Abstract
Background
Sensitization to acrylates is a concern in the occupational/environmental dermatology field.
Objective
To describe an occupational allergic contact dermatitis (ACD) outbreak from a smartphone screen protector glue.
Methods
Thirteen affected workers of a chain store selling phone screen protectors were investigated in five Spanish dermatology departments. The glue datasheet and label were assessed. A chemical analysis of the glue was performed. Based on this, some patients underwent additional testing.
Results
All patients (all female, mean age: 25) had severe fingertip dermatitis.
The datasheet/label indicated that the glue contained isobornyl acrylate (IBOA), a “photoinitiator” and polyurethane oligomer. The company informed us that the ingredients were polyurethane acrylate, “methacrylate” (unspecified), acrylic acid, hydroxyethyl methacrylate, propylmethoxy siloxane, and photoinitiator 184. Isobornyl acrylate (or IBOA) and N,N‐dimethylacrylamide (DMAA) were patch tested in eight and two cases, respectively, with negative results.
A chemical analysis revealed 4‐acryloylmorpholine (ACMO); isobornyl methacrylate (IBMA), and lauryl acrylate in one glue sample. Seven patients were patch tested with dilutions of the identified substances and six of seven were positive for ACMO 0.5% pet.
Conclusion
An outbreak of occupational ACD, likely from ACMO in a glue is described. Further investigations are needed to corroborate the role played by each compound identified in the chemical analyses.
