Abstract (en)

[origin: WO9503384A1] It has been discovered that aqueous dispersions of cationic textile softening compounds of the type of the quaternary ammonium compounds have a particularly stable viscosity when the rheological data correspond to the formula lg y = - k . lg tan o + A, in which y stands for the viscosity and tan o for the ratio (G"/G') between the loss module G" and the storage module G'. A process is thus disclosed for producing aqueous textile softener dispersions with a stable viscosity set in the range given by the formula by known influencing quantities, for example the intensity and the duration of the shearing process.
