  • the pleasant feeling of freshness of the treated object disappears after a short time.
  • Fragrances in the form of fragrance pastilles 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.
  • Such scent pastilles are usually made from melt dispersions, the main component of which is a water-soluble or water-dispersible carrier material with a suitable melting point.
  • a suitable melting point e.g., a water-soluble or water-dispersible carrier material with a suitable melting point.
  • solids can also be added to such melt dispersions in order, for example, to influence the viscosity of the dispersion to be processed.
  • the production of the pastilles requires the continuous supply of such a melt dispersion.
  • the melt dispersion is naturally provided at temperatures above room temperature, the absolute temperature of the melt dispersion being determined by the chemical
  • the nature of the carrier material is determined as well as by the further course of the process, for example the use of additional heating or cooling elements provided or not provided in the course of the process.
  • the elevated temperature of the melt dispersion can affect the chemical integrity of the active substances and auxiliaries used and/or the physical integrity of the substance system used, for example its storage stability.
  • this object was achieved by a method which comprises at least three separate, successive method steps, so that an uninterrupted production process is provided.
  • the present invention is directed to a fusible body made by a method as described herein.
  • the present invention also relates to the use of the melting bodies, produced by a process as described herein, as textile care agents, preferably scenting agents and/or fabric softeners, for scenting and/or conditioning textile fabrics.
  • the present invention further relates to a detergent or cleaning agent, comprising a melt body, produced by a method as described herein.
  • Melt bodies designates bodies that are non-porous, meltable, water-soluble or water-dispersible under standard conditions (20° C., 1013 mbar) as solids and can be obtained by solidification and reshaping of the melts described herein.
  • the melting bodies can have any shape.
  • the shaping takes place in particular in step iii) of the method described. Solid, particulate are preferred
  • Shapes such as essentially spherical, figurative, scaly, cuboid, cylindrical, conical, spherical cap or lens, hemispherical, disc or needle-shaped melted bodies.
  • the melted bodies can have a figured configuration resembling a gummy bear. Due to their assembly properties and their performance profile, hemispherical melting bodies are particularly preferred.
  • Preferred melted bodies have a maximum diameter of between 4 and 15 mm, preferably between 5 and 10 mm, in any spatial direction. Particularly preferred melted bodies are characterized by a maximum diameter of 2 to 8 mm, particularly preferably 4 to 6 mm. On the one hand, such melted bodies are particularly readily water-soluble and, on the other hand, have a size that is visually appealing to the consumer.
  • 100% hemispherical (hemispherical) particles are characterized by a height to diameter ratio of 0.5.
  • those melted bodies which have a height-to-diameter ratio of 0.25 to 0.49 are also referred to as hemispherical.

  • 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 nature of the agent/compound and not to the absolute number of molecules. "At least one fragrance” therefore means that at least one type of fragrance is detected, but it can also contain 2 or more different types of fragrance.
  • the present invention relates to a manufacturing method for melted bodies, such as scented pastilles, in which a melted dispersion is produced in an uninterrupted process sequence and shaped in a final step.
  • the method as described here is characterized in that product changes, i.e. changing the composition of the melt dispersion, for example by using a different fragrance and/or color component, are possible without great effort, and it is also possible to largely avoid the accumulation of salable product quantities.
  • Another advantage of the method as described here is that the temperature-sensitive aesthetics incorporated into the melt dispersion to be produced has a short residence time at elevated temperatures (corresponding to the melting temperature of the respective carrier material) compared to production methods known in the prior art, which lozenges produced by the process as described herein show an improved color effect and/or an improved fragrancing upon their use.
  • a first object of the present invention is therefore a method for the production of melted bodies.
  • the method comprises the steps described below:
  • a perfume-free melt dispersion comprising at least one water-soluble or water-dispersible carrier material and at least one solid is produced in a first container.
  • the water-soluble or water-dispersible molten carrier material used has a melting point of >30°C, preferably >40°C and in particular >50°C.
  • Containers suitable for this purpose are generally known to those skilled in the art. However, a prerequisite for the applicability in a method as described here is that the container enables thorough mixing of the components of the melt dispersion to be produced in step i) and also comprises at least one adjustable opening through which the components of the melt dispersion to be produced in step i) in can be introduced into the container, and additionally at least one further adjustable opening through which the melt dispersion produced in step i) can be discharged from the container. Inlet and/or outlet flow can be volume-controlled via these openings.
  • the first container can be a mixing unit, for example.
  • the components of the melt are heated to a temperature above the melting point of the carrier material, preferably to a temperature above 40°C, more preferably above 50°C.
  • the carrier material can already be supplied in molten form and mixed with the at least one solid in the first container.
  • the transfer of the melt dispersion from the first container to the subsequent container takes place by means of pressure, so that the melt dispersion is pumped/pressed from the first container into the subsequent container. Pumping out the melt in this way offers the advantage that a largely complete, rapid transfer of the melt from one container to the next is ensured, so that as little residual material as possible, which remains as a residue in the respective outlet container, is lost.
  • the transfer of the melt dispersion from the first to the subsequent container or from the subsequent container for reshaping can also take place directly by means of suitable mixing units.
  • the carrier material can be melted in an additional container upstream of the first container.
  • the carrier material is basically melted by heating it to a temperature that is no more than 20° C. above the melting point of the carrier material. This also applies if the carrier material is melted in the first container already described. The melting can be carried out using all customary methods and devices known to those skilled in the art.
  • the carrier material melted in this way can then, in a step i) of the method preceding method step a), as described herein, be transferred to the first container in order to produce the melt dispersion according to step i).
  • the first container additionally comprises at least one adjustable opening which allows the introduction of a carrier material so melted.
  • the method described herein is accordingly characterized in that the carrier material is melted in a step a) preceding step i).
  • the individual flows can optionally be controlled by means of flow rate measurement of the individual metering streams, i.e. the melt, the fragrance stream and, if necessary, other streams will. This can also be used, for example, to set the proportions of the individual components.
  • the method according to the invention is preferably characterized in that the melt dispersion produced in step i) is transferred from the first container directly into the subsequent container.
  • the manufacturing method according to the invention is a sequential process sequence.
  • a process sequence as described herein can be continuous or as Batch processes take place, with a continuous process being preferred.
  • the continuous process management makes it possible to change the amount or chemical nature of the aesthetic agent used during operation, for example to stop the supply of fragrance in step ii) and to switch production to an alternative process product.
  • Due to the late dosing of the esthetic in step ii) its residues only have to be flushed out of one part of the production system (the part of the production system downstream of the dosing point for the esthetic) in the event of such a change by the subsequent melt dispersion.
  • the corresponding forerun which contains an undesired mixture of several esthetics or an incorrect concentration of the desired esthetic, can be discarded or can be recycled as waste material (in step i) or ii).
  • an advantage of the method as described here is that production changes are made possible without great effort. Due to the sequential process flow, the components to be added in the individual process steps, i.e. carrier material, solid, dye, fragrance and any other ingredients, can be exchanged for alternatives as far as possible separately from one another without the entire manufacturing process having to come to a standstill. In addition, the accumulation of large quantities of unsuitable product quantities can be avoided in this way. If, for example, a fragrance and/or colorant is to be changed, the supply of the fragrance and/or colorant is first stopped and the melt dispersion produced in step i) continues to be transferred from the first container to the second container and from there forwarded for forming.
  • the system is, so to speak, “rinsed” with the fragrance-free and/or dye-free melt and residual fragrance and/or dye is removed.
  • the waste obtained in this way can later be fed back into the process when the same fragrance and/or colorant is used again.
  • Another colorant and/or fragrance can then be added, with the forerun being discarded or returned to the process as waste material. Since melt is produced continuously, the fragrance and/or colorant is changed during the ongoing process, so to speak, and the amount of waste is comparatively small.
  • the method described herein is characterized in that waste material obtained after step ii) is returned to step i) or ii), preferably to step i).
  • the melt dispersion produced in step i) is mixed with at least one aesthetic agent outside the first container.
  • Step ii) is preferably carried out either (1) in a container downstream of the first container or (2) directly in the outflow stream emerging from the first container.
  • the melt dispersion is transferred to a subsequent container and in this container with at least mixed with an aesthetic; or (2) the at least one aesthetic is continuously mixed into the effluent stream of the first container
  • the admixing of the esthetic into the outflow stream of the first container can be implemented, for example, by providing the pipeline through which the melt dispersion is discharged from the first container with a supply line for the esthetic.
  • the first and subsequent containers are in communication with each other.
  • the melt dispersion produced in the first container is transferred to the subsequent container via this connection.
  • Downstream or “subsequent” as used in this context means that the container in question is downstream of the first container, i.e. the volume flow from the first container reaches this subsequent container at a later point in time in the process.
  • the volume flow emerging from the first container has previously passed through other, intermediate containers.
  • the container comprises at least one adjustable opening through which the melt dispersion produced in step i) can be introduced into the container, at least one further adjustable opening through which the esthetic (and any other components) can be introduced into the container, and in addition, at least one adjustable opening through which the melt dispersion produced in step ii) can be discharged from the container.
  • This container can also be a suitable mixing unit, such as a static mixer, for example.
  • the mixing can also take place by continuously admixing the at least one aesthetic agent into the outflow stream emerging from the first container, i.e. without the need for a separate container.
  • the opening through which the at least one aesthetic agent is introduced into the melt dispersion can preferably be regulated.
  • Aesthetics designates an active ingredient or auxiliary which is temperature-sensitive at the temperature used to produce the melt dispersion in step i), ie chemically or physically disintegrates at this temperature.
  • Aesthetics refers in particular to an active ingredient or auxiliary whose use in the melting bodies can be perceived by the consumer's senses.
  • the group of aesthetics includes the fragrances and dyes.
  • the fragrance is preferably used in liquid form, for example as a perfume oil, a solution in a suitable solvent or as a suspension of perfume capsules in a typically aqueous solvent.
  • "Liquid” as used in this context means liquid under the conditions of use, preferably liquid at 20°C.

For example, via the above-mentioned opening, which enables the melt dispersion produced in step ii) to be discharged from the downstream container, the melt produced is fed to the forming process.
  • the melt obtained after step ii) can be shaped using customary shaping methods. Suitable shaping methods are known to those skilled in the art and involve cooling the melt to a temperature below the melting temperature of the carrier material, so that the melt solidifies and thereby/then acquires its final shape.
