According to the application, 1,3 propylene glycol from natural sources is used for replacing 1,2 propylene glycol from synthetic sources, so that toxic compounds such as propylene oxide are avoided, and an aerosol-forming substrate containing substances from complete natural sources can be obtained, so that the safety of the aerosol-forming substrate is improved.
Description
Technical Field
The application relates to the technical field of atomization, in particular to an aerosol forming substrate with natural components and an aerosol generating system.
Background
The existing aerosol forming substrate is prepared by blending 1, 2-propylene glycol, glycerol (also called glycerin), nicotine, tobacco special essence and the like. 1, 2-propanediol is typically obtained from the chemical synthesis of propylene, a gas industrially produced by cracking heavier hydrocarbons, and more specifically 1, 2-propanediol is obtained by the hydration reaction of propylene oxide. Propylene oxide is classified by european and north american environmental authorities as a compound that causes mutation and carcinogenesis in animals and possibly carcinogens in humans, and unconverted propylene oxide does not guarantee the absence of carcinogenic contaminants in aerosol-forming substrates. Synthetic 1, 2-propanediol can be removed from existing aerosol-forming substrates for the natural source of the product; however, aerosol-forming substrates that do not contain 1, 2-propanediol are prone to damage to the aerosolization device (e.g., an electronic aerosolization device) and can reduce the user's aspiration experience.
Therefore, there is a need to propose a new solution for the natural sources of aerosol-forming substrates.
Disclosure of Invention
The present application aims to provide an aerosol-forming substrate of natural composition and an aerosol-generating system to avoid the problems of the existing aerosol-forming substrates in which 1,2 propanediol of synthetic origin is present.
In one aspect, the application provides a natural component aerosol-forming substrate comprising 1,3 propanediol of natural origin in place of 1,2 propanediol of synthetic origin.
The inventors found that when an aerosol-forming substrate having a melon flavor prepared using a melon-like substance is added, there is a problem in that the content of melon aldehyde is unexpectedly reduced by using an aerosol-forming substrate of 1,2 propanediol. Surprisingly, however, the combination of guar and 1,3 propanediol allows the guar content to be maintained at a higher desired level. Accordingly, the present application also aims to provide an aerosol-forming substrate comprising 1,3 propanediol and guar of natural origin, so as to avoid the problem of a substantial reduction of the guar content in the aerosol-forming substrate.
Advantageously, the guar content in the aerosol-forming substrate is greatly increased after the same level of 1, 2-propanediol has been replaced with 1, 3-propanediol.
In some embodiments, the mass percent of said melon aldehyde is 0 to 5%, preferably 0.01 to 5%, more preferably 0.02 to 4%, more preferably 0.02 to 3%, more preferably 0.02 to 2%, more preferably 0.03 to 1%, based on the total mass of the aerosol-forming substrate of said natural component.
In some embodiments, the mass percent of 1,3 propanediol is 0.1% to 19.99%, preferably 0.1% to 15%, more preferably 1% to 15%, more preferably 5% to 15% based on the total mass of the aerosol-forming substrate of the natural component.
In some embodiments, the aerosol-forming substrate of the natural component further comprises at least one of glycerin, nicotine substitutes, benzoic acid.
In some embodiments, the glycerol is 0% to 95%, preferably 38% to 95%, more preferably 45% to 95%, even more preferably 79% to 95%, even more preferably 85% to 95% by mass of the total mass of the aerosol-forming substrate of the natural component.
In some embodiments, the nicotine or the nicotine substitute is 0 to 5%, preferably 0.5 to 5%, more preferably 0.5 to 4%, more preferably 0.5 to 3%, more preferably 0.5 to 2% by mass of the total mass of the aerosol-forming substrate of the natural component.
In this embodiment, the nicotine replacement is typically a non-addictive molecule having a sensory effect similar to nicotine.
In some embodiments, the benzoic acid is present in an amount of 0 to 5%, preferably 0.5 to 5%, more preferably 0.5 to 4%, more preferably 0.5 to 3%, more preferably 0.5 to 2% by mass of the total mass of the aerosol-forming substrate of the natural component.
In this embodiment, the irritation of the aerosol-forming substrate of the natural component can be reduced by the benzoic acid, enhancing the user's aspiration experience.
In some embodiments, the glycerin, the nicotine replacement, and the benzoic acid are all obtained from natural sources.
In another aspect the application provides an aerosol-generating system comprising an aerosolization device and an aerosol-forming substrate of the natural component; the atomizing device is configured to atomize the aerosol-forming substrate of the natural component to generate an aerosol.
According to the aerosol-forming substrate and the aerosol-generating system of the natural component, 1,3 propylene glycol from natural sources is used for replacing 1,2 propylene glycol from synthetic sources, so that toxic compounds such as propylene oxide are avoided, and meanwhile, the aerosol-forming substrate containing substances from complete natural sources can be obtained, and the safety of the aerosol-forming substrate is improved.

MS end: the ion source temperature is 230 ℃ and the interface temperature is 280 ℃.
Heating program: keeping at 50 ℃ for 3min, and rising to 150 ℃ at 5 ℃/min; raising the temperature to 300 ℃ at 15 ℃/min, and keeping the temperature for 3min.
The acquisition method comprises the following steps: solvent delay 1.65min; scan mode 1.80min-3.80min:30m/z-200m/z;3.80min-35.00min:47m/z-500m/z.
Test results:
| aldehyde content at ambient temperature | Aldehyde content under heating | |
| Example six | 3907778 | 1087052 |
| Comparative example 3 | 3070374 | 564192 |
| Comparative example 4 | 34661 | 19339 |
| Comparative example 5 | 568146 | 43329 |
| Comparative example 6 | 32843 | 35688 |
| Comparative example 7 | 58201 | 62501 |
Wherein, the aldehyde content is the peak area of the response value in the instrument. The peak area is the total area of the portion above the background line in the chromatogram, and represents the content of the analyte, and the larger the area is, the higher the content is. The aldehyde content at normal temperature refers to the result measured after the aerosol-forming substrate is left to stand at normal temperature for 24 hours. The aldehyde content under heating refers to the result measured when heated in a water bath at 60℃for 24 hours.
The results show that the guar content in example six is 1.27 times (at normal temperature) or 1.93 times (under heating) that in comparative example 3 after the same amount of 1, 2-propanediol was replaced with 1, 3-propanediol. Whereas the benzaldehyde content in comparative example 4 is much smaller than that in comparative example 5, the trans-2-hexenal content in comparative example 6 is much smaller than that in comparative example 7.
The results further show that in case 1, 3-propanediol is used, the content of guar in example six far exceeds the content of benzaldehyde in comparative example 4 and the content of trans-2-hexenal in comparative example 6.
Thus, it is also unexpected by the inventors that the use of a combination of guar and 1,3 propanediol can maintain the guar content at a higher desired level.
