Persulfate-containing consumer products in the US market.

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.
