In order for detergents and cleaning agents (chemical products) to be certified, they must contain the 26 potentially allergenic substances only in very limited quantities. The Allergy Seal of Quality bans them at concentrations 10 times lower than the Swiss law.

In addition to the above-mentioned basic requirement, the claims "without perfume / without fragrances", "without colorants" as well as "without enzymes" are checked if these claims are advertised or used on the packaging. Unlike the 26 potentially allergenic substances, these three claims are not checked as standard.

The criteria for the certification of detergents and cleaning agents as well as a list of ingredients that are permitted only to a limited extent can be found here.
