This bill aims to prohibit the sale of cosmetic and personal care products containing 1,4-dioxane, a hazardous substance and potential human carcinogen. The prohibition will take effect one year after the bill's enactment. The Commissioner of Environmental Protection is tasked with establishing allowable trace concentrations of 1,4-dioxane, which will be capped at 10 parts per million for cosmetic products and two parts per million for personal care products for the first two years, after which the limit will be reduced to one part per million. Additionally, the commissioner will review these standards within three years to determine if further reductions are necessary to protect human health and the environment.

Manufacturers may apply for a one-year waiver from these requirements if they can demonstrate efforts to reduce 1,4-dioxane in their products but are unable to comply. They may also apply for a second one-year waiver under similar conditions. The bill mandates the Department of Environmental Protection to adopt necessary rules and regulations to implement these provisions, aligning with similar legislation enacted in New York.
