Disclosed is a fragrance apparatus, belonging to the technical field of aromatherapy devices. The fragrance apparatus includes a fragrance component and a main component; the fragrance component includes a liquid storage bin, a liquid guide, a heater, and a first connector; the first connector is detachably connected to the main component; the liquid storage bin is provided with a closed liquid storage chamber for storing an essential oil, the liquid guide is in fluid communication with the liquid storage chamber, the liquid guide is used for transporting the essential oil in the liquid storage chamber, and the heater can heat the essential oil in the liquid guide to volatilize and diffuse the essential oil outward. In the fragrance apparatus, the first connector can be detachably connected to the main component, so that the fragrance component forms a replaceable and relatively independent module for sealing the essential oil therein; further, the essential oil is stored in the closed liquid storage chamber and is not in direct contact with air, and the essential oil is heated by the heater to volatilize and diffuse, so that the fragrance component can prevent waste caused by the volatilization of the essential oil and can also prevent the essential oil from being oxidized and deteriorated.

Composition comprising 7-43 wt.% dipropylene glycol (DPG), 28-50% ethanol, 30-45% water and 0.01-1% sheer fragrance, where the sheer fragrance comprises more top notes than bottom notes. An aerosol product comprising 70-80% of the composition and 20-30% propellant capable of producing 414 kPa pressure and an air treatment method comprising generating the aerosolised spray from the aerosol product to produce 5-30 ppm DPG vapour to disinfect air and reduce malodour are also included. The composition may comprise 0.1-5% cationic surfactant and a pH adjuster to adjust the pH to 9-11. The composition may include 10-25% DPG. The fragrance may comprise less than 50% volatile solvent, 10-80% top notes and include a profragrance. The composition may be free from antimicrobials and surfactants other than the cationic surfactant. The composition may be detectable for up to 1 hour and produce at least a 90% reduction in perception of malodour after 10 minutes. The average spray particle size may be Dv[50]=45 to Dv[50]=90 microns. The hang time may be at least 20 minutes and the composition may provide at least a 3 log10 bacterial reduction. The spray may be generated using a 2-piece mechanical breakup (MB) nozzle with swirl chamber or break up bar.
