1,4-Dioxane Limits for Household Cleansing, Personal Care, and Cosmetic Products

pictures of various products containing 1,4-Dioxane
1,4-Dioxane limits are being established in a variety of products.

The Legislature recently enacted amendments to Environmental Conservation Law (ECL) Article 35 and Article 37 (links leave DEC's website) to establish limits on the amount of 1,4-dioxane that can be present in household cleansing, personal care, and cosmetic products sold or offered for sale in New York State. The law establishes a maximum allowable concentration of 2 ppm of 1,4 dioxane on December 31, 2022, and 1 ppm on December 31, 2023, for household cleansing and personal care products. The law also establishes maximum allowable concentration of 10 ppm of 1,4 dioxane on December 31, 2022, for cosmetics.

DEC is in the process of creating a rule to implement the law and is holding stakeholder meetings to seek input on the regulations.

Program Policy on Waiver Process

In 2019, the Legislature amended ECL Articles 35 and 37 to establish maximum concentrations of 1,4-dioxane in household cleansing, personal care and cosmetic products as of December 31, 2022. The law includes provisions to allow a manufacturer to apply for a one-year waiver from compliance, up to two times, based on the submission of proof to DEC that the manufacturer has taken steps to reduce the presence of 1,4-dioxane in their product or products and is still unable to comply with the statutory limits. The program policy may be found at the following link: DEC Program Policy (PDF, 310 KB).

Approved Waivers

After DEC reviews and issues an approval for a waiver application request, the following information will be made available: the name of the manufacturer, the product name, and the current amount of 1,4 Dioxane present in each product. This information is updated on a monthly basis and may be viewed at the following link:
