Measure Protects Public Health and Environment by Reducing Harmful Emerging Contaminant in Cleaning, Personal Care, and Cosmetic Products
New York State Department of Environmental Conservation (DEC) Interim Commissioner Sean Mahar today announced the adoption of new regulations to reduce the presence of 1,4-dioxane in household cleansing, personal care, and cosmetic products. New York is the first state in the nation to adopt regulations that reduce 1,4-dioxane in these product categories to help protect consumers and natural resources and create healthier communities.
“Protecting the health and well-being of New Yorkers is paramount and science has shown that ongoing exposure to certain chemicals like 1,4-dioxane can harm public health and water quality,” Interim Commissioner Mahar said. “The regulations finalized today will enable DEC to fully implement the nation-leading law in place that helps prevent everyday household products from containing 1,4-dioxane for the benefit of the environment and our communities.”
1,4-Dioxane is a synthetic industrial chemical commonly associated with chlorinated solvents and was widely used as a chemical stabilizer in other formulations. It is also a byproduct or contaminant in consumer products such as laundry detergent and shampoo. 1,4-dioxane has been found in groundwater at sites throughout the U.S., particularly in Long Island’s sole source aquifer and in association with legacy industrial and hazardous waste sites. The toxicity and persistence of 1,4-dioxane in the environment represents a growing challenge because of the need for complex and costly treatment technologies to remove it from drinking water supplies.
Citizens Campaign for the Environment Executive Director Adrienne Esposito said, “This is a terrific success story and we are thrilled that New York’s law limiting 1,4-dioxane in consumer products is working and the NYSDEC’s newly adopted regulations further protects our drinking water and health from this hidden carcinogen. No longer are we washing our clothes, hair, bodies, and babies with high levels of this toxin. Manufactures have the ability to remove 1,4-dioxane from their products and the newly adopted regulations provide additional clarity ensuring products are in compliance with the law. CCE applauds the NYSDEC for advancing these regulations and in doing so protecting our families, drinking water and environment from 1,4-dioxane.”
The underlying New York State law requiring the reductions in 1,4-dioxane went into effect in December 2022. The regulations adopted today will bolster those efforts by defining the scope of covered products, establishing a standardized method of quantifying the 1,4-dioxane in covered products, and clarifying the process manufacturers must follow to receive waivers. These regulations also put the maximum allowable limits for 1,4-dioxane into regulation. Effective Dec. 31, 2022, the 1,4-dioxane limits for cosmetic products are 10 parts per million (ppm); effective Dec. 31, 2023, the limits for household cleansing and personal care products are 1 ppm.
DEC held a hearing to gather stakeholder input on the proposed rulemaking in February 2024, and accepted written comments and stakeholder feedback before finalizing the regulation. The final regulation and additional information are available on the DEC website.
