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.

The present invention relates to personal care compositions comprising malodor reduction compositions and methods of making and using such personal care compositions. Such personal care compositions comprising the malodor control technologies disclosed herein provide malodor control without leaving an undesirable scent and when perfume is used to scent such compositions, such scent is not unduly altered by the malodor control technology.

An open-cell foam structure that is impregnated with a disinfectant and used to remove pathogens from air, water, and surfaces, and kill the pathogens

A method for sanitizing an indoor environment includes placing a high-output hydroxyl generator within an indoor environment and commencing a hydroxyl shock treatment of the indoor environment by activating the high-output hydroxyl generator. The method also includes applying a disinfectant to hard surfaces or soft surfaces within the indoor environment and applying a microbial growth prevention agent to flooring or the hard surfaces within the indoor environment. The method also includes deactivating the high-output hydroxyl generator and removing the high-output hydroxyl generator from the indoor environment.

An apparatus includes multiple first reservoirs and multiple second reservoirs joined with a substrate. Selected ones of the multiple first reservoirs include a reducing agent, and first reservoir surfaces of selected ones of the multiple first reservoirs are proximate to a first substrate surface. Selected ones of the multiple second reservoirs include an oxidizing agent, and second reservoir surfaces of selected ones of the multiple second reservoirs are proximate to the first substrate surface.

In various embodiments, an air purifier capable of destroying and deactivating airborne contaminants such as SARS-CoV-2 is described. The air purifier comprises a photocatalytic system comprising at least one photoactivated semiconductor photocatalyst and a lamp configured to irradiate and excite the at least one photoactivated semiconductor photocatalyst to generate reductive and/or oxidative reactive species from oxygen and/or water on the photocatalyst surface. In various embodiments, the photocatalytic system comprises a stack of PCB cards, each card having a photocatalytic layer disposed thereon, or a 3-dimensionally ordered macroporous (3-DOM) structure comprising an open cell lattice.

A material for deactivating a pathogenic aerosol includes a supporting fibrous layer and a salt crystal disposed on the supporting fibrous layer. The salt crystal is a coating layer, which partially or completely covers the supporting fibrous layer. The salt crystal includes one or more of sodium, potassium, chloride, magnesium, sulfate, ammonium, phosphate, glutamate, tartrate, and their ions, and the material has an air filtration efficiency of at least 5%.

An aerial sanitizer for use in indoor spaces may be created by dispersing an operative fluid within a fluid dispersion device or other like apparatus. The operative fluid may be comprised of a first compound, such as triethylene glycol, or any other like compound sufficiently effective as an aerial germicide. Because of the hygroscopicity and low toxicity of triethylene glycol, or other like germicidal compounds, the operative fluid may further include a second compound, such as deionized water, to devise the operative fluid in dynamic equilibrium with the surrounding ambient air, such that the triethylene glycol or other like compound will abstain from ambient water uptake, thereby preventing the dilution of the operative fluid. Such an operative fluid may further include a third compound, such as alternative essential oils, for both germicidal activity and the provision of certain sensory signals, whether organoleptic or otherwise.

The present invention relates to a fragrance composition containing a fragrance component which suppresses response strength of at least one olfactory receptor polypeptide, which is selected from the group consisting of OR2L3 and polypeptides that comprise an amino acid sequence having at least 80% identity to an amino acid sequence of OR2L3 and are responsive to an unpleasant odor-causing substance, to the unpleasant odor-causing substance. According to a preferred embodiment of the present invention, an unpleasant odor masking composition containing, as active components, at least one antagonist against an olfactory receptor OR2L3 and a specific component among fragrances which do not exert the effect of suppressing the response of OR2L3, is provided. According to a preferred embodiment of the present invention, unpleasantness caused by at least one unpleasant odor selected from the group consisting of fecal odor, body odor, tobacco odor, breath odor and musty odor can be reduced.

A mask assembly having antimicrobial properties is provided. The mask is preferably worn on a user's face and it comprises a material layer, preferably a polyester fabric, and an applied emulsion or combination of chemical components (a silver containing stabilized solution and a phosphorescent compound). The combination provides enhanced antimicrobial properties in the mask via the silver containing stabilized solution and the phosphorescent compound, which emits a controlled field around the mask of microbe destroying UV-C radiation, preferably in the 200-290 nm wavelength range. The emulsion may be applied to other surfaces wherever antimicrobial properties are desired.
