Research you can see
We research ingredients, dosage, temperature and use. In our G6 laundry sheets you see that back in a five-enzyme system, each with its own job on different stain types.
What we stand for
Evidence-based cleaning. Distinctive scents.
Cosmeau is not a marketing layer on standard products. We develop, test and improve ourselves. From a five-enzyme system to scents where quality, experience and safety have to add up.

Emma · Mila · TimOur mission
Teaching the Netherlands to wash and clean smarter
A clean home does not have to revolve around more product, heavier bottles or the loudest promise. It starts with understanding what dirt does, which ingredients really add something, and how you dose a formula smartly.
That is why we combine research with practical everyday products. We want good cleaning to stay easy to understand, pleasant to use and fairly priced.
Four fixed principles
No story without substance
These are the choices we use to judge products and communication.
🌸
Scent as a craft
A good scent should open beautifully, stay pleasant and fit the product. We judge raw materials and compositions on scent quality, use and safety within current European rules.
🏭
Making more ourselves
By bringing research, production and packaging closer together, we learn faster and keep more grip on quality. A growing share happens in our factory in Velsen-Noord.
💶
Good should stay within reach
Innovation is only valuable when people get something from it every day. That is why we steer not only on performance and ease of use, but also on a fair price per use.
How we work
From question to a better formula
Research is not a white coat in an ad for us. It is a repeatable process of measuring, using and improving.
We start with the problem
Grease, protein, starch, scent experience or awkward dosing. First we make the real use question concrete.
We build and compare
We select ingredients and scent compositions on function, quality and fit for the job.
We test in real life
A formula must not only work on paper. We look at performance, ease of use, scent and stability in realistic situations.
We keep improving
Feedback, new knowledge and production experience go back into the next version. That is how G5 eventually became G6.
Product results can differ by stain, material, water hardness, dose and programme. That is why we give the most concrete use instructions we can per product.
Real work in the Netherlands
Research, production and execution closer together
In Velsen-Noord we build more knowledge and technique in-house, step by step.
To be clear: not every Cosmeau product is made in the Netherlands. Per product we say what is developed, produced or packed here.
Formula and scentProduct and scent development
In the Netherlands we work on formulations and scent concepts. We judge function, experience, quality and safety as one whole.
Own machineWe pack scent pearls ourselves
Our own packing machine makes local execution visible. We pack scent pearls in Velsen-Noord and can follow and adjust the process directly.
Partly own logisticsOwn storage, fixed partners
We manage our stock and storage in Velsen-Noord. We do part of the packing and shipping ourselves. For the rest we work with fixed logistics partners in the Netherlands.
Clear claims
Say exactly what applies
Trust does not grow from big words. It grows from checkable explanation.
This we do say
- ✓When a specific pack is plastic-free.
- ✓What role ingredients or enzymes have in a formula.
- ✓What is developed, produced or packed in the Netherlands.
- ✓That our logistics is partly in-house.
This we do not inflate
- ×We do not automatically call every product plastic-free.
- ×We do not say everything is made in the Netherlands.
- ×We do not present marketing language as scientific proof.
- ×We make no absolute performance promise for every stain or situation.
Value for more people
Research with a social side
We do not want to reserve knowledge and better products for a luxury niche. Fair prices belong to our mission. We also support social initiatives with product donations and practical help when we can.

Frequently asked questions
Our approach, briefly explained
Do you make all products yourselves in the Netherlands?
No. We develop products ourselves and a growing share of production and packing happens in Velsen-Noord. On product pages we say as specifically as we can what applies to that product.
What do you mean by evidence-based cleaning?
That choices in a formula must have a functional reason. We research ingredients, dose and use conditions, compare versions and improve from test results and real-world use.
Why do you use five enzymes in G6?
Different enzymes work on different dirt types, such as grease, protein or starch. Combining functions lets the formula tackle several common stain types. The result still depends on material, programme and dose.
Is Cosmeau plastic-free?
We do not use that claim as a general promise for the whole brand or every product. Where a specific pack is plastic-free, we say so on that product.
Do you handle all logistics yourselves?
No. We manage our storage in Velsen-Noord and do part of the packing and shipping ourselves. For other logistics work we use fixed partners in the Netherlands.
