Stamatas and Tierney review diaper dermatitis. In the prevention discussion they describe two marketed zinc oxide ointments, one at 13 percent zinc oxide and one at 40 percent zinc oxide, applied at diaper changes. Zinc oxide is the active ingredient. The review does not measure lead, cadmium, or other impurity metals in the ointments. The brand name is omitted. The authors’ employer is a consumer-products company, which limits independence and is not a brand result.
Key numbers
Zinc oxide strengths as printed: 13 percent and 40 percent. No impurity-metal concentration is reported.
Methods (brief)
Narrative review, Pediatric Dermatology, 2014. The PDF file name carries 2013. The issue year is 2014.
Evidence fitness
The percentages support a statement about zinc oxide levels used in marketed diaper ointments in the cited comparison. They do not support an impurity-metal profile.
Limitations
Review, not an assay. Company affiliation. Clinical scores from the cited comparison are not re-extracted as metal data.
