• the invention also relates to a method for producing the solid composition and a washing or cleaning agent which contains the solid composition.
• the present invention also relates to the use of such a washing or cleaning agent for cleaning textiles and corresponding methods for cleaning textiles using such a washing or cleaning agent.
• fragrances in the form of fragrance particles are either used as an integral component of a washing or cleaning agent, or are metered into the washing drum in a separate form at the beginning of a washing cycle. In this way, the consumer can control the scenting of the laundry to be washed through individual dosing.
• One form of supply that enables the separate dosage of fragrances is the fragrance lozenge.
• the main component of such fragrant lozenges 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 absorbed in the wash liquor during the course of the waxing process dissolves in order to release the contained fragrances and possibly other components into the wash liquor.

• 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 in the case of short wash cycles, low temperature or other unfavorable conditions.
• the scented lozenges described in the prior art generally have no additional function, that is to say, they are generally used exclusively for scenting.

• the solid, particulate composition as described herein is produced 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 use, to describe the state in which the carrier material dissolves in its own crystal water through the splitting off of water and thus forms a liquid.
• the term “melt”, as used herein, thus denotes the liquid state of the composition which 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.
