Definitions

  • the present invention relates to a continuous process for the production of perfume-containing melting bodies comprising at least one water-soluble or water-dispersible carrier polymer with a melting point> 30 ° C. and at least one fragrance, comprising the process steps described here and the perfume-containing melting bodies produced in this way.
  • Fragrances in the form of fragrance particles are often either used as an integral part of a washing or cleaning agent, or are metered into the washing drum in a separate form directly at the start of a washing cycle. In this way, the consumer can control the scenting of the laundry to be washed by individual dosing.
  • Fragrance particles of this type are usually provided in the form of perfume-containing melting bodies in a batch process.
  • Such perfume-containing moldings produced from melts require that the perfume is exposed to higher temperatures during manufacture.
  • the finished product melt is then transferred into a shaped body by means of cooling. Any production disruptions mean that the melt has to stay at higher temperatures for a longer period of time. This can lead to the breakdown of thermolabile components, such as some perfume components.
  • the melting of the ingredients of the shaped body, including the perfume results in the latter being exposed to unnecessarily long, high temperatures, which can also be disadvantageous for the reasons mentioned above.
  • the object of the present invention was therefore to overcome the problems mentioned above in the production of perfume-containing melting bodies.
  • the object was achieved according to the invention by a continuous process in which one or more constituents of the shaped body, i.e. usually the at least one carrier polymer, the fragrances are metered in continuously.
  • a continuous process in which one or more constituents of the shaped body, i.e. Usually the at least one carrier polymer is melted and the fragrances are metered in continuously to the melt.
  • melt is meant a composition that can be pumped, pumped and flowed.
  • the melt comprising the at least one water-soluble or water-dispersible carrier polymer, which according to the present invention is continuously conveyed, can be produced spatially decoupled from the conveyance.
  • At least one refers to 1 or more, for example 1, 2, 3, 4, 5, 6, 7, 8, 9 or more. In particular, this information relates to the type of agent / compound and not the absolute number of molecules. "At least one fragrance” therefore means that at least one type of fragrance is detected, but 2 or more different types of fragrances can also be contained.
  • the melting bodies obtained are solid at room temperature and temperatures up to 30 ° C., preferably up to 40 ° C.
  • the at least one carrier polymer is distinguished by the fact that it has a melting point of from 48 ° C. to 120 ° C., preferably from 48 ° C. to 80 ° C.
  • Water soluble as used herein means a solubility in water at 20 ° C of at least 1 g / L, preferably at least 10 g / L, more preferably at least 50 g / L.

  • a polyethylene glycol is characterized by a melting point in the range from 45 to 70 ° C., preferably 50 to 65 ° C., more preferably 50 to 60 ° C.
  • the at least one carrier polymer is contained in the melting body in an amount of 30 to 95% by weight, preferably 35 to 85% by weight, for example 40 to 80 or 40 to 78% by weight, based on the Total weight of the melting body
  • Another component of the melting body is at least one fragrance.
  • a fragrance is a chemical substance that stimulates the sense of smell. In order to stimulate the sense of smell, the chemical substance should be at least partially dispersible in the air, ie the fragrance should be at least slightly volatile at 25 ° C.
