  • the present invention is predicated on the discovery that the softening effects provided by the combination of a PEC compound and a clay carrier, such as bentonite, is materially enhanced when a polyphosphonate compound is contacted with the heated particulate clay carrier so as to be electrostatically bound thereto, thereby enhancing the substantivity of the molten PEC softener to the surface of the clay particles.
  • the sequence of addition is such that polyphosphonate is contacted with the clay particles prior to contact of the clay with the PEC softener in order to significantly enhance the softening benefit capable of being delivered by the resultant softening composition or article.
