Abstract
A surface treatment composition comprising from about 6% to about 20%, by weight of the composition, of cationic polymer; from about 6% to about 40%, by weight of the composition, of anionic surfactant; and from about 4% to about 15%, by weight of the composition, of a shielding salt, wherein the weight ratio of anionic surfactant to cationic polymer is between about 0.5:1 and about 4:1. The shielding salt is defined by having a molecular weight of from about 25 to about 500 and being incapable of lowering the surface tension of water below 50 mN/m when added to water at concentrations of up to 0.01M.
