Irritation and sensitisation studies
2 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.

- Not likely to be sensitizing
skin sensitisation: in vivo (non-LLNA) · Screening · equivalent or similar to OECD Guideline 406 (Skin Sensitisation) - Studies Indicate No Significant Irritation
skin irritation: in vivo · Screening · OECD Guideline 404 (Acute Dermal Irritation / Corrosion) according to - Ambiguous
