Irritation and sensitisation studies
4 skin studies and 4 eye studies are on record.
Classed as highly irritating1Classed as low4
The studies disagree (the most common conclusion covers 20%), 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.
