- Irritant / corrosive response data:
- The single application of test material elicited a persistent well-defined dermal irritation in all animals with resolution complete by Day 14. The irritant response was associated with desquamation of the stratum corneum (characterised with dryness and sloughing) notable in all animals with skin thickening in two animals during the observation period with desquamation still evident at study termination. The primary irritation index was calculated to be 4.1.
- Other effects:
- No deaths occurred during the study. There was no evidence of systemic toxicity to treatment.
Applicant's summary and conclusion
- Interpretation of results:
- Category 2 (irritant) based on GHS criteria
- Conclusions:
- In the skin irritation study, conducted according to OECD 404 and in compliance with GLP, the test material elicited well-defined persistent dermal irritation in rabbits; although, the irritancy score did not meet the criteria for irritation. However, desquamation evident in two test animals at study termination on Day 14 indicates that the test material is a skin irritant (Category 2).
