The present disclosure relates to a multilayer fabric media comprising a non-woven membrane of fibers comprising at least one polymer in combination with at least one photoreactive agent mounted on a woven or non-woven substrate and coated with a light transmissible protective layer, to methods of forming such multilayer fabric media, and to articles of manufacture made therewith.

Provided are foams and foamable formulations for the decontamination of surfaces, such as disinfection from COVID-19. The formulations can allow deposition of a uniform layer of foam on a given surface without spontaneous drainage of water and with near zero flowability. The foam can adhere to slanted surfaces and surfaces comprised of a variety of materials, including wood, glass, and stone, enabling safe and effective viral decontamination in a number of settings.

A composition for use as a hard surface cleaner, sanitizer and/or disinfectant is disclosed. The composition according to one embodiment comprises an arylsulfonic acid, a source of peroxide, an effective amount of a stabilizer and water. A method is provided of cleaning, disinfecting and/or sanitizing a hard surface, the method comprising providing the composition, providing a surface which requires cleaning and applying the composition onto the surface for a duration of time sufficiently long enough to destroy micro-organisms present on the surface.

Disclosed are methods and compounds useful for forming coatings applied to porous and non-porous surfaces to make the surface antimicrobial and to protect against contaminants. The coatings are formed from phenolic compounds present in a solvent either alone or in combination with other compounds, such as metallic salts.

A sterilization validation system and method are disclosed that ensure sterilization of packaging materials that contain certain sterilized items that have been sterilized in a cleanroom environment. In accordance with the disclosed subject matter, garments (or other items or materials) that are sterilized inside autoclave or breather bags may be secured within tote liners that ensure sterility of the exterior of the breather bags containing the garments. Not only is it possible to ensure a recipient that the garment is sterile, but it is also possible to verify that the outside of the breather bag itself is also sterile, since the breather bag will remain sterilized inside the tote liner during shipping.

A surface coating composition may include titanium dioxide optionally combined with copper oxide to permanently bind to any surface to create a long lasting, self-cleaning, deodorizing, and antimicrobial surface, and preparation method thereof. A method of continuous flow process to create anatase TiO.sub.2 crystals with particle sizes ranging from about 0.1 nm to about 200 nm, or further ranging from about 0.1 nm to about 20 nm in size.

Disclosed is a malodor control system that includes use of a malodor scavenger to sequester a malodor molecule to reduce and/or eliminate the noxious odor the malodor molecule generates. Some embodiments can include use of a substrate as a non-woven fabric sheet as a delivery system for the malodor scavenger. The substrate can include a polymer complexed with active ingredient to lock the active ingredient in place at a surface of the substrate via a binder so that the active ingredient is present at a predetermined activity level. After interacting with malodor molecules, at least some of the active ingredient migrates via passive diffusion to the substrate surface to maintain the predetermined activity level. Embodiments of the substrate are made from a blend of polyester and rayon, wherein rayon is made using viscose, allowing the substrate to be biodegradable and to handle an increased load of active ingredient.

Methods of the present invention comprise photoinactivation of catalase in combination with low-concentration peroxide solutions and/or ROS generating agents to provide antibacterial effects.

An apparatus for use in a method of decontaminating a device including a tray. A membrane permeable by a decontaminating fluid is positioned over the top of the tray to form an enclosed space. A lid is secured to the tray and the membrane is positioned between the tray and the lid. A hub assembly is positioned within the tray.
