Non-occupational epoxy resin allergy

Background

Sensitization to epoxy resin is mostly acquired occupationally, with those employed in the construction industry being particularly affected. Cases of non-occupational epoxy resin allergy are observed less frequently. In the literature, an association between epoxy resin allergy and fragrance allergy is postulated.

Methods

Analysis of corresponding data from the Information Network of Departments of Dermatology (IVDK); literature review.

Results

In the IVDK 2013–2022, the rate of positive reactions to epoxy resin in patients with occupational dermatitis (OD) was 2.4–4.0%, in patients without OD 0.8–1.5%. Accompanying reactions to reactive diluents and hardeners prove an exposure to epoxy resins also in patients without OD. Patients sensitized to epoxy resin have an increased risk of reactions to other baseline series allergens. Case reports of non-occupational epoxy resin allergy concern work with casting resins. However, epoxy resin exposure is also possible, for example, from three-dimensional (3D) printing finishes or products for hoof repair in horses.

Discussion

Non-occupational epoxy resin allergy may be acquired not only from do-it-yourself activities in the narrow sense, which should be considered when taking the medical history. The association between epoxy resin and fragrance allergy does not go beyond the general level of associations between contact allergies with each other.
