To check whether a product uses PFAS, identify the exact product and version, review its ingredient or materials disclosures, then ask the manufacturer whether PFAS are intentionally added to the product or any component. A “PFAS-free” label, a missing ingredient, or a total-fluorine test alone may not establish that no PFAS are present.
How do I know whether a product contains PFAS?
- Pin down the item. Note the exact model, shade or formulation, product version, and market where it is sold. Formulations and disclosure rules can vary.
- Check the available disclosures. Review the package, product page, ingredient list, and materials information. Search the manufacturer’s site for PFAS, chemical-management, or product-stewardship statements.
- Look for specific names as well as “PFAS.” For cosmetics, compare the ingredient list with the FDA’s examples below. For other product categories, an ingredient list may not be required or may not give a complete chemical inventory.
- Ask the manufacturer a specific question. Ask whether PFAS, including fluoropolymers, are intentionally added to the exact product or any of its components. If the company says “PFAS-free,” ask what substances and components the claim covers and what testing method or supplier documentation supports it.
- Assess the evidence and its limits. Distinguish a statement about intentional addition from a test for detectable substances. If uncertainty matters, ask a qualified laboratory which method is appropriate for the material and question.
- Check rules where you live. Requirements differ by jurisdiction and product category. Do not assume that one state’s labeling timetable applies nationally.
Which PFAS names should I look for?
The FDA lists these common PFAS ingredients found in cosmetics: PTFE, perfluorononyl dimethicone, trifluoroacetyl tripeptide-2, tetradecyl aminobutyroylvalylaminobutyric urea trifluoroacetate, perfluorohexylethyl triethoxysilane, methyl perfluorobutyl ether, and methyl perfluoroisobutyl ether. The list is a useful starting point for cosmetics, not an exhaustive list for all products. See the FDA’s information on PFAS in cosmetics.
Cosmetics are a category where FDA requires ingredient declarations, but a label’s silence is not proof that a product in any category is PFAS-free. Disclosure obligations vary, and many labels do not provide a complete chemical inventory. As one dated snapshot, the FDA reported that 51 PFAS were intentionally added across 1,744 U.S. cosmetic product formulations in product listing data as of August 30, 2024. Those counts describe that submitted data and cutoff date, not every cosmetic or the entire 2026 market. FDA’s 2025 Science Forum materials.
What is the difference between “no intentionally added PFAS” and “PFAS-free”?
“No intentionally added PFAS” describes a formulation or manufacturing-intent claim. It does not, by itself, say whether testing found trace contamination or what detection threshold was used. A claim that nothing is detectable by a specified test is different: its meaning depends on which substances and components were tested, the method, and its detection limits.

There is no single standardized meaning established here for every “PFAS-free” claim. Ask whether it applies to the full product or only selected materials, whether it covers components and packaging, and whether it concerns intentional use, trace presence, or both. The FTC’s Green Guides state: “It is deceptive to misrepresent, directly or by implication, that a product, package, or service is free of, or does not contain or use, a substance.” The rule concerns misleading claims; it does not make every “PFAS-free” statement automatically equivalent or prove a particular product’s composition. 16 CFR § 260.9.
Can a test tell me whether a product contains PFAS?
It may help, but the answer depends on the method and the material. Some analytical methods target particular PFAS; others provide screening evidence. A total-fluorine result is not, on its own, identification of PFAS or proof that PFAS are absent. FDA explains that total-fluorine analysis “only analyze[s] for fluorine in a product and cannot discern between the presence of PFAS or the presence of other non-concerning fluorine containing substances.” A detectable fluorine result therefore does not establish intentional PFAS use, and a result from a limited test cannot rule out substances the method does not cover.

If a decision requires stronger evidence than a label or company response, consult a qualified laboratory before testing. Explain the product material and the question you need answered, and ask which compounds the method can detect and what its detection limits are. Method selection and interpretation matter; no universal test result settles the question for every product. EPA’s overview of PFAS analytical methods and sampling research.
Do certifications or state labels prove a product is PFAS-free?
EPA Safer Choice
Safer Choice is a voluntary EPA program that reviews ingredients and other criteria, including product performance, pH, and packaging. EPA says PFAS no longer meet its Safer Choice Standard. The label indicates that a product meets the program’s criteria; it is not presented as a universal PFAS test certificate or a guarantee of absolute absence. The Safer Choice product directory can help locate listed products, but it is not a complete database of all PFAS-free goods. See EPA’s Safer Choice Standard and criteria and its comparison of Safer Choice and other programs.
State requirements
Rules are specific to place, product, and effective date. For example, New Mexico has adopted reporting and labeling requirements for covered products with intentionally added PFAS, with implementation dates beginning in 2027. That is not a nationwide disclosure mandate, and the covered-product rules should not be read as proof that all products without a label are PFAS-free. Consult the state’s PFAS information and rule materials for the applicable details.
