Irritation and sensitisation studies

4 skin studies and 2 eye studies are on record.

Classed as moderate1Classed as low2

The studies disagree (the most common conclusion covers 33%), 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.
