Contact eczema caused by textiles
Previously, textile-related contact eczema was mainly caused by urea-formaldehyde and melamine-formaldehyde resins used for crease-resistant finishing. Sensitization resulted from the formaldehyde released or from the entire resin molecule. Currently, cyclic urea derivatives are used for crease-resistant finishing, which rarely cause sensitization and release formaldehyde in smaller quantities. Among textile dyes, the most common sensitizers are azo dyes. A patient may be concomitantly sensitized to some of the para-amino compounds. In the case of group hypersensitivity, a patient sensitized to some of the para-amino compounds may respond by a contact allergic reaction to azo dyed textiles.
