Does My Cleaning Product Have PFAS?

What is PFAS, and why does it show up in cleaning products at all?

PFAS stands for per- and polyfluoroalkyl substances — a large family of synthetic chemicals built around carbon-fluorine bonds, which happen to be one of the strongest bonds in organic chemistry. That bond strength is exactly why chemists reached for PFAS in the first place: it makes a coating that resists water, oil, and stains almost indefinitely, and it barely breaks down over time. It's also why PFAS earned the nickname "forever chemicals."

Most people first hear about PFAS in the context of non-stick cookware or waterproof jackets, not spray bottles. In cleaning products specifically, PFAS tends to show up for a narrower set of reasons:

• Waterproofing and anti-stain agents. Some stone, tile, and grout sealants and stain-guard sprays use fluorinated compounds to repel water and oil after application.
• Fluoro-surfactants. A small number of industrial-strength degreasers and specialty cleaners use fluorinated surfactants because they lower surface tension exceptionally well, letting the product spread into tight grease or grime.
• Carpet and upholstery protectants. Some fabric and carpet treatments marketed to resist spills use PFAS-based coatings.

The micro-lesson here: PFAS is not a routine ingredient in everyday multi-surface sprays, dish soap, or glass cleaner. It clusters in a specific job — making a surface repel liquid — which is why it’s worth checking labels on waterproofing, stain-guard, and heavy-duty degreasing products more than your basic all-purpose spray.

Connecticut’s new PFAS labeling law: what it actually says

Here is the plain, verifiable text. Connecticut Public Act 24-59 (Substitute Senate Bill 292, “An Act Concerning the Use of PFAS in Certain Products”) states that “on and after July 1, 2026, no person shall manufacture, sell, offer for sale or distribute for sale in this state any (A) apparel; (B) carpet or rug; (C) cleaning product; (D) cookware; (E) cosmetic product; (F) dental floss; (G) fabric treatment; (H) children’s product; (I) menstruation product; (J) textile furnishing; (K) ski wax; or (L) upholstered furniture if such product contains intentionally added PFAS, unless the manufacturer of the product provides prior notification in writing to the department.” The act defines “cleaning product” broadly, as “a finished product used primarily for domestic, commercial or institutional cleaning purposes,” including air care products, automotive maintenance products, general cleaning products and polishes or floor maintenance products.

So it is a conditional sales restriction with a notification off-ramp, not a warning-label rule. We want to be exact about that, because we have seen it described both ways online and the difference matters if you are trying to figure out what will actually change on a Connecticut shelf.

A few things worth being precise about, because it’s easy to overstate a story like this:

• It’s state law, not federal law. This requirement applies to products sold in Connecticut. It is not a nationwide FDA or EPA mandate, and we won’t claim otherwise.
• It’s a labeling requirement, not necessarily a nationwide reformulation. Manufacturers selling into Connecticut now have to disclose intentionally added PFAS on the label for covered products. Whether a given brand reformulates everywhere or just labels what it sells into that state is a business decision that varies by company.
• Connecticut isn’t alone in looking at PFAS. Several states have been moving on PFAS in consumer products in recent years, though the specifics — what’s covered, what’s required, and when it takes effect — differ by state. We’re not going to guess at another state’s law here; if you want to know what applies where you live, check your own state’s current regulations directly.

The truth most coverage skips: a labeling law is a genuinely useful step — it turns an invisible ingredient into something you can actually see on the shelf — but it’s also a reminder that this kind of transparency has, until now, been optional almost everywhere. One state deciding to require a label is newsworthy precisely because it’s still the exception, not the rule.

How to check if a product you already own might contain PFAS

You don’t need a lab to start. Pull the bottle, find the ingredient list or safety data sheet, and scan for this language — the same label-reading skill that helps you catch quats in disinfectant sprays or hidden fragrance chemicals anywhere else under your sink:

A few practical notes on doing this check yourself:

• Everyday multi-surface cleaners, dish soap, and glass cleaner rarely need this check. PFAS clusters in waterproofing and stain-resistance products, so start with anything in your cabinet marketed as a sealant, stain-guard, or heavy-duty degreaser.
• US cleaning labels don’t always require full ingredient disclosure. If the bottle doesn’t list ingredients at all, look up the product’s safety data sheet (SDS) online, which manufacturers are required to make available and which lists active and hazardous components in more detail than the retail label.
• “Non-stick,” “stain-resistant,” and “water-repellent” are marketing claims, not proof. Some brands achieve these effects without PFAS. The only way to know for a specific product is to read the actual ingredient or SDS language, not the front-of-bottle promise.
• When in doubt, contact the manufacturer. Reputable brands will tell you directly whether a product contains PFAS if you ask.

Why this is worth paying attention to, without the alarm

Here’s the calibration that matters: this is genuinely new and worth knowing about, and it is not a reason to panic about your cleaning cabinet. Most everyday cleaning products — the multi-surface spray, the dish soap, the glass cleaner — were never built with PFAS chemistry in the first place, because they don’t need a water-repelling coating to do their job. The category where PFAS actually clusters is narrower: sealants, stain-guards, and a handful of specialty degreasers built specifically to resist liquid.

What Connecticut’s law reflects is a broader, slower shift: state governments and independent researchers taking a harder look at where PFAS ended up over the past few decades, largely because these compounds don’t break down easily once they’re in the environment or the body. A visible label is a small, concrete step toward letting a shopper actually see what’s in the bottle before it goes in the cart — which is the same principle we build every Ecolosophy formula around, regardless of what any single state requires, and the same standard worth applying to everything else in your all-purpose cleaner.

It’s not just state product laws moving, either: EPA has set national drinking-water regulation for several PFAS compounds (EPA, PFAS in drinking water), which reflects how far regulation has shifted from “emerging concern” to “actively regulated.” That federal move is a useful data point for judging how seriously to take PFAS generally — while being honest that drinking water and a stain-guard spray are two different exposure routes, and a drinking-water standard says nothing about what is in your all-purpose cleaner.

How PFAS builds up in household dust — and in you

The exposure path isn’t just spraying a product directly. A 2022 review led by Yale researchers in Current Environmental Health Reports describes PFAS as “a family of more than 7,000 fluorinated compounds” and notes that “various household products can release volatile and nonvolatile PFAS into the indoor environment that often concentrate in dust,” with daycares and workplaces highlighted “as locations with widespread exposure due to the presence of treated carpeting and industrial-strength cleaners” (Pollitt et al., PMID 34985714). We’ve seen specific detection percentages attached to this paper elsewhere; it is a review of the literature rather than a single dust survey, so we’re not going to print numbers it doesn’t report. The mechanism is the point: what gets sprayed indoors ends up in settled dust, and small children spend their day at floor level.

A 2025 case-control study in the International Journal of Cancer measured PFAS in settled house dust and found that a mixture of eight PFAS was associated with an elevated risk of childhood acute lymphoblastic leukemia (odds ratio 1.60, 95% CI 1.15–2.24), with one compound, EtFOSAA, carrying the strongest individual association (PMID 39950710). Read that carefully with us: it is an association in a case-control design, it concerns PFAS measured in dust rather than any named product, and one of its authors discloses serving as a paid expert witness in PFOA litigation. It is a real, peer-reviewed signal — and it is not evidence that any cleaning product causes leukemia. We will not make that leap and neither should anyone quoting this page.

What is not in dispute is persistence. A Yale-led review describes PFAS as “a family of more than 7,000 fluorinated compounds” whose carbon-fluorine bond “prevents appreciable degradation once released into the environment” (PMID 34985714). That durability — not any single acute exposure — is the reason a law like Connecticut’s exists.

The Ecolosophy story: why full disclosure isn’t optional here

“I spent 23+ years fighting Crohn’s disease, and somewhere in that fight I learned to stop trusting a label that only tells you part of the story. That’s the whole reason Ecolosophy exists — not to wait for a state to require disclosure, but to already be disclosing everything. Plant-based, no PFAS, no synthetic fragrance, small-batch and made with care. When a law like Connecticut’s passes, our answer to ‘does your product have this?’ doesn’t change, because it was already no.”

Ecolosophy’s All-Purpose Cleaning Concentrate is formulated without PFAS, without quats, and without synthetic fragrance. One bottle makes 100+ ready-to-use spray bottles, so you’re replacing the stain-guards, degreasers, and multi-surface sprays that might carry fluorinated chemistry with a single, fully disclosed concentrate for daily cleaning.
