Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- The test substance was only slighly irritating in 2 of 3 animals at the 24-hour observation mark. No signs of irritation remained at the 48 hour observation time.
- Executive summary:
In an in vivo GLP guideline study conducted according to US EPA Test Guideline OPPTS 870.2500 (1998) with 3 young adult female New Zealand Albino rabbits, the test substance was only slighly irritating in 2 of 3 animals at the 24-hour observation mark. No signs of irritation remained at the 48 hour observation time. Therefore, the substance was determined to not meet the criteria for classification as corrosive or irritating to the skin.
