PFAS (per- and polyfluoroalkyl substances) are synthetic chemicals used in beauty products to repel water and oil. In makeup, they act like an invisible raincoat to create “all-day” staying power. They are called “forever chemicals” because they do not break down in the environment or the human body. However, as intentional PFAS are rapidly engineered out of cosmetics, the ultimate boundary for conscious beauty has shifted from the ingredient deck to the supply chain–specifically, the hidden reality of plastic container leaching.
Should You Worry About All Plastic Makeup Packaging?
No, you do not need to throw away every plastic tube. The plastics in your makeup bag–like a standard retractable plastic eyeliner or a lip gloss wand–are naturally stable and reportedly safe from leaching chemical PFAS.
According to investigations by the U.S. Environmental Protection Agency (EPA) and the Food and Drug Administration (FDA), the real culprit is a specific industrial process called fluorination. This process treats bulk High-Density Polyethylene (HDPE) and Polypropylene (PP) storage containers with fluorine gas.
While retail plastic containers do not leach chemicals, they can shed tiny, physical microplastic dust over time due to the friction of twisting a cap open and closed. Unlike dissolved chemicals, however, these physical plastic fragments are too large to pass through your skin cells and rinse off when you cleanse your face. These physical particles do however remain a long-term environmental concern once they are washed down the drain.
How “Forever Chemicals” Enter the Sourcing Pipeline
If the retail tubes on your vanity are safe, how do skincare and makeup formulas come into contact with these fluorinated industrial plastics? The contamination occurs almost entirely behind the scenes during the raw materials phase. Before a beauty brand mixes a final product, they must purchase bulk ingredients–such as botanical oils, raw fragrances, and active solvents–from global suppliers. To prevent volatile ingredients from evaporating or reacting with container walls during shipping, suppliers traditionally store them in heavy-duty, fluorinated HDPE or PP industrial drums.
Because the EPA confirmed that these treated drums leach PFAS into their contents in as little as one week, the raw ingredients absorb the forever chemicals before they ever reach the cosmetics manufacturer. Unless a brand explicitly mandates that their suppliers ship raw materials in inert glass or stainless steel, it seems the formula arrives at manufacturing already unintentionally contaminated.
Why PFAS (Forever Chemicals) Form a Known Health Concern
A landmark 2021 University of Notre Dame study screened over 200 cosmetics and found that a staggering 82% of waterproof mascaras and 63% of liquid foundations contained high levels of fluorine–the primary chemical marker for PFAS.
Medical research shows that PFAS readily absorb through the skin into the bloodstream. Once inside, they bioaccumulate and are linked to hormone disruption, thyroid disease, liver damage, and an increased risk of cancers.
The High-Risk Beauty Categories
If a product does not need to be waterproof or last for 24 hours, it rarely contains PFAS. But here are the high-risk categories:
- Waterproof Mascaras & Eyeliners: Engineered to resist perspiration, tears, and water.
- Liquid Foundations & Concealers: Formulated to resist facial oils for “24-hour” wear.
- Long-Wear & Liquid Lipsticks: Made to be completely transfer-proof through eating and drinking.
- Ultra-Durable Chemical Sunscreens: Formulated to stick to the skin.
- Aerosol Shaving Gels & Creams: Often use undisclosed synthetic polymers to help the razor glide.
PFAS-Free Future
When auditing your routine for forever chemicals, you don’t need to stress over complex cosmetic chemistry. The industry is rapidly shifting due to strict state bans and a recent FDA crackdown showing that less than 0.5% of cosmetics still intentionally use PFAS.
Hidden risks, however may still remain in your makeup bag:
- The Mass-Market Exception: Select legacy waterproof mascaras, budget liners, and 24-hour foundations still rely on intentional PFAS for extreme, industrial-grade staying power.
- The Packaging Loophole: Even if a formula is PFAS-free, PFAS can unintentionally leach into the makeup over time if raw ingredients were previously exposed to the fluorinated industrial storage drums detailed above. Intelligent brands bypass this supply-chain blind spot by utilizing stainless steel or inert glass packaging.
To verify your products independently, cross-reference with trusted consumer safety databases like the EWG Skin Deep Cosmetic Database and the clinical SkinSAFE Products Directory.
The following selection of brands maintain internal safety charters, align with strict global regulations, or partner with premium third-party verification directories to ensure their entire cosmetic, eye makeup, and cosmetic lines are 100% free of intentional PFAS and fluorinated polymers.

The Bottom Line: Intentional vs. Unintentional Purity
The takeaway for the beauty industry and consumers is a matter of distinguishing between what goes into the formula versus how it is stored. For decades, the presence of PFAS in makeup was intentional–deliberately added to waterproof mascaras and long-wear foundations for staying power. Today, as conscious beauty brands eliminate those targeted ingredients, the challenge has evolved into tackling unintentional contamination. A brand can formulate a completely clean formula, but if its raw ingredients spend weeks traveling inside a fluorinated industrial container, the invisible leaching process contaminates the final mixture before it ever reaches the factory.
Navigating the Noise: Putting Risk Into Perspective
It is easy to feel overwhelmed by constant headlines regarding “forever chemicals.” Context matters: unlike PFAS added for heavy waterproof wear, container leaching introduces microscopic trace amounts measured in parts per trillion. The FDA notes that these trace impurities present a low immediate safety concern under normal use conditions.
This is not to suggest the issue should be ignored, but the burden of solving it does not rest on the shopper. The industry is already fixing this blind spot behind the scenes. Proactive brands can mandate stainless steel or inert glass transit vessels and implement independent batch-testing to stop container leaching at the source.
