Preservatives are common ingredients indicated in allergic contact dermatitis (ACD). Health care practitioners should familiarize themselves with those most frequently used in cosmetics, drugs, and occupational exposure so that they can provide adequate care and education to affected patients. This chapter summarizes the preservatives used in the Standard Series Patch Test, which are also common causes of ACD. We also provide two case examples of ACD resulting from contact with the above additives.
