Irritation and sensitisation studies

14 skin studies and 5 eye studies are on record.

Classed as highly irritating5Classed as moderate3Classed as low32

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.
