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, decreasing to one ppm by April 1, 2027. For cosmetic products, the allowable concentration is set at ten ppm starting April 1, 2026, while personal care products will follow the same concentration limits as household cleaning products.

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 initial 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. The legislation aims to enhance public health and safety by limiting exposure to potentially harmful chemicals in everyday products.
