1. An aqueous composition comprising:

  • (a) water;

    (b) citric acid;

    (c) a water soluble cationic first polyelectrolyte comprising at least one of a chitosan, synthetically produced B-1,4-poly-D-glucosamines and derivatives thereof, cationic guar, hydroxypropyl guar or starch bearing cationic charges added by chemical quaternization;

    (d) a water soluble anionic second polyelectrolyte comprising at least one of a homopolymer or a copolymer comprising at least one of the following anionic monomers;

    acrylic acid, methacrylic acid, maleic acid, maleic anhydride, itaconic acid, styrene sulfonic acid, or acrylamide propane sulfonic acid;

    wherein R, the molar ratio of charged groups present on said first polyelectrolyte to oppositely charged groups present on said second polyelectrolyte is between 0.10 to 20;

    wherein the first polyelectrolyte and the second polyelectrolyte are not block copolymers.
