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

The present invention is for an acidic cleaning composition which has excellent cleaning performance, low toxicity and good antimicrobial efficacy. The inventive acidic cleaning compositions are capable of sanitizing or disinfecting a variety of hard surfaces. The inventive acidic cleaning compositions can take a variety of forms, such as: disinfecting wipes, all-purpose disinfecting sprays, kitchen cleaners, bathroom cleaners, toilet cleaners, etc. The compositions may meet EPA DfE requirements, EPA category III or IV requirements, and/or be safe for use on food contact surfaces without rinsing. The compositions may include citric acid, an anionic surfactant, a non-volatile glycol solvent, a fatty acid, and water. The compositions may be free of other sanitizing acids, quaternary ammonium compounds, biguanides, peroxides, hypohalites, etc., and have a pH of less than 2.5. The composition may provide sanitization or disinfection against a target microbe within 5 minutes or less, or 4 minutes or less.

Acidic cleaning and disinfecting composition comprising citric acid, an anionic/APG surfactant mixture, and glycol ether solvent

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 ft/min to 75 ft/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).

Organic acid based antimicrobial formulations containing extremely low levels of surfactant

Peroxide treatment compositions for use in laundry capable of providing sanitization through the wash e.g., for use with a detergent, where a peroxide activator is stabilized without the presence of phosphorus-containing compounds (e.g., phosphorus-containing stabilizers), through use of a nonionic surfactant (e.g., alkoxylated alcohol) with a cloud point above 45° C. Use of a single nonionic surfactant, or a surfactant package that may include a small fraction (e.g., less than 0.5%) of sodium lauryl sulfate or another anionic surfactant has been found to be surprisingly effective at stabilizing the peroxide/activator combination, even where water content may be 85% or greater. The composition can have a pH of 5 or less (e.g., 3 to 4). The composition may be free of other anionic surfactants, cationic surfactants, zwitterionic surfactants, amphoteric surfactants, magnesium salts, borates and boric acid, hydroxides, chelating agents, various amine oxides, ethoxylated amines, and the like.

Stable activated peroxide sanitizing liquid compositions without added phosphorous compounds or cationic surfactants

Acidic cleaning and disinfecting compositions comprising a citric/methansulfonic acid mixture

Precursor polyelectrolyte complex compositions in dual chamber dispensing system

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.
