Abstract

Abstract 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 C12 to C18 hydrocarbon chain molecules of amines, esters, acids or amine oxides and the silicone polymer is a highly branched and crosslinked polydimethylsiloxane.
