1. has been replaced as follows:

  • (a) a water-soluble first polyelectrolyte bearing a net cationic charge or capable of developing a net cationic charge wherein said first polyelectrolyte is a poly(diallyldimethyl ammonium chloride) homopolymer;

    (b) about 0.001% to 0.19% by weight of a water-soluble second polyelectrolyte bearing a net anionic charge or capable of developing a net anionic charge wherein said second polyelectrolyte comprises at least one of poly(acrylic acid), a copolymer of acrylic acid and maleic acid, a copolymer of acrylic acid and styrene, a copolymer of styrene sulfonic acid and maleic acid, or mixtures thereof;

    (c) an oxidant;

    (d) wherein the composition is free of precipitates, synthetic block copolymers, silicone copolymers, cross-linked poly(acrylic) and cross-linked water-soluble polyelectrolyte;

    (e) wherein the composition has a viscosity of less than about 1,000centipoise;

    (f) wherein upon dilution, the concentrate composition forms a polyelectrolyte complex from the first polyelectrolyte and the second polyelectrolyte; and

    (g) wherein R, the molar ratio of charged groups present on said first polyelectrolyte to oppositely charged groups present on said second polyelectrolyte, is from about 0.1 to 20.
