Prohibits sale of cosmetic products and personal care products containing 1,4-dioxane.

S 2946 bans the sale of cosmetic and personal care products containing 1,4-dioxane - a chemical linked to cancer - in New Jersey, affecting manufacturers and retailers of these items. It sets strict limits: 10 parts per million for cosmetics and 2 parts per million for personal care products (reducing to 1 ppm after two years), with trace amounts allowed only if approved by the environmental agency. Manufacturers can request a one-year waiver if they’re actively reducing 1,4-dioxane but can’t meet the limits immediately, with a possible second year. The environmental agency must review these limits after three years to assess if lower levels are needed for health protection.
