Irritation and sensitisation studies
3 skin studies and 1 eye studies are on record.
The study conclusions largely agree (100%). These tests are on the raw material itself; irritation at the amount in a finished product is a different question.
See all 4 studies
- Studies Indicate No Significant Irritation
