Repeated Exposure to Hydroperoxides of Linalool Induces Immunologically Verified Allergic Contact Dermatitis
Background: Fragrance allergens are a leading cause of contact allergy (CA). Linalool, common in cosmetics and household products, forms sensitising hydroperoxides (Lin-OOH) upon air exposure. Lin-OOH is linked to a high prevalence (3.9%–11.7%) of positive patch test results, but often gives rise to doubtful or irritant reactions. Objectives: To reassess patch test concentrations of Lin-OOH, deter
