Description
Technical Field
The invention belongs to the technical field of electronic cigarettes, and particularly relates to an atomization agent for cigarettes and electronic cigarette liquid.
Background
In recent years, along with the continuous increase of the international and domestic smoke control force, various low-temperature non-combustion tobacco products are developed successively. The electronic cigarette simulates the smoking experience of real cigarettes, does not burn at high temperature, reduces the release of a plurality of harmful substances, and is favored by consumers.
At present, electronic cigarette manufacturers have developed electronic cigarette liquids with various tastes, the main components of the main stream electronic cigarette liquid in the market are a mixture of edible or medical glycerol, propylene glycol and tobacco special essence, and certain electronic cigarette oils also contain nicotine and tobacco extract components, mainly for enabling the taste of the electronic cigarette liquids to be more similar to cigarettes. Patent number CN 111938197A discloses an electronic cigarette tobacco tar, comprising propylene glycol and vegetable glycerin, wherein the throat feeling of the tobacco tar is reduced by adjusting the proportion of the propylene glycol and the vegetable glycerin; chinese patent CN109864330a discloses an electronic cigarette liquid containing polyol, which comprises at least one of pentatriol and butanetriol, and solves the problems of sweet and greasy feel and heavy dry feel of propylene glycol and glycerin during suction by adopting polyol to replace propylene glycol and glycerin in the traditional electronic cigarette liquid as atomization fuming agents; the electronic cigarette atomizer disclosed in CN104473323A comprises an ester compound, water, propylene glycol and/or glycerin, and the unique taste characteristics of the large molecular weight esters are utilized to screen and optimize the combination ratio of the large molecular weight esters, so that the electronic cigarette atomizer can be used as the electronic cigarette atomizer independently and can be matched with the existing atomizer. Through experimental evaluation and suction, the electronic cigarette aerosol has good taste, and can obviously overcome the sweet greasy feeling caused by the large amount of glycerol and propylene glycol used in the existing aerosol.
The electronic cigarette aerosol or the electronic cigarette liquid mainly takes the aroma, the fragrance and the taste as main directions, and the problems of fog forming capability and the release of the amount of the fog are ignored. Therefore, in the formula of the electronic cigarette aerosol, the further scientific selection of the formula combination with low boiling point, low atomizing temperature, large atomizing amount and no obvious sweet and greasy feeling and dry feeling is particularly important.
Disclosure of Invention
In order to solve the technical problems, the invention aims to provide an atomization agent for cigarettes and electronic cigarette liquid. The smoke atomizer contains low-boiling-point glyceroglycosides, and can reduce atomization temperature and improve smoke release amount when being added into electronic cigarette liquid.
In order to achieve the above object, the present invention provides an aerosol for cigarettes, comprising 9 to 11 parts by mass of glycerol glucoside, 40 to 60 parts by mass of propylene glycol and 10 to 30 parts by mass of glycerol.
The glyceroglycosides are alkyl glycoside substances, are prepared from glycerol and glucose through glycosylation reaction, and have 6-medium three-dimensional structures according to different three-dimensional structures and glycosidic bond connection positions, and have the following structural formulas:
glycerol glucosides of different configurations
The glyceroglycosides belong to a common compound in the polyol glycoside, and are mainly used as a humectant, a surfactant and the like. It has the functions of moisture absorption and moisture preservation, and has low toxicity and low irritation, and is also widely applied to the fields of medicines, cosmetics, health products, food additives and the like. However, the inventor of the present application unexpectedly found that, by adding the glycerol glucoside having a low boiling point as an atomizing agent to the electronic cigarette liquid, rapid atomization at a low heating temperature can be achieved, and a large amount of smoke releasing effects can be produced, so that the smoking experience of consumers can be satisfied, and thus, the present invention has been created.
The glyceroglycosides can be independently used as an electronic cigarette atomizer, and can also be matched with the existing atomizer for use. However, due to the fact that the viscosity of the glyceroglycosides is high, the fluidity of the electronic cigarette liquid can be affected when the glyceroglycosides are used alone, so that tobacco tar can not be timely supplemented to the vicinity of a heating wire to be heated, and the fogging capacity is reduced. Thus, the aerosol further comprises 40-60 parts propylene glycol and 10-30 parts glycerin. Propylene glycol and glycerol not only play a role in diluting glyceroglycosides, but also are easy to gasify in the electronic cigarette due to low boiling point, and the gasified smoke has good diffusivity and fullness in the oral cavity and the nasal cavity, and the glycerol can enable the smoke to be thick and full, so that the atomization effect can be further improved.
In order to obtain better blending effect and atomizing agent fluidity, as a further scheme of the invention, the viscosity of the glyceroglycosides is 56 mPas-894 mPas.
The preparation process of the glyceroglycosides is not limited, and a direct glycosylation method, a solvent method, a transglycosidation method, an indirect synthesis method, an enzyme catalysis method and the like can be adopted. As a further scheme of the invention, the glyceroglycosides are obtained by mixing glycerol, glucose and an acidic catalyst and then carrying out thermal reflux. Under the condition of an acid catalyst, the glycerol and the glucose are directly reacted to generate the catalyst, the reaction steps are simple, the reaction conditions are mild, and no chemical solvent is remained.
The commonly used acid catalyst is hydrochloric acid, sulfuric acid, phosphoric acid and other liquid acid, which has the problems of poor selectivity, more byproducts, poor product quality, serious equipment corrosion and the like, and a large amount of acid wastewater can not be recovered, thus being easy to cause environmental pollution. As a further scheme of the invention, the acid catalyst is an acid active carbon supported catalyst, and the catalyst has the advantages of mild reaction, no corrosion to equipment, less pollution, solid state and easy recovery; in addition, the glycerol glucoside prepared by using the catalyst has no byproducts, so that the influence of impurities generated by side reactions in the glycerol glucoside on the suction quality is avoided when the glycerol glucoside is used as an atomizing agent.
The activated carbon can be loaded with various acidic compounds as an acidic catalyst, and the p-toluenesulfonic acid basically has the advantage of sulfuric acid, is an organic acid, has weak oxidizing property, does not cause corrosion and has little pollution. As a further scheme of the invention, the acidic activated carbon supported catalyst is an activated carbon supported p-toluenesulfonic acid catalyst.
As a further scheme of the invention, the molar ratio of the glycerol to the glucose is (10:1) - (2:1), for example, the glycerol can be 2:1,3:1,4:1,5:1,6:1,7:1,8:1,9:1,10:1 and the like, and the excess glycerol not only promotes the reaction process, so that the glucose reaction is more complete, but also can directly serve as an atomizing agent component without removing the excess glycerol raw material after the reaction is finished, therefore, the preparation of the glycerol glucose only needs to filter and remove the solid catalyst, and the excess glycerol is not required to be removed, thereby avoiding the strict post-treatment processes such as column chromatography, distillation and the like.
As a further scheme of the invention, the mass ratio of the acid catalyst to the glucose is (0.02:1) - (0.03:1).
As a further scheme of the invention, the reflux temperature of the thermal reflux is 90-150 ℃ and the reflux time is 4-5h.
In addition, the invention also provides an electronic cigarette liquid which comprises the aerosol for cigarettes.
As a further scheme of the invention, the electronic cigarette liquid comprises 60-80 parts of the atomizing agent, 0.01-0.2 part of nicotine and 1-10 parts of tobacco flavor in parts by mass.
The glyceroglycosides are synthesized by a chemical method under the condition of an acid catalyst, and the reaction conditions are mild, quick and efficient, and the post-treatment is simple. The synthesized glyceroglycosides have low boiling point, can be singly used as an electronic cigarette atomizing agent, can be matched with the existing traditional atomizing agent for use, can generate larger smoke quantity at a lower temperature, further improve the suction taste of the electronic cigarette, and meet the sensory requirements of consumers. In addition, by reasonably preparing the proportion between the glycerol glucoside and the propylene glycol and the glycerol, the glycerol glucoside, the propylene glycol and the glycerol are alcoholized, a series of elegant aroma can be endowed to the smoke liquid by degradation, the aroma quantity is increased, especially the sweet spot generated by degradation can also increase the salivation and sweetness of the oral cavity during suction, so that the use amount of the propylene glycol and the glycerol in the traditional atomizing agent is reduced, and the sweet greasy feeling is reduced.
Compared with the prior art, the invention has the following beneficial effects:
1. the smoke atomizer provided by the invention contains the glyceroglycosides, so that the smoke atomizer can be directly atomized at the heating temperature of the electronic cigarette, and has the advantages of no high boiling point substance residue, low atomization temperature and good atomization effect.
2. According to the invention, by reasonably blending the proportion of the glyceroglycosides, the propylene glycol and the glycerol, the proper viscosity of the atomizing agent is obtained, so that the atomizing agent flows to the heating element in time, and the continuous atomizing capability is improved; and the glyceroglycosides can be alcoholized, degrade and release characteristic aroma, and produce good perfuming effect.
3. The invention prepares the glyceroglycosides by a chemical synthesis method under the condition of an acid catalyst, improves the yield of the glyceroglycosides, and has the advantages of green and environment-friendly preparation method and no complex post-treatment process.
4. The components in the aerosol for cigarettes provided by the invention are food-grade additives, are harmless to health of smokers, and are beneficial to popularization and use in electronic cigarette liquid.
