Any other information on results incl. tables
In the original assessment of the study a primary irritation index of 0.5 based on readings after 24, 48, and 72 hours was reported. (PII = Sum of all reactions/(Number of animals*Number of reading time points)
Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- In conclusion, the test substance showed no skin irritating potential
- Executive summary:
In a study according to OECD TG 404 (adopted 1981, GLP), the skin irritating potential of the test substance was observed in 4 male Kleinrusse rabbits. The rabbits were treated with 0.5 mL of the undiluted test substance for 4 hours under occlusive conditions. Readings were performed 1, 24, 48, and 72 hours after application. An erythema mean score of 0.5 was calculated from the results after 24, 48, and 72 hours. The findings were fully reversible within 72 h. The corresponding edema score was 0. In conclusion, the test substance showed no skin irritating potential
