Research and production in the Netherlands

From formula to finished product.

We develop our formulas and fragrances in the Netherlands. A growing part of our production and packaging takes place in Velsen-Noord; We also manage our storage there and do some of the logistics.

Our path to in-house production

Learn. Testing. Make it yourself.

Our mission takes shape by bringing more knowledge and processes in-house. Not in one leap, but demonstrably step by step.

Explanation at a laundry sheet production installation

The first local production step

We started with a five-machine laundry sheet line. Too complex as a first production line, but an important learning path.

Why Cosmeau

Why Cosmeau works differently

It's not just what's in the packaging that counts, but also who develops and makes it. With our own R&D and lab in the Netherlands, our own production machines and a growing part of production and packaging in Velsen-Noord, we keep knowledge close by. This way we can improve faster and keep quality at an accessible price.

Vergelijking op merk- en bedrijfsmodel. Per merk en per product kan de praktijk verschillen. Bij Cosmeau geldt eigen productie in Nederland voor een groeiend deel van het assortiment; productpagina’s blijven leidend voor productspecifieke claims.

What laundry lovers in the Netherlands think

Reviews from daily routines: laundry, cleaning and less hassle.

★★★★★
It was really clean!

Easy to use, and the washing machine smells less often because soap residue does not build up.

JH69 · 50-59 jaar · geverifieerd
★★★★★
Very cheap per wash

In the largest pack you land around 16 cents per wash. Better for the planet and your wallet.

★★★★★
Great product

Smells fresh and looks clean. I bought it because I no longer wanted to grow the plastic waste mountain.

AMEVG · 60-69 jaar · geverifieerd
★★★★★
No more lugging around

No more heavy bottles at home and the sheets take almost no space. Perfect for our small laundry room.

Marieke · Utrecht · geverifieerd
★★★★★
Fresh laundry, compactly packaged

The scent is subtle and fresh. What I love most is that the packaging fits through the letterbox.

Sanne · 30-39 jaar · geverifieerd
★★★★★
My family is gone

We now use sheets, dishwasher tablets and scent pearls. Less clutter in the cupboard and everything smells clean.

About Cosmeau

FAQ about who we are and how we work

From our factory and scents to warehousing and shipping: this is what you want to know before choosing Cosmeau.

Where are Cosmeau products developed and made?

We develop our products ourselves and produce a growing number at our own location in Velsen-Noord. For each product, we show as clearly as possible how and where it is made.

What happens at your site in Velsen-Noord?

We have approximately 2,000 m² of factory and 2,500 m² of warehouse there. Product development, a growing part of our production, storage and part of packaging and shipping come together here.

Do you develop the scents yourselves?

Yes. We develop our unique fragrances ourselves within the EU and choose each raw material according to our own quality standards. There is also a variant without added perfume.

What do you mean by checks at ingredient level?

We not only assess the final scent, but each raw material used separately. We exclude substances that are considered hormone disruptors according to our quality standard. That is an extra quality choice; no medical guarantee.

What do you handle yourselves for warehousing and shipping?

We manage our stock and warehousing in Velsen-Noord. We handle part of packing and shipping ourselves; for the rest of logistics we work with trusted partners in the Netherlands.

How does Cosmeau help to use less plastic?

Where possible, we opt for compact formulas, refillable or recyclable solutions and packaging with as little unnecessary material as possible. We explain the choice we have made for each product.

Can I follow your production and developments?

Gladly even. In our blogs and production updates we share new machines, formulas, tests and improvements behind the scenes. You can also register for our mailings.

When will my order ship?

Shipping details are shown at checkout.
