“…The best-known fragrance R-OOHs are those derived from limonene (limonene-OOHs), linalool (linalool-OOHs) and citronellol (citronellol-OOHs). 3,4 Hydroperoxides are believed to initiate the multistep process leading to skin sensitization through mechanisms involving radical intermediates. Potential formation of immunogenic complexes via radical intermediates has already been investigated for representative molecules.…”

“…This is particularly the case for hydroperoxides (R‐OOHs) derived from autoxidation of natural terpenes. The best‐known fragrance R‐OOHs are those derived from limonene (limonene‐OOHs), linalool (linalool‐OOHs) and citronellol (citronellol‐OOHs) 3,4 .

Background Essential oils (EOs) are widely used in cosmetics, perfumes, massage fluids, aroma therapy and natural medicine. Some EOs contain contact sensitizers. Objectives To describe the frequency of sensitization to EOs in dermatitis patients presenting in skin clinics including concomitant reactions, to evaluate the EO patch test preparations and to identify patient groups with an increased risk of EO sensitization. Patients and methods Retrospective analysis of data from the Information Network of Departments of Dermatology (IVDK), 2010–2019. Results Twelve EOs were patch tested in an aimed manner in 10 930 patients, of whom 908 (8.3%) reacted to at least 1 EO. Only 6 EOs elicited more than 1% positive patch test reactions: ylang ylang (I + II) oil (3.9%), lemongrass oil (2.6%), jasmine absolute (1.8%), sandalwood oil (1.8%), clove oil (1.6%) and neroli oil (1.1%). Concomitant reactions among EOs or to EOs and fragrances were frequent. Among EO‐positive patients, women, leg dermatitis patients, patients aged 40 years or more, masseurs and cosmeticians were over‐represented. Conclusions Sensitization to EOs occurs, albeit infrequently in most cases. Masseurs and cosmeticians have an increased risk of sensitization to EOs.
