Description

Technical Field

[0001] The invention belongs to the technical field of aromatherapy products, and particularly relates to an aromatherapy pendant and applications thereof. Background Art

[0002] Nicotine, an alkaloid primarily found in tobacco, is the primary cause of cigarette addiction. It enters the body through smoking, chewing tobacco, and snuff, stimulating the central nervous system and producing a brief sense of euphoria and pleasure. However, long-term use can lead to dependence, a condition known as nicotine addiction. Nicotine can also increase heart rate and blood pressure, increasing the risk of cardiovascular disease. For smokers, reducing nicotine use or switching to nicotine-free alternatives are key ways to mitigate these risks.

[0003] However, although nicotine replacement products provided by existing technologies, such as e-cigarettes, can indeed reduce smokers' intake of harmful substances, their nicotine content is still relatively high, so long-term use may still lead to nicotine dependence. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the purpose of the present invention is to provide an aromatherapy pendant and its application, which can achieve a small amount of slow release of nicotine, and can provide a new and better consumer choice for people who want to quit smoking and patients who need nicotine for medicinal use.

[0098] Test Example 1 Sensory Evaluation

[0099] The evaluation method involved setting up 10 sensory evaluators, each with an evaluation form, and using a blind evaluation scoring method. Each evaluator experienced the aromatherapy pendants of Examples 1-9 and Comparative Examples 1-3 and scored them. The highest and lowest scores were removed, and the average was taken. The specific definitions of the sensory quality evaluation indicators are shown in Table 1, the scoring criteria are shown in Table 2, and the scoring results are shown in Table 3 (the average of each group was taken, rounded to one decimal place).

[0100] Table 1

[0101]

[0102] Table 2

[0103]

[0104] Table 3

[0105]

[0106]

[0107] As can be seen from Table 1, the aromatherapy pendants obtained in Examples 1-3 of the present invention can provide sensory evaluations with a sense of nicotine satisfaction and a harmonious and pleasant aroma.

[0108] It can be seen from Examples 4-5 that when the wall material is not a combination of chitosan and sodium alginate, the nicotine release effect will be affected, thereby affecting the experience of the final pendant.

[0109] As can be seen from Example 6, when pure nicotine is used instead of the nicotine microcapsules of the present invention, although the nicotine satisfaction is higher, the overall fragrance harmony of the pendant is poor.

[0110] As can be seen from Examples 7-9, when the polyol is the combination of propylene glycol, pentaerythritol and sorbitol selected in the present invention, the aroma of essential oil and nicotine can be better coordinated, so that the aroma of the final aromatherapy pendant is non-irritating and more harmonious.

[0111] It can be seen from Comparative Examples 2 and 3 that the choice of plant essential oil also affects the aroma harmony of the aromatherapy, and lavender essential oil and peppermint essential oil have a synergistic effect in coordinating the taste of nicotine.

[0112] Test Example 2 Evaluation of sustained-release effect

[0113] The aroma diffusers of Examples 1-6 and Comparative Example 1 were placed in an indoor area with good air flow. The diffusers were smelled after 10, 30, and 60 days to determine if they still had nicotine aroma. The evaluation criteria were: normal aroma, weak aroma, and no aroma. The results are shown in Table 4.

[0114] Table 4

[0115] Serial number 15 days 30 days 60 days Example 1 Normal fragrance Normal fragrance Light fragrance Example 2 Normal fragrance Normal fragrance Light fragrance Example 3 Normal fragrance Normal fragrance Light fragrance Example 4 Normal fragrance Light fragrance Light fragrance Example 5 Normal fragrance Light fragrance Light fragrance Example 6 Light fragrance Unscented Unscented Comparative Example 1 Unscented Unscented Unscented

[0116] As shown in Table 4, the aromatherapy pendant of the present invention has a long-lasting sustained-release effect, and the choice of wall material of the nicotine microcapsules has a great influence on the sustained-release effect. When pure nicotine is used instead of nicotine microcapsules, the sustained-release effect of the perfume is significantly reduced.

[0117] The applicant declares that the present invention uses the above-described embodiment to illustrate an aromatherapy pendant and its application, but the present invention is not limited to the above-described detailed method, that is, it does not mean that the present invention must rely on the above-described detailed method for implementation. Those skilled in the art should understand that any improvements to the present invention, equivalent substitutions for various raw materials in the present invention, addition of auxiliary ingredients, and selection of specific methods, etc., are all within the scope of protection and disclosure of the present invention.
