Definitions

  • the present invention relates to a process for the preparation of spherical fragrance particles, the fragrance particles thus obtained, as well as their use for fragrancing objects, in particular textile fabrics.
  • the consumer In the use of detergents and cleaners, the consumer not only aims to wash, cleanse or care for the objects to be treated, but also desires that the treated objects, such as textiles, after treatment, for example after washing, smell pleasant. For this reason in particular, most commercially available detergents and cleaners contain fragrances. Most fragrances, however, are volatile. For this reason, when using conventional washing or cleaning agents after use, especially after washing, only a small proportion of the fragrance used remains on the treated object. As a result, often only a faint scent of the treated object, especially the laundry, goes out, which then already weaker after a short time. Thus, the pleasant feeling of freshness of the treated object disappears after a short time.
  • fragrances are used in the form of perfume particles either as an integral part of a washing or cleaning agent, or dosed directly into the washing drum at the beginning of a wash cycle in a separate form. In this way, the consumer can control the fragrance of the laundry to be washed by individual dosage.
