What Customers Say After the Switch
From greenwash-burned shoppers to allergy households — here's what changed when they swapped in Sampson.
Old top-loader with an agitator and a busy house. This is the first plant-based detergent that actually sudses up and cleans like my machine expects. Whites stayed white through a winter of hockey gear.
Switched the whole house off mainstream detergent. Read the ingredient list and recognized everything — they even tell you straight that the LAS is petroleum-based. That honesty is why I trust the rest.
My son's eczema flared with our old detergent. Unscented, no brighteners, no quats. A few loads in and his skin settled. I add a couple drops of lavender oil to the sheets and that's it.
Cleans well and I like the standard formula for my agitator washer. Took me a couple loads to realize I only needed the HE one for the front-loader downstairs — would help if the bottle label made the standard-vs-HE choice clearer up front.
Why most "eco" laundry detergent isn't
The phosphate cap was 5%. Now it's 0.5%. The rest of the formula didn't change.
Canadian regulation reduced phosphate content in laundry detergent in 2010. The petroleum surfactants, the "fragrance" loophole that hides phthalates, and the residue that runs into your local watershed weren't part of that rule.
Indoor VOC concentrations run 2–5× higher than outdoor — up to 10× during and after cleaning (EPA TEAM Study)
Phthalate metabolites are detectable in nearly all people tested in national biomonitoring — and synthetic "fragrance" in cleaning products is a recognized exposure route that needs no ingredient disclosure (CDC NHANES)
About 60% of the surfactants produced globally each year end up in aquatic environments — half of all consumption is household use (Arora 2022 (Wiley))

We Spent 30+ Years Cleaning Up Contamination. Then We Checked Under the Sink. Nous avons passé 30+ ans à décontaminer des sites. Puis nous avons regardé sous l'évier.
Diana Trasente and Angelo Diadelfo are environmental engineers with Master's degrees and over 30 years remediating contaminated soil and water across Canada. They know industrial chemicals intimately — PCBs, heavy metals, synthetic surfactants, petroleum solvents. Diana Trasente et Angelo Diadelfo sont des ingénieurs en environnement avec des maîtrises et plus de 30 ans d'expérience en décontamination de sols et d'eau au Canada.
Then they started reading the labels on their own household cleaners. The same classes of synthetic chemicals they spent their careers cleaning up were sitting in their kitchen, bathroom, and laundry room. Puis ils ont commencé à lire les étiquettes des nettoyants ménagers chez eux. Les mêmes classes de produits chimiques qu'ils passaient leur carrière à nettoyer se trouvaient dans leur cuisine, salle de bain et buanderie.
In 2010, they founded Sampson Eco Shop — applying the same scientific rigor to household cleaners that they applied to environmental remediation. Every product starts with one question: What's actually in here, and is it safe to put down a drain? En 2010, ils ont fondé Sampson Eco Shop — appliquant la même rigueur scientifique aux nettoyants ménagers qu'à la décontamination. Chaque produit commence par une question: Qu'est-ce qu'il y a vraiment dedans, et est-ce sécuritaire de l'envoyer dans un drain?
“Every cleaner we make starts with the same question we'd ask on a contamination site: what's actually in here, and what happens when it goes down the drain?” “Chaque nettoyant qu'on fabrique commence par la même question qu'on poserait sur un site contaminé: qu'est-ce qu'il y a vraiment dedans, et qu'est-ce qui se passe quand ça va dans le drain?”— Diana Trasente, M.Eng. — Diana Trasente, M.Ing.
The Method
How a standard-machine detergent cleans without phosphates or quats
Four steps from a hard-water wash to a clean rinse that breaks down in treatment — built for agitators and top-loaders.
Soften the water, prime the load
Sodium carbonate and sodium citrate bind hard-water minerals and bring the wash water to working pH, so the surfactants spend their cleaning power on the laundry instead of fighting the water itself — less detergent, same clean.
Wetting and soil release
The surfactant blend — LAS, the Laureth-9 nonionic, and coconut-derived SLES — drops water's surface tension so it penetrates the fibre and pulls dirt off, not just over the surface.
Suspend the soil, full-suds for agitators
Cocamidopropyl betaine stabilizes a fuller foam suited to top-loading agitator and standard machines, holding lifted dirt in suspension so it rinses out instead of redepositing on fabric. (For low-suds HE front-loaders, the HE variant is the right tool.)
Rinse out, then break down
The surfactants flush from the load and break down in wastewater treatment to OECD 301D instead of building up in your watershed. No phosphates, no quats, no optical brighteners left behind on the fabric or in the water.

Format Matters
Read the formula, not the marketing
What separates this standard detergent from conventional and "eco"-labelled options — on the chemistry that ends up in your clothes and your watershed.
| Sampson Eco Laundry Detergent | Conventional drugstore detergent | "Eco" / greenwashed detergent | |
|---|---|---|---|
| Machine fit | Standard / agitator top-loaders (HE-compatible); HE variant for front-loaders | Usually one formula, suds not matched to machine | Rarely specifies standard vs HE |
| Phosphates | 0% (sodium citrate instead) | ≤0.5% (regulatory cap) | Usually phosphate-free, rarely disclosed clearly |
| Quats (quaternary ammonium compounds) | None — Quats-Free | Frequently used as antimicrobial / anti-static / softening | Often present, rarely disclosed |
| VOC content | None — water-based, no solvent carrier | High (chemistry-dependent) | Often undisclosed |
| Phthalates in fragrance | None — no synthetic fragrance carrier | Hidden under "fragrance" — not required to disclose | Often hidden under "fragrance" |
| Scent | Ships unscented; choose from 20+ natural essential-oil fragrances | Single proprietary fragrance — phthalate carrier likely | Single "natural" scent, source rarely disclosed |
| Surfactant origin | Coconut-derived (SLES, cocamidopropyl betaine) + LAS, full list disclosed | Petroleum-derived, partial disclosure | Mixed; "plant-derived" often unverifiable |
| Biodegradable to OECD 301D | Yes (disclosed on label) | No | Sometimes claimed, rarely certified |
The format is the difference. Same plant chemistry, same engineering rigor — without the bottle, the water weight, or the synthetic add-ons.
