1. An aqueous composition comprising:

  • (a) water;

    (b) a water soluble cationic first polyelectrolyte comprising at least one of a homopolymer or a copolymer of a diallyl dimethyl ammonium chloride monomer;

    (c) 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;

    alginic acid, alginate salts, xanthates, scleroglucans, carrageenans, carboxymethyl cellulose and its derivatives or pectins and its derivatives;

    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.
