Definitions

  • the present invention relates to a solid, particulate composition
  • a solid, particulate composition comprising at least one water-soluble carrier material, at least one rheology modifier and at least one fragrance
  • the carrier material being a water-containing salt (hydrate) whose water vapor partial pressure at a specific temperature is in the range from 30 to 100°C corresponds to the H 2 O partial pressure of the saturated solution of this salt, so that the salt melts in its own crystal water at this temperature.
  • the invention relates to methods for producing the solid composition and to a washing or cleaning agent that contains the solid composition.
  • the present invention also relates to the use of such a washing or cleaning agent for cleaning textiles or hard surfaces and corresponding methods for cleaning textiles or hard surfaces using such a washing or cleaning agent.
  • the DE19953503 A1 describes scented pearls containing derivatives of polysaccharides as carrier material.
  • DE102016219292 A1 discloses perfume-containing fusible bodies containing polyethylene glycol as carrier material.
  • 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, after treatment, for example after the laundry, smell pleasant. For this reason in particular, most commercially available detergents and cleaning agents contain fragrances.
  • Fragrances in the form of fragrance particles are often used either 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 wash cycle. In this way, the consumer can control the scent of the laundry to be washed through individual dosing.
  • the main component of such fragrance pastilles known in the prior 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 more or less completely dissolves in the washing liquor during the waxing process dissolves in order to release the fragrances contained and any other components in the wash liquor.
  • PEG polyethylene glycol
  • a melt is produced from the carrier polymer, which contains the other ingredients or these are then added, and the melt obtained is then fed to a shaping process during which it cools, solidifies and assumes the desired shape.
  • the known products have the disadvantage that the polymer materials used, in particular PEG, have a delayed solubility, which is particularly important for short wash cycles, low temperature or other unfavorable conditions can lead to residues on the laundry or in the washing machine.
  • 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, can be provided by using a water-containing salt ( hydrate) is used, the water vapor partial pressure of which at a certain temperature in the range from 30 to 100°C corresponds to the 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 is thermodynamically a solution process.
  • the use of sodium acetate trihydrate is particularly advantageous.
  • These specific carrier materials are preferably processed by means of a process during which the salts are prepared as melts and then dropped onto a cooling belt, for example using a nozzle, on which they solidify and assume a final geometric shape.
  • a process during which the salts are prepared as melts and then dropped onto a cooling belt, for example using a nozzle, on which they solidify and assume a final geometric shape.
  • the yield point is measured using a rotational rheometer (AR G2 from TA Instruments or a "Kinexus” from Malvern), using a plate-plate measuring system with a diameter of 40 mm and a plate spacing of 1.1 mm.
  • the yield point is determined in a step-flow procedure in which the shear stress is increased quasi-statically, i.e. while waiting for the equilibrium deformation or stationary flow, from the lowest possible value to a value above the yield point.
  • the deformation is plotted against the shear stress in a double logarithmic diagram. If there is a yield point, the curves obtained in this way show a characteristic kink. Below the kink, only elastic deformation takes place.
  • the slope of the curve in the double logarithmic representation is one. Above the kink, the slope of the curve increases abruptly and steady flow occurs. The shear stress value of the kink corresponds to the yield point. If the kink is not very sharp, the point of intersection of the tangents of the two curve sections can be used to determine the yield point. For liquids that do not have a yield point, the graph described above is usually curved to the right.
  • the at least one carrier material is used in an amount such that the resulting melted body, ie the scented pastille, contains from 30 to 95% by weight, preferably from 40 to 90% by weight, for example 45 to 90% by weight, based on the total weight of the fused body containing support material.
  • the solid, particulate composition as described herein is prepared from a solution of the carrier material in the water/crystal water contained in the composition, the term “melt” also being used here for such a solution, in contrast to the established usage, to describe the state in which the carrier material dissolves in its own water of crystallization due to the elimination of water and thus forms a liquid.
  • the term “melt”, as used herein, thus designates the liquid state of the composition, which occurs 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 contains the (solid) substances described herein dispersed in the melt of the carrier material is therefore also a subject of the invention. So when reference is made below to the solid, particulate composition, the corresponding melt/melt dispersion from which it can be obtained is always included. Since these do not differ in composition, with the exception of the physical state, the terms are used synonymously here.
  • fused body is used herein to describe the solid particles obtainable from the liquid composition upon cooling by solidification/transformation.
  • the main component of the particulate, solid composition as described herein is at least one water-soluble carrier material.
  • the at least one carrier material is characterized in that it is selected from water-containing salts whose water vapor partial pressure at a temperature in the range from 30 to 100° C. corresponds to the H 2 O partial pressure of the saturated solution of this salt at the same temperature.

  • a particularly suitable hydrate is sodium acetate trihydrate (Na(CH 3 COO).3H 2 O), since it dissolves in its own water of crystallization in the particularly preferred temperature range of 55 to 80° C., specifically at about 58° C.
  • the sodium acetate trihydrate can be used directly as such, but alternatively the use of anhydrous sodium acetate in combination with free water is also possible, the trihydrate then being formed in situ .

  • the solid particulate composition can be marketed or used alone or in combination with another preparation.
  • the solid particulate composition is part of a washing or cleaning agent.
  • a composition as described herein can be used, for example, in the wash cycle of a laundry cleaning process and thus transport the perfume to the laundry right at the start of the washing process. Furthermore, the composition is simpler and easier to handle than liquid compositions, since no droplets remain on the edge of the bottle, which lead to edges on the substrate or to unsightly deposits in the area of the closure when the bottle is subsequently stored. The same applies in the event accidental spillage of composition during dosing. The spilled amount can also be cleaned up more easily and cleanly.
