Abstract

A solid, particulate composition having at least one water-soluble carrier material, at least one fragrance and at least one rheology modifier, wherein the carrier material is a water-containing salt (hydrate) whose water vapor partial pressure at a specific temperature in the range from 30 to 100° C. corresponds to the H2O partial pressure of the saturated solution of this salt, such that the salt melts at this temperature in its own crystal water. The invention further relates to processes for producing the solid composition, and to a washing or cleaning product including the solid composition. In addition, the present invention also relates to the use of a washing or cleaning product of this kind for cleaning of textiles or hard surfaces, and corresponding methods of cleaning textiles or hard surfaces using a washing or cleaning product of this kind.
