Air-oxidized linalool: a frequent…nce contact allergy.

Findings

About 7% of people with dermatitis had allergic reactions to oxidized linalool, a breakdown product of linalool (a common fragrance ingredient). The study found that while pure linalool is safe, it oxidizes when exposed to air, and those oxidized byproducts are what actually trigger allergies—meaning your fragrance exposure matters as much as the ingredient itself.
