A fragrance composition which reduces malodor during chemical treatment of keratin fibers is described. The keratin fibers may be human keratin fibers, such as human hair. The fragrance compound comprises p-mentha-8-thiol-3-one, cis-3-hexenol, cis-3-hexenyl acetate, and allyl amyl glycolate and further comprises one or more organic solvents selected from the group consisting of benzyl alcohol, dipropylene glycol, isopropyl myristate, and ethanol in an amount of 1% by weight or more, calculated to the total weight of the composition.

An essential oil diffusion mechanism, including: a housing having an accommodation chamber; and a separator that divides the accommodation chamber into an upper chamber and a lower chamber and includes a horizontal partition plate and vertical partition plates. The horizontal partition plate defines at least one interconnecting hole. An upper surface of each vertical partition plate is spaced apart from a chamber wall of the upper chamber to form an upper interconnecting aperture. Each vertical partition plate defines an interconnecting reflux hole. A lower surface of each baffling plate is spaced apart from the horizontal partition plate to form a lower interconnecting aperture. The interconnecting hole, the upper interconnecting aperture, the lower interconnecting aperture, and the air outlet are sequentially arranged in communication to form an air outlet channel. The upper interconnecting aperture, the reflux hole, and the interconnecting hole are sequentially arranged in communication to form a reflux channel.

The invention relates to automated devices for pro¬ducing aerosols of liquid disinfectants and for spraying same. A mo¬bile hygiene unit comprises a housing (1) containing a disinfectant spraying unit (2) with a spraying nozzle (3), a tank (4) containing disinfectant, a compressor (5), and a control unit (6). It further com¬prises a mechanism for regulating the droplet size distribution of the aerosol, including a pump (7), an electromagnetic valve (8), and a dosing nozzle (9) with an internal cylinder. The disinfectant spraying unit (2) comprises a shaped nozzle (3) having a nozzle head (10) of axisymmetric cross-section attached thereto, and a mixing chamber (11) for mixing disinfectant with compressed air, having two thread¬ed inlets for a pneumatic line (12) and a hydraulic line (13), said inlets being arranged at an angle of 180°. The dosing nozzle (9) contains an internal cylinder and a rod with a threaded tip. The mobile hygiene unit generates an aerosol in four droplet size distribution modes: dry fog (from 3.5 to 10 pm), wet fog (from 10 to 30 pm), mist (from 30 to 50 pm), and spray (from 50 to 100 pm). The invention allows highly precise regulation of the droplet size distribution of the aerosol in each mode without the need to change the spraying nozzle.

The present invention relates to a hydrogen peroxide vapor generation device, a space sterilization apparatus including same, and a space sterilization method, including: an evaporation chamber which has a space formed therein, and includes a nozzle unit and a discharge port which are formed in an upper portion thereof; an evaporation unit which is formed in a lower inner portion of the evaporation chamber and equipped with a plurality of heating units and a hydrogen peroxide transfer pipe which are arranged in stack; and an air supply unit which is formed in a lower portion of the evaporation chamber and through which outside air is suctioned, discharged, and fed to the evaporation unit.

This disclosure relates to a method for sanitizing a space. The method includes applying a composition containing triethylene glycol into a space containing a pathogen (e.g., a Staphylococcus, a Pseudomonas, a Listeria, Salmonella, Klebsiella, a Mycobacterium, a mold, or a spore) in an amount effective to inactivate the pathogen.

Various embodiments of the present invention relate to, among other things, a nano carrier platform for generating enhanced engineered water nanostructures (iEWNS) encapsulating and delivering reactive oxygen species (ROS) and, in some instances, other active ingredients, methods for inactivating at least one of viruses, bacteria, bacterial spores, and fungi on a substrate by applying iEWNS to the substrate.

The process includes a treatment step during which a liquid containing a biocidal and/or plant-protection product or a mixture of biocidal and/or plant-protection products is evaporated and injected into the internal atmosphere of premises, the liquid being evaporates at a temperature of less than 50° C., the product vapour concentration in the internal atmosphere of the premises being kept at greater than 10% of a saturation concentration of the vapour of said product in said atmosphere at said temperature for a saturation duration of greater than 12 hours.

A liquid freshening composition is provided. The liquid freshening product includes about 0.5 wt. % to about 15 wt. % isopropyl myristate, by weight of the liquid freshening composition and greater than 40 wt. % of one or more perfume raw materials. The liquid freshening composition has a vapor pressure at 25° C. of about 0.03 Torr to about 1.0 Torr. The liquid freshening composition may be used with air freshening products having a delivery engine such as a wick, breathable membrane, gel, porous and semi-porous substrate, and combinations thereof.
