“…For instance, “capsaicin hand dermatitis”, a form of irritant contact dermatitis, was described in the Hispanic population due to the prevalence of handling cayenne and jalapeno peppers barehanded as condiments in Hispanic dishes [ 51 , 52 ]. Furthermore, pizza makers may present with hand eczema, believed to be due to contact with ammonium persulphate (present in flour) and diallyl disulphide (found in garlic, a common pizza ingredient) during food preparation [ 53 ].…”

Hand eczema is a common disease with economic and social ramifications. This study undertakes a review of certain existing literature to provide insight into contributory factors which may result in the varying prevalence and severity of hand eczema among different ethnic groups, particularly to identify modifiable risk factors, as well as to ascertain knowledge gaps for future research direction. The existing literature suggests that factors including (a) genes, (b) differing skin physiology, (c) cultural practices, (d) dietary habits and associated food preparation, (e) climate, (f) predominant occupations, (g) socioeconomic factors, and (h) dissimilar laws and regulations may account for the disparity in the risk of hand eczema among different ethnicities. Given that endogenous factors cannot be avoided, but certain exogenous aspects can be modified, especially as the environment plays an important role in hand eczema flares, it is helpful from a practical perspective to focus on addressing the modifiable risk factors. These factors pertain to unique cultural practices, customs, and food preparation methods. Healthcare professionals should be well-acquainted with such factors to tailor the treatment approach for patients of different ethnicities accordingly because, with globalization, physicians face increasingly diverse patient populations such that cultural customs no longer remain limited to particular geographic regions.

“…The prevalence of persulfate flour allergy was high enough in bakers in those times that the use of persulfates as flour additives was banned by the European Union in 1957. More recently, occupational hand dermatitis has also been reported in pizza makers in Naples with contact to food additives containing ammonium persulfate 27 . Potassium and ammonium persulfate compounds are still approved as food additives at very low concentrations by the US Food and Drug Administration, but it is unclear how frequently they are currently used as food additives 9 .…”

“…More recently, occupational hand dermatitis has also been reported in pizza makers in Naples with contact to food additives containing ammonium persulfate. 27 Potassium and ammonium persulfate compounds are still approved as food additives at very low concentrations by the US Food and Drug Administration, but it is unclear how frequently they are currently used as food additives. 9 The use of persulfates as food additives is likely rare in the United States as we could not find an example product with local production after an extensive internet search, although we did find one brand of flour (Prima Unbleached Bread Flour, Prima Limited, Singapore) that contained potassium persulfate as a listed ingredient.…”

Background Persulfate compounds are reactive oxidative agents increasingly recognized as contact allergens. Objectives The aim of this study was to identify common consumer products containing persulfate compounds in the US market. Methods Five publicly accessible online ingredient repositories and searches of two large online retailers were used to identify persulfate‐containing consumer products. Results We identified persulfates in 23 hair colouring products, 11 denture cleansers, 8 pool/hot‐tub products, 3 paints, and 3 cleaning products. Conclusions Clinicians assessing contact dermatitis should be aware of three primary categories of consumer products that contain persulfates: denture cleansers, hair colouring products, and nonchlorine hot‐tub and pool shock.

“…Persulfates are a class of oxidizing agents used in various consumer and industrial products, including hair‐bleaching products, flour, industrial disinfectants, and pool‐shocking mixtures 2,3 . Persulfates may cause both immediate‐type reactions as well as allergic contact dermatitis (ACD) 2 .…”

Allergic contact dermatitis (ACD) is an important diagnosis to consider in patients with dermatitis following specific exposures. Classically, ACD from persulfates is associated with hair‐bleaching products and spa water/swimming pool exposure and is most commonly reported in adult men. We report a case of ACD to potassium peroxymonopersulfate (PPMS), a common pool “shocking” chemical, in a 7‐year‐old boy presenting with recurrent and diffuse dermatitis triggered by swimming pool exposure.
