Problems solved by technology

[0010] Although nicotine salts have been widely used in e-cigarette liquids, there are still the following main sensory problems in e-cigarettes containing nicotine salts: when nicotine salts are heated and decomposed to form free nicotine and delivered to the atomized vapor, puff-by-puff nicotine The release behavior is inconsistent with the release behavior of the aromatizing ingredients, and it is difficult to achieve the synergistic delivery of the key aromatizing ingredients and nicotine. While bringing nicotine physiological satisfaction, it cannot bring the matching characteristic fragrance, resulting in the interaction between nicotine and flavoring substances. The sensory sensations are strong and weak, covering each other or even repelling each other, especially for volatile characteristic aroma substances, because they cannot be released stably throughout the smoking process (usually the release amount gradually decreases mouth by mouth), this sense of incongruity especially obvious
Another common problem with e-cigarettes is that during the storage of e-liquid or pods, there will inevitably be a problem of volatilization and loss of flavor components. Even closed pods also have the problem of deterioration of flavor substances.
At present, although microcapsule technology can be used to encapsulate volatile aroma components, since microcapsules mostly use sugars such as cyclodextrin as wall materials, there will be a problem caused by the wall material adhering to the heating element at the heating temperature of the electronic cigarette. burnt smell and discomfort

Embodiment 1

[0076] The preparation method of the gel based on long-chain alkyl dibasic fatty acid nicotine salt gelling agent, comprises the steps:

[0077] Step 1, preparation of gelling agent: dissolve long-chain alkyl dibasic fatty acid and nicotine respectively in the mixed solvent of water and ethanol according to the molar ratio of 2:1, long-chain alkyl dibasic fatty acid and the water and ethanol that dissolve it The mixed solvent mass volume ratio of nicotine is 1g:28mL, the mixed solvent mass volume ratio of nicotine and the water and ethanol that dissolves it is 1g:210mL, stir at room temperature until completely dissolved, and obtain long-chain alkyl dibasic fatty acid solution and nicotine respectively Solution, and then the above two solutions are fully mixed to obtain a mixed solution, the mixed solution is heated to reflux, reacted for more than 30 minutes, 160mbar, 53 ° C, and then the product obtained by the rotary evaporation was dried at 36 ° C for 24 hours, The long-ch...

Embodiment 2

[0083] This example provides the application of the supramolecular gel prepared in Example 1 of the present invention in heating cigarettes

[0084] The nicotine salt supramolecular gel can be respectively applied in the manufacturing process of the reconstituted tobacco leaves for paper-making heated cigarettes and the reconstituted tobacco leaves for thick-pulp heated cigarettes, and a single gel or different types of mixed gels can be applied according to actual conditions.

[0085] Reconstituted tobacco leaves for paper-making heated cigarettes:

[0086] Method 1: Add the supramolecular gel prepared in Example 1 to a certain amount of fuming agent (1,2-propylene glycol, glycerin or a mixture of the two in a certain proportion), and the mass ratio of supramolecular gel to smoking agent is 6: 1. When the temperature is raised to 65°C, the gel melts into a sol state or a solution, and is uniformly mixed to form a mixed coating liquid containing molten gel and fuming agent. Th...

Embodiment 3

[0098] This example provides the application of the supramolecular gel prepared in Example 1 in electronic cigarettes.

[0099] The nicotine salt supramolecular gel can be applied in electronic cigarettes in two ways, and a single gel or different types of mixed gels can be used according to actual conditions.

[0100] Method 1: Dry the supramolecular gel prepared in the above example 1 in an oven at 40°C for 24-36 hours at a constant temperature, grind the dried gel into uniform micro-particles, and add a certain amount of e-cigarette smoke in a certain proportion Fully stir in the fuming agent, the fuming agent is a mixed solvent of glycerin and 1,2-propylene glycol 1:1 (volume ratio), the mass ratio of the supramolecular gel to the fuming agent is 1:120, and after mixing evenly, it will be used as a fragrance-containing gel The gel smoke agent or as an auxiliary material is directly added to the finished e-liquid and mixed evenly as a gel e-liquid containing fragrance.

Abstract

The invention belongs to the field of supramolecular gels, and particularly relates to a gel based on a long-chain alkyl binary fatty acid nicotine salt gelling agent. The gel comprises the long-chain alkyl binary fatty acid nicotine salt gelling agent, and a flavor substance and a solvent dispersed in the long-chain alkyl binary fatty acid nicotine salt gelling agent. The gelling agent with a supramolecular network structure and a supramolecular gel are prepared from the long-chain alkyl binary fatty acid and the nicotine for the first time; and the flavor substance is stably fixed in the gel network at normal temperature, so that the storage stability of the flavor substance is effectively improved, and common fixation and synergistic release of nicotine and the flavor substance are realized.

Description

technical field [0001] The invention belongs to the field of supramolecular gels, in particular to gels based on long-chain alkyl dibasic fatty acid nicotine salt gelling agents. Background technique [0002] Basic nicotine can react with carboxyl groups of organic acids to form nicotine carboxylate. Nicotine contains a pyridine ring and a pyrrole ring. Among them, the pyrrole ring nitrogen is more basic and tends to react with the carboxyl group of a carboxylic acid to form nicotine salts, while the pyridine ring nitrogen is weaker in basicity and cannot ionize basically. Binds to carboxylic acids through non-covalent interactions such as hydrogen bonds. Tobacco leaves naturally contain various carboxylic acid nicotine salts. According to the acid-base ratio of nicotine salts, nicotine salts can be divided into 1:1 acid-base ratio, 2:1 acid-base ratio, and 3:1 acid-base ratio nicotine salt. Among them, common nicotine carboxylates include nicotine tartrate, long-chain alk...
