[0031] In an alternative example, in the cooling agent composition, the parts by mass of menthol can be, but are not limited to, 2 parts, 3 parts, 4 parts, 5 parts, 6 parts, 7 parts, 8 parts, or the range formed by any two of these values. Optionally, in the cooling agent composition, the parts by mass of menthol are 3 parts to 6 parts.

[0032] In some embodiments, by parts by mass, the cooling agent composition consists of 30 parts to 45 parts of WS-23, 2 parts to 8 parts of WS-27, and 2 parts to 8 parts of menthol.

[0033] In some embodiments, in the cooling agent composition, the mass ratio of WS-23 to WS-27 is (7 to 12):1. For example, the mass ratio of WS-23 to WS-27 can be, but is not limited to, 7:1, 7.5:1, 8:1, 8.5:1, 9:1, 9.5:1, 10:1, 10.5:1, 11:1, 11.5:1, 12:1, or the range formed by any two of these values.

[0034] In some embodiments, in the cooling agent composition, the mass ratio of WS-23 to menthol is (7 to 12):1. For example, the mass ratio of WS-23 to menthol can be, but is not limited to, 7:1, 7.5:1, 8:1, 8.5:1, 9:1, 9.5:1, 10:1, 10.5:1, 11:1, 11.5:1, 12:1, or the range formed by any two of these values.

[0035] In some embodiments, by parts by mass, the cooling agent composition includes: 35 parts to 42 parts of WS-23, 3 parts to 6 parts of WS-27, and 3 parts to 6 parts of menthol.

[0037] Currently, the components of current food-grade cooling agents that can be atomized in an electronic atomization device to give a cooling sensation to the human senses are limited, such as: WS-23, WS-3 (N-ethyl-p-menthane-3-carboxamide), WS-5 (N-(ethoxycarbonylmethyl)-p-alkane-3-carboxamide), WS-27 and menthol, etc. The inventors have found through research that the oral cooling sensation of WS-23 is weak; the cooling sensation intensity of WS-27 is slightly weaker than that of WS-23, but it has an unpleasant smell during atomization and suction; the nasal and oral cooling sensations of WS-3 and WS-5 are not obvious; menthol has its special mint aroma and bitter taste. Through a large amount of creative work, the inventors compound WS-23, WS-27 and menthol in a certain proportion, so that the cooling agent composition is suitable for atomization, and improves the richness and comfort of the cooling sensation parts, thereby enhancing the cooling experience of the user's electronic cigarette.

[0038] Among them, the richness of the cooling sensation means that the more the number of cooling sensation parts, the richer it is, that is, the "rich" cooling sensation can be perceived not only in one or a certain part, but in multiple parts. The comfort of the cooling sensation means that the intensity is moderate and the intensity is coordinated, that is, the intensities in different parts are balanced and there is no phenomenon of excessive cooling in individual parts; there is no negative unpleasant smell or other flavors. By adjusting menthol within an appropriate concentration range, the perceived smell is pleasant.

[0119]

[0120] Load the e-liquids prepared in the above examples and comparative examples into the same atomizer and provide them to 30 professional sensory evaluators for blind sampling evaluation. According to the sensory indicators and grade standards, determine the sensory scores of the samples. Among them, the sensory indicators include the degree of coolness in the oral cavity, larynx (also called the laryngeal ventricle), lower larynx, and nasal cavity, as well as abnormal odors. The professional sensory evaluators score according to the intensity of the coolness they feel. 0 points means no coolness, and 5 points means extremely strong coolness. The specific coolness scoring indicators are shown in Table 2 below. For abnormal odors, 0 points means no abnormal odor, and 5 points means extremely strong abnormal odor. The specific abnormal odor scoring indicators are shown in Table 3 below.

[0121] Table 2 Scoring criteria for coolness intensity

[0122]

[0123] Table 3 Scoring criteria for the intensity of abnormal odors

[0124]

[0125] Thirty professional evaluators first study the evaluation results of various standard samples and use them as a reference to blindly sample the e-liquids of the examples and comparative examples. According to the sensory indicators and the intensity of coolness, determine the scores of each sensory indicator of the samples. Take the average score of the 30 professional sensory evaluators as the score of each sensory indicator. The specific results are shown in Table 4. In Table 4, the coolness richness is the average of the degrees of coolness in the oral cavity, larynx, lower larynx, and nasal cavity. Among them, when the coolness score of the lower larynx is greater than 1, the experience is not good. The effect is better when the score of the coolness richness is around 3. Being much higher than 3 will produce an overly cool effect, and being much lower than 3 will produce a less cool effect.

[0128] As can be seen from Table 4 above, compounding WS-23 with WS-27 and menthol to prepare a cooling agent and using it in the e-liquid can increase the intensity of coolness in the oral cavity and larynx and increase the richness of the coolness during the puffing of the e-cigarette.

[0129] As can be seen from the e-liquids of Example 1, Example 4 and Example 5, the coolness scores in the oral cavity, larynx and nasal cavity parts of their senses are not abnormally high or low, and the coolness comfort is better than that of the e-liquids of any comparative example.

[0130] As can be seen from the comparison between Comparative Example 1 to Comparative Example 2 and Example 2, in the cool flavor agent composition, the dosages of WS-23, WS-27 and menthol are not within the range, the sensory effect evaluation is not good, abnormal odors are prominent, and the coolness in the lower larynx is weak. As can be seen from the comparison between Comparative Example 3 and Example 2, the nasal cavity coolness of the cool flavor agent composition of Comparative Example 3 is significantly insufficient, and the coolness richness is poor.

[0131] As can be seen from the comparison between Example 3 and Comparative Example 4 to Comparative Example 6, in the flavor agent composition, the dosages of WS-23, WS-27 and menthol are not within the range, the sensory effect evaluation is not good, the coolness richness of the cool flavor agent composition of Comparative Example 4 is insufficient, the larynx coolness degree of the cool flavor agent composition of Comparative Example 5 is not enough, and the nasal cavity coolness degree of the cool flavor agent composition of Comparative Example 6 is too high.
