Definitions

• the invention relates to textile treatment agents based on condensation products of carboxylic acids or carboxylic acid derivatives with polyamines, which are particularly well dispersible in water.
• the invention further relates to a method for producing the textile treatment agents and their use.
• textile treatment agents are understood to mean products which can be used in agents for finishing fibers and yarns, in detergents and in post-treatment agents for washed textiles.
• German patent 19 22 046 describes detergents containing fatty acid condensation products which contain fatty acid partial glycerides which have a dispersing action; German patent specification 19 22 047 also describes these fatty acid condensation products as textile softeners for, in particular, liquid laundry aftertreatment agents. These and similar textile treatment agents can be dispersed in water by heating the water and usually using high shear forces, or by dispersing the condensation product, which has still been melted, in water. Because of the effort required, the manufacturer usually carries out the dispersion and delivers the dispersions to the user, which is associated with the transport of considerable amounts of water.
