In order for cosmetics to be certified, they must contain the 26 potentially allergenic substances in only very limited quantities. The Allergy Seal of Quality bans them at concentrations that are 10 times lower than specified by Swiss law. In addition to the basic requirements listed above, the claims "without perfume/without fragrances" and "without dyes" are also tested if they are advertised or used on the packaging.

The detailed criteria for the certification of cosmetics and a list of ingredients that are permitted only to a limited extent can be found here.
