Our requirements

It can be difficult to assess allergy risks by yourself - for many products, it is not possible at all, as manufacturers are not required to declare all ingredients. If you choose products labelled with The Blue Label, we have done the hard work for you.

Labelled products are required to make it...

  • easier to reduce the risk of developing a contact allergy
  • easier to avoid certain substances, if you have allergies
  • more attractive for manufacturers to develop products with a minimum of allergy risk

Why do we have these requirements?

Allergenic substances
All substances can cause allergy, but some substances cause allergy more frequently than others. Substances to which many people are allergic to are not allowed in products with The Blue Label.

These substances include but are not all:

  • Perfume – both natural and synthetic
  • Added formaldehyde or formaldehyde donors
  • Kathon, MI and MCI
  • Rosin

Certain extracts such as Aloe Vera are required to be purified from allergenic substances.

In addition dyes and pigments are not allowed to be in contact with the skin unless they serve a specific purpose eg in make up. 

Substances that can cause irritation
If the skin is irritated, there is a greater risk of developing allergy. Skin can become irritated in many ways, but some chemical substances can also irritate the skin. This is why we require for these substances to be found only in small amounts. How much is allowed depends on the other ingredients and the use of the product, e.g. whether the product is washed off (rinse-off) or stays on the skin (leave-on). Products are therefore always assessed individually.

In Kemilex, you can see all ingredients that we have assessed and our conclusion regarding allergy risk: those which are not allowed, those whose use is limited and those which can be used without problem.

We must have full insight into the ingredients

In order to assess whether a product can carry our allergy label, we require information on how the product will be used and on all its ingredients, including concentrations.

Some products, such as personal care products and detergents, are required to declare all ingredients on their label.
For other products, manufacturers may not be aware of all ingredients and some of the information may be confidential, so we do not require them to label their products with all ingredients. We require, however, that we are given access to the information, if neccesary we get it from sub-suppliers.
