Because allergies can be triggered by individual components and materials, it is particularly important to provide sufferers full details of the ingredients used. People with allergies should select products that are free of preservatives and solvents. Products that have a high pH value to kill mold spores and bacteria are also beneficial.
If a product contains allergenic substances in a concentration above the nominal limit, the VdL requires a full declaration of ingredients and the establishment of an allergy advice service in the form of a hotline or an information section.
