Description

Technical Field

[0001] The present application relates to the technical field of cigarette holder filters and cigarette filter tips, and in particular to a composition having the function of reducing the harm of cigarette smoke, and a preparation method and application thereof. Background Art

[0002] Cigarettes contain a variety of harmful substances, including nicotine, carbon monoxide, tar, heavy metals and a variety of carcinogens. Smoking is the main cause of heart disease, stroke, peripheral artery disease and chronic obstructive pulmonary disease (COPD).

[0003] In addition, smoking is also associated with respiratory diseases such as pneumonia and asthma. Smoking is also associated with many types of cancer, the most common of which is lung cancer; these diseases are closely related to heavy metals. Although cigarettes have built-in filters that can filter out some harmful substances, their effect is extremely limited.

[0004] Therefore, there is an urgent need for a composition that can reduce the harm of cigarette smoke. Summary of the invention

[0005] The purpose of the present application is to overcome the shortcomings of the above-mentioned prior art and provide a composition with the function of reducing the harm of cigarette smoke and its preparation method and application. The composition of the present application can reduce the inhalation of harmful substances such as harmful heavy metals and tar in the smoke, thereby reducing the incidence of various diseases induced by smoking and improving the health of smokers.

[0006] To achieve the above purpose, the technical solution adopted by this application is:

[0007] The present application provides a composition having the function of reducing the harm of cigarette smoke, the composition comprising the following components: a chelating agent, an adsorbent, a stabilizer and a masking agent;

[0008] The chelating agent is at least one of GMDTC, lipoic acid, and sodium diethyldithiocarbamate;

[0009] The adsorbent is at least one of zeolite, graphene, and starch porous materials;

[0010] The stabilizer includes at least one of sodium citrate, ammonia water, and sodium carbonate;

[0011] The masking agent includes fragrance.

[0012] In the technical scheme of the present application, the composition of the present application includes a chelating agent, an adsorbent, a stabilizer and a masking agent, wherein the above-mentioned types of chelating agents, adsorbents and stabilizers are used in combination to effectively adsorb heavy metals and tar, reduce harmful substances in smoke, and reduce the incidence of various diseases induced by smoking. The composition formed by the combination of the above-mentioned components is significantly better than the combination of chelating agents, stabilizers and adsorbents in pairs in reducing the content of total solid phase, tar, cadmium, arsenic and lead.

[0013] Experiments have shown that when the chelating agent is at least one of GMDTC, lipoic acid, and sodium diethyldithiocarbamate, the removal of heavy metals is better than that of other chelating agents (such as EDTA).

[0014] As a preferred embodiment of the composition having the function of reducing the harm of cigarette smoke described in the present application, the composition comprises the following components in parts by weight:

[0015] 20 to 70 parts of chelating agent, 10 to 70 parts of adsorbent, 10 to 30 parts of stabilizer and 0.001 to 0.01 parts of masking agent.

[0016] The composition of the present application adopts the above components in parts by weight, which can effectively reduce the total solid phase, tar, cadmium, arsenic and lead content in the flue gas.

[0017] As a preferred embodiment of the composition having the function of reducing the harm of cigarette smoke described in the present application, the composition comprises the following components in parts by weight:

[0018] 20 to 50 parts of chelating agent, 10 to 50 parts of adsorbent, 10 to 20 parts of stabilizer and 0.001 to 0.008 parts of masking agent.

[0020] As a preferred embodiment of the composition having the function of reducing the harm of cigarette smoke described in the present application, the chelating agent is GMDTC; and the adsorbent is a porous starch material.

[0021] The present application prefers the above-mentioned types of chelating agents and adsorbents, which can better adsorb heavy metals and tar in flue gas and reduce the total solid phase, tar, cadmium, arsenic and lead content in flue gas.

[0022] As a preferred embodiment of the composition having the function of reducing the harm of cigarette smoke described in the present application, the flavor includes mint flavor or lemon flavor.

[0023] As a preferred embodiment of the composition having the function of reducing the harm of cigarette smoke described in the present application, the method for preparing the porous starch material comprises the following steps:

[0024] The starch and GMDTC are sintered at 250-450° C. for 2-12 hours under a nitrogen atmosphere to obtain a porous starch material;

[0025] The mass ratio of the starch to GMDTC is (5-10):(1-5).

[0026] GMDTC can be vaporized at high temperature to form a pore structure of suitable size. The starch porous material prepared in the present application can generate adsorption force by weak valence of atoms or atomic groups to adsorb substances. Because it has concave holes, the adsorbate can be sucked into the inner wall of the hole, the adsorption is relatively firm, and the adsorbate is not easy to fall off. Therefore, the above starch porous material is used in the present application to better adsorb heavy metals and tar in flue gas.

[0027] Furthermore, the present application adopts the above-mentioned chelating agent, adsorbent and stabilizer compound, which can better reduce the total solid phase, tar, cadmium, arsenic and lead content in the flue gas, and effectively adsorb heavy metals and tar.

[0028] The present application also provides a method for preparing the above-mentioned composition having the function of reducing the harm of cigarette smoke. The composition having the function of reducing the harm of cigarette smoke is obtained by uniformly mixing the chelating agent, adsorbent, stabilizer and masking agent, and then freeze-drying or drying the mixture.

[0029] The present application also provides the use of the above-mentioned composition having the function of reducing the harm of cigarette smoke in a cigarette holder filter.

[0030] Compared with the prior art, this application has the following beneficial effects:

[0031] The present application provides a composition with the function of reducing the harm of cigarette smoke, and its preparation method and application. The composition of the present application is compounded with a chelating agent, an adsorbent, a stabilizer and a masking agent, and can reduce the inhalation of harmful heavy metals, tar and other harmful substances in the smoke, specifically reducing the total solid phase, tar, cadmium, arsenic and lead content in the smoke, reducing the incidence of various diseases induced by smoking, and improving the health of smokers.

[0087] Test example, calculated composition of cigarette smoke

[0088] The determination of arsenic, lead, cadmium and mercury in smoke was carried out in accordance with the standards of the Chinese tobacco industry. The total particulate matter and tar in cigarette smoke were first captured by a smoking machine, and then the arsenic, lead, cadmium and mercury content in the total particulate matter was determined by inductively coupled plasma mass spectrometry (ICP-MS), and then converted into the release of arsenic, lead, cadmium and mercury in the mainstream smoke of each cigarette. A cigarette of the same specification without the composition added to the filter rod was used as a control.

[0089] Comparison was made by calculating cigarette smoke from disposable mouthpiece filters or popping beads using the added composition and comparing them with control samples.

[0090] As shown in Table 1.

[0091] Table 1

[0092]

[0093] According to the data in Table 1, the composition for reducing the harm of cigarette smoke provided by the present application, when the chelating agent in the composition of the present application is one of GMDTC, lipoic acid, and sodium diethyldithiocarbamate, is better than EDTA in removing heavy metals (Comparative Example 4).

[0094] When the composition of the present application uses zeolite, graphene, starch porous material as the adsorbent, it is superior to other types of adsorbents in reducing the total solid phase, tar, cadmium, arsenic, and lead content (Comparative Example 5).

[0095] Furthermore, according to Examples 1 and 2, it can be seen that when the adsorbent is a porous starch material, the effect is better than that of zeolite.

[0096] The compositions for reducing the harm of cigarette smoke provided in Examples 1 to 8 of the present application use a combination of a chelating agent, a stabilizer and an adsorbent to reduce the total solid phase, tar, cadmium, arsenic and lead content, which is significantly better than the combination of a chelating agent, a stabilizer and an adsorbent in pairs (Comparative Examples 1 to 3).

[0097] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present application rather than to limit the scope of protection of the present application. Although the present application has been described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the present application can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the present application.
