Abstract: Systems and methods for air sanitization. The system includes a device configured to create aerosolized droplets of an antimicrobial formulation with an average particle size sufficiently small so that the formulation provides at least a 3-log reduction against Staphylococcus aureus or another target microbe within 60 minutes. The antimicrobial formulation includes one or more organic acids (e.g., lactic acid) and optionally one or more diols (e.g., 1,2-hexanediol). Where both are included, the organic acid(s) and diol(s) may have a vapor pressure of at least 0.02 Pa. Where just the organic acid is included, the organic acid has a vapor pressure of at least 0.10 Pa. The formulation may further include a buffer, a surfactant, water, a fragrance, etc. The formulation may be delivered as an aerosol, using a pump sprayer, a mister, a nebulizer, a vaporizer, a cold fogger, a thermal fogger, an ultrasonic dispensing device, an electrostatic sprayer, etc.

Abstract: 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.

Abstract: 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.
