Cupcake Liners tested for indications of PFAS "forever chemicals"

Are you looking for safe cupcake liners without indications of PFAS “forever chemicals?” After we posted our investigation on non-toxic cupcake & muffin pans, many people asked us to come up with recommendations of cupcake liners. So we sent off the top 4 cupcake liners sold on Amazon and had them tested for indications of PFAS “forever chemicals.” You’ve trusted Mamavation to bring you topics like best air fryers sans PFAS “forever chemicals,” best non-toxic toasters, safest cookware, & best non-toxic dishes, now join us for the lab results of popular cupcake liners.

Disclosure: This post was medically reviewed by Sondra Strand, RN, BSN, PHN. Donations were provided by Environmental Health News and Mamavation community members. Mamavation has only “spot-checked” the industry and thus we cannot make predictions about brands and products that we have not tested. Products and manufacturing aides can change without notice so buyer beware. This post contains affiliate links, with some to Amazon, which means Mamavation will receive a portion of those sales and we will use that to pay ourselves back for the testing. You can also give a tax-deductible donation to our consumer studies here through Environmental Health Sciences. Click “yes” when asked if the gift is in honor of someone and type “Mamavation.” Thank you!

PFAS “Forever Chemicals” & Health Impacts

PFAS “forever chemicals” are per- and polyfluoroalkyl substances used as stain-resistant, water-resistant, & oil-resistant chemicals in commerce. They have been used for decades inside consumer products, manufacturing, and building materials. There are over 12,000 different chemicals in the PFAS chemical class (including PFOA & PTFE), and because there are so many of them, they are incredibly hard to identify and test for.

PFAS “forever chemicals” are problematic to human health and the environment. They are considered persistent, ubiquitous, and toxic, and therefore, it’s important you avoid them as much as you can to keep them from building up in our bodies. Many compounds can last for years in our bodies, therefore, it’s imperative to reduce the amount of PFAS you are exposed to from contaminated food and water.

Here are a list of health effects PFAS chemicals are linked to presently according to our scientific advisor and Former Director of the National Institute of Environmental Health Sciences and National Toxicology Program, Linda Birnbaum:

  • reduction in immunity
  • reduced vaccination response
  • increased risk of allergies & asthma in young children
  • affect the growth, learning, and behavior of infants and older children
  • increase cholesterol levels
  • metabolic diseases like obesity & diabetes
  • cardiovascular disease
  • lower a woman’s chance of getting pregnant
  • lowers male fertility
  • increase the risk of kidney & testicular cancers
  • Causes endocrine disruption
  • Disrupts normal thyroid function

Mamavation Finds Traces of PFAS “Forever Chemicals” In Other Adjacent Industries

PFAS, otherwise known as per- and polyfluoroalkyl substances (aka PFCs or perfluorinated chemicals, including PFOA and PFOS) are added to many products we purchase to make them “stain-resistant,” “grease-proof,” and “water-resistant.”

As we are writing this, Mamavation has finished 17 consumer studies looking for indications of PFAS inside everyday items and food we bring into our homes. In these studies, we have learned quite a bit about where PFAS chemicals hide in everyday products. Learn more about our other PFAS consumer studies here:

  • Period Underwear

  • Nut Butters (Peanut butter, etc.)

Mamavation’s Investigation on Cupcake Liners

Mamavation sent 4 cupcake liners purchased on Amazon off to an EPA-certified lab looking for indications of PFAS “forever chemicals.” The specific lab method used by Mamavation tested for total fluorine by using the Determination of Total Fluorine by Oxygen Flask Combustion and Ion-Selective Electrode. If detectable total fluorine was observed at a detection level of 10ppm, the lab did the Determination of free Fluoride Ion in the tablet by Ion-Selective Electrode and then subtracted that from the Total Fluorine to determine the amount of organic fluorine.

Organic fluorine testing is marker testing. There are over 12,000 different PFAS chemicals in commerce and it’s impossible to identify all of them. In fact, it’s only possible to identify about 100 or so in a really good commercial lab. Therefore, we do marker testing instead looking for the element they all have in common–organic fluorine. What else could organic fluorine possibly contain other than PFAS? Nothing you want to sip from. The other main possibilities are other fluoropolymers, pharmaceuticals, and common hydrofluorocarbon refrigerants, such as 1,1,1,2-tetrafluoroethane (commonly known as R-134a) and 2,3,3,3-tetrafluoropropene (commonly known as HFO-1234yf).

Not Our Favorite Cupcake Liners

Our lab found indications of PFAS “forever chemicals” inside the products listed here.

  • If You Care Jumbo Baking Cups — 12 parts per million (ppm) organic fluorine [updated 5/9/23]
  • Wilton Baking Cups — Assorted Colors/designs — 17 parts per million (ppm) organic fluorine

Best Cupcake Liners

Our lab did NOT find indications of PFAS “forever chemicals” inside the products listed here. The detection level of the test used at the lab was 10 parts per million (ppm).

  • Eoonfirst Standard Baking Cups Natural — non-detect organic fluorine
  • Gifbera Standard Baking Cups Natural — non-detect organic fluorine

    I agree with other comments it would be nice to offer something that is not from China. I do not purchase anything from China that comes in contact with my food.

    This does not offer many options, and it would be nice to have something that does not come from China, as I do not trust anything from there to not have some toxic parts to it. Also, I do not see the answer to the question about what makes both recommended brands “grease proof”?

    The packaging now says PFAS free. Did they change their product?

    I wonder if there are other non detectable PFAS in the recommended cupcake liners, as they both state they are grease-proof. Any advice or thoughts on this would be much appreciated. I would like to purchase some, but am hesitant because of the greaseproof aspect.

    What about paper liners? Are those safe or do they have a wax or spray coating that’s toxic?

    I cannot find your recommendation for muffin liners, could you please let me know what they are by listing them here. I have a very sensitive grandchild. Look forward to hearing from you. Thank you very much, Mrs. V

    If You Care cupcake liners surprised me, especially because they are marked as totally chlorine-free (TCF). I wonder what brings about the PFAS in their liners?

      Chlorine is usually applied for bleaching and flouride is associated with the non stick properties of PFAS

    It looks like Mamavation does recommend the If You Care Parchment Paper: https://mamavation.com/food/safest-non-toxic-parchment-paper-without-pfas-forever-chemicals.html

    Thank goodness because I’ve been using that for years!

    Strange that the If You Care Cupcake liners aren’t good, too.

      If You Care parchment paper is NOT safe, just because it doesn’t have PFAS doesn’t mean it’s healthy. It has a silicone coating and any coating, including silicone is not safe to cook food in, it is actually toxic. It’s also not compostable.

      There’s only one coating-free parchment paper brand I have found and that is Baar.
      The Healthy Home Economist links to it in her article on why all parchment paper is toxic.

      The simple thing to do and the least wasteful and only non-toxic option is to just GREASE the pan!

      They are there in the “not our favorites” section. Very disappointed because that’s what I have been using thinking they were safe.
