(57) A method of enhancing the rewettability of fabrics treated in a laundering operation
in which the fabrics are contacted with a mixture including a rinse cycle fabric softening
conditioning composition capable of producing on the fabrics a hydrophobic surface
and a hydrophobic cationic emulsion of a silicone polymer. Preferably, the fabric
softening conditioning composition includes a cationic compound selected from the
group consisting of quaternary ammonium salts and organic based compounds having Cāā
to Cāā hydrocarbon chain molecules of amines, esters, acids or amine oxides and the
silicone polymer is a highly branched and crosslinked polydimethylsiloxane.
