Description

Technical Field

[0001] The present invention relates to the technical field of cooling agents, and in particular to a composite cooling agent, an electronic cigarette atomizing liquid and an electronic cigarette. Background Art

[0002] Cooling agents are a class of chemical substances that can produce a cooling effect and are not very medicinal. Their use in electronic atomizing liquid is intended to provide a taste experience different from that of traditional cigarettes. Unlike the bitterness that may be brought by traditional cigarettes and original e-cigarette oils, cooling agents can provide a pure cooling feeling without bitterness, spiciness, burning or numbness.

[0003] At present, in the electronic atomization liquid market, the commonly used cooling agents are WS-3, WS-23, WS-5, menthol, etc. The various cooling agents act on different parts of the body. WS-3 mainly brings a cooling sensation in the throat, WS-23 mainly brings a cooling sensation in the mouth, and WS-5 mainly brings a cooling sensation in the nasal cavity. Although menthol can bring an overall cooling experience, it will bring a bitter feeling when added in large amounts. Although traditional cooling agents can bring a cooling sensation, their effects are slightly single. Summary of the invention

[0004] The main purpose of the present invention is to provide a composite cooling agent, aiming to overcome the problem of the single cooling effect of the cooling agent in the prior art.

[0005] To achieve the above object, the present invention provides a composite cooling agent, which comprises the following raw material components:

[0006] N,2,3-Trimethyl-2-isopropylbutyramide, caraway seed oil, carveol, white thyme oil, menthyl isovalerate, 1,4-cineole, and cis-3,3,5-trimethylcyclohexanol.

[0007] In one embodiment, the composite cooling agent comprises the following components in parts by mass:

[0008] 50-75 parts of N,2,3-trimethyl-2-isopropylbutyramide;

[0009] Caraway oil 0.03-0.07 parts;

[0010] Carveol 0.1-0.5 part;

[0011] 0.02-0.05 parts of white thyme oil;

[0012] Menthyl isovalerate 0.1-1 part;

[0013] 0.05-0.1 parts of 1,4-cineole; and

[0014] 0.1 to 0.3 parts of cis-3,3,5-trimethylcyclohexanol.

[0015] The present invention also provides an electronic cigarette atomizing liquid, comprising the above-mentioned composite cooling agent.

[0016] In one embodiment, in the electronic cigarette atomizer liquid, the mass proportion of the composite cooling agent is 3% to 8%.

[0017] In one embodiment, the electronic cigarette atomizing liquid further includes an atomizing agent.

[0018] In one embodiment, the aerosol agent comprises glycerin and propylene glycol.

[0019] In one embodiment, the mass ratio of the propylene glycol to the glycerol is 1:(0.9-1.1).

[0020] The present invention also provides an electronic cigarette, comprising the electronic cigarette atomizing liquid.

[0021] In the technical solution provided by the present invention, N,2,3-trimethyl-2-isopropylbutanamide is also called WS-23. The cooling effect of WS-23 is long-lasting and refreshing, and can maintain the cool taste of the product for a long time; the cooling feeling of WS-23 is mainly concentrated in the front of the tongue and mouth, which can provide a cool feeling in the oral cavity, but it does not significantly improve the cool feeling in the throat and nasal cavity. Caraway oil is an essential oil obtained from the fruit of caraway seeds by steam distillation. It has the characteristics of spicy, warm and sweet, with a minty aroma. This aroma is used in combination with WS-23 to enhance the sensory experience of the throat and bring a cool feeling to the throat. Carveol comes naturally from a variety of plants such as parsley and celery, has anti-inflammatory properties, can provide an overall cool feeling and increase hair permeability. White thyme oil is an essential oil extracted from thyme plants, also known as thyme oil. It contains a variety of active ingredients such as thymol and carvacrol, and has multiple biological activities such as antibacterial, antiseptic, and antioxidant. Thyme oil not only has a unique and clean aroma, similar to mint, but also can bring people a significant cooling feeling and oral sweetness. Menthyl isovalerate not only has a significant cooling feeling, can quickly reduce the local temperature, and bring a refreshing feeling, but also has a unique cool fragrance, mint fragrance, woody fragrance and fruity fragrance. These fragrances can improve the sensory quality of the product and increase the oral sweetness. 1,4-Cineole is a naturally occurring oxygenated monoterpene, mainly found in plants such as Cubeb and Anthemis nobilis. It has a unique cooling fragrance, which can not only quickly bring a cooling feeling to users, provide a fresh mint fragrance, but also increase the oral sweetness. Cis-3,3,5-trimethylcyclohexanol can provide a cool fragrance and a minty sweet fragrance, which can improve the cooling feeling of the mouth, throat and nasal cavity. Therefore, through the combination of the above-mentioned substances, the composite cooling agent can have a refreshing cooling fragrance, a slightly fresh floral fragrance and a slightly sweet fragrance in terms of olfactory aroma; in terms of sensory absorption, it has a rich cooling sensation, a clean aftertaste, a slightly minty fresh aroma, and a slightly sweet aftertaste in the mouth; thus, when applied to electronic cigarette atomization liquid, it has a significant effect in highlighting the cooling taste of electronic atomization. DETAILED DESCRIPTION

[0022] To make the purpose, technical scheme and advantages of the embodiment of the present invention clearer, the technical scheme in the embodiment of the present invention will be described clearly and completely below. If the specific conditions are not specified in the embodiment, it is carried out according to the normal conditions or the conditions recommended by the manufacturer. If the reagents or instruments used do not specify the manufacturer, they are all conventional products that can be purchased commercially. In addition, the meaning of "and / or" appearing in the full text includes three parallel schemes, taking "A and / or B" as an example, including scheme A, or scheme B, or schemes that A and B meet at the same time. In addition, the technical schemes between the various embodiments can be combined with each other, but must be based on the ability of ordinary technicians in the field to achieve. When the combination of technical solutions is contradictory or cannot be achieved, it should be considered that the combination of such technical solutions does not exist, and is not within the scope of protection required by the present invention. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in the field without making creative work belong to the scope of protection of the present invention.

[0023] Cooling agents are a class of chemical substances that can produce a cooling effect and are not very medicinal. Their use in electronic atomizing liquid is intended to provide a taste experience different from that of traditional cigarettes. Unlike the bitterness that may be brought by traditional cigarettes and original e-cigarette oils, cooling agents can provide a pure cooling feeling without bitterness, spiciness, burning or numbness.

[0024] At present, in the electronic atomization liquid market, the commonly used cooling agents are WS-3, WS-23, WS-5, menthol, etc. The various cooling agents act on different parts of the body. WS-3 mainly brings a cooling sensation in the throat, WS-23 mainly brings a cooling sensation in the mouth, and WS-5 mainly brings a cooling sensation in the nasal cavity. Although menthol can bring an overall cooling experience, it will bring a bitter feeling when added in large amounts. Although traditional cooling agents can bring a cooling sensation, their effects are slightly single.

[0025] In view of this, the present invention proposes a composite cooling agent, aiming to overcome the problem of the single cooling effect of cooling agents in the prior art. The raw material components of the composite cooling agent include N,2,3-trimethyl-2-isopropylbutyramide, caraway oil, carveol, white thyme oil, menthyl isovalerate, 1,4-cineole and cis-3,3,5-trimethylcyclohexanol.

[0026] In the technical solution provided by the present invention, N,2,3-trimethyl-2-isopropylbutanamide is also called WS-23. The cooling effect of WS-23 is long-lasting and refreshing, and can maintain the cool taste of the product for a long time; the cooling feeling of WS-23 is mainly concentrated in the front of the tongue and mouth, which can provide a cool feeling in the oral cavity, but it does not significantly improve the cool feeling in the throat and nasal cavity. Caraway oil is an essential oil obtained from the fruit of caraway seeds by steam distillation. It has the characteristics of spicy, warm and sweet, with a minty aroma. This aroma is used in combination with WS-23 to enhance the sensory experience of the throat and bring a cool feeling to the throat. Carveol comes naturally from a variety of plants such as parsley and celery, has anti-inflammatory properties, can provide an overall cool feeling and increase hair permeability. White thyme oil is an essential oil extracted from thyme plants, also known as thyme oil. It contains a variety of active ingredients such as thymol and carvacrol, and has multiple biological activities such as antibacterial, antiseptic, and antioxidant. Thyme oil not only has a unique and clean aroma, similar to mint, but also can bring people a significant cooling feeling and oral sweetness. Menthyl isovalerate not only has a significant cooling feeling, can quickly reduce the local temperature, and bring a refreshing feeling, but also has a unique cool fragrance, mint fragrance, woody fragrance and fruity fragrance. These fragrances can improve the sensory quality of the product and increase the oral sweetness. 1,4-Cineole is a naturally occurring oxygenated monoterpene, mainly found in plants such as Cubeb and Chamomile. It has a unique cooling fragrance, which can not only quickly bring a cooling feeling to users, provide a fresh mint fragrance, but also increase the oral sweetness. Cis-3,3,5-trimethylcyclohexanol can provide a cool fragrance and a mint-like sweet fragrance, which can improve the cooling feeling of the mouth, throat and nasal cavity. Therefore, through the combination of the above-mentioned substances, the composite cooling agent can have a refreshing cooling fragrance, a slightly fresh floral fragrance and a slightly sweet fragrance in terms of olfactory aroma; in terms of sensory absorption, it has a rich cooling sensation, a clean aftertaste, a slightly minty fresh aroma, and a slightly sweet aftertaste in the mouth; thus, when applied to electronic cigarette atomization liquid, it has a significant effect in highlighting the cooling taste of electronic atomization.

[0027] Furthermore, the composite cooling agent includes the following components, measured by mass: 50 to 75 parts of N,2,3-trimethyl-2-isopropylbutyramide; 0.03 to 0.07 parts of caraway oil; 0.1 to 0.5 parts of carveol; 0.02 to 0.05 parts of white thyme oil; 0.1 to 1 parts of menthyl isovalerate; 0.05 to 0.1 parts of 1,4-cineole and 0.1 to 0.3 parts of cis-3,3,5-trimethylcyclohexanol. When WS-23 contacts the mouth and throat, it can quickly stimulate the sensory nerves and bring an immediate cool feeling. The cool feeling it provides is not only strong, but also smoother, without the strong spicy and wooden cool feeling that other non-menthol amide coolants may bring. In this application, WS-23 is used as the main coolant, so the mass fraction of WS-23 is relatively high. In addition, a small amount of carveol and caraway oil are used to supplement the cool feeling of the throat and the nasal cavity, and a small amount of white thyme oil, isovaleric acid menthyl, 1,4 eucalyptol and cis-3,3,5-trimethylcyclohexanol are used to provide a sweet feeling and reconcile the comprehensive experience of oral coolness, throat coolness and nasal coolness. At the same time, WS-23 can also make up for the defect of reduced comfort caused by other remaining substances to a certain extent, bringing an improvement in comfort. The use of the above mass fraction can better improve the comprehensive cooling effect.

[0028] Further, the composite cooling agent includes the following components by mass: 75 parts of N,2,3-trimethyl-2-isopropylbutyramide; 0.05 parts of caraway oil; 0.3 parts of carveol; 0.03 parts of white thyme oil; 0.5 parts of menthyl isovalerate; 0.07 parts of 1,4-cineole and 0.2 parts of cis-3,3,5-trimethylcyclohexanol. The above mass fractions can better improve the comprehensive cooling effect.

[0029] The present invention also provides an electronic cigarette atomizer liquid, comprising the above-mentioned composite cooling agent. The electronic cigarette atomizer liquid has all the technical solutions of the above-mentioned composite cooling agent, and thus has all the beneficial effects of the above-mentioned composite cooling agent, which will not be described in detail in the present invention.

[0030] Furthermore, in the electronic cigarette atomizer liquid, the mass proportion of the composite cooling agent is 3% to 8%. Specifically, the mass proportion of the composite cooling agent can be 3%, 5%, 8%, etc. When the mass proportion of the composite cooling agent is too high, the taste of the atomizer liquid will be too strong, affecting the user's comfort. When the mass proportion of the composite cooling agent is too low, the cooling effect will be too poor. Therefore, when the mass proportion of the composite cooling agent is within the above range, the cooling effect is more comprehensive, with a slight floral and fresh mint aroma, and the oral cavity is clean and comfortable, with a slight sweet aftertaste.

[0031] Furthermore, the electronic cigarette atomizer liquid also includes an atomizer, and the atomizer includes glycerin and propylene glycol. During the use of the electronic cigarette, glycerin is heated and atomized to produce an aerosol, and glycerin has a certain viscosity, which can increase the viscosity of the electronic cigarette liquid, thereby improving the taste of the atomizer liquid. This makes the electronic cigarette smoother during the smoking process and reduces the irritation to the throat. Propylene glycol is mainly used as a diluent in the electronic cigarette atomizer liquid. Propylene glycol can effectively dilute other components in the electronic cigarette atomizer liquid and reduce its concentration, thereby reducing irritation and harm to the human body.

[0032] Furthermore, the mass ratio of the propylene glycol to the glycerol is 1:(0.9-1.1). When the mass ratio of the propylene glycol to the glycerol is within the above range, the respective functions can be better exerted, making the taste of the electronic cigarette atomizer liquid smoother and more delicate.

[0033] The present invention also provides an electronic cigarette, including the electronic cigarette atomizing liquid. The electronic cigarette has all the technical solutions of the composite cooling agent, and thus has all the beneficial effects of the composite cooling agent, which will not be described in detail in the present invention.
