“…Ammonium persulfate was added to the North American Contact Dermatitis Screening series in 2015, but is not included in the 2020 American Contact Dermatitis Society Core Allergen series, the TRUE Test, or the 2019 European Baseline Series. 4,5,7,14 In a recent series of more than 10 000 patients patch tested with the North American Contact Dermatitis Screening series from 2015 to 2018, 1.8% had a positive reaction to ammonium persulfate, with more than half of the reactions determined to be clinically significant. 8 Given the diverse use of persulfate compounds in common consumer products and the lack of persulfate compounds on commonly used patch testing series, it is likely that persulfate contact allergy is under-recognized.…”
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.
