The present invention relates to complexed metal salts which comprise ligands and at least one complexing agent for chemically binding noxious substances and/or odor-forming substances, the ligands comprising a hydrophobic carbon skeleton with hydrophilic groups. The complexed metal salt formed with the complexing agent is water-soluble and surface-active. Preferred complexing agents are water-soluble acids or salts of at least bifunctional acids, or also ether carboxylic acids.
