1. A treatment composition comprising:
(i) water;
(ii) at least one water-soluble associative polyelectrolyte complex comprising a water soluble cationic first polyelectrolyte; and a water soluble second polyelectrolyte bearing groups of opposite charge to said first polyelectrolyte; wherein the resulting water-soluble associative polyelectrolyte complex is non-precipitating in the treatment composition, 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 0.10 to 20;
(iii) wherein said cationic first polyelectrolyte and said second polyelectrolyte each comprise at least one of homopolymers, random copolymers, alternating copolymers, or mixtures thereof;
(iv) wherein neither said cationic first polyelectrolyte nor said second polyelectrolyte is a synthetic block copolymer;
(v) wherein the at least one polyelectrolyte complex is at a concentration of no more than about 100 mM with respect to a total concentration of charged groups present on the first polyelectrolyte and the second polyelectrolyte making up the at least one polyelectrolyte complex;
(vi) wherein the at least one associative polyelectrolyte complex has an average aggregate size in solution of less than about 500 nanometers; and
(vii) wherein film formation of the at least one water-soluble associative polyelectrolyte complex during use to treat a surface is self-limiting so as to not grow to macroscopic dimensions which would otherwise become visible to the eye, but instead maintaining a film thickness of less than about 500 nm.
