Fluorinated Plastic Containers
Moderate burden — Fluorinated Plastic Containers adds a moderate, reducible exposure.
Fluorine-treated HDPE bottles holding household and garden liquids.
The breakdown
Each driver rated 0 (none) to 10 (worst)
Evidence strength: moderate · Detox Score = 100 − hazard×4.6 − exposure×3.4 − persistence×2.6, clamped 1–100.
What this means for you
A Detox Score of 46 places fluorinated plastic containers in the Moderate band. The persistence rating is the standout concern here — these compounds linger in the body and environment for years. Treating a plastic bottle with fluorine to stop it leaking or swelling can form PFAS on the inner wall. EPA testing detected eight PFAS in rinsate from fluorinated HDPE containers at 20 to 50 parts per billion, and its September 2022 study found they leach into the liquid stored inside and keep leaching the longer it sits. The EPA says such containers are used for household consumer, pesticide, fuel and automotive products.
Frequently asked questions
Is fluorinated plastic containers a toxic exposure?
Fluorinated Plastic Containers has a Detox Score of 46 out of 100 (Moderate burden), which means it adds a moderate, reducible exposure. Treating a plastic bottle with fluorine to stop it leaking or swelling can form PFAS on the inner wall. EPA testing detected eight PFAS in rinsate from fluorinated HDPE containers at 20 to 50 parts per billion, and its September 2022 study found they leach into the liquid stored inside and keep leaching the longer it sits. The EPA says such containers are used for household consumer, pesticide, fuel and automotive products.
What is a safer alternative to fluorinated plastic containers?
A lower-exposure swap for fluorinated plastic containers is: The same product in an untreated container; ask the maker whether the bottle is fluorinated. Treating a plastic bottle with fluorine to stop it leaking or swelling can form PFAS on the inner wall.
