Despite marketing claims like “gentle” and “pure,” dozens of top-selling children’s bath products are contaminated with the cancer-causing chemicals formaldehyde and 1,4-dioxane, according to the March 2009 Campaign for Safe Cosmetics report, “No More Toxic Tub.”
This study is the first to document the widespread presence of both formaldehyde and 1,4-dioxane in bath products for children, including baby shampoos, bubble baths and baby lotions. Many products tested contained both chemicals.
Findings: The Campaign for Safe Cosmetics commissioned an independent laboratory to test 48 products for 1,4-dioxane; 28 of those products were also tested for formaldehyde. The lab found that:
-
17 of 28 products tested (61%) contained both formaldehyde and 1,4-dioxane.
-
23 of 28 products tested (82%) contained formaldehyde at levels ranging from 54 to 610 parts per million (ppm).
-
32 of 48 products tested (67%) contained 1,4-dioxane at levels ranging from 0.27 to 35 parts per million (ppm).
Where They Come From
The chemicals were not disclosed on product labels because they’re contaminants, not ingredients, and therefore are exempt from labeling laws. Formaldehyde contaminates personal care products when common preservatives release formaldehyde over time in the container. Common ingredients likely to contaminate products with formaldehyde include quaternium-15, DMDM hydantoin, imidazolidinyl urea and diazolidinyl urea. 1,4-dioxane is a byproduct of a chemical processing technique called ethoxylation, in which cosmetic ingredients are processed with ethylene oxide.
Manufacturers can easily remove the toxic byproduct, but are not required by law to do so. Common ingredients likely to be contaminated with 1,4-dioxane include PEG-100 stearate, sodium laureth sulfate, polyethylene and ceteareth-20.
