What Customers Say After the Switch
From greenwash-burned shoppers to allergy households — here's what changed when they swapped in Sampson.
I love this dish soap. Great quality and very effective in getting dishes clean. The scent is really nice as well.
I love the eucalyptus lavender scent. I used to live in Montreal but now I travel from Bromont to get it. I converted my household to these products and have noticed my skin sensitivity has diminished. Fabulous.
Small amount gets through a sink full of dishes.
Smells fresh. Goes on a long way, little goes far.
Greenwashing's favourite category
Plant-based dish soap should cut grease. Most "green" dish soaps are diluted to fail.
The eco dish soap aisle is full of products that under-deliver against conventional detergent — and the buyer goes back. Sampson Eco Dish Soap is built on a coconut-derived surfactant system paired (not overloaded) to cut kitchen grease, dried sauce, and cooked-on food residue at conventional-detergent strength.
Sodium Lauryl Sulfate — the petroleum surfactant most conventional dish soaps are built on — is the dermatology gold-standard irritant control in skin patch testing. 20+ years, 43,000+ patients tested. (German Contact Dermatitis Research Group / European Society of Contact Dermatitis baseline series)
Phthalates hide under "fragrance" — no disclosure required (EWG)
~50% of global surfactant consumption is household — most of it ending up in waterways (Arora 2022)

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 Sampson Eco Dish Soap Cuts Grease.
Four steps. Coconut-derived surfactant system at conventional-detergent strength — without the petroleum chemistry that conventional dish soap leans on.
Step 1 — Wetting + grease cut
Drops water's surface tension so it penetrates greasy dishes — without the dermal-irritation profile of conventional petroleum-surfactant dish soaps.
Step 2 — Emulsification + skin protection
Breaks grease into water-suspendable droplets — and combines coconut-derived surfactants so the formula stays gentle on hands across long dish-washing sessions.
Step 3 — Chelation + alkali boost
Binds water hardness and brings the wash to grease-cutting pH so the formula works on any tap water — soft or hard.
Step 4 — Rinse-out, then break-down
Surfactants flush down the drain and break down in wastewater treatment instead of persisting in the watershed.

Format Matters
How Eco Dish Soap Compares to What's On The Shelf
Dish soap is greenwashing's favourite aisle. Here's the chemistry behind the labels.
| Sampson Eco Dish Soap | Conventional drugstore dish soap | "Eco" / greenwashed dish soap | |
|---|---|---|---|
| Surfactant origin | Plant-derived (coconut) | Petroleum-derived (often SLS-based) | Mixed; rarely disclosed |
| Phthalates in fragrance | None — no sulfate-based fragrance carrier | Hidden under "fragrance" — not required to disclose | Often hidden |
| Scent | Ships unscented; choose from 20+ natural essential-oil fragrances | Single proprietary fragrance — phthalate carrier likely | Single "natural" scent, source rarely disclosed |
| Phosphates | None | ≤0.5% (regulatory cap) | Usually phosphate-free |
| VOC content | None | Variable, undisclosed | Sometimes disclosed |
| Biodegradable to OECD 301D | Yes | No | Sometimes claimed |
| Cuts grease at conventional-detergent strength | Yes | Yes (the petroleum-driven baseline) | Often diluted to fail |
The format is the difference. Same plant chemistry, same engineering rigor — without the bottle, the water weight, or the synthetic add-ons.
