OUR STORY

The Engineers Behind the Soap

For 25 years, Diana and Angelo cleaned up some of the worst environmental contamination in Canada—oil spills, landfills, industrial disasters. As environmental engineers, they know exactly what toxic chemicals do to human health.

Then one day, they read the label on their son's soap.

'We saw the same endocrine-disrupting chemicals we'd been cleaning up for decades. In our own bathroom,' Diana recalls. 'We realized the consumer soap industry was doing to families what industrial pollution does to the environment—slowly poisoning them.'

That's why they founded Sampson Eco Shop. They brought their engineering rigor to soap-making, partnering with master craftspeople in Provence who have been perfecting this recipe for 600 years. Every batch is tested. Every ingredient is vetted. No greenwashing. No shortcuts.

Today, 20,000+ Montreal families trust Sampson. They're not just buying soap—they're joining a movement toward intentional, transparent consumption.

Frequently Asked Questions

Will this work for my sensitive skin/eczema?

Yes. Our 4-ingredient formula is specifically designed for sensitive skin. We have hundreds of verified reviews from customers with eczema, psoriasis, and dermatitis reporting significant improvement. If you have severe skin conditions, we recommend a patch test first. And remember—30-day satisfaction guarantee means you can try risk-free.

How long does one bar last?

A single bar lasts 2-3 months with regular daily use (shower or bath). This is because traditional Marseille soap is more concentrated than commercial bars. Most customers find it significantly more economical than conventional soaps once they account for longevity.

How is this different from grocery store soap?

Most commercial soaps are mass-produced with 10-15 synthetic ingredients including parabens and phthalates. Our soap uses a 600-year-old recipe with only 4 natural ingredients, handcrafted in Provence, and tested by environmental engineers. We're proof that you don't need chemicals to get clean.

Is this soap truly eco-friendly or is it greenwashing?

This is a fair skepticism we appreciate. Our soap is ECOCERT certified (independent verification), uses zero-waste kraft paper packaging, and is made using traditional cauldron-cooking methods. The recipe has been unchanged for 600 years—sustainability isn't our marketing strategy; it's our foundation.

Does it lather well?

Absolutely. Despite the minimal ingredients, Marseille soap produces a rich, creamy lather. The 70% olive oil provides emollient properties while the 30% coconut oil creates the satisfying lather you expect from quality soap.

What if I don't like it?

We offer a 30-day satisfaction guarantee. If you're not completely satisfied, we'll provide a full refund—no questions asked. We're confident in our product, and we want you to be risk-free.
