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 2 parts per million for personal care products for the first two years, after which the limit for personal care products will be reduced to 1 part per million.

Additionally, the bill allows manufacturers to 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. A manufacturer may apply for one additional waiver under similar conditions. The Department of Environmental Protection will adopt necessary rules and regulations to implement the act, which is modeled after similar legislation in New York.
