Contact Allergy to Resorcinol Monobenzoate

Abstract

Resorcinol monobenzoate is an ultraviolet light absorber used in cellulose plastics and is known to cause allergic contact dermatitis reactions. It is the most important allergen in spectacle frames but can be a potential allergen in shoes as well. We report 7 cases of allergy to resorcinol monobenzoate with different clinical presentations. Our series further illustrates several possible cross-sensitizers.
