Applicant's summary and conclusion

Interpretation of results:
not irritating
Remarks:
Migrated information Criteria used for interpretation of results: EU
Conclusions:
The test substance is not irritating to the skin.
Executive summary:

In a GLP-compliant OECD guideline 404 study, rabbits were exposed to potassium tetrafluoroborate to determine skin irritating properties. 0.5 g of the test substance moistened with 0.5 mL distilled water were applied under semi-occlusive conditions to the skin of 3 rabbits for 4 hours. After the removal of the patches animals were observed for 72 hours. No evidence of skin irritation was noted (erythema and edema scores were 0 at all time points (24, 48 and 72 hours) in all animals). Based on the results of the study, potassium tetrafluoroborate is considered to be not irritating to skin.
