  • the washed textiles In addition to the removal of stains, impurities or unpleasant odors, it is also important for many consumers that the washed textiles have a pleasant odor after washing and / or drying. For this purpose, the textiles are often treated after the actual washing and cleaning process in a subsequent rinsing process with a fabric softener.
  • cationic fabric softening compounds having one or two long-chain alkyl groups in one molecule.
  • Commonly used cationic fabric softening compounds include, for example, so-called ester quats.
  • the object of the invention is therefore to further improve the functionality of systems for using a tumble dryer.
  • a system of perfumed composition and dispenser for multiple use in a dryer wherein the perfumed composition comprises a particulate carrier and a perfume, and the dispenser inside the device has a cavity formed by one or more walls for receiving the perfumed Composition and perforations in the wall / walls and wherein the dispenser on the outer surface has a recess which is at least partially filled with a wax, wherein the wax is delivered over several cycles of application to the treated textiles, characterized in that the Wax contains one or more ingredients selected from the group consisting of N, N'-ethylenebis fatty acid amides, quaternary ammonium compounds, glycerol esters and mixtures thereof, and wherein the wax has a melting point in the range of 80 to 110 ° C.

  • a perfumed composition with a particulate carrier containing an ethylene / vinyl acetate copolymer releases a nearly constant amount of perfume under heat in each application.
  • the amount of perfume in the perfumed composition is up to 40% by weight, preferably between 5 and 40% by weight.
  • the wax contains one or more ingredients selected from the group consisting of N, N'-ethylenebis fatty acid amides, quaternary ammonium compounds, glycerol esters, and mixtures thereof. Waxes with these ingredients have a sufficiently high melting point and a sufficiently high abrasion resistance and have not completely disappeared from the surface of the dispenser already after an application cycle.
