  • the invention relates to a process for the preparation of low-viscosity aqueous ester quat concentrates, in which aqueous solutions of quaternized di-fatty acid trialkanolamine ester salts are mixed with selected viscosity regulators.
  • the American patent US 23 40 881 describes aqueous dispersions of condensation products, Made from a hydroxyalkyl poly in and a fatty acid glyceride, which improve the lubricity and the softness of the textiles treated with it.
  • Esterquats are not only characterized by excellent anti-static and anti-static properties, but also have a surprisingly good biodegradability for cationic surfactants. It is disadvantageous, however, that aqueous esterquat concentrates behave dilutantly at low shear forces and are structurally viscous only when shear is strong. In practice, this means that the viscosity of aqueous ester quat concentrates increases by leaps and bounds when pumping, and conveying these products through pipelines is therefore extremely problematic.
  • the object of the invention was therefore to develop a new process for producing low-viscosity textile treatment agents which is free from the disadvantages described.

  • Textile treatment agents with a particularly low viscosity under shear can be produced by using quaternized di-fatty acid trialkanolamine ester salts of the formula (I) in which R ⁇ -CO is an acyl radical having 12 to 18 carbon atoms, Z is an ethylene group and / or X represents chloride or methosulfate.
