Abstract
Aqueous air-freshener gels having an increased content of perfume are prepared by homogeneously mixing the perfume with one or more solid inorganic carriers selected from the group consisting of magnesium, oxide powder, active carbon, zeolites and absorption agents based on silica and then combining the homogeneous mixture obtained in this way with an aqueous gel or the gel forming components. In the case of absorption agents based on silica or zeolites the further use of a non-ionogenic emulsifier is required.
