Irritation and sensitisation studies
15 skin studies and 6 eye studies are on record.
The studies disagree (the most common conclusion covers 13%), 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.
