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

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.

Outreach Information

DEC held two virtual public meetings to present and discuss the topics related to the law and regulations that may be developed. During the first meeting on November 18, 2020, DEC presented topics for discussion, which included the scope of covered products and the waiver process. A recording (link leaves DEC website) of the first meeting and slides (PDF, 679 KB) are available for review. The second virtual public meeting was held on December 2, 2020 and was a discussion of the information presented during the first meeting.

When regulations are proposed, they will be available for public comment.

Draft Program Policy on Waiver Process

The maximum concentrations of 1,4-dioxane in household cleansing, personal care and cosmetic products enacted in ECL Article 35 and Article 37 include a provision that allows manufacturers to apply for a one year waiver from compliance, up to two times. DEC has published a draft Program Policy to provide clarification on the proof DEC will require to grant such waiver as well as the process for manufacturers to submit and implement the waiver request.

Written public comments may be submitted via email to or via mail to the address below until May 7, 2021 at 5:00 p.m.
