Frequently asked questions

Recycling of diapers and care products

Moomin Baby diapers are completely chlorine-free, which makes them suitable for energy waste and incineration, as they do not emit harmful emissions into the atmosphere. It is not recommended to dispose of chlorinated diapers by incineration, as incineration can produce toxic gases. However, not all incinerators accept any diapers, as some of our competitors still use chlorine-bleached diapers. We therefore recommend that you ask the incinerator in your area about their policy and whether they accept non-chlorinated diapers for incineration.

You can also dispose of Moomin Baby diapers in the normal way with mixed waste. Whichever way you dispose of Moomin Baby diapers, we can say that our diapers are an environmentally responsible choice among other disposable diapers. We have designed the life cycle of our diapers to have the least possible impact on the environment. The main raw material for Moomin Baby diapers is degradable cellulose, made from domestic FSC-certified forests. We also try to always choose Nordic raw material manufacturers and do not add any unnecessary chemicals such as fragrances or oils to our diapers.

Finished diapers are packed in a packaging bag made from 60% recycled plastic, which you can sort for plastic recycling. Moomin Baby diapers are also made in Finland, so trips from factory to store shelf are short. We want to leave a clean and beautiful nature for future generations.

Helmi Baby biodegradable wipes are made of 100% viscose. It contains soothing allantoin and moisturising glycerine. It contains no dyes, fragrances or skin irritating alcohol. The wipe is vegan and biodegradable, so it can be recycled in your home compost, composting toilet or organic waste.

Skin-friendliness and use of diapers and skincare products

Diaper rash is usually the result of many factors. The term diaper rash is known as irritant rash caused by fecal matter and urine, which is also affected by the child’s diet or changes in it. The frequency of diaper changes is also an important factor, and the diaper should be changed about 5-6 times a day, so that the child’s sensitive skin is not in contact with pee or fecal matter for too long. However, it should be remembered that diaper rash or reddening of the skin in the diaper area can occur even if you are very careful. A skin reaction can also sometimes be caused by diarrhoea or a medical treatment, in which case it is a good idea to remember to change the diaper more often in a day. Feces, especially diarrhoea, contain various skin irritants that cause skin irritation and diaper rash.

Moomin Baby diapers are made of breathable materials, which allows the skin to breathe better even during diaper use. Our diapers also meet the very strict criteria set by the Allergy, Skin and Asthma Federation and the Nordic Swan Ecolabel for the materials used in the manufacture of diapers.

The best way to avoid diaper rash is to give your baby air baths, which means letting your child go without a diaper for a few hours during the day. It is also important to let the skin dry before putting on a new diaper. Diaper rash should be treated with appropriate creams and if the skin is very irritated and red, we recommend a visit to the doctor so that a professional can check that the skin is not inflamed.

Also remember to wean your baby from diapers sooner rather than later. This is important both for the baby’s skin as well as for the environmental stress caused by the diapers.

Skin-friendliness is one of the most important values for us, along with environmental responsibility. We do our best to ensure that our diapers are suitable for even the most sensitive baby skin.

Skin-friendliness is influenced by many different factors, such as the materials used in the production and the fit of the diaper. The raw materials used in our diapers are carefully selected, using only soft and safe materials. Wherever possible, we favour Nordic raw material manufacturers. We do not add any unnecessary chemicals such as oils or fragrances to our diapers. The main raw material used in our diapers is domestic cellulose, which is completely chlorine-free, and therefore also dioxin-free. The cellulose we use is not bleached with chemicals but with 100% pure oxygen. This is a safer and more skin-friendly solution for the child’s skin as well as for our environment.

Moomin Baby diapers also contain no allergenic substances such as latex, glyphosate, formaldehyde or phthalates. When it comes to skin-friendliness, the fit of the diaper is also important. When the diaper fits the baby well, the child will not develop skin irritating abrasions or harmful imprints. The fabrics and plastics used in Moomin Baby diapers are highly breathable, so that the baby’s skin can breathe even when the diaper is being used. The carefully selected materials also absorb the liquids in, keeping the baby’s skin dry so that the diaper does not irritate the skin.

We are also constantly working towards making diapers that are more skin-friendly. Moomin Baby diapers are made in collaboration with the Allergy, Skin and Asthma Association and we will continue our long-standing collaboration in the future. Our diapers are also dermatologically tested.

When it comes to skin-friendliness, the right size and a good fit is important. When the diaper is the right size, your baby will not develop skin irritating chafing, harmful impressions or leakages. The fit and correct size of a diaper can sometimes be difficult to judge, which is why Moomin Baby invests in the fit of the diaper, making your child’s daily life easier. Pay attention to the following points when choosing the right nappy size, because if any of the following is true, the diaper size you are using is the wrong one for your baby:

  • The diaper gets drenched or your baby has leakage accidents.
  • The diaper does not completely cover the baby’s buttocks.
  • The diaper looks or feels too tight.
  • The tightness is right if you can slip a few fingers between the diaper and the baby’s stomach.
  • The diaper leaves a red scuff mark on the waist or inner thighs.

Moomin Baby diaper sizes are graded according to baby’s weight. You will find clear size markings on both the diaper package and the diaper itself. The Moomin Baby diaper chart helps you to judge which size diaper is best for your baby.

For us, skin-friendliness is one of the most important features of a diaper. That’s why we only want to make clean and soft diapers for even the most sensitive baby skin. Moomin Baby diapers do not contain any unnecessary added chemicals. We do not add any fragrances, creams or dyes to the finished diapers. Moomin Baby diapers are only made from carefully selected clean and safe materials. Moomin Baby diapers are certified by the Nordic Swan Ecolabel and the Allergy, Skin and Asthma Federation, which means that the manufacturing process and the materials used meet the strict criteria of these certifications. We feel that this is only a minimum requirement and we are constantly striving to improve our products to make them even safer. It is very important for us to keep the diaper as clean and additive-free as possible in the future.

Moomin Baby tape diapers in sizes 1, 2 and 3 have a handy wetness indicator, which appears as a yellow line on the diaper when it is dry. When the diaper gets wet, the wetness indicator turns bluish or blue, indicating that it is time to change the diaper to new one.

The main absorbent used in Moomin Baby diapers is pure Finnish cellulose, from sustainably managed forests. To ensure that the diaper has sufficient absorbency and stays dry, a small amount of a moisture-absorbing powder called superabsorbent (SAP) is mixed with the cellulose. The superabsorbent we use is completely safe and hypoallergenic, and is also used in the food industry. It has been used for decades in diapers, menstrual pads, urinary incontinence pads, etc.


The bright balls in a child’s diaper are precisely this moisture-retaining absorbent powder, which turns into a gel-like substance, visible to the eye, when the liquid is absorbed. It binds not only liquid but also odour, helping to keep the diaper surface dry. It also prevents the spread of bacteria, rashes and other skin problems. Gel balls in the diaper or on the skin are not harmful to the baby. The absorbent powder binds moisture to the absorbent layer of the diaper, and normally gel balls do not rise to the surface of the diaper. However, this sometimes occurs when the diaper is very wet. We recommend changing the diaper more frequently.

Helmi Baby Mats changing mat replaced the previous Helmi Baby moisture protective mat and they differ in their intended use. The new disposable Helmi Baby Changing Mat is designed to provide short-term protection for changing diapers both at home and when travelling outside the home. It is convenient and easy to slip into your baby’s changing bag thanks to its small size. The old moisture protective mat was suitable for longer-term use to protect the baby’s cot, for example at night.

Manufacture of diapers and baby care products

The main absorbent used in our diapers is pure, 100% FSC® certified cellulose from Finnish forests. The cellulose we use is bleached with oxygen and is therefore 100% chlorine-free. The absorbent core is wrapped in a non-woven fabric with liquid-permeable and repellent properties. A small amount of superabsorbent is mixed with the cellulose in the absorbent layer. The superabsorbent (SAP) we use is a completely safe, hypoallergenic substance that has been used in children’s diapers for over 20 years and has been proven safe. We are constantly striving to make our diapers more eco-friendly and therefore use significantly less superabsorbent than many leading brands. Despite this, our diapers work efficiently, their design evenly distributes moisture throughout the diaper and keeps skin dry.

The top and outer layers of our diapers, which are in direct contact with baby’s skin, are made of soft and skin-friendly materials. The inside is made of polypropylene fibre fabric and the outside of the diaper is made of breathable polyethylene plastic and a non-woven fabric blend of polypropylene and polyethylene.

Diaper fasteners such as tapes are made of polypropylene and polyethylene and leakage guards are made of polypropylene plastic. All the adhesives used in the sheaths are FDA-approved hot melt adhesives, the same as those used in the food industry, for example in chocolate wrappers.

Moomin Baby diapers are an all-round carefree and safe choice for your child, as all the raw materials used meet the strict criteria for chemicals set by the Nordic Swan Ecolabel and the Allergy, Skin and Asthma Federation. Moomin Baby diapers never contain fragrances, dyes or creams that can irritate baby’s delicate skin.

The cellulose we use is bleached with 100% oxygen. This is a much safer solution for the skin and the environment than chlorine bleaching and makes the diaper dioxin-free. There are also chlorine bleached diapers on the market that may irritate your child’s skin and have been found to contain dioxin residues. The disposal of chlorine-bleached diapers is also more complicated as they are not suitable for energy waste. Furthermore, no optical brighteners have been added to our cellulose. We want to keep our diapers as clean and chemical-free as possible.

The main raw material used in Moomin Baby diapers, cellulose, is fully biodegradable. Other materials, such as non-woven fibres, are also used, but these are not biodegradable.

There is currently no fully biodegradable disposable diaper on the market, but the share of biodegradable raw materials is increasing and new, more environmentally responsible raw materials are being developed.

When considering the environmental impact of diapers, the whole life cycle of the diaper, from raw material to manufacture and disposal, must be taken into account. Moomin Baby diapers are now 100% carbon neutral. Moomin Baby diapers are made from carefully selected, clean and safe raw materials. We also always try to choose Nordic suppliers of raw materials. Only less than 1% of needed raw materials come outside of Europe. The domestic cellulose used in our Moomin Baby diapers is completely chlorine-free, as the cellulose we use is bleached with 100% pure oxygen. This is the safest solution for both the environment and your baby’s skin.

It should also be noted that almost no waste treatment plants accept biowaste containing human excreta. The reason for this is the safety of the staff of the waste treatment plant. Moomin Baby diapers are chlorine-free and can therefore be disposed of as energy waste.

The finished diapers are packed in a 60% recycled plastic packaging bag, which you can sort for plastic recycling.

Moomin Baby diapers differ from a regular disposable diaper in many ways, except for their absorbency. The biggest differences are, for example, the choice of raw materials, as all diapers are made from many different materials. The raw materials used in Moomin Baby diapers are carefully selected and meet the criteria of the Nordic Swan Ecolabel and the Allergy, Skin and Asthma Federation. The source of energy used in the production process also distinguishes eco-diaper manufacturing from regular diaper manufacturing. We use only solar energy and certified hydroelectric power to make Moomin Baby diapers – these renewable energy sources do not emit any carbon emissions. The heat generated in the production process is used to heat the production hall. The third major difference is the management of production waste; none of the waste from our production goes to landfill, all waste is recycled or incinerated for energy.

Moomin Baby diapers are manufactured taking into account the whole life cycle of the product from an environmental point of view, from the production of raw materials to the production of the diapers, the energy sources used, wholesale logistics and waste management. We are proud to say that Moomin Baby diapers are 100% carbon neutral. You can read more about our sustainability credentials here.

During our production process, no landfill waste is generated and all waste is recycled or incinerated for new energy. Furthermore, the production of Moomin Baby diapers does not result in any harmful emissions to air or water. We only use solar energy and certified hydro-electricity. These renewable energy sources do not emit any carbon emissions into the environment. We at Moomin Baby want to ensure a clean environment for future generations, which is why our diapers are now 100% carbon neutral. Read more about our sustainability credentials. We also use the heat generated in the production process to heat the production hall. Moomin Baby diapers are also made in Finland, making trips from factory to store shelves and homes much shorter. Also, remember to wean your baby from diapers sooner rather than later. This is important for both the baby’s skin and the environmental impact of the diapers.

The Helmi Baby disposable diaper changing mat and the Helmi Baby cleaning wipes, both normal and biodegradable are manufactured in Finland .
