Interpretation of results:
not irritating
Remarks:
Migrated information Criteria used for interpretation of results: EU
Conclusions:
substance is not irritating
Executive summary:

In this study Wittigaldehydechloride was applied as such for 4 hours semi-occlusive to assess its primary skin irritation potential

on rabbits.

Experimental data reported indicate that the test article can be classified as not irritating for the rabbit skin.

No corrosive effect occurred on the treated skin of any animal at each measuring interval.
