Description

Technical Field

[0001] The present application relates to the field of scented wax, and in particular to a soybean wax scented candle capable of stably diffusing fragrance and a preparation method thereof. Background Art

[0002] The main raw material for candle manufacturing is paraffin extracted from petroleum. Different additives such as flavors, pigments, antioxidants, etc. are added to the wax to give candles different smell characteristics or functions to meet different uses. Aromatherapy candles are craft candles with special effects. They have rich and varied shapes and beautiful colors. The natural plant essential oils they contain can emit a pleasant fragrance. They have the effects of beauty and health care, soothing nerves, purifying the air, and eliminating odors. They can also be used as a single product to improve the quality of life and create a comfortable atmosphere, and are loved by the public. Traditional aromatherapy wax has a single shape, is fragile, and has poor toughness. It does not burn fully during the ignition process and is prone to smoke when ignited, causing environmental pollution and human harm.

[0003] Soy wax is a plant wax made from soybeans. It is smokeless and odorless when burned, and has a relatively low melting point and a relatively long burning time. It can blend well with essences and slowly release fragrance when burning, making it an ideal material for making scented candles. However, the aromatherapy essential oils in scented candles are highly volatile. When blended with soy wax, soy wax melts at a lower temperature, which makes it easy to quickly release the aroma and form a larger melting pool. However, the aroma release is uneven and unstable, with low continuous stability and poor shape retention, which causes the essence to quickly dissipate and volatilize, resulting in a loss of the aromatherapy candle's healing effects of decompressing and soothing the body and mind. Summary of the invention

[0004] In order to improve the shape stability and aroma release stability of soybean wax aromatherapy at higher temperatures and maintain a unique aroma atmosphere for a longer burning period, the present application provides a soybean wax aromatherapy candle that can stably diffuse aroma and a preparation method thereof.

[0005] In a first aspect, the present application provides a soy wax scented candle that can stably diffuse aroma, using the following technical solution: A soybean wax scented candle capable of stably diffusing fragrance comprises a wax material and a candle wick; the raw materials of the wax material comprise the following components in parts by mass: 70-85 parts of mixed soybean wax, 2-5 parts of a stabilizer, 11-15 parts of plant essential oils, 15-25 parts of a sustained-release oil-controlling agent, and 0.2-0.4 parts of an ultraviolet absorber, wherein the sustained-release oil-controlling agent comprises fumed silica, cyclodextrin, and orange peel extract.

[0006] By adopting the above technical scheme, the soy wax is mixed to achieve better fusion with the slow-release oil control agent, and as a wax matrix, the aromatherapy will not separate and deform when not burning, and the soy wax aromatherapy candle is also fragrant when not burning. The stabilizer and the aromatherapy matrix are combined so that the unburned part of the aromatherapy will not deform or soften even when it is burned again, which has a good effect of controlled diffusion of fragrance. The addition of stabilizers and the like makes the plant essential oil stably combined with the mixed soy wax without emitting, reducing volatilization; adding ultraviolet absorbers further prolongs the service life of the aromatherapy, and a high-scent plant candle can be obtained with good combustion performance, stable color, fine paste, dense crystals, no precipitation of essential oil, and non-greasy packaging. The stable addition of plant essential oil content meets the market demand for high-concentration fragrance.

[0007] Due to the large specific surface area of ​​fumed silica and a large number of microporous and mesoporous pores, plant essential oils can enter the gaps, effectively delaying the release of active ingredients in the essential oils and preventing oil seepage. On the other hand, fumed silica has a large dispersibility and high mechanical strength, which greatly improves the stability of the wax material. By adding cyclodextrin, the internal groups of the cyclodextrin cavity can make the intermolecular force between cyclodextrin and silica, so that the cyclodextrin enters part of the silica, filling the excess pores of fumed silica on the one hand to prevent the mixed soybean wax and plant essential oils from being tightly filled and affecting the fragrant volatilization of the essential oils. On the other hand, the surface groups of cyclodextrin can hydrogen bond with plant essential oils, mixed soybean wax and other parts, which helps to release the aroma evenly, improve the continuous stability of soybean wax aromatherapy, and maintain a stable shape. Adding orange peel extract can increase the antioxidant property of the soybean wax aromatherapy matrix, so that the candles can maintain bright colors, no discoloration, and long-lasting maintenance, and the stability of the candles is improved.

[0008] In a specific embodiment, the mass ratio of the fumed silica, cyclodextrin and orange peel extract is (5-8):(1-3):1.

[0009] By adopting the above technical scheme and the mixing ratio range of fumed silica, cyclodextrin and orange peel extract in the present application, the soybean wax aromatherapy has the effects of stable combustion, good shape retention, and continuous emission of rich fragrance. If the content of fumed silica is too little, the shape retention and stability of the aromatherapy candle will be insufficient, which may cause the candle to soften too quickly, which is not conducive to the controllable and continuous emission of fragrance. If the content of cyclodextrin is too low, the compatibility of fumed silica will be poor, which will reduce the adsorption of essential oils and soybean wax, causing the wax base to become turbid, precipitated, and uneven in color, thereby reducing the combustion stability.

[0010] In a specific embodiment, the mixed soybean wax includes 52-degree vegetable soybean wax and 48-degree vegetable soybean wax in a mass ratio of (5-8):1.

[0011] By adopting the above technical scheme, by adding two kinds of plant soy waxes with different melting points and plasticity, the fragrance sustained release effect is better, and the continuous fumigation environment continues to have a rich fragrance. Adding a small amount of 48-degree plant soy wax to the 52-degree plant soy wax with better toughness and plasticity can release the fragrance more quickly, and it is easier to blend additives such as stabilizers, and then combined with 52-degree plant soy wax to achieve fragrance sustained release, ensuring the stable and uniform burning texture of the soy wax.

[0012] In a specific embodiment, the stabilizer includes polyanionic cellulose and nano zinc oxide aqueous dispersion.

[0013] The mass ratio of the polyanionic cellulose and the nano zinc oxide aqueous dispersion is (2-5):1.

[0014] Polyanionic cellulose with good stability and good compatibility can be further dissolved in the soybean wax and essential oil system with the sustained-release oil control agent to thicken the aromatherapy, increase adhesion, and thicken the aromatherapy wax base. Then, nano zinc oxide aqueous dispersion is added to maintain the dispersibility of fumed silica, further strengthening the wax base of the soybean wax aromatherapy, ensuring the toughness and high volatility of the soybean wax aromatherapy, and helping to release the aroma evenly, ensure continuous and stable combustion, and maintain a good shape.

[0015] In a specific embodiment, the plant essential oil includes any one or more of lavender oil, rosemary oil, lemon essential oil, orange essential oil, and chamomile essential oil.

[0016] Plant essential oils are easier to blend with soy wax, so that as the soy wax burns, the special aroma of the essential oils is released, increasing the aromatherapy atmosphere.

[0017] The ultraviolet absorber includes resorcinol monobenzoate.

[0018] In a second aspect, the present application provides a method for preparing a soy wax scented candle that can stably diffuse aroma, using the following technical solution: A method for preparing a soybean wax scented candle capable of stably diffusing fragrance comprises the following steps: The sustained-release oil control agent and the plant essential oil are mixed and stirred evenly at room temperature, and then the stabilizer and the ultraviolet absorber are added and stirred continuously; finally, the mixture is added into the mixed soybean wax preheated to 40-45°C, stirred for 2-10 minutes, and then heated to 55-60°C to obtain the wax material; Pour the wax into a shaping mold, insert the candle wick longitudinally into the wax while it is still hot, and finally cool and solidify to room temperature to obtain an oil-control soy wax scented candle.

[0019] The mixing and stirring is carried out at a rotation speed of 80-120 r / min and the stirring time is 5-10 min.

[0020] In summary, the present application includes at least one of the following beneficial technical effects: 1. By mixing soy wax, the fusion with the slow-release oil control agent is better. As the wax matrix, the aromatherapy will not separate and deform when it is not burning. The combination of plant essential oils makes the soy wax scented candles have fragrance when they are not burning. The combination of stabilizer and aromatherapy matrix makes the unburned part of the aromatherapy not deformed and softened even when it is burned again, which has a good effect of controlled diffusion of fragrance. The addition of stabilizers makes the plant essential oil stably combined with the mixed soy wax without emitting, reducing volatilization; adding ultraviolet absorbers further extends the service life of the aromatherapy, and a high-scent plant candle can be obtained with good combustion performance, stable color, fine paste, dense crystals, no precipitation of essential oil, and non-greasy packaging. The stable addition of plant essential oil content meets the market demand for high-concentration fragrance.

[0021] 2. Through the matching ratio range of fumed silica, cyclodextrin and orange peel extract in this application, the soybean wax aromatherapy has the effects of stable combustion, good shape retention, and continuous emission of rich fragrance. If there is too little fumed silica, the shape retention and stability of the aromatherapy candle will be insufficient, which may cause the candle to soften too quickly, which is not conducive to the controllable and continuous emission of fragrance. If the cyclodextrin content is too low, the fumed silica will have poor compatibility, reduce the adsorption of essential oils and soybean wax, make the wax base turbid, precipitate, uneven color, and reduce combustion stability.

[0038] Performance Testing For the soy wax scented candles with stable aroma diffusion prepared in the embodiments and comparative examples, a: sensory test was performed: the soy wax scented candles prepared in the embodiments and comparative examples of the present application were placed at 30°C and under direct sunlight for 36 hours, and 20 people with normal sense of smell were randomly selected to compare the appearance of the scented candles prepared in each embodiment and comparative example when not ignited, and the candles were evaluated by sense of smell within 10 minutes after ignition, and the evaluation results recognized by the majority were taken; the odor evaluation grades can be divided into: stable and strong fragrance, stable and soft fragrance, stable and weak fragrance, strong fragrance, soft fragrance, and weak fragrance; the oil droplet seepage standard is divided into: oil seepage of ≤5mg per 100g wax material is oil droplet micro-seepage, oil seepage of ≤10mg per 100g wax material is oil droplet small seepage, and oil seepage of >10mg per 100g wax material is oil seepage; b: Stability test: The temperature is maintained at 40°C for 60 days to observe whether the properties are stable, and the temperature is maintained at -20°C for 60 days to observe whether the properties are stable. Then the above-mentioned temperature maintenance operation is cycled three times at -20°C and 40°C, and then the properties are observed to be stable. In the stability test results, the texture is uniform in all three temperature change cycles, without mold, discoloration, cracking, and obvious oil leakage (excluding the appearance of small oil drops), which means that the properties are stable and have good stability; otherwise, it does not have good stability; and the ambient temperature is started from 35°C, and the scented candle products with intact outer packaging prepared in each embodiment and preparation example are gradually heated up, and the outer packaging is an ordinary transparent plastic box. The test results are shown in the following table: Sensory Oil seepage stability Example 1 Stable and rich aroma No oil seepage Uniform texture, no cracking, stable shape Example 2 Stable and soft fragrance No oil seepage Uniform texture, no cracking, stable shape Example 3 Stable and rich aroma Oil droplet micro-seepage Uniform texture, no cracking, slight deformation Example 4 Stable and rich aroma Oil droplet micro-seepage Uniform texture, no cracking, stable shape Example 5 Stable and rich aroma No oil seepage Uniform texture, no cracking, stable shape Example 6 Stable and rich aroma A small amount of oil droplets seep out Uniform texture, no cracking, stable shape Example 7 Stable and rich aroma Oil droplet micro-seepage Uniform texture, no cracking, stable shape Comparative Example 1 Rich aroma Oil droplet micro-seepage Uneven texture, slight cracking, stable shape Comparative Example 2 Soft fragrance A small amount of oil droplets seep out Uneven texture, slight cracking, stable shape Comparative Example 3 Rich aroma A small amount of oil droplets seep out Uneven texture, slight cracking, deformation, softening Comparative Example 4 Soft fragrance A small amount of oil droplets seep out Uneven texture, cracking, deformation Comparative Example 5 Soft fragrance Oil Leakage Uneven texture, deformation, softening Comparative Example 6 Weak fragrance Oil Leakage Uniform texture, deformation, softening Combined with the above table, the soy wax scented candles with stable aroma diffusion of Example 1 and Example 3 and Comparative Examples 1-6 are compared. The results show that no matter from the perspective of sensory aroma stability experience, oil penetration, and shape stability, Example 1 is better than the soy wax scented candles with stable aroma diffusion made by the comparative examples. It is analyzed that, through the matching ratio range of fumed silica, cyclodextrin and orange peel extract in the present application, the soy wax aroma has the effects of stable combustion, good shape retention, and continuous emission of rich fragrance, which helps to release the aroma evenly, improve the continuous stability of the soy wax aroma, and maintain shape stability; too little fumed silica will result in insufficient shape retention and stability of the scented candle, which may cause the candle to soften too quickly, which is not conducive to the controllable and continuous emission of fragrance; too low cyclodextrin content will lead to poor compatibility of fumed silica, reduce the adsorption of essential oils and soy wax, make the wax base turbid, precipitate, uneven color, and reduce combustion stability.

[0039] By comparing Example 1 with Examples 4-6, it can be seen that from the perspective of the stable sensory fragrance experience, oil penetration, and shape stability, Example 1 is better than the comparative example in terms of the effect of the soy wax scented candle that can stably diffuse the aroma. The analysis shows that the polyanionic cellulose with good stability and good compatibility can be further dissolved in the soy wax and essential oil system with the sustained-release oil control agent, so that the aroma is thickened, the adhesion is increased, the aroma wax base is thickened, and then the nano zinc oxide aqueous dispersion is added to maintain the dispersibility of the fumed silica, further strengthening the wax base of the soy wax aroma, ensuring the toughness and high volatility of the soy wax aroma, and contributing to the uniform release of the aroma, continuous and stable combustion, and good shape retention.

[0040] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
