Definitions

  • the present invention relates to a solid, particulate composition
  • a solid, particulate composition comprising at least one water-soluble carrier material and at least one fragrance
  • the carrier material being a water-containing salt (hydrate) whose water vapor partial pressure is equal to H 2 O at a certain temperature in the range from 30 to 100 ° C -Partial pressure of the saturated solution of this salt corresponds, so that the salt melts in its own crystal water at this temperature.
  • the composition is characterized by the fact that it has significantly improved water solubility compared to known polyethylene glycol-based compositions.
  • the invention further relates to methods for producing the solid composition, as well as a detergent or cleaning agent which contains the solid composition.
  • the present invention also relates to the use of such a detergent or cleaning agent for cleaning textiles or hard surfaces and corresponding methods for cleaning textiles or hard surfaces using such a detergent or cleaning agent.
  • the consumer When using detergents and cleaning agents, the consumer not only aims to wash, clean or care for the objects to be treated, but he also wants the treated objects, such as textiles, to be cleaned after treatment, for example the laundry smells pleasant. For this reason in particular, most commercially available detergents and cleaning agents contain fragrances.
  • Fragrances are often used in the form of fragrance particles either as an integral part of a detergent or cleaning agent, or dosed into the washing drum in separate form directly at the beginning of a wash cycle. In this way, the consumer can control the scent of the laundry to be washed through individual dosage.
  • the main component of such fragrance pastilles known in the art is typically a water-soluble or at least water-dispersible carrier polymer, such as polyethylene glycol (PEG), which serves as a vehicle for the integrated fragrances and which is more or less completely dissolved in the washing liquor during the waxing process dissolves in order to release the fragrances it contains and, if necessary, other components into the washing liquor.
  • PEG polyethylene glycol
  • a melt is produced from the carrier polymer, which contains the remaining ingredients or these are then added, and the resulting melt is then fed to a shaping process, during which it cools, solidifies and takes on the desired shape.
  • EP1600151 A1 relates to perfume particles comprising a perfume, a carrier material and a water-insoluble silicate, the particles being obtainable by spraying the perfume onto the carrier material and then adding the powdered silica during mixing.
  • DE 10 2012 218 690 A1 describes a solid, textile-care composition
  • a solid, textile-care composition comprising a water-soluble particulate carrier, a diol liquid at 23 ° C, a textile-care compound and a perfume, the water-soluble carrier being at least partially loaded with the diol and the perfume.
  • EP1600151 A1 discloses perfume particles on a water-soluble carrier.
  • the known products have the disadvantage that the polymer materials used, in particular PEG, have a delayed solubility, which can lead to residues on the laundry or in the washing machine, especially with short wash cycles, low temperatures or other unfavorable conditions.
  • the object of the present invention was therefore to identify an alternative composition which shows a suitable processing range and at the same time has improved water solubility in the usual temperature ranges in which work is carried out.
  • the object was achieved according to the invention by a formulation for melted bodies which comprises a carrier material and one or more fragrances, the carrier material being a water-containing salt (hydrate) whose water vapor partial pressure at a certain temperature in the range from 30 to 100 ° C corresponds to H 2 O partial pressure of the saturated solution of this salt at the same temperature, so that the salt dissolves in its own crystal water at this temperature, a process which can be described phenomenologically as melting, but which thermodynamically is a dissolution process.
  • a formulation for melted bodies which comprises a carrier material and one or more fragrances, the carrier material being a water-containing salt (hydrate) whose water vapor partial pressure at a certain temperature in the range from 30 to 100 ° C corresponds to H 2 O partial pressure of the saturated solution of this salt at the same temperature, so that the salt dissolves in its own crystal water at this temperature, a process which can be described phenomenologically as melting, but which thermodynamically is a dissolution process.

In particular, this information refers 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 recorded, but 2 or more different types of fragrance can also be included.
  • 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.
  • the solid, particulate composition as described herein is prepared from a solution of the carrier material in the water/water of crystallization contained in the composition, the term “melt” also being used herein for such a solution in contrast to the established usage, to describe the state in which the carrier material dissolves in its own crystal water by splitting off water and thus forms a liquid.
  • the term “melt” as used herein therefore refers to the liquid state of the composition that arises when the temperature is exceeded at which the carrier material splits off water of crystallization and then dissolves in the water contained in the composition.
  • the corresponding dispersion, which disperses the (solid) substances described herein in the melt of the Contains carrier material is therefore also the subject of the invention.
  • the corresponding melt/melt dispersion from which it is available is always included. Since they do not differ in composition with the exception of the physical state, the terms are used synonymously herein.
