  • Publication number: 20170224596
    Abstract: The present disclosure is directed to alcohol-based anti-adherent compositions that do not adhere to or attract Gram-negative and Gram-positive bacteria once it is applied to a surface and dried. The composition may include as anti-adherent agents, hydrophilic film-formers such as cellulosics, gums, acrylates, nonionic polymers, and anionic polymers. Examples of anti-adherent agents include Hydroxypropyl methylcellulose, Cellulose gum, Acacia Senegal Gum; Polyacrylate Crosspolymer-11, VP/Dimethyl-aminoethylmethacrylate/Polycarbamyl Polyglycol Ester; Acrylates/Vinyl Neodecanoate Crosspolymer, hydroxypropyl methylcellulose, Hydroxypropylcellulose, Methylcellulose, Propylene Glycol Alginate, Polyacrylate Crosspolymer-6, VP/Polycarbamyl Polyglycol Ester, Acrylates/Steareth-20 Methacrylate Copolymer; Acrylates Copolymer, and any combination thereof. The anti-adherent may be applied to surfaces using a vehicle such as a wipe.

  • Patent number: 9289520
    Abstract: A system for removing microorganisms from a surface is described. The system includes a conducting member, a voltage source, and an electrostatic field controller. The conducing member includes a nonwoven material incorporating conductive fibers. The controller is electrically connected to the conducting member and is configured to apply a DC voltage of about 15 volts or less to the conducting member via the voltage source. The surface to be contacted can include any surface present in households, food industry facilities, medical facilities, etc. Such surfaces can include tables, countertops, walls, cabinets, doors, door handles, door knobs, etc. The system can also be used to treat devices used in the aforementioned environments, such as food preparation equipment, medical devices, household appliances, etc. The system can reduce the amount of microorganisms on the surface by at least about 1 log (90%) without the use of chemicals, high voltages, or long exposure times.

  • Publication number: 20150089755
    Abstract: A cleaning article includes a cleaning article sheet comprising a fabric substrate, wherein the fabric substrate includes pores therein, and wherein the fabric substrate has a background moisture percentage by weight, and liquid water disposed substantially and disconnectedly within the pores, wherein the liquid water is at moisture percentage by weight that is 5 to 150 percentage points higher than the background moisture percentage. The nonwoven substrate can include pores formed between and/or within the fibers and can have a background moisture percentage by weight. The substrate can include a treatment to increase the dielectric constant from the dielectric constant of the substrate without the treatment. The moisture of the article can be configured to exhibit a dielectric constant of at least 50% and up to 600% higher than the dielectric constant of the same article with only background moisture.
