  • a fragrance is a chemical substance that stimulates the sense of smell.
  • the chemical substance should be at least partially airborne, i.e. the fragrance should be at least slightly volatile at 25°C. If the fragrance is now very volatile, the odor intensity then quickly fades away. With a lower volatility, however, the odor impression is more lasting, i.e. it does not disappear as quickly.
  • the fragrance therefore has a melting point in the range from -100°C to 100°C, preferably from -80°C to 80°C, more preferably from -20°C to 50°C, in particular from - 30°C to 20°C.

  • the fragrance has a molecular weight of 40 to 700 g/mol, more preferably 60 to 400 g/mol.
  • fragrance The smell of a fragrance is perceived as pleasant by most people and often corresponds to the smell of, for example, blossoms, fruits, spices, bark, resin, leaves, grass, moss and roots. Fragrances can also be used to mask unpleasant odors or to provide a non-smelling substance with a desired smell.
  • Individual fragrance compounds for example synthetic products of the ester, ether, aldehyde, ketone, alcohol and hydrocarbon type, can be used as fragrances.
  • fragrance oils are preferably used, which together produce an appealing fragrance.
  • Such a mixture of fragrances can also be referred to as a perfume or perfume oil.
  • Perfume oils of this kind can also contain natural mixtures of fragrances, such as are obtainable from vegetable sources.
  • the fragrance is used in encapsulated form (fragrance capsules), in particular in microcapsules.
  • the entire fragrance can also be used in encapsulated form.
  • the microcapsules can be water-soluble and/or water-insoluble microcapsules.
  • melamine-urea-formaldehyde microcapsules, melamine-formaldehyde microcapsules, urea-formaldehyde microcapsules or starch microcapsules can be used.
  • Pro-fragrance refers to compounds that only release the actual fragrance after chemical conversion/cleavage, typically upon exposure to light or other environmental conditions such as pH, temperature, etc. Such compounds are often also referred to as fragrance storage substances or “pro-fragrance”.
  • composition of some preferred free-flowing detergent preparations can be found in the following tables (data in % by weight based on the total weight of the preparation, unless stated otherwise).
  • the detergent preparations are packaged with particular preference as detergent portion units in which the detergent preparation is completely enclosed by a water-soluble film.
  • the detergent preparations are preferably free from copolymers with hydrophobic side chains, in particular free from copolymers of acrylic acid with lauryl methacrylate.
