Occupational asthma reported in workers manufacturing solder flux and rubber tires; [Malo] Allergic contact dermatitis in construction workers, house painters, shoemakers, electronics workers, machinists, and mechanics; [Marks] Colophony was thought to be the allergen in a case of occupational rhinitis caused by Nobetec, used by dentists to make temporary dental fillings.

| Comments |
Gum rosin, the most common type of colophony, is derived from living pine trees. Wood rosin and tall oil rosin are other types of colophony. Abietic acid is the active allergen present in colophony. [Marks, p. 80] Other allergens found in soldering fluxes include aminoethylethanolamine and hydrazine. Aminoethylethanolamine-based solders are commonly used in printed circuit board soldering. [Marks, p. 318] Skin sensitization to colophony allergens is common. It is not possible to patch test for all of the allergens in colophony. Since colophony allergens are present in many products at work and at home, it may be difficult to avoid exposure. [Kanerva, p. 509-16] |
