A freshening composition and a consumer product that includes the freshening composition are provided. The freshening composition includes cyclodextrin; a silicone anti-foam agent, and a liquid carrier. The freshening composition includes a weight ratio of silicone anti-foam agent to cyclodextrin of less than 0.00375:1. A consumer product may include the freshening composition disposed in a spray dispenser.

Articles can be provided with odor resistance by applying a dispersion of a halogenated heterocyclic N-halamine in an inert liquid carrier onto the surface of the article and allowing the inert liquid carrier to penetrate into it. The N-halamine accordingly becomes deposited on the surface of the article after the inert liquid carrier penetrates into the article. This method can be used to provide odor resistance to a variety of substrates, including garbage bags. It can also be used to deposit other functional particulates onto the surface of substrates having sufficient porosity to take up the vehicle. For instance, such functional particles can be oxidants that display antimicrobial and/or enzyme inhibitory efficacy or particles having toxin interaction potentials through oxidative degradation or adsorption of toxic substances in air and/or water, such as fluoride uptake by metal oxide microparticles.

An apparatus for air freshening in an interior occupancy space. The apparatus has a reservoir containing a volatile composition for air freshening and/or malodor removal and a composite membrane in fluid communication with the volatile composition. The composite membrane has a first side facing the reservoir and a second side opposite the first side. At least one of the first side and the second side has a diffusion regulating coating, the diffusion regulating coating including a hydrophobic/oleophobic material having at least one fluoro-alkyl group. The volatile composition includes at least 20% of perfume raw materials by weight of the composition, the at least 20% of perfume raw materials having an average vapor pressure equal to or greater than 0.01 torr at 25 degrees Celsius. The apparatus has an average vapor release rate from 0.2 mg/hr*cm.sup.2 to 5 mg/hr*cm.sup.2 at an air flow rate of 5 m/s and a temperature of 21 degrees Celsius.

An air treatment device having a flexible air hose, duct or gooseneck member. The air hose, duct or gooseneck member permits an inlet end thereof to be positioned in proximity to a patient so that a negative pressure can be created around the patient so that air can sucked or vacuumed into the system whereupon it is treated as the air flows through the system.

The air freshener composition comprises component A and component B, wherein a weight ratio of the component A to the component B is 1:0.5-3; the component A comprises, in parts by weight, 10-30 parts by weight of an active agent; 6-15 parts by weight of a carrier; 1-4 parts by weight of a pH regulator; and 0.01-0.2 part by weight of an antioxidant; the component B is a plant extract solution, wherein the plant extract solution comprises at least, in parts by weight: 5-30 parts by weight of an extract of a mixture of Populus nigra var. italica, grapefruit peels and eucalyptus leaves; 0.1-5 parts by weight of Sophora flavescens extract; 1-3 parts by weight of Aloe vera extract; 1-10 parts by weight of fresh orange peel extract; 0.5-3 parts by weight of Nandina domestica extract; 0.5-10 parts by weight of Eucalyptus robusta Smith extract; 1-8 parts by weight of Robinia pseudoacacia L. extract; 1-5 parts by weight of Chrysanthemum morifolium extract; and 0.1-2 parts by weight of artemisinin.

An air purification composition. The air purification composition includes patchouli, lavender, lemon, lemongrass, rosewood, white camphor and tea tree. The air purification composition has the form of a fluid concentrate which can be used by itself or in combination with other ingredients. The air purification composition may be utilized in a targeted area to improve the air quality and scent of the air.

A disinfecting unit and method of operating the same includes a cabinet having a vertical axis, a first lamp coupled to the cabinet directing light in a generally radial direction relative to the vertical axis, a second lamp coupled to the cabinet directing light in at least a partially axial direction relative to the vertical axis and a nebulizer that dispenses disinfecting fluid therethrough.

Chlorine dioxide gas is immediately generated at a stable concentration from a liquid composition. The composition is obtained by mixing an aqueous chlorite solution, an activator that immediately adjusts the pH of the aqueous chlorite solution, an activation inhibitor that slowly mitigates an action of the activator, and a metal iodide such that the metal iodide is contained in a proportion of 0.4% by mass or less and the activation inhibitor is contained in a proportion of 1% by mass or less with respect to 1 L of 1% by mass aqueous chlorite solution.

An air purification system including a filter assembly including a substrate including a fibrous media, and a photocatalytic material disposed on the substrate, wherein the photocatalytic material includes a first quantity of crushed nanostructures; and a photon source arranged to illuminate the photocatalytic material with optical radiation.

Chlorine dioxide gas is generated at a stable concentration from a liquid composition. The composition is obtained by mixing an aqueous chlorite solution, an activator that immediately adjusts a pH of the aqueous chlorite solution, thereby causing the aqueous chlorite solution to generate chlorine dioxide gas, and an activation inhibitor that slowly mitigates an action of the activator.
