The present invention relates to aqueous compositions of associative polyelectrolyte complexes (PECs), optionally containing surfactants, biocidal agents and/or oxidants, which can provide a cleaning benefit and surface protection to treated articles including reduced soiling tendency, reduced cleaning effort and improved soil repellancy, as well as providing bacteriostatic properties to treated surfaces that thereby gain resistance to water, environmental exposure and microbial challenge. Treatment means and compositions are provided that employ associative polyelectrolyte complexes formed by combining a water soluble cationic first polyelectrolyte with a water soluble second polyelectrolyte bearing groups of opposite charge to the first polyelectrolyte under suitable mixing conditions and at least one oxidant selected from the group: alkaline metal salts and/or alkaline earth metal salts of hypochlorous acid, hypochlorous acid, solubilized chlorine, any source of free chlorine, acidic sodium chlorite, active chlorine generating compound and any combinations or mixtures thereof. Also provided are means to form stable associative polyelectrolyte complexes with at least one oxidant in aqueous solutions having R values from about 0.10 to 20.

Devices and methods for immobilizing micrometer sized liquid domains onto a chemically functionalized substrate surface are disclosed. A multifunctional polymer is adsorbed at the surface interface of the liquid microdomains, and the liquid microdomains are immobilized by covalent bonding or non-covalent forces such as electrostatic attraction between the adsorbed multifunctional polymer and the functionalized substrate surface.

Immobilization of droplets of liquid crystals on surfaces

A water soluble strip that includes a carrier film that include water soluble polymer, one or more actives and one or more agents such as heat forming agent and/or degrading accelerator. The water soluble strip can optionally include other additives. The actives includes antimicrobial agent, cleaning agent and/or surfactant. The water soluble strip can include other materials. The heat forming agent and/or degrading accelerator, when used, are designed facilitate in degrading or dissolving the water soluble strip and/or increase the activity of the one or more actives. The water soluble film can be used for a variety of applications such as a hard surface cleaning strip, dishwashing strip, laundry cleaning strip, stop removing strip, drain unclogging strip, toilet bowl cleaning strip and the like. The water soluble strip eliminates the need to purchase and store numerous containers and/or heavy containers of cleaner that take up large amounts of shelf space.
