1,4-Dioxane:Insight and Compliance Strategies for Manufacturers Facing New Limits

1,4-Dioxane is a manufacturing byproduct that can be a trace contaminant in a wide range of consumer products, particularly those containing ethoxylated surfactants. These surfactants—commonly used to enhance foaming, improve cleansing efficiency, and modify viscosity—are found in personal care and household cleaning formulations, including shampoos, body washes, dish detergents, and laundry detergents.

In the United States, regulation of 1,4-dioxane in consumer goods is limited at the federal level, though several states have taken independent action. In December 2019, New York passed legislation limiting 1,4-dioxane concentrations to below 1 ppm in household cleaning and personal care items and to 10 ppm in cosmetics, with enforcement beginning after December 31, 2023. California, which lists 1,4-dioxane under Proposition 65, requires warning labels on products that expose consumers to levels above the established safe threshold.
