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

The Legislature recently enacted amendments to Environmental Conservation Law (ECL) Articles 35 and 37 (link leaves 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.
