A composition contains (A) a silicone component which is an aqueous oil-in-water microemulsion containing a polysiloxane stabilized in the microemulsion by a cationic surfactant, and (B) a inorganic salt or an organic salt. The polysiloxane in the cationic microemulsion has a particle diameter of less than about 100 nanometer, preferably less than about 40 nanometer. The polysiloxane is a polydimethylsiloxane or an amine functional polysiloxane, preferably prepared by emulsion polymerization. The composition preferably contains at least about twenty percent by weight of the salt.
