  • the consumer When using detergents or cleaning agents, the consumer expects not only long-lasting olfactory performance after using the product on the surface, e.g. on the textile, but also a space-filling perfume effect during or after using a product.
  • This can, for example, be a room-filling effect when drying textiles on the line, when opening the washing machine after the wash cycle or the room-filling effect after cleaning floor surfaces.
  • This room-filling (perfume) effect is also known as the blooming effect and is defined by an improved perception and intensity of perfumes in the room during or after the use of products that contain this perfume.

It is preferred if at least one layer of the water-soluble coating comprises a polyvinyl alcohol whose degree of hydrolysis is 70 to 100 mol %, preferably 80 to 90 mol %, particularly preferably 81 to 89 mol % and in particular 82 to 88 mol %.
