  • Patent number: 11737458
    Abstract: A fibrous substrate for the removal of Gram negative bacteria (Escherichia coli) from a surface is provided. The fibrous substrate includes a capturing agent, and the affinity of capturing for the Gram negative bacteria allows the fibrous substrate to capture the Gram negative bacteria, thereby removing the Gram negative bacteria from the surface and also inhibiting the spread of the Gram negative bacteria to other surfaces that may contact the fibrous substrate. Of particular advantage, the presence of the capturing agent on the fibrous substrate may help protect against the spread or infection of pathogens without the use of chemicals, such as antiseptics or antibiotics.

  • Patent number: 10292916
    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/Dimethylaminoethylmethacrylate/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: 9826876
    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.
