What are the most common irritants that cause contact dermatitis?

Metal and jewelry are common irritants, like nickel. Many people become allergic to their watches as the metal bands often contain nickel. With regard to contact dermatitis reactions from latex gloves, there are certain chemicals used in their manufacturing than can stimulate these allergic reactions. Among the more allergenic components are thiurams, antioxidants, and vulcanization accelerators. Remember, in the Type I latex sensitivity, a few of the natural rubber proteins cause allergic reaction, while Type IV, the offending agents are chemicals added to the latex in manufacturing.
