Description

Technical Field

[0001] The present application relates to the technical field of electronic cigarettes, and in particular to a dissolving agent and its application in electronic cigarette oil. Background Art

[0002] Electronic cigarettes produce smoke by atomizing e-liquid. Compared with the inhalation of traditional cigarettes, they can not only bring consumers a better smoking experience, but also do not produce harmful substances such as carbon monoxide and tar. They are gradually gaining favor among consumers at home and abroad.

[0003] The main components of e-cigarette oil are propylene glycol, glycerin, nicotine, acidulants, sweeteners, cooling agents and flavors. Propylene glycol acts as a solvent to dissolve flavors and other ingredients; glycerin is the main atomizer of e-cigarette oil, and its function is to produce smoke. Sweeteners, acidulants, cooling agents and flavors in e-cigarette oil can enrich the taste and flavor of e-cigarettes and increase the fun and experience of users using e-cigarettes. However, since the composition of flavors of different flavors is different, and the characteristic monomers contained in some flavors are not miscible with glycerin, some components may not be miscible with the system during the preparation or storage of the oil, which is called floating oil. Floating oil will cause problems such as uneven taste, odor or sticky core in e-cigarettes.

[0004] Therefore, how to reduce or eliminate floating oil is an urgent problem to be solved in order to improve the taste of e-cigarettes. Summary of the invention

[0005] The present application provides a dissolving agent and its application in electronic cigarette oil, aiming to solve the problem that existing electronic cigarette oil is prone to produce floating oil, which affects the taste of the electronic cigarette.

[0006] To achieve the above purpose, the present application proposes a dissolving agent, which comprises, by weight, 0.1 to 0.5 parts of polyethylene glycol monooleate, 0.1 to 0.5 parts of caprylic acid capric acid macrogol glyceride, and 0.5 to 1 part of propylene glycol.

[0011] In some embodiments, the composition comprises, by weight: 0.4 parts of polyethylene glycol monooleate, 0.2 parts of caprylic / capric macrogol glycerides, 0.02 parts of Tween 20 and 0.9 parts of propylene glycol.

[0012] In some embodiments, the composition comprises, by weight: 0.5 parts of polyethylene glycol monooleate, 0.1 parts of caprylic / capric macrogol glycerides, 0.05 parts of Tween 20 and 1 part of propylene glycol.

[0013] The present application also proposes a use of the above-mentioned solvent in electronic cigarette oil.

[0014] The technical solution of the present application proposes a dissolving agent and its application in electronic cigarette oil. The dissolving agent comprises, by weight: 0.1-0.5 parts of polyethylene glycol monooleate, 0.1-0.5 parts of caprylic capric acid polyethylene glycol glyceride and 0.5-1 parts of propylene glycol. The technical solution of the present application provides a dissolving agent, in which each component of the dissolving agent is a tasteless and low-taste substance, which will not produce additional odor or impurities when added to the oil, and each component has good dissolving, emulsifying or dispersing properties, and the combined effect can significantly improve the stability of the oil, making it difficult for the oil to stratify, thereby effectively reducing or eliminating floating oil. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] In order to more clearly illustrate the embodiments of the present application or the technical solutions in the prior art, the drawings required for use in the embodiments or the prior art descriptions are briefly introduced below. Obviously, the drawings described below are only some embodiments of the present application. For those of ordinary skill in the art, other drawings can be obtained based on these drawings without creative work, among which:

[0016] Figure 1 This is a state diagram of the electronic cigarette atomizer after use in this application. Figure 1 In the figure, (a) is a schematic diagram (rough schematic diagram) of the state of the core being burnt after the use of the electronic cigarette atomizer of the comparative example of the present application, and (b) is a schematic diagram (rough schematic diagram) of the state of the core not being burnt after the use of the electronic cigarette atomizer of the embodiment of the present application. DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0018] See also Figure 1 As shown, the present application proposes a dissolving agent, which comprises, by weight, 0.1 to 0.5 parts of polyethylene glycol monooleate, 0.1 to 0.5 parts of caprylic acid capric acid macrogol glyceride, and 0.5 to 1 part of propylene glycol.

[0019] Specifically, polyethylene glycol monooleate is a non-ionic surfactant with good dispersing and emulsifying properties. It can help different components in the e-liquid to mix better and reduce stratification; adding a proper amount can enhance the stability of the e-liquid without introducing too much odor.

[0020] Caprylic / capric acid macrogol glyceride is an ester compound with excellent solubility and emulsification. It can help the oily components in the e-liquid to be better dispersed in the solvent to prevent the floating oil phenomenon; this ingredient also helps to improve the taste of the e-liquid and make it softer.

[0021] Propylene glycol is one of the commonly used solvents in e-cigarette oils, with good solubility and volatility. It can help dissolve other ingredients in the oil and produce the desired smoke effect; adding a proper amount of propylene glycol can also adjust the taste and smoke volume of the oil to make it more in line with the user's taste.

[0022] In some embodiments, the dissolving agent further comprises 0.01 to 0.05 parts by weight of Tween 20. Tween 20 is a nonionic surfactant with strong emulsification, dispersion and penetration capabilities. Adding a small amount of Tween 20 to the e-liquid can significantly improve the uniformity and stability of the e-liquid; at the same time, it can also reduce the clogging and corrosion of the e-cigarette device by the e-liquid during use, thereby extending the service life of the device.

[0023] Therefore, in the formula of the solvent, each component is odorless or low-odor substance, and will not produce additional odor or impurities after being added to the e-liquid; and they can work together to significantly improve the stability of the e-liquid, making it difficult to stratify even after being placed for a long time, and reduce or eliminate the floating oil phenomenon. In addition, the emulsifier and surfactant in the solvent can improve the taste of the e-liquid, making it smoother and more delicate; and by optimizing the ratio and dispersibility of the components with the e-liquid, it can effectively reduce the phenomenon of the e-cigarette core being burnt and bitter during use.

[0024] Among them, the dissolving agent proposed in the present application only needs to be prepared according to the proportion, and each component is placed in a special food mixer and stirred and mixed evenly under certain stirring parameters, and then left to stand for a period of time to obtain. For example, the stirring speed is controlled to be 100 to 1400 rpm, stirred at room temperature for 15 to 25 minutes, and left to stand for 1.5 to 2.5 hours. The preparation process is simple and convenient.

[0025] Furthermore, during the preparation process, the ratio of each component can be adjusted to achieve the best ratio to achieve the best stability and taste effect. Exemplarily, the dissolving agent has the following ratio:

[0026] 1) The dissolving agent comprises, by weight: 0.1 part of polyethylene glycol monooleate, 0.5 part of caprylic acid capric acid macrogol glyceride, 0.01 part of Tween 20 and 0.5 part of propylene glycol.

[0027] 2) The dissolving agent comprises, by weight: 0.2 parts of polyethylene glycol monooleate, 0.3 parts of caprylic and capric macrogol glycerides, 0.02 parts of Tween 20 and 0.6 parts of propylene glycol.

[0028] 3) The dissolving agent comprises, by weight: 0.3 parts of polyethylene glycol monooleate, 0.2 parts of caprylic and capric macrogol glycerides, 0.02 parts of Tween 20 and 0.8 parts of propylene glycol.

[0029] 4) The dissolving agent comprises, by weight: 0.4 parts of polyethylene glycol monooleate, 0.2 parts of caprylic and capric macrogol glycerides, 0.02 parts of Tween 20 and 0.9 parts of propylene glycol.

[0030] 5) The dissolving agent comprises, by weight: 0.5 parts of polyethylene glycol monooleate, 0.1 parts of caprylic and capric macrogol glycerides, 0.05 parts of Tween 20 and 1 part of propylene glycol.

[0031] The above-mentioned proportioning methods are only some embodiments of the present application. Any modifications made within the parameter range proposed in the present application are within the protection scope of the present application.

[0032] The present application further proposes an application of the above-mentioned dissolving agent in electronic cigarette oil. The relevant electronic cigarette oil is prepared in advance, and exemplary includes:
