You’re not paying for a little piece of paper. You’re paying for peace of mind, knowing what’s on your laundry.

Cheaper laundry detergent sheets from other brands may look similar. You only notice the difference when you look at what really goes into them. At EcoHaus, we don’t sell an impression or pretty words. We develop, test, and verify to make sure our laundry detergent sheets are:

Effective in everyday washes
Pleasant to use every day
Described honestly and clearly

That’s why they cost more. And why we stand firmly behind them.

We want more than just clean laundry.

Skin is our largest organ. That’s why it’s not enough for a laundry sheet to simply wash clothes. We also care about what remains in the fibers of our clothes after washing.

Because we wear clothes every day. We sleep in them. We exercise in them. And we dress our children in them.

That’s why, when developing our products, we focus not only on effectiveness, but also on:

Ingredients
Biodegradability
Overall impact and sustainability

Clean laundry is essential. But a top-quality product has to do more.

What’s really behind the price of EcoHaus laundry detergent sheets?

There's more behind each package than just production. There's also work that most customers don't see, but that makes all the difference:

Transparency and trust: Greater investment in certifications and supplier verification (supply chain management).
Authentic, future-proof ingredients
Effective for the whole family
Formulation development and laboratory testing that go beyond standard requirements
Biodegradability verification and efficacy testing

We don't cut corners when it comes to trust, effectiveness and safety. Choosing EcoHaus is the right choice.

What does this mean for you at home?

Does this mean you’re getting a product that’s designed to be:

Easy

No measuring, no sticky lids, no heavy gels.

Compact

It won’t take up half a cupboard or bathroom.

Pleasant

A subtle scent that isn’t overpowering, and more comfortable to use in everyday situations.

Trusted

You know why you use it and what lies behind it.

Laboratory-verified as safe for human skin and clothing at the Technical University of Liberec

We don’t just sell claims. While ordinary products meet only the basic legal requirements, we go beyond what is mandatory. Our sheets have undergone independent laboratory assessment of their composition, biodegradability (ability to break down in nature) and the safety of textiles after washing.

At the Technical University of Liberec, textiles washed with selected scents were confirmed to be gentle to people and nature (biocompatibility) and non-irritating to the skin.

Biodegradability tested according to OECD

We don’t just claim biodegradability – we have had it laboratory-tested according to the international OECD 301F method. The test shows that the tested scents of EcoHaus laundry detergent sheets are able to biodegrade. Simply put, the substances gradually break down with the help of microorganisms and do not remain in the environment long-term.

High concentration of active washing agents verified by laboratory tests

The composition was analysed at CXI – the Institute for Nanomaterials, Advanced Technologies and Innovation of the Technical University of Liberec, a leading research centre focused on materials and chemical analysis. The laboratory determined how much active washing agent the sheets actually contain.

The result showed that roughly one third of the sheet consists of active washing agents (surfactants). The rest consists of components that help the wash work properly, such as water softeners, stabilising components and the soluble structure of the sheet that holds the washing agents together. These components are a standard part of modern detergents and allow the sheet to dissolve quickly in water so that the washing agents can work effectively. This makes the sheet not just a carrier of detergent, but its concentrated form.

Verified by sustainability experts

We regularly consult our claims with sustainability experts from EnviTrail, who specialise in carbon footprint calculations, product life cycle assessment (LCA) and impacts on the environment, society and corporate governance (ESG reporting). This means we only communicate what we can back up with data, methodology or standards, and avoid vague claims such as “eco” or “planet-friendly”. Our goal is for product information to be clear, verifiable and transparent.

Verified for safe contact with skin

In a laboratory assessment, textiles washed with EcoHaus sheets were rated as non-irritating (not irritating) to the skin.

We tested safety using modern laboratory methods on human cell cultures. A human skin model is used (for example keratinocytes or the EpiDerm model), which makes it possible to verify whether substances irritate the skin and whether textiles are safe for skin contact after washing.

And the result? Textiles washed with EcoHaus sheets were rated as non-irritating to the skin.

More about our work on sustainability

Development is more than just a formula.

Developing a high-quality product is about more than just mixing ingredients and making packaging. Every EcoHaus product involves:

formulation development
laboratory testing
stability testing – scientific tests that determine how the quality, safety, and effectiveness of cleaning products change over time under the influence of factors such as temperature, humidity, and light
safety documentation
effectiveness and compatibility verification

Our Pillars

Functionality

The biggest barrier in this category is the lack of trust that laundry detergent sheets actually work reliably. That’s why we speak clearly about their performance, dosage, and real customer experiences.

Science and Testing

We work with the Technical University of Liberec and experts. We test biodegradability, biocompatibility, and composition, and make sure our claims are accurate.

Transparency

We don’t sell an eco-friendly image. We calculate our carbon footprint, rely on standards, and review our communications to guard against greenwashing.

Local impact

We are building EcoHaus as a brand rooted in Czech development, education, and a long-term ambition to move household products toward higher quality and greater trustworthiness.

Functionality for Real-Life Laundryying

The brand was founded by Czech entrepreneur Petra Doubková, who began working on household cleaning products during a startup competition at the Technical University of Liberec. We built the brand step by step, without investors or big budgets.

Today, EcoHaus is built primarily on the trust of our customers and a community of people who want effective, more responsible products for their homes.

A social enterprise that employs people with disabilities also helps manufacture and assemble our products. This way of producing them costs more than fully automated assembly-line production, but we believe business can also have a positive social impact.

That’s why we’re grateful for every purchase, which allows us to continue developing and improving our products.

Frequently Asked Questions

Why are EcoHaus laundry detergent sheets more expensive?

EcoHaus laundry sheets aren’t just another generic wholesale product.

Several years of work, testing, and collaboration with experts have gone into developing them. We didn’t want to create the cheapest laundry sheet on the market, but a product that really works and is safe for people and the environment.

We test the ingredients and safety, verify biodegradability, work with a university, and communicate without greenwashing.

That’s why the price reflects not only the laundry sheet itself, but also development, testing, and transparency.

What does “100% biodegradable” mean?

This means that the substances in the product can naturally break down through the action of microorganisms in the environment. The biodegradability of some varieties of EcoHaus laundry detergent sheets was tested according to the international OECD 301F method, which simulates real-world environmental conditions.

The results showed almost complete biodegradation, meaning the substances gradually break down and do not remain in the environment for a long time.

If you’d like to know more, check out our Sustainability page.

What does it mean that you have an analyzed composition?

This means we didn’t just verify the product’s composition on paper using information from our raw material suppliers—we had it independently analyzed in a laboratory.

Thanks to this analysis, we have verified what the paper actually contains and don’t rely solely on claims made by the manufacturers of individual ingredients. This helps us communicate the composition transparently and based on data, rather than just marketing claims.

What does EcoHaus do differently from cheaper toilet paper brands?

At first glance, they may look the same. The difference lies in who develops the product, whether it is tested, and whether the brand communicates transparently.

While competitors often cut corners on certifications and the supply chain, we invest in them. Our formula is future-proof (ready for stricter standards in the future); we go beyond mandatory testing and verify our claims. EcoHaus is a Czech brand that invests in development, testing, and open communication.

Why is transparency important to you?

There are many marketing claims about sustainability today. That’s why we work with sustainability experts (such as EnviTrail) and strive to communicate only what we can substantiate. Our goal isn’t to appear “eco-friendly,” but to be truly responsible.

Who is behind the EcoHaus brand?

EcoHaus was founded by Petra Doubková while she was working on a premium drugstore project during a startup competition at the Technical University of Liberec. The brand was built without investors and gradually grew through its customer community.

Who is involved in the production?

A social enterprise employing people with disabilities contributes to the production process. This method of production is more costly than automated assembly-line production, but we believe that business can also have a positive social impact.

What substances do laundry detergent sheets contain?

Laboratory analysis showed that approximately one third of the sheet consists of active cleaning agents (surfactants).

The rest is made up of ingredients that help the detergent work, such as water softeners, stabilizing ingredients, and the soluble structure that holds the sheet together. These ingredients are commonly found in modern laundry detergents.
