Definitions

• the invention relates to a refill portion of a fabric softener composition.
• the invention also relates to the production of the fabric softener composition from the refill portion and a process for producing the refill portion.
• Fabric softeners are added to the laundry in the last rinse cycle of the machine wash to prevent the "dry stiffness" effect that occurs when the laundry dries. Dry stiffness is caused by the formation of hydrogen bonds between the cellulose fibers. The cationic surfactants in the fabric softener penetrate the fibers or settle on the fiber surface, combine with the negative charges and thus weaken the interactions. The reduced stiffness of the laundry reduces the effort required for ironing and increases comfort.
• Fabric softeners are often low-concentration formulations that contain mostly water. Even the more concentrated formulations contain a very large amount of water.
• washing and cleaning agents for example, are offered in the most concentrated form possible and, in the case of fabric softeners, contain as little or no water as possible. This can significantly reduce the amount of packaging material. In addition, the weight and volume to be transported can be reduced in this way, which also leads to a saving of resources in the area of logistics.
• Some solid concentrated cleaning compositions are already known that are dissolved in water by the consumer, thus producing, for example, a ready-to-use cleaning solution for hard surfaces.
• compositions In order for fabric softener compositions to be used by the consumer and for the cationic surfactants to be effective, the compositions must be present as a stable, homogeneous mixture.
• the improved fragrance properties left on a textile by a fabric softener should also be retained with such a product.
• the consumer should not suffer any disadvantages in the fragrance properties of their textiles, both when the fragrance is released directly after washing and after the laundry has been stored or when it is in use.
• the object of the present invention was therefore to provide a solid, powdery, free-flowing softening composition containing at least quaternary ammonium compound and fragrance, which can be easily converted by the consumer at any time into a commercially dosable liquid fabric softener with known properties using a predetermined amount of drinking water.
• Sustainability aspects for refill formats, including through reduced packaging materials, should be met, as should the improved fragrance properties.
• solid compositions comprising a laundry softening esterquat compound and fragrance in the form of free perfume and perfume microcapsules are suitable for the production of liquid laundry softeners by the consumer and solve the above-mentioned problems.
• the fabric softening esterquat compound can be an esterquat compound commonly used in fabric softeners.

• R 1 is a C1-4 alkyl or hydroxyalkyl group or a C2-4 alkenyl group.
• L is an ester linker of the structure -OC(O)- or -C(O)-O-.
• n is selected from 0 to 4, e.g. 2 to 4.
• the counterion X- is preferably chloride, methyl sulfate or ethyl sulfate.

It is particularly preferred if the mass of perfume microcapsules used is greater than the mass of perfume oil used, in particular if the free perfume oil and perfume microcapsules are used in a ratio of 1:1.9 to 1:1.3.
• the amount of free perfume oil refers to the amount of free perfume oil that is used in the manufacture of the solid product as free perfume oil and not in the form of encapsulated perfume. Because the product is present as a solid, the perfume oil in the solid product is absorbed or adsorbed on or in a solid.
