The study sheds new light on possible environmental sources of this poorly understood water contaminant, called NDMA, which is of ongoing concern to health officials.

ABOUT 1,4-DIOXANE - 1,4-dioxane is generated as a byproduct of ethoxylation, a process used by some companies to provide mildness to harsh cleaning ingredients, which requires use of the cancer-causing petrochemical ethylene oxide. 1,4-dioxane is considered a chemical “known to the State of California to cause cancer” under Proposition 65, and is also suspected as a kidney toxicant, neurotoxicant and respiratory toxicant, among others, according to the California EPA.
