The Blue Label has criteria that makes it easier for you to know how we assess the different products.

Products are labelled with The Blue Label to make it:

  • Easier to minimise the risk of developing skin allergy
  • Easier to avoid certain substances if you suffer from skin allergy
  • More attractive for manufacturers to develop products for consumers who would like to be extra careful

Allergenic substances

All substances can cause skin allergy - some substances more frequently than others. Therefore, we do not generally permit substances in products that carry The Blue Label, which are classified as sensitising, or are otherwise assessed as being frequently sensitising, given information from dermatologists, experts or other scientific literature.

We also require a high level of information about natural substances in order to ensure that they do not contain impurities that can pose problems. Therefore, we require that certain extracts, for example aloe vera, are to be purified of specific allergenic substances. For some metals and colophonium, we require that these have not been added to the material. If they are found to be unavoidable natural contaminants in raw materials, they must not exceed our limit values.



Basically, colourants are not permitted in products that carry The Blue Label because colours do not have a function in the products besides adding colour. However, colour does have an essential function in Diapers and makeup and is therefore permitted if it meets our requirements.

There are colourants in the printing found on diapers. The print serves to indicate the size of the diaper and the direction in which it should turn. The print must be placed where it will not come into contact with the skin and the colourants used must meet our standards with regard to the content of allergenic substances.

Colourants are a necessary component of makeup. To ensure that consumers who want to use makeup are able to choose products that minimise the risk of allergy, makeup carrying The Blue Label is available. Naturally the colourants have to meet our general requirements for allergenic substances, but they also have to meet a specific requirement for metal content.

Substances that can cause irritation

Irritation is not an allergy, but if the skin is irritated, there is a bigger risk of developing an allergy. You can irritate the skin in many ways, but some chemicals may also irritate the skin. Therefore, we only allow these substances to be used in small quantities. How much depends on the other ingredients and how the product is used for example, whether it is rinsed off or left on the skin. To assure the right handling, we always carry out a specific assessment of the individual product.

In Kemilex you can see our assessment of the ingredients assessed by The Blue Label - both the substances that we do not permit, substances with restrictions and substances that may be used in the products.

We must have full insight into the ingredients

It is important to know that we need information for all ingredients. To assess whether a product can carry our allergy label, we require information about all the ingredients that are used in the product, CAS no., and concentration as well as their function.

For certain products, such as personal care products and detergents, we require a full declaration on the products.

For other products, e.g. diapers, some of the formulations of the raw materials may be confidential. Here we do not require a full declaration on the product. However, to perform the assessment of the product, we must have access to detailed knowledge about the product. If a raw material is used for which the exact composition or ingredients are not known to the manufacturer, we must have this information from the relevant sub-supplier. Only with full knowledge of all information about the constituent raw materials are we able to make a full assessment of the product and make sure that it meets our requirements, both inside and outside.

With some products, it is also important for us to know what processes and process chemicals are used in the production. For these products, therefore, we also need this information to be able to assess the final product.

Special requirements for certain raw materials

Non-woven: We must know the production process and the chemicals that are used during manufacture. We need to know whether the process water that is used comes into contact with the raw material and, if so, we need to know all chemicals/biocides that have been added to the water. If the fibres have been treated, for example with a spin finish, we must also have data on all the chemicals used here.

Fluff/pulp/paper/viscose: We must know what types of wood have been used. If the wood pulp/cellulose comes from conifers, we need information about the content of colophonium or resin in the material. We also need to know the chemicals used during manufacture, from the washing and bleaching stages of the manufacturing process.

Colourants: Natural colourants may contain contaminants in the form of the metals nickel, chromium and cobalt. If the product contains natural colours, the manufacturer must conduct a test to prove that the total content for each of the different metals does not exceed 1ppm. You can find more detailed information about colourants and the documentation requirements we impose for testing products with colour, in the criteria for cosmetic products or the criteria for paper and hygiene products.

It is the responsibility of the manufacturer to ensure that our requirements are met at all times, and Asthma-Allergy Denmark may request documentation at any time to prove that the requirements are met - even after approval of the product.

Criteria documentation

To provide an overview of the different requirements set for The Blue Label we have developed a set of criteria for each of our product types and a specifications document for the natural ingredients. Our requirements reflect our desire to help people who are already affected by skin allergy and people who want to minimise their risk of developing skin allergy. The criteria documentation is divided separately according to the different areas they cover and therefore we do not have one comprehensive criteria document with all our requirements.
