Does Colgate Toothpaste Have Microplastics? Check the Exact Formula
Colgate says it stopped microbeads in 2014, and the Total formula reviewed has no obvious solid microplastic. The exact regional paste and the multilayer HDPE tube still need separate checks.

Are Nylon Cooking Utensils Plastic? Yes—Heat Is the Real Test
Nylon is polyamide plastic. Studies from 2016–2026 measured oligomers and aromatic amines rather than one universal particle count; heat, contact time and visible damage decide the practical response.

Is Polyester Plastic? Yes—Here Is When Clothing Sheds Most
Polyester is usually PET plastic in fibre form. Real-laundry studies show how construction, high-water cycles, load size, temperature, drying and partial-capture devices change shedding.

Does Parchment Paper Have Plastic? Silicone Is the Key Detail
Most parchment is cellulose paper coated with cured silicone, not polyethylene film. The direct shedding evidence is limited, and plastic-coated freezer paper is a different product entirely.

Does Evian Have Microplastics? What Two Tested Lots Found
Two Evian lots averaged about 197 and 58 particles per litre under the 2018 method. The exact lot table, detection limits, current recycled-PET packaging and practical format alternatives.

The Lake Did Not Get 656 Times Dirtier. The Test Finally Looked Smaller.
A new Lake Geneva method found that up to 97% of estimated particles sit between 1 and 20 micrometres. The 226–656× jump over older surveys is a change in what the test can see—not a sudden change in the lake.

The Steel Ball Changes What a Plastic Shaker Bottle Releases
The first direct shaker-bottle study tested polypropylene, polycarbonate and Tritan. Every bottle shed; the steel ball increased abrasion; and the annual estimate is simultaneously 74,000–146,000 particles and only 42–72 micrograms of mass.

The Cup Noodle Study Everyone Cites Never Counted the Particles
Instant noodle containers have one government safety assessment — Hong Kong, 2009 — and it cleared them on chemistry: styrene, heavy metals and total migration all inside the limits. It never counted particles, and nobody has since. Meanwhile the one fix that halves release in disposable cups, rinsing before use, is impossible when the food is already in the cup.

The Slow Cooker Liner Is Not a Sandwich Bag
Liners are nylon rated to 400 °F, not polyethylene — the film is nowhere near its limit in a crock. But nylon 6 is made from caprolactam and nylon 66 is not, the manufacturer says only “a blend of nylon”, and that omission decides which migration question applies to dinner.

The Bamboo Plate Is Melamine in 20 Cases Out of 21
A 2025 Food Control analysis detected melamine in 20 of 21 food-contact articles sold as bamboo — and the EU never authorised bamboo flour in plastics at all, because bamboo is a grass and the wood-flour clearance does not reach it. The label is not a test you can run.

The Recycled Bottle Is the More Contaminated One
A Brunel evidence map traced 193 food-contact chemicals across the PET bottle lifecycle and found 150 documented migrating — with higher reported migration of antimony and BPA from recycled PET than virgin. Not an argument against recycling; an argument that “100% recycled” is a claim about waste, not about your drink.

Do Toothbrush Bristles Shed Microplastics? Study Review
A 2025 simulation found toothbrush particle release but did not measure swallowed dose. Here is what the annualized estimate, polymer results and dental guidance actually support.

The PFAS Left Microwave Popcorn Bags. The Plastic Film Did Not.
US manufacturers stopped selling grease-proofing PFAS for food packaging in February 2024, so the warning most articles still repeat is out of date — and the study everyone quotes runs on data from 2003–2014. But every bag still holds a metallized PET susceptor film that reaches about 450°F against the food.

Blending Ice for 30 Seconds Released Hundreds of Millions of Plastic Particles
Thirty seconds of blending ice in a plastic jar released an estimated 0.36–0.78 billion micro- and nanoplastic particles. The mechanism is abrasion, not heat — which is why "BPA-free" and "Tritan" do not answer the question, and why the fixes are mechanical and mostly free.

Clear Aligners Shed Microplastics — and the BPA Comes From Somewhere Else
Seven aligner brands shed microplastics into artificial saliva over seven days, most particles 5–20 µm — and Invisalign released the fewest, not the most. The BPA spike measured in patients came 30 minutes after the composite attachments were bonded, not from the tray, and was back to baseline within a week.

The EPA Just Listed Microplastics — and Declined to Measure Them
On 6 April 2026 the EPA put microplastics on its draft Contaminant Candidate List for the first time in the list’s 30-year history. Three months later it left them out of UCMR 6, the rule that would actually require water systems to test for them. Both are true, and almost nobody reported them together.

PFAS in Cooking Oil: When the Plastic Doesn't Come From the Bottle
A third-party test found PTFE — a fluoropolymer, and therefore a PFAS — suspended in an olive oil whose squeeze bottle is not made of PTFE. That mismatch points upstream at processing equipment rather than packaging. Plus the regulatory science on why fat extracts more from plastic than any other food.

We Scored 132 Products for Microplastics. Only 12 Have Ever Been Measured.
An audit of our own database. Nine percent of our product scores rest on a measurement of that exact item; 53% are reasoned from materials and use conditions. Six categories — 56 products — contain no measured item at all. And the measured products score 22 points worse, which turns out to say more about what science chooses to study than about the products.

Is Owala Non-Toxic? The Body Is Fine — the Answer Is in the Lid
The insulated body is stainless steel and inert, and the BPA-free claim is genuine rather than a BPS substitution. The microplastics question lives in the plastic lid, spout and straw. Owala does not say which parts are Tritan, and no one has published a particle test of an Owala lid.

Is It Plastic? Every Material in Your Kitchen, Answered
Nineteen of the thirty materials in an ordinary kitchen are plastic, and most people can name about six. Polyester and nylon are plastic. Melamine is plastic. PLA is plastic despite the compostable label. Silicone is not, quite — it is a siloxane. And "bamboo fibre" tableware is usually melamine resin with a plant filler.

Think Dirty vs Yuka: How the Two Scanners Differ — and the Question Neither One Asks
Yuka scores 0–100 off its single worst ingredient; Think Dirty scores 0–10 and leans natural. Yuka carries ~2M products against Think Dirty’s ~1,200 brands. But neither rates synthetic polymers, because inert plastics are invisible to toxicological hazard criteria by design — so a formula can score well on both and still be built out of plastic.

Microplastic Testing: What a Lab Can Actually Measure — and Why "None Detected" Isn't Clean
Micro-FTIR stops seeing particles around 10 micrometres and micro-Raman around 0.5. Much of the research linking microplastics to human tissue sits below both limits — so a clean water result is a statement about the instrument, not about your water. What labs measure, what mail-in kits deliver, and the test that does not exist at any price.

Nail Dust Is Microplastic — and Nail Polish Has a Legal Exemption Until 2035
Acrylic is the most common polymer in nail salon air — 27% of particles, at an estimated 67,567 inhaled a year. And under the EU microplastics restriction, nail products got the longest transition of any category: 17 October 2035, with a "This product contains microplastics" label required from 2031.

Do Contact Lenses Shed Microplastics? The 2026 Study Points at the Blister Pack
A June 2026 study analysed the whole routine — new lenses, worn lenses, blister packs, cases and solutions — and found microparticles in every sample type. Then the polymer fingerprints said most of them did not come from the lens. The part you cannot change turns out not to be the part that matters most.
