摘要:
A material substrate having at least part of a surface treated with an antimicrobial composition is described. The antimicrobial composition exhibits at least a 3 log10 CFU reduction within a period of about 30 minutes after contact with various species of a broad spectrum of microorganisms. The substrate can be a nonwoven material that has good fluid barrier properties, which can be used in protective garments and sheets. Methods for manufacturing and imparting the antimicrobial treatment to the substrate are also provided.
摘要:
An antimicrobial composition that involves a synergistic mixture in terms of active agents, of a primary antimicrobial agent, such as polyhexamethylene biguanide (PHMB), a secondary antimicrobial agent, and optionally an organic acid against various kinds of microbes is described. Various additional processing aids, such as alcohols and surfactants, may also be incorporated within the mixture. The composition allows one to use a significantly less concentration of individual constituent antimicrobial agents to achieve the same or a better degree of antimicrobial efficacy. The antimicrobial composition can be applied to the surface of almost any kind of substrate material, and can achieve a killing-efficacy of about 3 Log10 reduction in microbes within 30 minutes under ambient conditions.
摘要:
A synergistic antimicrobial composition containing at least two kinds of antimicrobial agents, including poly-hexamethylene biguanide (PHMB), stably associated to a material substrate is described. The substrate can take the forms of an anti-infection face mask, medical devices, or surgical instruments.

A face mask for reducing the amount of microbes to which a wearer is exposed is provided. The face mask includes a body portion that has an outer layer that has been treated with a germicidal agent in an effective amount. The layer may be a nonwoven fabric like a spunbond, meltblown or coform layer and may be a laminate of such layers. The face mask having such a germicidal treatment can result in a reduction in microbial activity as compared to another face mask, identical but for the germicidal agent.

A germicidal surface-covering assembly that includes at least two different donnable or drapable garments. Each garment defines at least one treated surface that is susceptible to pathogen contamination in a physical contamination event when used as intended in an environment subject to contamination (e.g., a clinical environment, a laboratory or a workplace). Each treated surface is adapted to provide a time-dependent reduction in the number of pathogens available at that treated surface after a physical contamination event, such that at least a predetermined time after a physical contamination event at a first location on a first treated surface of a first garment, a first physical contact between the first location on the first treated surface and a second location on a second treated surface of a second garment results fewer viable pathogens on the second treated surface as compared to an untreated control. Moreover, at least a predetermined time after the first physical contact, a second physical contact between the second location on the second treated surface and a third location on a third treated surface of a third garment results in fewer viable pathogens on the third treated surface as compared to an untreated control.
摘要:
An oxidizing antimicrobial treatment and products containing such treatment are described. The treatment involve, in part, preparing a substrate to accept an attachment of charged moieties, and a number of stabilized peroxide compounds on at least part of a surface of said substrate. When microbes, such as bacteria, having a net charge opposite to that of the charged moieties come in close proximity to the treated substrate surface, peroxide molecules from the substrate are activated and released to kill the microbes.

The present invention relates to a decal and method for treating a surface. The decal includes a web and an agent for treating the surface. The decal further includes a bonding material that attaches the decal to the surface. In some embodiments, the agent may be attached to the web while in other embodiments the agent may form part of the web. In one embodiment, the agent includes a composition formed of Urea HP and boric acid. In another embodiment, the agent includes a composition formed of polyhexamethylene biguanide and boric acid. In still another embodiment, the agent includes a composition formed of Urea HP and polyhexamethylene biguanide. In yet another embodiment, the agent includes a composition formed of polyhexamethylene biguanide and benzoic acid. In another embodiment, the agent includes a composition formed of polyhexamethylene biguanide and propionic acid.
摘要:
Cleansing systems and methods are disclosed for improving the cleaning of skin. The cleansing systems comprise a first product comprising an anti-adherent formulation and a second product comprising a cationic compound capable of binding contaminants located on the skin. The first product is wiped across the skin of a user to introduce a film of the anti-adherent formulation onto the surface of the skin. This film reduces the amount of contaminant that is retained on the skin. The second product is wiped across the skin of a user to further dislodge and remove contaminants from the skin. The cleansing systems result in cleaner, healthier skin.
摘要:
The present invention provides a topical composition for application to the perianal and/or labial areas of the skin which helps prevent viscoelastic fluids, such as menses and feces, from attaching to the skin and aids in the reducing the viscoelastic properties of the fluid so that the fluid can flow into absorbent articles. The composition contains at least one viscoelastant material and at least one an anti-adherent material. the composition may be applied with a wipe, including mitts and gloves, a solid stick composition, an aerosol dispenser, a pump spray, a trigger spray, a squeeze bottle, as a foam, as a cream, as an ointment, as a salve, as a gel, as a wash or as a lotion. In addition, absorbent articles, such as pads or pants, diapers and the like may also be used as a means to transfer the composition to the skin.
