    Abstract: A pre-loaded cleaning substrate, and related systems and methods for picking up particles with an aspect ratio (L/D) greater than 300 (e.g., hair), or greater than 1200 (e.g., particularly long hairs). The substrate (e.g., a nonwoven) may include only a single layer of material. The pre-loaded substrate is loaded (e.g., during manufacture) with a cleaning composition. The fibers of the substrate may have an average diameter less than 15 μm, the substrate may have an air permeability of 35 ft3/min to 75 ft3/min, and the liquid cleaning composition may have a surface tension of less than about 50 dynes/cm. Together, the combination of the particular substrate and cleaning composition may facilitate markedly improved ability to pick up high L/D aspect ratio particle debris (e.g., such as hair), while retaining such particles (e.g., providing hair retention index values of at least 20).

    Abstract: The present invention relates to aqueous compositions of associative polyelectrolyte complexes (PECs), optionally containing surfactants, biocidal agents and/or oxidants, which can provide 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 where the one polyelectrolyte present in molar excess is added in the form of a first aqueous solution during a mixing step to a second aqueous solution comprising the oppositely charged polyelectrolyte present in molar deficiency. Also provided are means to form stable associative polyelectrolyte complexes in aqueous solutions having R values from about 0.10 to 20, including near stoichiometric R values approaching 1, being the ratio of charged groups present on the component polyelectrolytes employed.

    Abstract: 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 repellency, 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.
