1,4-Dioxane
Not used — health & safety concerns
1,4-Dioxane is a synthetic carcinogen that appears as an unintentional contaminant in cleaning and personal care products using ethoxylated surfactants — including sodium laureth sulfate (SLES) and many polyethylene glycols. Because it is a manufacturing byproduct rather than an added ingredient, it does not appear on labels. This page covers what 1,4-dioxane is, how it forms, regulatory action, and how NFP's surfactant choices avoid it.
