Definitions

  • the invention relates to a liquid fabric softening composition with trialkanolamine-based esterquat.
  • Fabric softeners are added to the laundry in the last rinse of the machine wash to prevent the effect of "dry drying” occurring during drying laundry.
  • the dry rigidity is due to the formation of hydrogen bonds between the cellulose fibers.
  • the cationic, softening compounds of the softener penetrate into the fiber or lie on the fiber surface, combine with the negative charges and weaken the interactions. Due to the reduced stiffness of the garment, the force required for ironing is reduced and the wearing comfort is increased.
