• a fragrance is a chemical substance that stimulates the sense of smell.
• the chemical substance should be at least partially dispersible in the air, ie the fragrance should be at least slightly volatile at 25°C. If the fragrance is now very volatile, the odor intensity will quickly subside. However, with a lower volatility, the odor impression is more lasting, meaning it does not disappear as quickly.
• the fragrance therefore has a melting point which is in the range from -100°C to 100°C, preferably from -80°C to 80°C, even more preferably from -20°C to 50°C, in particular from - 30°C to 20°C.

• the fragrance has a molecular weight of 40 to 700 g/mol, more preferably 60 to 400 g/mol.
• fragrance The smell of a fragrance is perceived as pleasant by most people and often corresponds to the smell of, for example, flowers, fruits, spices, bark, resin, leaves, grasses, mosses and roots. Fragrances can also be used to mask unpleasant odors or to give a non-smelling substance a desired smell.
• Individual fragrance compounds for example synthetic products of the ester, ether, aldehyde, ketone, alcohol and hydrocarbon type, can be used as fragrances.
• fragrances are preferably used, which together produce an appealing scent.
• a mixture of fragrances can also be referred to as perfume or perfume oil.
• perfume oils can also contain natural fragrance mixtures such as those available from plant sources.
• the fragrance is used in encapsulated form (fragrance capsules), in particular in microcapsules.
• the entire fragrance can also be used in encapsulated form.
• the microcapsules can be water-soluble and/or water-insoluble microcapsules.
• melamine-urea-formaldehyde microcapsules, melamine-formaldehyde microcapsules, urea-formaldehyde microcapsules or starch microcapsules can be used.
• Perfume precursors refer to compounds that release the actual fragrance only after chemical conversion/cleavage, typically through exposure to light or other environmental conditions such as pH, temperature, etc. Such compounds are often referred to as scent storage substances or “pro-fragrance”.
