Seal criteria

The products and services we certify have been fully adapted to the needs of allergy sufferers. An independent advisory panel of 15 leading international scientists and technicians has developed the criteria we use to evaluate different product groups, such as creams, vacuum cleaners and hotels. They include threshold values and exclusion criteria that make an allergic reaction very unlikely. The criteria are regularly updated to reflect the latest scientific findings. A product receives the Seal when it can be proved through external audits or studies that the criteria have been fulfilled.
