The present invention provides a porous sustained-release body in which transparency of a porous carrier changes. The porous sustained-release body includes an inorganic monolithic porous body 1 including a skeleton body 2 of an inorganic compound and air gaps 3,4 having a three-dimensional continuous network structure formed in the skeleton body 2, and a sustained-release liquid absorbed into air gaps 2, 3, wherein the inorganic monolithic porous body 1 is opaque at an initial state, which is a state before absorption of the sustained-release liquid in which air exists in the air gaps, and refractive index of the sustained-release liquid and refractive index of the skeleton body are the same within an error range within which a portion in which the sustained-release liquid is absorbed into the air gaps changes to transparent or semitransparent.

Described herein is a method of using volatile compositions to limit, decrease or eliminate a perception of fecal malodour. Such compositions include a malodour antagonist system associated with perfuming ingredients performing as malodour counteractant, in a combination that significantly reduces the perception of fecal malodour. Such compositions, methods of using the compositions in combination with delivery systems and their applications in consumer products are described herein.

A dissolvable effervescent toilet deodorizer includes a combination of citric acid, sodium bicarbonate, and essential oils. In one method of use, a user would drop the dissolvable effervescent toilet deodorizer into the toilet bowl just prior to using the toilet. Once dropped into the toilet bowl, the dissolvable effervescent deodorizer begins to dissolve and effervesce. As a result of the effervescence, the dissolution occurs more rapidly and also disperses the deodorizer/scent into the toilet water and air to more effectively neutralize and/or prevent malodors.

The present specification relates to a plasma and VHP combined sterilizer comprising a housing. More particularly, the plasma and VHP combined sterilizer comprises: a discharge unit, which is provided at the upper end of a housing and discharges predetermined amount of vaporized hydrogen peroxide; a suction fan, which is provided at one side of the housing and suctions the outer air and discharged hydrogen peroxide; a plasma generation unit including a plurality of plasma modules for generating the outer air and hydrogen peroxide, which are suctioned through the suction fan, as plasma ions through plasma discharge; and a control unit for controlling the overall operation of the plasma and VHP combined sterilizer.

Fragrant compositions including a blend of essential oils suitable for use in fragrance-emitting articles are provided herein. Articles formed by infusing such compositions into porous substrates, such as rock, are also provided according to aspects of the present technology, and these may be particularly useful as an animal repellant in both indoor and outdoor spaces.

Disclosed are methods and apparatus that help reduce and prevent infection by controlling and/or reducing the level of contaminants, which include pathogens, allergens and/or odor-causing agents including VOCs. Photocatalytic oxidation is performed in a high humidity environment so that hydrogen peroxide molecules are readily produced.

Controlled-release core/shell composite materials and methods of use are described. A composite material can include a hierarchical structured zeolite core having at least a bimodal pore structure with a first active agent loaded into pores of the core, and (b) a porous polymeric outer shell that substantially encompasses the zeolite core. The composite materials can be configured to controllably release the first active agent from the zeolite core and the porous polymeric shell in response to at least one stimulus.

An odour neutralising structure comprising a wall rail section arranged to hang a stretched fabric in order to produce a false wall and at least one filter cartridge containing a sorbent material that can absorb one or more specific odour(s), said cartridge being housed in a groove in the wall rail section.

A sterilant source for use in a portable sterilant system includes a gas-impermeable vial, a frangible ampule containing a first sterilant gas precursor material, disposed within the gas-impermeable vial, a second sterilant gas precursor material, disposed within the gas-impermeable vial and outside the ampule. The first and second sterilant gas precursor materials are selected to be mutually reactive to generate a sterilant gas. The system further includes an activation mechanism, actuatable to break the frangible ampule to release the first sterilant gas precursor material to allow it to react with the second sterilant gas precursor material to generate the sterilant gas.

An electro-ionic device configured for being worn on the face of a person is disclosed. The electro-ionic device includes at least two electrical conductors spaced apart from each other defining at least a portion of a respiratory pathway therebetween and a circuit configured to apply a first voltage between the two conductors during inspiration and a second voltage greater than the first voltage during expiration.
