Description

Technical Field

[0001] The invention relates to the field of atomization, and in particular to a composite cooling agent, atomizing liquid and an atomizing device. Background Art

[0002] The mechanism of action of the atomizer is to convert the atomized liquid into an aerosol through the atomizer for human inhalation. Users have a demand for a cool feeling from atomizers with flavors such as fruit and mint. The components that provide a cool feeling in the atomizer liquid are mainly composed of food-grade coolants. The commonly used coolant in the atomizer liquid is WS-23 (N,2,3-trimethyl-2-isopropylbutanamide), which has an excellent cooling effect in the nasal cavity and throat. However, the use of WS-23 in atomizer liquid is prohibited in Italy and some regions. Therefore, it is necessary to study a composite coolant that does not contain WS-23 but has a cooling intensity equivalent to that of WS-23 and is suitable for atomization, so as to meet consumers' demand for a cool feeling when using atomizer devices. Summary of the invention

[0003] Based on this, some embodiments of the present invention provide a composite cooling agent that does not contain WS-23 and has a cooling sensation equivalent to that of WS-23, is suitable for inhalation by an atomizing device, and improves the richness and comfort of the cooling sensation.

[0013] In some of these embodiments, the atomization liquid further includes one or several of essence, sweetener, and nicotine salt.

[0014] In some of these embodiments, based on the mass percentage of the atomization liquid being 100%, the mass percentage of the essence is 0 - 30%, the mass percentage of the sweetener is 0 - 8%, and the mass percentage of the nicotine salt is 0 - 10%.

[0015] An atomization device includes the above-mentioned atomization liquid.

[0016] The above compound cooling agent is prepared by compounding WS-3 (N-ethyl-p-menthane-3-carboxamide), WS-5 (N-(ethoxycarbonylmethyl)-p-alkane-3-carboxamide), and WS-27 (N,2-diethyl-2-isopropyl-3-methylbutyramide) in a certain proportion, so that the compound cooling agent can have a cooling sensation equivalent to that of WS-23 and be suitable for atomization without containing WS-23, improving the richness and comfort of the cooling sensation part, and further enhancing the e-cigarette cooling experience of users in areas where WS-23 is prohibited.

[0029] The first aspect of the present application provides a compound cooling flavorant, which, by mass parts, includes: 10 parts to 35 parts of WS-3 (N-ethyl-p-menthane-3-carboxamide), 0 to 40 parts of WS-5 (N-(ethoxycarbonylmethyl)-p-alkane-3-carboxamide), and 30 parts to 90 parts of WS-27 (N,2-diethyl-2-isopropyl-3-methylbutyramide), and the compound cooling flavorant does not contain WS-23.

Optionally, in the compound cooling flavorant, the mass parts of WS-3 are 14 parts to 31 parts.

[0031] In an alternative example, in the compound cooling flavorant, the mass parts of WS-5 can be but are not limited to 0 parts, 5 parts, 10 parts, 15 parts, 18 parts, 20 parts, 22 parts, 25 parts, 28 parts, 30 parts, 32 parts, 35 parts, 38 parts, 40 parts, or the range formed by any two of these values. Optionally, in the cooling flavorant, the mass parts of WS-5 can be but are not limited to 0 parts to 33 parts.

[0032] In an alternative example, in the compound cooling flavorant, the mass parts of WS-27 can be but are not limited to 30 parts, 35 parts, 40 parts, 45 parts, 50 parts, 55 parts, 60 parts, 65 parts, 70 parts, 75 parts, 80 parts, 85 parts, 90 parts, or the range formed by any two of these values. Optionally, in the compound cooling flavorant, the mass parts of WS-27 are 36 parts to 86 parts.

[0033] In some embodiments, the total mass parts of the compound cooling flavorant is 100 parts.

[0034] In some embodiments, the compound cooling flavorant does not contain menthol.

[0035] In some embodiments, by mass parts, the compound cooling flavorant consists of 10 parts to 35 parts of WS-3, 0 to 40 parts of WS-5, and 30 parts to 90 parts of WS-27.

[0036] In some embodiments, by mass parts, the compound cooling flavorant includes: 14 parts to 31 parts of WS-3, 0 to 33 parts of WS-5, and 36 parts to 86 parts of WS-27. Further, by mass parts, the compound cooling flavorant consists of 14 parts to 31 parts of WS-3, 0 to 33 parts of WS-5, and 36 parts to 86 parts of WS-27.

[0037] In some embodiments, in the compound cooling flavorant, the mass ratio of WS-5 to WS-3 is (0 to 3):1. For example, the mass ratio of WS-5 to WS-3 can be but is not limited to 0:1, 0.1:1, 0.2:1, 0.5:1, 0.6:1, 0.8:1, 1:1, 1.2:1, 1.5:1, 1.8:1, 2:1, 2.2:1, 2.5:1, 2.8:1, 3:1, or the range formed by any two of these values. Optionally, the mass ratio of WS-5 to WS-3 is (0 to 1.2):1.

[0038] In some embodiments, the mass ratio of WS-5 to WS-27 is (0 to 1.2):1. For example, the mass ratio of WS-5 to WS-27 can be but is not limited to 0:1, 0.1:1, 0.2:1, 0.3:1, 0.4:1, 0.5:1, 0.6:1, 0.7:1, 0.8:1, 0.9:1, 1:1, 1.2:1, or the range formed by any two of these values.

[0039] The inventors found that because the atomization temperature range of the atomization device is between 200°C and 300°C, the cooling flavorants with boiling points within this range provide a better cooling effect after atomization than those outside this range. The types of common cooling flavorants in the atomized liquid and their boiling points are shown in Table 1 below:

[0040] Table 1 Types and boiling points of common cooling flavorants

[0041]

[0042] The inventors' research found that although the cooling intensity of WS-27 can reach a level close to that of WS 23 after atomization in e-cigarettes, its off-flavor is significant. The main cooling sensation of WS-3 and WS-5 after atomization is in the lower throat, and the cooling sensations in the nasal cavity and oral cavity are not significant, and WS-5 also has an off-flavor. By compounding the above components in a certain proportion, the compound cooling flavorant can have a cooling effect equivalent to that of WS-23 and be suitable for atomization without containing WS-23, improving the richness and comfort of the cooling sensation parts, and further enhancing the e-cigarette cooling experience of users in regions where WS-23 is prohibited.

[0043] Among them, the richness of the cooling sensation means that the more the number of cooling sensation parts, the richer it is, that is, the "rich" cooling sensation can be perceived not only in one or a certain part, but in multiple parts. The comfort of the cooling sensation means that the intensity is moderate and coordinated, that is, the intensity is balanced in different parts and there is no phenomenon of excessive cooling in individual parts; there is no off-flavor or other flavors.

[0044] The second aspect of the present invention provides an atomized liquid, comprising a solvent and the above compound cooling flavorant.

[0045] In some embodiments, in the atomization liquid, the mass percentage of the cooling agent is 0.1% - 10%.

[0046] In some embodiments, the solvent includes one or more of ethanol, propylene glycol, and glycerol. In some of these embodiments, the solvent includes ethanol, propylene glycol, and glycerol.

[0048] In an alternative example, in the atomization liquid, the mass percentage of ethanol can be, but is not limited to, 1%, 2%, 2.5%, 3%, 3.5%, 4%, 4.5%, 5%, 5.5%, 6%, 7%, 8%, 9%, 10% or the range composed of any two of these values. Specifically, the volume percentage concentration of ethanol is 95%.

[0049] In an alternative example, in the atomization liquid, the mass percentage of propylene glycol can be, but is not limited to, 30%, 35%, 36%, 38%, 40%, 42%, 44%, 45%, 46%, 48%, 50%, 55%, 60%, 65%, 70% or the range composed of any two of these values.

[0050] In an alternative example, in the atomization liquid, the mass percentage of glycerol can be, but is not limited to, 20%, 22%, 25%, 28%, 30%, 32%, 35%, 38%, 40%, 42%, 45%, 48%, 50% or the range composed of any two of these values.

[0051] In some embodiments, the atomization liquid further includes one or more of essence, sweetener, and nicotine salt.

[0052] Specifically, based on the mass percentage of the atomization liquid being 100%, the mass percentage of the essence is 0 - 30%, the mass percentage of the sweetener is 0 - 8%, and the mass percentage of the nicotine salt is 0 - 10%.

[0053] For example, in the atomization liquid, the mass percentage of the flavoring agent can be, but is not limited to, 0, 1%, 5%, 10%, 15%, 20%, 25%, 30%, or the range composed of any two of these values. In the atomization liquid, the mass percentage of the sweetening agent can be, but is not limited to, 0, 1%, 2%, 3%, 4%, 5%, 6%, 7%, 8%, or the range composed of any two of these values. In the atomization liquid, the mass percentage of the nicotine salt can be, but is not limited to, 0, 1%, 2%, 3%, 4%, 5%, 6%, 7%, 8%, 9%, 10%, or the range composed of any two of these values.

[0054] In an optional example, the flavoring agent includes, but is not limited to, one or several of strawberry flavor, watermelon flavor, lemon flavor, peach flavor, mango flavor, papaya flavor, orange flavor, grape flavor, litchi flavor, pitaya flavor, pomelo flavor, apple flavor, banana flavor, and coconut flavor.

[0056] In an optional example, the nicotine salt can be a salt formed by nicotine and an organic acid, and the organic acid can be, but is not limited to, benzoic acid, tartaric acid, etc.

[0057] In some of these embodiments, based on the mass percentage of the atomization liquid being 100%, the atomization liquid includes 0.1% - 10% of a compound cooling flavor, 1% - 10% of ethanol, 30% - 70% of propylene glycol, 20% - 50% of glycerin, 0 - 30% of a flavoring agent, 0 - 8% of a sweetening agent, and 0 - 10% of a nicotine salt.

[0058] In some embodiments, the preparation steps of the atomization liquid include: uniformly stirring the compound cooling flavor and the solvent to obtain the atomization liquid. There are no specific limitations on the specific stirring steps, as long as the components can be mixed evenly.

[0059] The third aspect of the present invention provides an atomization device, including the above-mentioned atomization liquid.

[0060] Specifically, the above-mentioned atomization liquid is filled into the atomization device for inhalation. Among them, the atomization device includes an atomization core. For example, the atomization core can be, but is not limited to, a ceramic heating core.

Evaluated by 30 professional sensory evaluators, the coolness of the atomization liquids of each example and comparative example is scored for the oral cavity, larynx, lower larynx, nasal cavity, and off-flavors. Taking the coolness score of the atomization liquid prepared from 5 parts of WS-23, 40 parts of glycerol, and 55 parts of propylene glycol in each sensory indicator as standard 1, and then standardizing the scores obtained for each example and comparative example as the scores of each sensory indicator. The specific results are shown in Table 5. In Table 5, the coolness richness is the standard average of the coolness degrees in the oral cavity, larynx, lower larynx, and nasal cavity.

[0128]

[0129] It can be seen from the comparison between the above-mentioned examples and comparative examples that the standard scores of the cool feeling richness of the atomized liquids prepared in the above-mentioned examples are all ≥1.2, and the cool feeling richness is good.

[0130] It can be seen from the comparison between Comparative Example 1 and Example 1 above that when the mass fraction of WS-3 in the compound cool flavoring agent is less than 10 parts, the cool feeling in the lower throat will be significantly reduced, thus affecting the overall cool feeling richness.

[0131] It can be seen from the comparison between Comparative Example 2 and Example 3 above that when the mass fraction of WS-3 in the compound cool flavoring agent is higher than 35 parts, the cool feeling in the throat is significant, while the cool feelings in the nasal cavity and oral cavity are not significant. Therefore, the synergistic effect of the cool feelings in the oral cavity, nasal cavity and throat is not obvious.

[0132] It can be seen from the comparison between Comparative Example 3 and Example 6 above that in the compound cool flavoring agent, when the mass fraction of WS-5 is higher than 40 parts, the cool feeling in the lower throat is significantly reduced, the cool feelings in the nasal cavity and oral cavity are not significant, and the synergistic effect of the cool feelings in the oral cavity, nasal cavity and throat is not obvious.

[0133] It can be seen from the comparison between Comparative Example 4 and Example 8 above that in the compound cool flavoring agent, when the mass fraction of WS-27 is less than 30 parts, the contribution to the cool feelings in the oral cavity, nasal cavity and throat is low, reducing the overall sensory cool feeling richness.

[0134] It can be seen from the comparison between Comparative Example 5 and Example 9 above that in the compound cool flavoring agent, when the mass fraction of WS-27 is greater than 90 parts, its peculiar smell is significant and the sensory experience is poor.

[0135] The technical features of the above-mentioned examples can be combined arbitrarily. For the sake of concise description, not all possible combinations of the technical features in the above-mentioned examples are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.
