Irritation and sensitisation studies

5 skin studies and 2 eye studies are on record.

Classed as highly irritating6Classed as moderate2Classed as low8

The studies disagree (the most common conclusion covers 38%), 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.
