  • sage oil chamomile oil, clove oil, lemon balm oil, mint oil, cinnamon leaf oil, linden tree oil, juniper berry oil, vetiver oil, oliban oil, galbanum oil, labolanum oil and lavandin oil.
  • Perfume solubilizers which can be used in the agents according to the invention are polyol fatty acid esters, for example glycerol alkoxylated with 7 moles of ethylene oxide, which is esterified with coconut fatty acid (Cetiol HE®, Henkel KGaA) and / or hardened castor oil (Eumulgin® HRE 40 or 60, alkoxylated with 40 or 60 moles of ethylene oxide) , Henkel KGaA) and / or 2-hydroxy fatty alcohol ethoxylates (Eumulgin® L, Henkel KGaA).
  • the amount of the perfume solubilizers in the agents according to the invention is generally between 0 and 10, preferably between 1 and 7% by weight.
  • the agents according to the invention may contain, for example, alkanolamines, polyols such as ethylene glycol, propylene glycol, 1,2 glycerol and other mono- and polyhydric alcohols, and alkylbenzenesulfonates with 1 to 3 carbon atoms in the alkyl radical.
  • alkanolamines polyols such as ethylene glycol, propylene glycol, 1,2 glycerol and other mono- and polyhydric alcohols
  • alkylbenzenesulfonates with 1 to 3 carbon atoms in the alkyl radical.
  • the group of lower alcohols, particularly ethanol, is particularly preferred.
  • the content of the solvents depends on the type and amount of the constituents to be dissolved and is generally in the range from 0.5 to 5% by weight.
  • the preferably water-soluble dyes are contained either for the coloring of the agent or for the coloring of the liquid surrounding the container.
  • the content of water-soluble dyes is preferably below 1% by weight and serves to improve the appearance of the product. If an additional color signal is desired during the flushing-in process, the content of water-soluble dyes can be up to 5% by weight. Examples
  • Table 2 shows further toilet gel toilet stone formulations that have an optimized ratio of surfactants to geraniol, the co-emulsifiers and perfume oil. The transparent area of these microemulsions is thereby achieved. The result is clear, gel-like formulations as shown in Examples 7 to 9.
