Description

Technical Field

[0001] This application relates to the field of fragrance technology, and in particular to a vapor-sensitive fragrance, its preparation method, and its application. Background Technology

[0002] Electronic atomizing devices are gradually being accepted by the market due to their characteristics such as no open flame and low tar content. When using electronic atomizing devices, in addition to requirements for the intensity and complexity of the aroma, "vapor sensation," which is the combined experience of the impact, coolness, and expansion felt in the throat, is also one of the core indicators affecting the user experience.

[0003] Existing flavorings used in electronic atomizing devices primarily focus on aroma blending, with relatively limited methods for enhancing the vapor sensation. Common approaches include adding single ingredients such as menthol or cooling agents. However, this method has significant drawbacks: firstly, the vapor sensation from a single cooling agent is short-lived, easily resulting in a "cooling at first, then fading" effect, failing to match the aroma release rhythm; secondly, some cooling agents have poor compatibility with base oils in the atomizing matrix (such as propylene glycol and glycerin), leading to layering and crystallization during long-term storage, affecting product stability; furthermore, some traditional vapor-sensing additives are excessively irritating or have questionable safety, failing to meet the food-grade raw material requirements of relevant industry standards for electronic atomizing devices.

[0004] Therefore, developing a vapor-featured fragrance for electronic atomizing devices that has a long-lasting vapor sensation, good compatibility with atomizing matrix, high safety, and can synergistically enhance the user experience with aroma has become an urgent need in the industry. Summary of the Invention

[0005] The purpose of this application is to provide a vapor-sensitive flavoring, its preparation method, and its application.

[0006] To achieve the above objectives, this application adopts the following technical solution:

[0007] This application discloses a vapor-sensory fragrance, comprising a vapor-sensory enhancer and a solvent, wherein the vapor-sensory enhancer comprises at least one of propylene carbonate, dimethyl carbonate, and γ-butyrolactone.

[0008] It should be noted that the vapor-enhancing flavor of this application creatively uses at least one of propylene carbonate, dimethyl carbonate, and γ-butyrolactone as a vapor-enhancing agent, giving it good volatility. During the heating process of the electronic atomization device, it can quickly vaporize, producing a noticeable expanding and impactful sensation. At the same time, it has excellent compatibility with the base oil and does not exhibit stratification. The vapor-enhancing flavor of this application achieves a long-lasting vapor sensation, perfect integration with the atomization matrix, and food-grade safety. It also has the effect of synergistically enhancing the smoking experience with aroma and vapor sensation. This solves the problems of existing vapor-enhancing additives, such as short-lived vapor sensation, poor compatibility with the atomization matrix, insufficient safety, and inability to synergize with aroma.

[0009] This application also discloses a method for preparing the vapor-sensory fragrance of this application, including the following steps:

[0010] (1) Weigh the solvent and heat it at 30-40℃ while stirring at 100-200r / min for 5-10 minutes.

[0011] (2) Add the vapor enhancement agent while stirring, and continue stirring for 20-30 minutes.

[0012] It should be noted that the preparation method of this application is simple in process, easy to operate, and does not require special and expensive equipment, which can well meet the needs of large-scale industrial production.

[0013] This application also discloses the use of the vapor-sensory flavoring, propylene carbonate, dimethyl carbonate, or γ-butyrolactone in atomizing matrix or electronic atomizing device.

[0014] It should be noted that the vapor-enhancing flavor of this application was specifically developed for use in atomizing matrices and electronic atomizing devices, and therefore can be applied to existing atomizing matrices or electronic atomizing devices. It is understood that the key to the vapor-enhancing flavor of this application lies in the creative addition of at least one of propylene carbonate, dimethyl carbonate, and γ-butyrolactone as a vapor-enhancing agent; therefore, propylene carbonate, dimethyl carbonate, or γ-butyrolactone can also be applied to existing atomizing matrices or electronic atomizing devices.

[0015] It should also be noted that, in this application, the application of propylene carbonate, dimethyl carbonate, or γ-butyrolactone in the atomizing matrix or electronic atomizing device mainly refers to the fact that propylene carbonate, dimethyl carbonate, or γ-butyrolactone, as vaporization enhancers of the atomizing matrix, can vaporize rapidly, produce a significant expanding impact sensation, achieve a long-lasting vaporization sensation, can perfectly blend with the atomizing matrix, meet food-grade safety standards, and have the effect of synergistically enhancing the smoking experience with aroma and vaporization sensation.

[0016] This application also discloses an atomizing matrix containing the vapor-sensory fragrance of this application, propylene carbonate, dimethyl carbonate, or γ-butyrolactone.

[0017] It should be noted that the atomizing matrix of this application, due to the use of the vapor-sensing flavor of this application or the addition of propylene carbonate, dimethyl carbonate or γ-butyrolactone, has a significant expanding impact, and the vapor sensation is long-lasting. The vapor-sensing flavor is perfectly integrated with the atomizing matrix, without any layering phenomenon, and can work synergistically with the aroma to enhance the smoking experience, thereby providing users with a better user experience.

[0018] This application also discloses an electronic atomizing device containing the vapor-sensing flavor of this application, the atomizing matrix of this application, propylene carbonate, dimethyl carbonate or γ-butyrolactone.

[0019] It should be noted that the electronic atomizing device of this application, due to the use of the vapor-featured flavoring of this application or the atomizing matrix of this application, or the addition of propylene carbonate, dimethyl carbonate or γ-butyrolactone, also has the effects of obvious expansion and impact, long-lasting vapor sensation, non-layering of the atomizing matrix, and synergistic enhancement of the smoking experience by aroma and vapor sensation.

[0020] Due to the adoption of the above technical solutions, the beneficial effects of this application are as follows:

[0021] The vapor-enhancing flavor of this application creatively employs a vapor-enhancing agent, which can produce a noticeable expanding and impactful sensation, with a long-lasting vapor sensation. It has good compatibility with the base oil phase of the atomizing matrix, with no layering phenomenon, and its safety meets food-grade standards. Furthermore, it can achieve the effect of synergistic enhancement of aroma and vapor sensation to improve the smoking experience, thereby enhancing the user's experience. Detailed Implementation

[0022] To address the shortcomings of existing technologies, this application develops a new vapor-sensing flavoring that solves the problems of short-lived vapor sensation, poor compatibility with the atomizing matrix, insufficient safety, and inability to synergize with aroma in existing vapor-sensing additives. It achieves a long-lasting vapor sensation, perfect integration with the atomizing matrix, food-grade safety, and aroma that synergistically enhances the smoking experience.

[0023] The vapor-sensory fragrance of this application includes a vapor-sensory enhancer and a solvent, wherein the vapor-sensory enhancer includes at least one of propylene carbonate, dimethyl carbonate, and γ-butyrolactone.

[0024] It should be noted that the vapor-featured flavoring of this application has good volatility and can be rapidly vaporized during the heating process of the electronic atomization device, producing a noticeable expanding and impactful sensation. The vapor sensation is also long-lasting and has excellent compatibility with the base oil, without any stratification.

[0025] In some implementations, the vapor-sensitive fragrance of this application also includes a composite cooling agent, which comprises at least two cooling agents with different cooling layer release and / or persistence.

[0026] It should be noted that the main purpose of using two cooling agents is to achieve a layered release of the cooling sensation. Therefore, generally speaking, any cooling agent that can achieve layered release or has different durations of cooling sensation, thus creating a layered cooling effect, can be applied to this application. This application uses a combination of two cooling agents to avoid the irritation and volatility problems of a single cooling agent. The composite cooling agent, through the synergistic effect of different cooling components, can achieve a layered release of the cooling sensation, enhancing the layered sensation and duration of the vaporization.

[0027] It should also be noted that the composite cooling agent of this application can also work synergistically with the vaporization enhancer to achieve the synergistic release of cooling and expansion impact, making the cooling sensation mild and non-irritating. In some implementation methods, it can further enhance the duration of vaporization, extending it by more than 30% compared to traditional single-component agents, and presenting a layered experience of "initial cooling-mid-upward impact-afterward moisturizing", further enhancing the user's inhalation experience.

[0028] In some implementations, the composite cooling agent includes at least two of menthol derivatives, WS-23, WS-3, and N-ethyl-2-isopropyl-5-methylcyclohexaneformamide.

[0029] In some implementations, the menthol derivative is at least one of L-menthol acetate and menthone glycerol ketal.

[0030] In some implementations, vapor-sensory fragrances also include aroma synergists.

[0031] In some implementations, the aroma synergist includes at least one of vanillin, ethyl maltol, allyl hexanoate, and γ-decanoic acid lactone.

[0032] It should be noted that the aroma synergist used in this application can interact with the main aroma components in the atomization matrix to enhance the richness and layering of the aroma. At the same time, its molecular structure can form a weak interaction with the cooling components and vapor enhancement agents to achieve the synchronous release of aroma and vapor, avoiding the problems of "vapor arrival first, aroma lags behind" or "aroma dissipates first, vapor remains".

[0033] In some implementations, vapor-sensory fragrances also include aroma enhancers.

[0034] In some implementations, the aroma enhancer includes at least one of γ-terpinene, α-terpineol, and d-limonene.

[0035] It should be noted that the aroma enhancer used in this application can enhance the permeability and burst of the main aroma in the atomization matrix, and better assist the atomization matrix in simulating the real carbonation in beverages.

[0036] In some implementations, vaporous flavorings also include stabilizers.

[0037] In some implementations, the stabilizer includes at least one of triacetin, monoacetin, and monolaurate.

[0038] It should be noted that the stabilizer used in this application can improve the viscosity stability of the fragrance system, prevent the precipitation and stratification of components under low temperature or long-term storage conditions, and ensure the uniformity of vapor and aroma.

[0039] In some implementations, the solvent includes at least one of food-grade propylene glycol, food-grade glycerin, and polyethylene glycol 400.

[0040] It should be noted that the solvent used in this application must possess good solubility, enabling uniform dispersion of all components, and be fully compatible with the base system of the atomizing matrix to ensure the long-term stability of the vapor-sensory fragrance within the atomizing matrix. Therefore, this application preferably uses at least one of food-grade propylene glycol, food-grade glycerin, and polyethylene glycol 400. It is understood that any solvent meeting the above requirements is suitable for this application, and is not limited to food-grade propylene glycol, food-grade glycerin, and polyethylene glycol 400.

[0041] In some implementations, the vapor-sensory fragrance contains 15-30 parts by weight of a compound cooling agent, 5-15 parts by weight of a vapor-sensory enhancer, 10-20 parts by weight of a fragrance synergist, 0.1-1 parts by weight of a fragrance enhancer, 0.5-3 parts by weight of a stabilizer, and 35-60 parts by weight of a solvent.

[0042] The method for preparing the vapor-sensory fragrance of this application includes the following steps:

[0043] (1) Weigh the solvent and heat it to 30-40℃ while stirring at 100-200r / min for 5-10 minutes; for example, place it in a reaction vessel, heat it to 30-40℃, control the stirring speed at 100-200r / min, and stir for 5-10 minutes.

[0044] (2) Add the vapor enhancement agent while stirring, and continue stirring for 20-30 minutes until completely dissolved.

[0045] In some implementations, where the vapor-sensing flavoring includes a composite cooling agent, the preparation method of this application further includes adding the composite cooling agent at the same time as adding the vapor-sensing enhancer in step (2), and similarly, continuing to stir until the vapor-sensing enhancer and the composite cooling agent are completely dissolved.

[0046] In some implementations, where the vapor-sensory fragrance includes a fragrance synergist, the preparation method of this application further includes, (3) adjusting the temperature to 25-30°C, adding the fragrance synergist, and stirring for 15-20 minutes.

[0047] In some implementations, where the vapor-sensory fragrance includes aroma enhancers and stabilizers, the preparation method of this application further includes (4) adding aroma enhancers and stabilizers at a temperature of 25-30°C, stirring for 30-40 minutes to ensure uniform dispersion of the system and obtain a mixture.

[0048] In some implementations, the preparation method of this application further includes (5) filtering the mixture obtained in step (4), for example, filtering with a filtration accuracy of 0.22 μm to remove impurities and obtain the vapor-scented fragrance of this application.

[0049] In summary, the preparation method of this application is simple, streamlined, and easy to operate, requiring no special or expensive equipment, and is suitable for large-scale industrial production.

[0050] Based on the above research and understanding, this application proposes the application of vapor-sensory flavorings, propylene carbonate, dimethyl carbonate, or γ-butyrolactone in atomizing matrices or electronic atomizing devices.

[0051] Furthermore, this application has developed an atomizing matrix containing the vapor-sensory fragrance of this application, or containing at least one of propylene carbonate, dimethyl carbonate, and γ-butyrolactone.

[0052] Furthermore, this application has developed an electronic atomizing device containing the vapor-sensing flavor of this application, or containing the atomizing matrix of this application, or containing at least one of propylene carbonate, dimethyl carbonate and γ-butyrolactone.

[0053] In some implementations of this application, the vapor-sensory flavoring, the atomizing matrix, or the electronic atomizing device of this application have the following advantages compared with the prior art:

[0054] Long-lasting and layered vapor sensation: It uses a compound cooling agent combined with vapor sensation enhancer to achieve a synergistic release of cooling and expansion impact. The cooling sensation is gentle and non-irritating, and the vapor sensation lasts for more than 30% longer than that of traditional single ingredients. It also presents a layered experience of "initial cooling - mid-puff - after-moistening", enhancing the user's smoking experience.

[0055] Excellent compatibility: The selected raw materials are all compatible with the basic system of the atomization matrix, such as propylene glycol and glycerin. After long-term storage, for example, storage at -10℃ to 45℃ for 6 months, there is no layering, crystallization or precipitation, and the stability is strong.

[0056] High safety: All raw materials are selected according to food-grade standards, comply with relevant industry standards for electronic atomization devices, have no harmful impurities, low irritation, and are suitable for long-term use.

[0057] Excellent aroma synergy: Through the action of aroma synergists, the vapor and aroma are released simultaneously, enhancing the richness and complexity of the aroma, avoiding the problem of vapor and aroma being disconnected, and improving the overall quality of the product.

[0058] The present application will be further described in detail below through specific embodiments. The following embodiments are only for further illustration of the present application and should not be construed as limiting the present application.

[0067] Stabilizer (triacetin): 1.5%.

[0068] Experiment 2: Vapor-scented flavoring, raw material weight percentage:

[0082] II. Performance Testing

[0084] The single menthol vapor-sensing additive is a 40% concentration dilution in propylene glycol. A 50% concentration of menthol in propylene glycol dilution is prone to precipitation at temperatures below 20 degrees Celsius. The industry commonly uses a 40%-45% concentration dilution in propylene glycol.

[0085] Performance tests include: duration of vapor sensation, compatibility, safety, and aroma synergy.

For vapor intensity, cooling sensation level, duration, aroma synergy, and irritation sensory scoring and quantitative scaling, refer to GB / T 39501-2020 "Guidelines for the Use of Quantitative Response Scales for Sensory Analysis".

[0087] III. Results and Analysis

[0088] The test results are shown in Table 1.

[0089] Table 1

[0090] Vapor duration 12-15 s 13-16 s 7-9 s Compatibility (-10℃ to 45℃, 6 months) No layering, no crystallization No layering, no crystallization Stratification occurs after 4 months Irritation (sensory evaluation) Mild and non-irritating Mild and non-irritating Mildly spicy Aroma synergy The aroma and the sensation of vapor are synchronized, creating a rich and complex flavor profile. Aroma and vapor in sync, high intensity The vapor dissipates first, followed by the aroma.

[0091] The results in Table 1 show that the vapor-sensory flavorings prepared in Experiment 1 and Experiment 2 are significantly superior to traditional vapor-sensory additives in terms of vapor duration, compatibility, safety, and aroma synergy.

[0092] Example 2

[0093] Following the same method as in Example 1, different formulations of vaporous flavorings were prepared in this example, as shown in Table 2.

[0094] Table 2

[0095] Experiment 3 5% 30% 20% 41% 1% 3% Experiment 4 15% 15% 10% 59.4% 0.1% 0.5% Experiment 5 15% 30% 17% 35% 0.8% 2.2% Experiment 6 5% 15% 16% 60% 1% 3% Experiment 7 15% 30% 17% 35% 0.8% 2.2% Experiment 8 15% 30% 17% 35% 0.8% 2.2% Experiment 9 15% 30% 17% 35% 0.8% 2.2% Experiment 10 15% 30% 17% 35% 0.8% 2.2% Experiment 11 15% 30% 17% 35% 0.8% 2.2% Experiment 12 15% 30% 17% 35% 0.8% 2.2% Comparison 2 4% 15% 17% 60% 1% 3% Comparison 3 16% 29% 17% 35% 0.8% 2.2% Comparison 4 5% 14% 17% 60% 1% 3% Comparison 5 15% 31% 16% 35% 0.8% 2.2%

[0096] In Table 2, the formulations of Experiments 3 to 6, as well as Comparisons 2 to 5, are the same as those of Experiment 1, except for the different amounts of each component. Specifically, the composite cooling agent is a mixture of L-menthol acetate and WS-23 in a 1:1 ratio, the vapor enhancer is propylene carbonate, the aroma synergist is a mixture of vanillin and ethyl maltol in a 2:1 ratio, the solvent is a mixed solvent of propylene glycol and glycerol in a 3:2 ratio, the aroma enhancer is γ-terpinene, and the stabilizer is triacetin. The vapor-enhancing agent in Experiment 7 was a compound of propylene carbonate: dimethyl carbonate: γ-butyrolactone in a 1:1:1 ratio, with all other components being the same as in Experiment 1; the composite cooling agent in Experiment 8 was a compound of L-menthol acetate: N-ethyl-2-isopropyl-5-methylcyclohexaneformamide in a 1:1 ratio, with all other components being the same as in Experiment 1; the aroma synergist in Experiment 9 was vanillin, with all other components being the same as in Experiment 1; the aroma synergist in Experiment 10 was allyl hexanoate, with all other components being the same as in Experiment 1; the aroma enhancer in Experiment 11 was d-limonene, with all other components being the same as in Experiment 1; and the stabilizer in Experiment 12 was glyceryl monolaurate, with all other components being the same as in Experiment 1.

[0097] The above 10 experimental vaporous flavors and 4 vaporous flavors as controls were prepared in the same manner as in Example 1. The 14 vaporous flavors were tested in the same manner as in Example 1.

[0098] The results showed that the 10 vaporous fragrances from Experiments 3 to 12 had better overall performance in terms of vapor duration, compatibility, safety, and aroma synergy than those from Comparisons 2 to 5. The vapor duration of the 10 vaporous fragrances from Experiments 3 to 12 was between 12 and 17 seconds. Compatibility results showed no layering or crystallization, and the sensory evaluation was mild and non-irritating, presenting a layered experience of "initial coolness - mid-boost - aftertaste." The aroma and vapor were synchronized, with rich layers. Comparison 2, due to a lower dosage of vapor enhancer, had a vapor duration of approximately 9-12 seconds, which was weaker, and the expansion impact was significantly weaker than the experimental group. A small amount of layering appeared in the 6th month, and the synchronization between aroma and vapor was poor. Comparison 3 used a larger dosage of vapor enhancer, but the vapor duration was not significantly enhanced; instead, it remained in the middle range among the experimental groups. The expansion impact and aroma synchronization were not significantly outstanding. Compatibility results showed no layering or crystallization. In summary, increasing the dosage of vapor enhancer did not yield better overall results. Compared to the experimental group, the dosage of the composite cooling agent in group 4 was relatively low, resulting in a weaker cooling sensation and making it difficult to clearly perceive the layered experience of "initial cooling-mid-afterward moisturizing." Other effects were comparable to the experimental group. In contrast, the dosage of the composite cooling agent in group 5 was relatively high. Although the cooling effect was obvious, the synergistic effect with the vapor-enhancing agent was weakened, making its layered experience of "initial cooling-mid-afterward moisturizing" less pronounced than that of the experimental group.

[0099] In summary, a vapor-sensory fragrance formulation consisting of 15-30 parts by weight of a compound cooling agent, 5-15 parts by weight of a vapor-sensory enhancer, 10-20 parts by weight of an aroma synergist, 0.1-1 parts by weight of an aroma enhancer, 0.5-3 parts by weight of a stabilizer, and 35-60 parts by weight of a solvent can achieve a good synergistic effect among the components, resulting in a long-lasting and rich vapor sensation, excellent compatibility, high safety, and good aroma synergy. The vapor-enhancing agent can be one, two, or a combination of three of propylene carbonate, dimethyl carbonate, and γ-butyrolactone; the composite cooling agent can be any two of menthol derivatives, WS-23, WS-3, and N-ethyl-2-isopropyl-5-methylcyclohexaneformamide, wherein the menthol derivative is L-menthol acetate or menthone glycerol ketal; the aroma synergist can be at least one of vanillin, ethyl maltol, allyl hexanoate, and γ-decyl lactone; the aroma enhancer can be at least one of γ-terpinene, α-terpineol, and d-limonene; the stabilizer can be at least one of triacetin, glyceryl monoacetate, and glyceryl monolaurate; and the solvent can be at least one of food-grade propylene glycol, food-grade glycerin, and polyethylene glycol 400.

[0100] The above description, in conjunction with specific embodiments, provides a further detailed explanation of this application and should not be construed as limiting the specific implementation of this application to these descriptions. Those skilled in the art to which this application pertains can make several simple deductions or substitutions without departing from the concept of this application.
