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

the primary skin irritation of a 0,01% solution of the test substance on the clipped belly of albino rabbits on a 24h exposure period was tested on each of 5 rabbits. The result score of 1 out of a scale of 10 corresponds to no irritation having been observed under test conditions.
