Definitions

  • the present invention relates to a method for applying fragrances on textile goods in a washing machine.
  • DE 39 11 363 describes a process for producing fragrance-containing washing or rinsing liquors, in which a fragrance in the form of a capsule or a tablet is added to the washing or rinsing liquor.
  • the capsules contain the fragrance together with an emulsifier in liquid form, while the tablets also contain fillers and carriers, for example sodium aluminum silicates or cyclodextrins.
  • the tablets or capsules have a volume of more than 1 cm 3 and contain at least 1 g of fragrance. Tablets or capsules with more than 2.5 g of fragrance and a volume of at least 5 cm 3 are preferred.

At the same time they are stable in storage and can be stored without additional precautions become. Moldings can also be produced in this way a usual level of perfume oils for detergents and cleaning agents 1 and 3 wt .-% have.
  • Perfume oils are usually volatile and could therefore already be exposed to microwave radiation evaporate. Should have higher proportions of volatile liquid substances a two-component system is therefore used from a component made with microwave technology and one the components containing sensitive liquid substances are described.
