal.
The rabbits exhibited no dermal irritation during the study. No clinical signs of toxicity were observed, and no biologically important body weight loss occurred.
