Description

Technical Field

[0001] The present application relates to the technical field of candle processing, and more specifically, to an environmentally friendly smokeless aromatherapy solid wax and a preparation process thereof. Background Art

[0002] Aromatherapy is a popular furniture product in modern home life and personal care. It is deeply loved by consumers for its unique fragrance, rich colors and diverse shapes. Aromatherapy not only adds a warm atmosphere to the indoor environment because of its soft light, but also emits a pleasant aroma when burning. It is widely used to create a relaxing atmosphere, relieve stress, improve sleep, provide a more comfortable environment, and significantly improve people's quality of life. However, with the continuous increase in market demand, consumers have increasingly stringent requirements for the quality of aromatherapy, especially in terms of fragrance persistence and consistency. The existing technology still has many shortcomings and needs to be improved.

[0003] With respect to the above-mentioned related technologies, the inventors found that most of the aromatherapy solid waxes on the market currently use paraffin, beeswax, etc. as the base material, and add fragrance ingredients such as plant essential oils to give them a specific fragrance. However, due to the combustion characteristics of traditional base materials, the speed at which aromatherapy solid wax releases aroma is difficult to control, resulting in the existing aromatherapy solid wax having a strong aroma at the beginning of combustion, but as time goes by, the aroma gradually weakens, and even disappears completely after burning for a period of time. Existing aromatherapy solid waxes also have the problem of uneven fragrance distribution, which may be caused by the heterogeneity of the internal structure of the candle or the uneven distribution of fragrance additives, resulting in differences in the intensity and type of fragrance experienced by users at different positions, affecting the overall sensory experience. Summary of the invention

[0004] In order to improve the fragrance persistence and uniformity of aromatherapy solid wax, the present application provides an environmentally friendly smokeless aromatherapy solid wax and a preparation process thereof.

[0005] In the first aspect, the present application provides an environmentally friendly smokeless aromatherapy solid wax, which adopts the following technical solution: An environmentally friendly smokeless aromatherapy solid wax, characterized in that, by weight, the raw materials include 70-80 parts of coconut wax, 35-45 parts of palm wax, 5-15 parts of beeswax, 3-7 parts of stabilizer, 1-5 parts of aromatherapy essential oil and 5-10 parts of aroma-fixing fiber; The raw materials of the aroma-fixing fiber include starch acetate, essence microspheres, porous starch and natural fiber.

[0006] By adopting the above technical scheme and using natural ingredients such as coconut wax, palm oil, beeswax, etc. as main raw materials, the emission of harmful substances in solid wax is effectively reduced, achieving an environmentally friendly and smoke-free effect, which is beneficial to indoor air quality and human health.

[0007] On the one hand, the present application introduces some aromatherapy essential oils into the solid wax matrix, and on the other hand, introduces solid aroma fibers containing essence microspheres into the solid wax matrix. The solid aroma fibers simultaneously achieve the adsorption of external aroma sources and the sustained release of internal aroma sources, forming a stable solid aroma network mechanism inside the solid wax.

[0008] The solid aroma fiber is evenly distributed in the solid wax matrix, ensuring the uniformity of aroma release. The solid aroma fiber can continuously absorb the aroma of the aroma oil in the solid wax matrix and slow down the rapid volatilization of the aroma oil from the solid wax. The fragrance microspheres are adsorbed by the solid aroma fiber, effectively locking the aroma components in the fragrance microspheres, significantly improving the stability and durability of the fragrance microspheres as an aroma source. During combustion, the aroma oil in the solid wax matrix will evaporate first, and then as the solid aroma fiber burns, the fragrance microspheres slowly release the internal aroma. The internal and external aroma sources of the solid aroma fiber synergistically release the aroma, which not only ensures the stability and durability of the aromatherapy solid wax, but also improves its aroma emission effect and overall quality.

[0009] In addition, the introduction of solid aroma fibers provides more burning surfaces, making the solid wax burn more evenly and fully, effectively reducing hot spots and incompletely burned areas, further reducing smoke generation, improving the aroma release efficiency, and being more environmentally friendly.

[0010] Optionally, the flavor microspheres are a structure in which the wall material includes the core material, and the raw materials include 2-4 parts by weight. Sodium alginate, 1.5-2.5 parts of modified starch, 8-12 parts of aromatherapy essential oils and 5-7 parts of palm oil.

[0011] Optionally, the preparation process of the flavor microspheres comprises the following steps: The aromatherapy essential oil and palm oil are uniformly mixed to obtain an oil phase; sodium alginate and modified starch are uniformly mixed, and then mixed with water at a solid-liquid ratio of 1: (15-20) to form a water phase; Adding the oil phase to the water phase, stirring and emulsifying, to obtain an oil-in-water emulsion; 3-5 wt % calcium chloride solution is added to the oil-in-water emulsion to solidify it, and the solution is allowed to stand, and the microcapsules are collected, filtered, and dried to obtain the microcapsules.

[0012] By adopting the above technical solution, the aromatherapy essential oil microencapsulation can effectively protect the aromatherapy essential oil, prevent it from volatilizing too quickly, and improve the persistence and sustained release effect of the aroma. Using modified starch and sodium alginate as wall materials can form an effective aroma-locking shell layer on the outside of the aromatherapy essential oil, while ensuring that the aroma microspheres can effectively release the internal aroma completely when burning, preventing the aroma inside the essence microspheres from being insufficiently released due to excessive blocking.

[0013] Optionally, the modified starch is selected from any one of hydroxyethyl starch and carboxymethyl starch.

[0014] By adopting the above technical solution, both hydroxyethyl starch and carboxymethyl starch have excellent water solubility and film-forming properties, which help to improve the stability and encapsulation effect of flavor microspheres.

[0015] Optionally, the preparation process of the aroma-fixing fiber comprises the following steps: According to weight parts, 10-15 parts of starch acetate and 3-7 parts of porous starch are mixed, and mixed with propanol at a solid-liquid ratio of 1:(7-9), and stirred to obtain a blend; Add 10-15 parts of natural fiber to the blend, stir ultrasonically to obtain spinning solution, then mature it, and obtain composite fiber by dry spinning; Mix 6-10 parts of flavor microspheres and 1.5-2.5 parts of adhesive, then mix with water at a material-liquid ratio of 1:(15-20) to make a finishing liquid, then pad and finish on the composite fiber 2-3 times, pre-bake at 65-75°C for 3-5 minutes, and then bake at 80-90°C for 3-5 minutes.

[0016] By adopting the above technical solution, starch acetate has good compatibility with porous starch and natural fibers, which helps to form uniform composite fibers. Both porous starch and natural fibers have excellent adsorption properties and can effectively adsorb and store aromatherapy essential oils. The pore structure of porous starch can achieve controlled release of the aroma of aromatherapy essential oils, providing a long-lasting and consistent fragrance experience.

[0017] The essence microspheres are adsorbed on the surface of the composite fiber by dipping and rolling, which can ensure that the essence microspheres can effectively release the aroma of the internal essential oil during combustion, thereby preventing the waste of aroma caused by insufficient aroma release due to tight blockage.

[0018] Optionally, the natural fibers are bamboo fibers and sugarcane fibers in a mass ratio of (2-5):(1-3).

[0019] By adopting the above technical solution, bamboo fiber and sugarcane fiber, as natural fibers, are both environmentally friendly and renewable. Bamboo fiber and sugarcane fiber produce less smoke when burned, which helps to reduce the smoke generated when solid wax burns.

[0020] The fibers of the two are interwoven into a composite carrier to form a porous structure. This porous structure helps oxygen to circulate inside the solid wax, reduces incomplete combustion and smoke caused by lack of oxygen, forms a better combustion surface, helps the solid wax to burn fully, reduces the release of volatile organic compounds in the candle, and further achieves smoke-free release.

[0021] Optionally, the stabilizer is microcrystalline wax.

[0022] By adopting the above technical scheme, the microcrystalline wax has a higher melting point and hardness, as well as good antioxidant properties, which can not only ensure the surface gloss of the aromatherapy solid wax, but also effectively prevent the solid wax from being oxidized and deteriorating during storage and use, and prevent the aroma of the aromatherapy essential oil in the solid wax from volatilizing, which helps to improve the combustion quality and combustion stability of the solid wax and reduce the generation of smoke.

[0023] Optionally, the aromatherapy essential oil is selected from any one of sandalwood essential oil, cedar essential oil, pine essential oil, agarwood essential oil, oak essential oil, camphor essential oil, patchouli essential oil, vetiver essential oil, and cypress essential oil.

[0024] By adopting the above technical scheme, sandalwood essential oil, cedar essential oil, pine essential oil, agarwood essential oil, oak essential oil, camphor essential oil, patchouli essential oil, vetiver essential oil and cypress essential oil are all wood essential oils. Wood fragrance has a lasting aroma, can create a tranquil and relaxing atmosphere, help improve sleep, help balance emotions, reduce anxiety and stress, and enhance people's mood.

[0025] In a second aspect, the present application provides a preparation process of an environmentally friendly smokeless aromatherapy solid wax, which adopts the following technical solution: A preparation process of environmentally friendly smokeless aromatherapy solid wax, comprising the following steps: According to the raw material ratio, coconut wax, palm wax, beeswax and stabilizer are melted and mixed evenly at 60-80°C to make mixed wax; aromatherapy essential oil and solid fragrance fiber are added to the mixed wax under heating conditions, and the mixture is stirred evenly to obtain wax liquid, and then wax is poured and cooled to obtain the product.

[0026] By adopting the above technical scheme, the volatilization of the aroma of the aromatherapy essential oil can be effectively prevented through the steps of melting and mixing the raw materials, adding the aromatherapy essential oil and the solid aroma fiber, stirring evenly, filling the wax and cooling. The process is simple and easy, environmentally friendly and sustainable, and can be produced on a large scale, so as to achieve efficient and stable preparation of environmentally friendly and smokeless aromatherapy solid wax.

[0027] In summary, this application has the following beneficial effects: 1. The coconut wax, palm wax, beeswax and other raw materials used in this application are all natural ingredients, easy to degrade, can effectively reduce the emission of harmful substances when solid wax is burned, achieve smokeless combustion effect, have little impact on the environment, and meet the environmental protection requirements of sustainable development.

[0028] 2. The present application introduces a solid aroma network structure formed by aromatherapy essential oils and solid aroma fibers into a solid wax matrix. The solid aroma fibers can effectively absorb the aroma of the aromatherapy essential oils in the solid wax matrix and slow down the volatilization of the aroma. At the same time, they can lock the aroma source in the essence microspheres inside the solid aroma fibers, effectively improving the aroma durability of the aromatherapy solid wax.

[0029] 3. The solid aroma fibers are evenly distributed in the solid wax matrix, providing more burning surfaces, making the solid wax burn more fully and evenly, ensuring the consistency and uniformity of aroma release.

[0030] 4. The flavor microspheres in this application use sodium alginate and modified starch as wall materials, forming a uniform and effective aroma-locking shell layer outside the core material. The flavor microspheres are combined with the aroma-fixing fibers by dipping and rolling, effectively preventing the waste of aroma caused by insufficient aroma release inside the flavor microspheres during combustion due to excessive blocking.

[0060] Performance testing Test Example 1: Combustion Performance Testing The combustion performance of the environmentally friendly smokeless aromatherapy solid wax obtained in Examples 1-14 and Comparative Examples 1-4 was tested, and each group of experiments was conducted 3 times, and the average value was taken as the final result and recorded in Table 6. The specific method is as follows: 1. Carbon black index (%): The carbon black index of the environmentally friendly smokeless aromatherapy solid wax of this application is tested in accordance with SN / T 3839-2014 "Standard for the determination of carbon black generated during the combustion process of imported and exported candles".

[0061] 2. Volume fraction of CO after combustion (‰): Place the environmentally friendly smokeless aromatherapy solid wax sample of the present application in a closed container filled with air and burn until the candle flame is extinguished, then use an infrared carbon monoxide analyzer to measure the carbon monoxide concentration after the candle burns in the closed container to obtain the volume fraction of CO. The smaller the volume fraction of CO, the less CO is produced by the combustion of the solid wax, and the more complete the combustion. Before the test, the volume fraction of oxygen in the closed container was 21%, and the volume fraction of carbon monoxide was 0.

[0062] Table 6 Test Example 2: Detection of fragrance holding performance The environmentally friendly smokeless aromatherapy solid wax obtained in Examples 1-14 and Comparative Examples 1-4 was placed in a room with a room temperature of 25° C. and a humidity of 30% and stored for 3 months, and the storage room was a room that could be exposed to natural sunlight.

[0063] After 3 months, take a sample from each group of scented candles, burn them separately in houses of the same area, and test them using "GB / T10220-2012 General Theory of Sensory Analysis Methodology" and "GB / T14454.2-2008 Flavor Aroma Evaluation Method", and place another sample in a cool and ventilated room.

[0064] 30 evaluators with evaluation ability were selected to evaluate the residual fragrance in the house after the aroma was burned. The fragrance was evaluated and scored 0.5h, 1h, 2h, 3h, 4h and 5h after burning, and the residual fragrance was tested (full score 10 points). Each sample was tested 3 times and the average value was taken as the final score result.

[0065] The evaluation results are based on the total score, and the standards are as follows: Excellent: total score ≥35; Good: total score ≥27 and <35; Normal: Total score ≥20 and <27; Failure: Total score < 20.

[0066] Table 7 in conclusion According to the performance test results of Table 6 and Table 7, it can be seen that the environmentally friendly smokeless aromatherapy solid wax of the present application has a low carbon black index, which means that the environmentally friendly smokeless aromatherapy solid wax of the present application after adding the solid aroma fiber still has excellent combustion characteristics, can be fully burned without leaving smoke, rarely produces harmful gases, has a low impact on human health, and meets the requirements of environmental protection and sustainable development. At the same time, the environmentally friendly smokeless aromatherapy solid wax of the present application has excellent fragrance holding ability and long-term storage stability, can slowly release a rich fragrance after long-term storage, and maintain the persistence and consistency of the fragrance.

[0067] According to the performance test results of Examples 1-11 and Examples 12-13, it can be seen that the composite fiber formed by mixing multiple fibers can form a better combustion surface compared to a single fiber as a solid fiber matrix, further promote the full combustion of solid wax, reduce the release of volatile organic compounds in candles, and further achieve smokeless release.

[0068] It can be seen from the performance test results of Examples 1-11 and Example 14 that, compared with dissolving the flavor microspheres in the solid fragrance fiber, adsorbing the flavor microspheres on the surface of the composite fiber by dipping and rolling can reasonably and effectively form a fixed network mechanism of aroma inside the solid wax, and can ensure that the flavor microspheres fully release the aroma of the essential oil inside when burning, avoiding the waste of aroma caused by insufficient aroma release due to tight blockage.

[0069] According to the performance test results of Examples 1-11 and Comparative Example 1, it can be seen that porous starch has excellent adsorption properties. When combined with natural fibers as the matrix of aroma-solid fibers, it can enhance the pore structure in the aroma-solid fibers, further achieve the sustained release of aroma, and enhance the aroma-solidifying ability of the aroma-solid fibers, thereby enhancing the aroma persistence and storage stability of the aromatherapy solid wax.

[0070] According to the performance test results of Examples 1-11 and Comparative Examples 2-4, it can be seen that the aromatherapy essential oil and the solid aroma fiber form a special solid aroma network mechanism inside the aromatherapy solid wax. On the one hand, the solid aroma fiber can effectively adsorb the aroma of the aromatherapy essential oil in the solid wax matrix, slow down the volatilization of the aroma, and improve the storage stability of the aromatherapy solid wax. On the other hand, it can effectively lock the aroma source in the essence microspheres inside the solid aroma fiber, effectively improving the aroma persistence and uniformity of the aroma of the aromatherapy solid wax.

[0071] This specific embodiment is merely an explanation of the present application and is not a limitation of the present application. After reading this specification, those skilled in the art may make modifications to the present embodiment without any creative contribution as needed. However, as long as it is within the scope of the claims of the present application, it shall be protected by the patent law.
