Allergen of the Year is an annual "award" voted upon by the American Contact Dermatitis Society, aiming to raise awareness about common allergens. The purpose of the award is "to draw attention to the agents causing the most significant clinical effects, those that are underrecognized and those that have become obsolete or for which exposure patterns have changed".
Contact dermatitis is a type of acute or chronic inflammation of the skin caused by exposure to chemical or physical agents. [1] Symptoms of contact dermatitis can include itchy or dry skin, a red rash, bumps, blisters, or swelling. These rashes are not contagious or life-threatening, but can be very uncomfortable.

The American Contact Dermatitis Society named methylisothiazolinone "contact allergen of the year" in 2013. [10] The North American Contact Dermatitis Group found that methylisothiazolinone caused 10.9% positive reactions, being the third most common contact allergen in patch test results which surveyed close to 5000 contact dermatitis patients ...
A patch test relies on the principle of a type IV hypersensitivity reaction.. The first step in becoming allergic is sensitization. When skin is exposed to an allergen, the antigen-presenting cells (APCs) – also known as Langerhans cell or Dermal Dendritic Cell – phagocytize the substance, break it down to smaller components and present them on their surface bound major histocompatibility ...
The American Academy of Allergy, Asthma, and Immunology (AAAAI) dates back to the 1920s through the founding of two professional organizations: The Society for the Study of Asthma and Allied Conditions and the American Association for the Study of Allergy. [5] In 1943, the two organizations united to create the American Academy of Allergy (AAA).
Quaternium-15 is an allergen, and can cause dermatitis. [6] Many of those with an allergy to quaternium-15 are also allergic to formaldehyde. At low pHs, it would be expected to release significant amounts of formaldehyde due to acid hydrolysis via the Delepine reaction. Allergic sensitivity to quaternium-15 can be detected using a patch test. [7]
Allergic contact dermatitis (ACD) is a form of contact dermatitis that is the manifestation of an allergic response caused by contact with a substance; the other type being irritant contact dermatitis (ICD). Although less common than ICD, ACD is accepted to be the most prevalent form of immunotoxicity found in humans. [1]
