The proposed legislation, Substitute Bill No. 884, aims to regulate the concentration of 1,4-dioxane in household cleaning products, personal care products, and cosmetics. Effective October 1, 2025, the bill stipulates that starting April 1, 2026, household cleaning products must not contain more than two parts per million (ppm) of 1,4-dioxane, reducing to one ppm by April 1, 2027. For cosmetic products, the allowable concentration is set at ten ppm starting April 1, 2026. Personal care products will follow a similar regulation as household cleaning products, with a limit of two ppm starting April 1, 2026, and one ppm by April 1, 2027.

Violations of these regulations will result in fines imposed by the Commissioner of Energy and Environmental Protection, with penalties of up to one thousand dollars per day for first-time violations and up to two thousand five hundred dollars for subsequent violations. The bill also defines "cosmetic product" and "personal care product," clarifying that these do not include items requiring a prescription for distribution. Overall, the legislation seeks to protect public health by limiting exposure to potentially harmful chemicals in everyday products.
