EcoHaus Laundry Sheets for Wool and Silk, 60 Washes, Meadow Flowers

Find an overview of testing and measurements on our Sustainability.

Yes.EcoHaus laundry sheet variants were tested by the Technical University of Liberec laboratory using OECD 301 F methodology. The whole product was dissolved in a standard test medium with microorganisms from a wastewater treatment plant. After 28 days, all tested variants exceeded the 70% threshold used in the report to classify the product as biodegradable. Results ranged from 82.33% to practically complete biodegradation. (The variants were Unscented, Divine Lavender, Meadow Flowers, Cotton Magic, Sea Breeze and versions for black laundry.)

Biodegradability was tested by the Technical University of Liberec laboratory using OECD 301F methodology. The whole product was dissolved in a standard test medium with microorganisms from a wastewater treatment plant.

Yes. One sheet is enough for normally dirty laundry; for a large load, we recommend 1.5–2.

Whites, colours and delicates. Mums also successfully use them on children's clothes and socks. For black laundry, we recommend our special laundry sheets for dark clothes.

No. The sheet gives laundry a gentle scent without a chemical smell. For a stronger fragrance, customers often add our laundry perfume.

Because it is concentrated. After washing, it leaves a delicate, clean fragrance that customers describe as pleasant and unobtrusive.

Yes. Customers tell us:
“Finally, no itching after washing.”
“My son with eczema tolerates them really well.”
Of course, everyone's skin is different. If you experience difficulties, we particularly recommend the unscented version.

Yes. Customers most often praise their results on children's stains, towels and smelly T-shirts.

For especially stubborn stains, we recommend PUER or TAED.

Yes. Testing and customer feedback show that the sheet dissolves quickly without leaving residue.

Yes. Our customers often dissolve half a sheet in warm water to handwash delicates or sportswear. Mums and sports enthusiasts particularly use them this way.

The sheets keep well, but it is best to close the packaging. Feedback shows that very damp conditions may moisten the packaging, but the sheets themselves continue to work without problems.

The product contains surfactants for effective washing. Under the applicable classification, it carries hazard statement H412: “Harmful to aquatic life with long lasting effects.” We therefore advise against discharging wash water directly into the natural environment.

The sheets work well from 30°C. Customers often report trying 30°C for the first time and finding their laundry “as clean as at 60°C”.

Yes. They were tested in various regions of Czechia and Slovakia, including places where customers face hard water. The result? The same effectiveness and no sheet residue.

Yes, they do not burden domestic treatment systems.

Customers sum it up best: “I thought it would be another product that doesn't work... and it pleasantly surprised me.”

The sheets clean well, are easy to use and suitable for travelling, and have a lower environmental footprint.

Yes. Travel enthusiasts often mention this as a top advantage. They take up little space, can go in hand luggage, cannot spill and save you searching for detergent abroad.

It depends on how often you wash. For an average household washing 3–4 loads a week, it lasts 1–2 months.

No. Although our sheets are readily biodegradable, they are not intended for direct discharge into natural aquatic ecosystems. Nine variants of EcoHaus laundry and dishwashing sheets were tested by the Technical University of Liberec laboratory using OECD 301 F methodology. The whole product was dissolved in a standard test medium with microorganisms from a wastewater treatment plant. After 28 days, all tested variants exceeded the 70% threshold used in the report to classify the product as biodegradable. Results ranged from 82.33% to practically complete biodegradation.

However, biodegradability does not mean immediate harmlessness to aquatic organisms. We therefore recommend using the product only in a normal wastewater system where biological treatment subsequently takes place.

Yes. Customers often tell us they wash dog clothing, toys, harnesses and beds with the sheets.

Yes. Customer feedback shows that sports enthusiasts and mums often dissolve half a sheet in warm water and handwash the stain first.

No. If this does happen on a rare occasion, it is usually because the machine is overloaded. Simply place the sheet at the bottom under the laundry.

Yes, but subtly. Customers appreciate that laundry smells clean rather than perfumed. For a stronger scent, they add laundry perfume.

Yes. Mums often say the washed laundry is not overly fragranced.

No. Sheets dissolve completely without residue. They also do not clog dispensers like liquid or powder detergents.

Yes. Nursery staff also tested them in our study and praised their effectiveness and gentle scent.

Wool, merino and silk are animal fibres made of proteins. That is why we left enzymes out of the formula entirely.

We also reduced the proportion of strongly degreasing non-ionic washing ingredients and set the pH close to neutral. The formula is designed specifically around these materials' properties.

Washing ingredients
Release sweat, light grease and everyday dirt from fibres.

A gentler amphoteric washing ingredient
Complements washing performance without enzymes.

An anti-redeposition polymer
Helps keep loosened dirt dispersed in water so it does not settle back onto fabric during washing.

pH 6.5–7
The formula has a near-neutral pH, chosen with the properties of wool and silk in mind.

We deliberately left lanolin out of the solid sheet. It would be difficult to distribute evenly, harder to dissolve in cold water and could reduce storage stability.

The sheets therefore wash wool but do not replenish lanolin in the fibres.

• wool jumpers and accessories,
• merino clothing,
• silk,
• wool and silk blends,
• other sensitive materials whose care labels allow washing in water.

Place the sheet directly in the drum under the laundry. Choose a wool or delicate programme and follow the temperature and spin instructions on the care label.

For handwashing, first dissolve the amount of sheet you need in water.

Do not use on dry-clean-only items.

Even a special detergent cannot prevent shrinkage or felting if you choose too high a temperature, an unsuitable programme or intensive spinning.

Do not use sportswear sheets on wool, merino or silk. They contain protease, which is unsuitable for animal fibres.

We designed the formula without enzymes and with a near-neutral pH of 6.5–7.

It also contains fewer strongly degreasing non-ionic washing ingredients than the regular version. It is designed around wool, merino and silk, which need different washing from ordinary cotton or synthetics.

You can, but we recommend the special version designed specifically for these materials.

Regular sheets are designed for everyday cotton, synthetic and mixed-fibre laundry. The wool and silk version has a near-neutral pH and an adjusted balance of washing ingredients for sensitive animal fibres.

They cannot guarantee this on their own.

Shrinkage and felting also depend on temperature, drum movement, wash duration and spin intensity. Always combine the sheets with a wool or delicate programme and follow care symbols.

Do not wash dry-clean-only items at home.
