Any other information on results incl. tables
OBSERVATIONS:
Clinical / skin:
No clinical signs of toxicity or other lesions were observed. No erythema or oedema were evident at the dose site of any animal following exposure, therefore the result of the PII of 0.0 was calculated.
Mortality:
All animals survived to the end of the experimental phase.
Applicant's summary and conclusion
- Conclusions:
- Under the conditions of this study, the test material returned a PII of 0.0 and is therefore considered non-irritating.
- Executive summary:
In a primary dermal irritation study, 6 young adult male New Zealand rabbits were exposedviathe dermal route to 0.5 mL of MKH 3586/animal. The test material was administered semi occluded as supplied (moistened with a small amount of water) for 4 hours to a clipped area of intact skin. Animals were then observed up to 72 hours post end of treatment. Irritation was scored using the primary irritation index grading scheme.
No clinical signs of toxicity or other lesions were observed. No erythema or oedema were evident at the dose site of any animal following exposure
Under the conditions of this study, the test material returned a PII of 0.0 and is therefore considered non-irritating.
