ACH

6/10

Concern level

Moderate concern

Volatile essential oil obtained from Achillea millefolium (yarrow). In cosmetics it is used primarily as a fragrance ingredient; yarrow-derived cosmetic ingredients, including yarrow oil, were reviewed by CIR and found safe in the present practices of use and concentration. The oil is a complex natural mixture rather than a single defined molecule, so physicochemical values such as molecular weight are not applicable.
