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.

“…A recent study of Thai spa therapists showed a 45.5% prevalence of allergic contact dermatitis in suspected patients. The common allergens identified in that study were fragrance mix I (16.8%), MCI/MI (11.2%), and fragrance mix II (9.8%) 34 . Meanwhile, a study of occupational contact dermatitis among hairdressers and cosmetologists in North America revealed that glyceryl thioglycolate and PPD were the most common allergens, with contact with those allergens most commonly resulting from the use of permanent hair wave solutions, hair dyes, and tool/hair ornament sources 35 .…”

Changing trends of contact allergens: A 40‐year retrospective study from a referral centre in northern Taiwan

2021

Background The common contact allergens may change over time as the environmental exposure changes. Objectives To identify the prevalence rates and changing trends of contact allergens in Taiwan over a 40‐year period. Materials & Methods The patch testing results of a referral centre from 1978 to 2018 were retrospectively reviewed. The study population was divided into four groups according to 10‐year intervals. The prevalence rates of contact sensitization to each agent and the clinical relevance were analysed. For patients with positive reactions to relevant allergens, the occupations and sites of dermatitis were analysed. Results From 1978 to 2018, a total of 4005 patients underwent patch testing. Successively increasing trends of positive reactions to cobalt, fragrance mix I, and para‐phenylenediamine (PPD) were found. Methylchloroisothiazolinone/methylisothiazolinone (MCI/MI) was an emerging contact allergen. Hairdressers, cosmetologists, and aromatherapists became the occupations most commonly having positive reactions in the most recent 10 years. In the first two decades, the face and neck were the most commonly affected areas. Later, hands became the most commonly affected sites. Conclusions The prevalence rates of positive reactions to cobalt, fragrance mix I, and PPD increased successively. MCI/MI was an emerging contact allergen of special concern.

“…Neben chemisch definierten Einzelsubstanzen sind natürliche Extrakte in Form von ätherischen Ölen wichtige Allergene, wie in der oben genannten SCCS-Stellungnahme dargelegt wird, und ihre Verwendung ist weit verbreitet, z. B. bei 47 % der Befragten einer US-Convenience-Stichprobe von Besuchern eines State Fairs [94] oder bei thailändischen Luxus-Spa-Behandlern [95]. Ein aktuelles Ergebnis aus Australien weist darauf hin, welche Bedeutung Lavendelextrakte (in diesem Land) mit 2,2 % positiven Reaktionen auf verschiedene Lavendelextrakte haben [96].…”

Kontaktallergie (Sensibilisierung) und daraus resultierende allergische Kontaktdermatitis (ACD) sind von erheblicher Tragweite aus Sicht des Gesundheitswesens. Für die vorliegende Übersichtsarbeit hierzu wurden alle passenden Artikel aus dem Zeitraum 2018–2019 per systematischer Suche in Medline und Web of Science<sup>TM</sup> ermittelt; außerdem wurden alle verfügbaren Ausgaben der Fachzeitschriften „Contact Dermatitis“ und „Dermatitis“ manuell durchsucht und so eine frühere, ähnliche Übersichtsarbeit fortgeschrieben und neu fokussiert. Neue Allergene ebenso wie bekannte Allergene, die in neuem Expositionskontext gefunden wurden oder deren Bedeutung in sonstiger Hinsicht neu bewertet wurde, werden in Abschnitten nach Substanzklasse gegliedert beschrieben (z. B. Metalle, Konservierungsmittel, Duftstoffe). Als gemeinsames Ergebnis zahlreicher Untersuchungen fällt sowohl ein Mangel an Informationen über die Produktzusammensetzung auf, z. B. in Bezug auf ein neu beschriebenes Allergen in Leinenturnschuhen (Dimethylthiocarbamylbenzothiazolsulfid), als auch vor allem die mangelnde Kooperativität von Herstellern von Blutzuckermessgeräten bzw. Insulinpumpen. Zu den letztgenannten Geräten hat eine internationale Zusammenarbeit zwischen Dermatologen und Chemikern gezeigt, dass sie bei zahlreichen Diabetikern schwere ACD verursachen, indem sie Isobornylacrylat bzw. N,N’-Dimethylacrylamid freisetzen. Eine verbesserte und vollständige Deklaration der Inhaltsstoffe für Produkte alle Art – und nicht nur, wie wir es derzeit in Europa haben, bei Kosmetika (abgesehen von der vollständigen Auflistung der Duftstoffe) – muss auf die legislative Agenda gesetzt werden.
