Irritation and sensitisation studies
6 skin studies and 2 eye studies are on record.
The studies disagree (the most common conclusion covers 40%), so they do not establish that this ingredient is irritating. These tests are on the raw material itself; irritation at the amount in a finished product is a different question.
