Description

Technical Field

[0001] The present application relates to the field of scented wax, and more specifically, to a scented wax that continuously releases negative ions and a preparation method thereof. Background Art

[0002] Scented candles are craft candles with special benefits. Their diverse appearances make them popular as a single item for enhancing quality of life and creating a relaxing atmosphere. Currently, most scented candles on the market are made from a simple blend of paraffin wax, vegetable wax, and essential oils. However, these traditional scented candles have numerous shortcomings. First, their functionality is relatively limited, mostly limited to simply distributing fragrance. This fails to meet current consumer demand for multifunctional aromatherapy products, such as air purification and air quality improvement, and falls short of meeting consumers' pursuit of improved quality of life and enhanced indoor environments. Second, regarding the use of essential oils, the essential oils in traditional scented candles evaporate rapidly upon heating, resulting in a short-lived fragrance. This results in much of the essential oil being lost to the air before being fully utilized. This not only wastes resources but also requires consumers to frequently replace the candles, increasing their cost of use. Furthermore, some additives used to impart special properties to scented candles, such as air purifiers, are difficult to evenly disperse throughout the candle, resulting in unstable performance and an inability to consistently and effectively perform their intended functions. This significantly reduces the effectiveness of scented candles in actual use, failing to meet consumer expectations. With the improvement of people's living standards and the growing demand for quality of life, the demand for aromatherapy wax products with richer functions and better performance is becoming more urgent. There is an urgent need to develop new aromatherapy wax products that are beneficial to human health and quality of life. Summary of the Invention

[0003] In order to prolong the duration of aromatherapy, stabilize the diffusion and improve the air quality, the present application provides a scented wax that continuously releases negative ions and a preparation method thereof.

[0004] In the first aspect, the present application provides a scented wax that continuously releases negative ions, using the following technical solution: Disclosed is a scented wax capable of continuously releasing negative ions. The raw materials of the scented wax include the following components in parts by weight: 40-50 parts of plant wax, 1-8 parts of an essential oil mixture, 1-2 parts of a stabilizer, 2-4 parts of a dispersant, and 5-10 parts of organosilicon-modified tourmaline. The essential oil mixture includes rose essential oil, lavender essential oil, and tea tree essential oil.

[0005] By adopting the above technical solution, organosilicon-modified tourmaline can release negative ions, actively combine with positively charged suspended particles in the air, improve air quality, and improve the dispersion stability of tourmaline through long-chain organosilicon modification, so that the contact area with air or moisture is wider, and the effect of improving air quality is better, thereby achieving the effects of purifying the air, regulating emotions, and alleviating diseases; organosilicon-modified tourmaline, on the one hand, enhances the mixed dispersion of tourmaline in aromatherapy wax, and the long branched chains formed on its surface are entangled with plant wax molecules, which is beneficial to prolonging the use time of plant wax, thereby achieving continuous and stable release of negative ions; on the other hand, the adsorption effect of organosilicon resin achieves a certain sustained-release effect on essential oils, improves the utilization rate of essential oils, reduces internal stress, and improves the stability and service life of aromatherapy wax, which is beneficial to the continuous release of negative ions and sustained release of essential oils.

[0006] The combination of rose essential oil, lavender essential oil and tea tree essential oil not only provides an aromatic scent but also has a stable and sustained release effect. Among them, the citronellol in rose essential oil and the (phenolic alcohol) in tea tree essential oil can also be antibacterial through different targets. The former destroys the lipid bilayer of the bacterial membrane, and the latter inhibits the activity of bacterial enzymes. Lavender essential oil can enhance the sedative effect and further improve the air quality. Therefore, the combination of the three has the effects of fresh fragrance, calming and soothing the nerves, stable and sustained release, anti-inflammatory and antibacterial. In addition, the ether bond in the molecular structure of eucalyptol in tea tree essential oil can have a dipole electrostatic interaction with the siloxane group in silicone, so the two have good compatibility, enhance the adsorption and sustained release effect of silicone-modified tourmaline on essential oils, and thus significantly improve the stability and dispersion and sustained release of aromatherapy wax. It has the dual functions of air purification and fragrance, can improve the utilization rate of essential oils, save costs, prolong the duration of fragrance, and meet consumers' demand for multifunctional home products.

[0007] In a specific embodiment, the preparation method of the organosilicon-modified tourmaline includes adding tourmaline to an ethanol aqueous solution at 60-70° C. for reaction for 2-3 hours, then adding γ-glycidyloxypropyltrimethoxysilane, stirring and mixing, and then adding a toluene solution containing an epoxy silicone resin, stirring for 18-24 hours to obtain the organosilicon-modified tourmaline.

[0008] The mass ratio of the tourmaline to the epoxy silicone resin is 1:(0.6-1.2).

[0009] By adopting the above technical solution, tourmaline is mixed and modified with epoxy silicone resin, which can further optimize the stable dispersion of modified tourmaline in aromatherapy wax, so that the modified tourmaline can better entangle with the plant wax molecular chain in the plant wax and continuously release negative ions. It can also further enhance the adsorption and sustained release effect of silicone resin on essential oils, improve the utilization rate of essential oils, save costs and further help to increase the use time of wax. The alkoxy groups of γ-glycidoxypropyltrimethoxysilane react with the hydroxyl groups on the tourmaline surface to graft silane molecular chains onto the tourmaline surface, transforming the surface from hydrophilic to lipophilic, enhancing compatibility with plant waxes. This improves the dispersion of tourmaline in the plant wax, prevents tourmaline agglomeration, and enables the aromatherapy wax to steadily and continuously release negative ions. Simultaneously, the adsorption effect of the silicone resin slows the volatilization rate of the essential oil, ensuring a longer-lasting aroma release and extending the negative ion release period. Furthermore, the active hydroxyl and amino groups on the silane molecular chains chemically bond with the silicon-oxygen bonds in the silicone resin to form a three-dimensional network structure, forming a silicone coating on the tourmaline surface. This three-dimensional network of silicone resin not only absorbs essential oil molecules for sustained release, but also allows the long branched chains on the tourmaline surface to entangle with plant wax molecules, extending the wax's usable life and ensuring the sustained release of negative ions. This allows the essential oil molecules to diffuse slowly through the resin network, preventing rapid volatilization. Therefore, if the epoxy silicone resin is too little, the tourmaline may not be completely coated, which is not conducive to a stable three-dimensional network structure, and the sustained and stable release performance is reduced.

[0010] In a specific embodiment, the mass ratio of the rose essential oil, lavender essential oil, and tea tree essential oil is 2:0.5:(1-1.2).

[0011] By adopting the above technical solution, the combination of rose essential oil, lavender essential oil, and tea tree essential oil in the proportions of this application not only provides a pleasant and calming aroma but also has bactericidal and antibacterial effects. Rose essential oil and tea tree essential oil can have different antibacterial effects. The combination of the three has the effect of stabilizing and slow-releasing the aroma, preventing the rapid volatilization of a single essential oil, extending the duration of the aroma, and improving the utilization rate of the essential oil. A low tea tree essential oil content reduces the adsorption and slow-release effect of the silicone resin on the essential oil, which may affect the stable release of the fragrance.

[0012] In a specific embodiment, the plant wax includes one or more of soybean wax, rapeseed wax, and palm wax.

[0013] Preferably, the plant wax is maleic anhydride-modified soybean wax and castor oil-modified palm wax in a mass ratio of (1.5-3):1.

[0014] By adopting the above technical solution, soybean wax is modified with maleic anhydride, and carboxyl groups are introduced into the soybean wax molecular chain. On the one hand, these groups can react with the hydroxyl groups in the silane molecules on the surface of the modified tourmaline to form a stronger chemical bond. On the other hand, these groups can react with the active hydroxyl groups on the castor oil-modified palm wax to enhance stability. Castor oil-modified palm wax contains a large number of hydroxyl groups and unsaturated double bonds, which also form hydrogen bonds with the silane molecules on the surface of the modified tourmaline, thereby improving compatibility with essential oils, silicone-modified tourmaline, etc., and enhancing the dispersibility of the modified tourmaline in the plant wax. This in turn promotes cross-linking and improves the overall stability of the aromatherapy, thereby greatly extending the burning life and burning stability of the aromatherapy wax, and improving the stability and sustained release effect of the essential oil. Too low a soybean wax content may affect the thermal stability of the plant wax, which may cause the aromatherapy to deform due to heat, affecting the negative ion and essential oil sustained release effect.

[0015] The stabilizer is glyceryl stearate, and the dispersant is polyoxyethylene sorbitan fatty acid ester.

[0016] In a second aspect, the present application provides a method for preparing scented wax that continuously releases negative ions, using the following technical solution: A method for preparing scented wax that continuously releases negative ions comprises the following steps: Mix the silicone-modified tourmaline and essential oil mixture in proportion, stir at room temperature, then add stabilizer and dispersant and continue stirring; finally add to the plant wax preheated to 40-45°C, stir for 15-25 minutes, then heat to 45-50°C, pour into a shaping mold, cool and solidify to room temperature, and you will get the aromatherapy wax that continuously releases negative ions.

[0017] The mixing and stirring is carried out at a rotation speed of 300-500 r / min for 1-1.5 hours.

[0018] In summary, this application includes at least one of the following beneficial technical effects: 1. Silicone-modified tourmaline enhances the mixing and dispersibility of tourmaline in scented wax, achieving a sustained and stable release of negative ions. The adsorption of silicone resin achieves a certain sustained-release effect on essential oils, reduces internal stress, and improves the stability and service life of scented wax, thereby facilitating the sustained release of negative ions and the sustained release of essential oils. The combination of rose, lavender, and tea tree essential oils not only provides a fragrant scent but also has bactericidal and antibacterial effects. The use of modified mixed plant wax as a wax matrix allows for better integration with the sustained-release essential oils and silicone-modified tourmaline, maintaining good thermal stability and enhancing the dispersion properties of the essential oils and modified tourmaline. This extends the aroma release time and the stable release of aroma negative ions, thereby improving air quality and extending the service life of the scented wax. The stability and sustained-release properties of the scented wax are significantly improved, providing the dual functions of air purification and fragrance. This can improve the utilization rate of essential oils, save costs, and prolong the duration of fragrance, meeting consumer demand for multifunctional home products.

[0019] 2. The combination of rose, lavender, and tea tree oils in the specified proportions not only provides a pleasant and calming aroma but also has antibacterial and antimicrobial properties. Rose and tea tree oils can act as antibacterial agents through different means, and their combined use creates a sustained-release effect, preventing the rapid volatilization of a single essential oil, extending the duration of the fragrance, and improving the utilization rate of the essential oils. However, a low tea tree oil content reduces the adsorption and sustained-release properties of the silicone resin, potentially affecting the stable release of the fragrance. DETAILED DESCRIPTION

[0048] Performance testing For the scented wax that continuously releases negative ions prepared in the embodiments and comparative examples, a: sensory test was performed: a sample was taken from each of the scented candles that continuously release negative ions prepared in the embodiments and comparative examples of the present application after storage for three months, and burned separately in houses of the same area. The test was carried out using "GBT102202012 General Theory of Sensory Analysis Methodology" and "GBT14454.22008 Fragrance Aroma Evaluation Method". 20 evaluators with evaluation ability were selected to evaluate the fragrance residue in the house after the aroma was burned. The fragrance at 0.5h and 5h after burning, and the comfort of breathing before and after 0.5h and 5h purification were evaluated and scored. The fragrance residue and freshness (full score 10 points) were tested. Each sample was tested 3 times, and the average value was taken as the final result. The evaluation result was formulated according to the total score. When the total score was greater than or equal to 15, the evaluation result was excellent, when the total score was greater than or equal to 10, the evaluation result was good, and when the total score was less than 10, the evaluation result was unqualified. b: Scented candle burning time test: The industry standard "QB / T 2119-2007 Ordinary Candles" is used for testing. A sample weighing 25g, 60mm in height and 20mm in diameter is placed at 25°C. The time it takes for the sample to burn out is measured. Repeat three times and take the average.

[0049] c: Thermal stability test: The scented waxes with sustained negative ion release of the examples and the control examples were placed in a constant temperature box at 35±1°C for 24 hours, and the deformation and appearance were observed; Combined with the above table, the aromatherapy waxes of Examples 1-4 and Comparative Examples 1-6 that continuously release negative ions are compared. The results show that, whether from the perspective of sensory fragrance stability experience, air purification experience, continuous burning life and shape stability, Example 1 has better effects than the aromatherapy wax of the comparative example that continuously releases negative ions. The analysis shows that the combined use of rose essential oil, lavender essential oil and tea tree essential oil not only provides a fragrant smell but also has the effect of sterilization and antibacterial purification of the air. The interaction between tea tree essential oil and silicone enhances the adsorption and sustained release effect of silicone-modified tourmaline on essential oils, thereby significantly improving the stability and dispersion and sustained release of the aromatherapy wax. It has the dual functions of air purification and fragrance, can improve the utilization rate of essential oils, prolong the duration of fragrance, and meet consumers' demand for multifunctional household products.

[0050] By comparing Example 1 with Examples 5-11, it can be seen that by modifying soy wax and palm wax separately and interacting with each other, the aromatherapy wax not only has more stable mechanical stability, but also improves the interaction with tourmaline and essential oils to thereby improve compatibility, enhances the stable release of essential oil aroma and negative ions, and extends the burning service life.

[0051] By comparing Example 1 with Examples 12-13 and Comparative Example 7, it can be seen that tourmaline is mixed and modified with epoxy silicone resin to form a silicone-coated three-dimensional sustained-release structure as the structural basis for stable release. The modified tourmaline is better entangled with the plant wax molecular chains in the plant wax, thereby extending the use time, and enhancing the adsorption and sustained-release effect of the silicone resin on the essential oil, thereby improving the utilization rate of the essential oil, slowing down the volatilization rate of the essential oil, making the aroma release more lasting, and extending the negative ion release cycle.

[0052] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
