The invention relates to compositions and methods of treatment employing compositions comprising polyelectrolyte complexes. The compositions include a water-soluble first polyelectrolyte bearing a net cationic charge or capable of developing a net cationic charge and a water-soluble second polyelectrolyte bearing a net anionic charge or capable of developing a net anionic charge. The total polyelectrolyte concentration of the first solution is at least 110 millimolar. The composition is free of coacervates, precipitates, latex particles, synthetic block copolymers, silicone copolymers, cross-linked poly(acrylic) and cross-linked water-soluble polyelectrolyte. The composition may be a concentrate, to be diluted prior to use to treat a surface.

Precursor polyelectrolyte complexes compositions

Sanitizing and disinfecting compositions with relatively low levels of free available chlorine, with good effectiveness against microbes. The composition may include less than 0.5% by weight hypochlorite or other free available chlorine level, at least one nonionic or zwitterionic surfactant, with a pH from 8 to 12.5. The composition is characterized by an R value of greater than 0 (e.g., greater than 0.5, or equal to 1), where R is defined as the sum of the concentration of any nonionic, zwitterionic, and cationic surfactants divided by the total surfactant concentration (and total surfactant concentration may include any surfactant aids). The compositions may exhibit at least a 3-log reduction inorpopulation within 10 minutes (e.g., 4-6 minutes).
