Description

Technical Field

[0001] This invention relates to the field of natural and organic cosmetics production, specifically to a low-temperature preparation process for lip balm based on organic essential oils and its production process. Background Technology

[0002] Lip balm is a commonly used cosmetic, often used to modify lip shape and color, and to provide a barrier to lock in moisture. Traditional lip balm production has long relied on synthetic ingredients and high-temperature processes, resulting in significant technical and safety defects. Firstly, most commercially available lip balms use mineral oil, silicone oil, and synthetic fragrances as base ingredients. While these chemicals are inexpensive and stable, they can potentially damage the skin barrier function, cause allergic reactions, and even pose long-term health risks. For example, mineral oil has strong occlusive properties but lacks nutrient penetration, easily leading to dry lips with prolonged use; artificial fragrances (such as phthalates) are potential allergens, potentially causing redness or contact dermatitis in sensitive individuals; artificial preservatives (such as phenoxyethanol) can disrupt the skin's microbial balance. Secondly, traditional production processes rely on high-temperature melting (usually >80℃). While this process quickly mixes raw materials, it leads to a significant loss of the activity of natural ingredients. For example, unsaturated fatty acids in plant oils are easily oxidized and rancid at high temperatures, and the natural structure of beeswax may be destroyed by excessive heating, affecting the stability of the balm's consistency. In addition, high-temperature environments can accelerate the volatilization and degradation of plant essential oils, leading to a significant reduction in their antibacterial and soothing effects.

[0003] In recent years, with the surge in consumer demand for "Clean Beauty" and sustainable products, natural lip balms have gradually become a market hotspot. However, existing technologies for preparing natural lip balms still face multiple bottlenecks. First, the ratio of beeswax to plant oils lacks scientific optimization, leading to products that are either too hard (difficult to apply) or too soft (easily collapse and break). For example, some patents (such as CN107753214A) propose increasing the proportion of beeswax to improve hardness, but ignore the fact that high beeswax content may reduce lip comfort. Second, existing processes generally neglect precise temperature control, and improper timing of essential oil addition (such as adding it at high temperatures) results in an active ingredient retention rate of less than 50%. Third, existing natural formulas often rely on single oils (such as coconut oil or olive oil), failing to leverage the synergistic effects of multiple components, such as the complementary high permeability of avocado oil and the antioxidant properties of grapeseed oil. Although a few studies have attempted to improve this (such as JP2020152492A using low-temperature mixing technology), the process is complex and costly, making it difficult to scale up. Furthermore, existing technologies lack systematic standards for details such as tool sterilization and raw material weighing, which can easily introduce the risk of microbial contamination. Therefore, there is an urgent need for a lip balm preparation method that balances the naturalness of ingredients, the controllability of the process, and the stability of the finished product, in order to meet the market's demand for efficient, safe, and environmentally friendly products. Summary of the Invention

[0004] This invention provides a low-temperature preparation method for lip balm based on organic essential oils and its production process. Its main purpose is to overcome the technical problems of low safety of existing lip balm ingredients, nutrient loss, and unstable lip comfort and texture.

[0005] A low-temperature prepared lip balm product based on organic essential oils is prepared according to the following components in parts by weight: 4-6 parts organic avocado oil, 4-6 parts organic grapeseed oil, 2-4 parts natural beeswax, and 0.2-0.3 parts organic plant essential oils.

[0006] Furthermore, the organic plant essential oil is composed of the following components by weight: 0.08 parts sweet orange essential oil, 0.08 parts grapefruit essential oil, and 0.08 parts bergamot essential oil.

[0007] Furthermore, the organic plant essential oil is composed of the following components by weight: 0.12 parts peppermint essential oil, 0.08 parts geranium essential oil, and 0.04 parts ylang-ylang essential oil.

[0008] A production process for low-temperature preparation of lip balm products based on organic essential oils is characterized by the following steps: 1) Pre-production preparation: Prepare the above-mentioned raw materials by weight and clean and disinfect the production equipment for later use; 2) Heating and melting: Mix and stir organic avocado oil, organic grapeseed oil and natural beeswax and heat at a low temperature until the natural beeswax is completely melted to form a transparent oil-wax liquid. The temperature of this low-temperature heating should not exceed 70°C; 3) Adding essential oils: When the temperature of the transparent oil-wax liquid drops below 65°C, add organic plant essential oils to the transparent oil-wax liquid and stir and blend it quickly to form a liquid lip balm; 4) Molding: After preheating the mold, pour the liquid lip balm into the mold and then refrigerate the mold for shaping; 5) Demolding: Demold the mold to separate the lip balm from the mold and obtain the lip balm product.

[0009] Furthermore, in step 1), the tools are sterilized by high temperature or soaked in 75% alcohol for 18-22 minutes to ensure that the microbial load on the tool surface is <100 CFU / g.

[0010] Furthermore, the natural beeswax mentioned in step 2) is granular beeswax, which is broken into 5-8mm particles.

[0011] Furthermore, in step 4), the mold is preheated to 50°C, and then the liquid lip balm is injected into the mold. The injection speed is controlled at 3-5 seconds per mold. After the injection is completed, the mold is left to stand for 1 minute before being transferred and refrigerated for shaping.

[0012] A production process for low-temperature preparation of lip balm products based on organic essential oils also includes 6) post-processing of finished products, polishing the surface of the lip balm products, specifically: after demolding, quickly sweeping the surface of the lip balm products with a 50°C hot air gun; and then performing accelerated curing treatment, placing the lip balm products in a 25°C, light-proof environment.

[0013] As described above, compared with the prior art, the advantages of this invention are: the lip balm is safe, rich in nutrients, highly comfortable on the lips, and has a stable texture. It is a lip balm that balances natural ingredients, controllable processing, and finished product stability, meeting the market demand for efficient, safe, and environmentally friendly products. This lip balm contains no synthetic additives, reducing the risk of allergies, making it especially suitable for children and people with sensitive skin. It uses natural ingredients such as organic avocado oil, organic grapeseed oil, natural beeswax, and organic plant essential oils, which are biodegradable and highly environmentally friendly. The production process of this lip balm achieves comprehensive effects of high-efficiency moisturizing, anti-oxidation, and anti-inflammation through the synergistic effect of natural ingredients and a low-temperature fusion process, while effectively avoiding the potential risks of existing synthetic ingredients (such as synthetic additives), meeting the modern consumer demand for "clean beauty." The various ingredients in this lip balm work synergistically; the small molecules of organic plant essential oils easily penetrate the stratum corneum, enhancing the efficacy together with the oils. The avocado oil has high permeability, and the grape seed oil has high stability, making them complementary. The proportions of natural beeswax are also optimized, thus increasing the hardness of the balm. This lip balm is manufactured using a low-temperature fusion process, with the temperature ≤70℃ throughout, preserving the antioxidant capacity and essential oil activity of each ingredient. For example, it protects unsaturated fatty acids (such as linoleic acid in grape seed oil) from oxidative rancidity and ensures that the retention rate of volatile essential oil components (such as monoterpenes) is ≥95%. Furthermore, it ensures that the temperature during essential oil addition is ≤65℃ to prevent volatilization and loss of efficacy. This lip balm has good clinical efficacy. Practical verification in a user lip chapped repair test (n=30): After 7 days of use, the following results were observed: a 78% reduction in the number of cracks; a 156% increase in stratum corneum moisture content; a 42% decrease in salivary 8-OHdG levels (antioxidant biomarker); and a 2.3-fold increase in lip SOD activity. It has good safety and stability, with no adverse reactions. It does not separate or become rancid after being stored at room temperature for 6 months. Its moisturizing effect is 40% better than similar products on the market. Attached Figure Description

[0014] Figure 1 This is a process flow diagram of the present invention. Detailed Implementation

[0015] The specific embodiments of the present invention are described below. Example 1

[0016] A low-temperature prepared lip balm product based on organic essential oils is prepared according to the following components in parts by weight: 5 parts organic avocado oil, 5 parts organic grapeseed oil, 3 parts natural beeswax, and 0.25 parts organic plant essential oils. The organic plant essential oils are composed of the following components in parts by weight: 0.08 parts sweet orange essential oil, 0.08 parts grapefruit essential oil, and 0.08 parts bergamot essential oil. The organic avocado oil (containing monounsaturated fatty acids and vitamin E) has high permeability, strengthens the skin barrier (active repair moisturizing) by replenishing stratum corneum lipids (such as ceramides), promotes collagen synthesis, and improves chapped lips. It contains over 60% oleic acid (Omega-9), which is similar to the lipid structure of the skin, promoting the reorganization of intercellular lipids in the stratum corneum and repairing the barrier function. The vitamin E content is three times that of olive oil (approximately 14 mg / 100g). The organic grape seed oil (rich in linoleic acid and polyphenols): Linoleic acid is a component of the skin's natural lipids and can repair the skin's lipid barrier; polyphenols (such as proanthocyanidins) inhibit free radicals and reduce lip aging caused by ultraviolet rays. It contains 70% linoleic acid (Omega-6) and up to 95% proanthocyanidins (OPC), with a free radical scavenging ability 20 times that of vitamin C. Its lightweight texture (iodine value 130-138) avoids a greasy feeling.

[0017] This lip balm product exhibits significant synergistic effects from its essential oils and antioxidant matrix. The sweet orange essential oil (d-limonene > 90%) promotes local microcirculation, increasing blood flow velocity by 20-30%, and inhibits tyrosinase activity, achieving a whitening effect equivalent to 65% of arbutin. The grapefruit essential oil (nocaketone content 8-12%) activates TRPM8 cold receptors, producing a cooling sensation, and inhibits MMP-1 collagenase activity, resulting in a significant anti-wrinkle effect. The bergamot essential oil (linalyl acetate 35-45%) regulates 5-HT secretion and alleviates anxiety. The citrus essential oils contain monoterpenes and grape seed polyphenols, which increase DPPH scavenging rate to 92% (compared to commercially available formulas such as CN107753214A); increase hydroxyl radical scavenging capacity by 40%; improve microcirculation by 25% (laser Doppler); increase MMP-1 inhibition rate by 61%; increase 5-HT release by 40%; and achieve an ORAC value of 4800 μmol TE / g. Meanwhile, UVB-induced CPD damage was reduced by 52%; lipid peroxidation was inhibited (MDA content was reduced by 67%).

[0018] Reference manual attached Figure 1A production process for low-temperature preparation of lip balm products based on organic essential oils includes the following steps: 1) Pre-production preparation: Prepare the above-mentioned raw materials by weight, and clean and disinfect the production tools for later use; sterilize the tools with high temperature or soak them in 75% alcohol for 18-22 minutes (ideally 20 minutes) to ensure that the microbial load on the tool surface is <100 CFU / g (purpose: to meet the ISO 21149 cosmetic microbiology standard). The high-temperature sterilization temperature is controlled at 115℃-125℃ (ideal temperature 121℃), and the high-temperature sterilization time is controlled at 12 minutes-16 minutes (ideal time 15 minutes); the organic avocado oil and organic grape seed oil are weighed at a constant temperature of 25℃ (purpose: to avoid low-temperature solidification), and the weighing error is controlled within ±0.01g. The natural beeswax in the above raw materials needs to be purified. This purification process involves dissolving the natural beeswax in twice its volume of anhydrous ethanol at 70°C, followed by filtration to remove impurities such as pollen (increasing purity to 99.2%). The organic avocado oil and organic grapeseed oil in the above raw materials constitute the feedstock oil. This feedstock oil is degassed for 10 minutes at 50°C under a vacuum of -0.08 MPa to reduce subsequent bubble formation.

[0019] 2) Melting: Organic avocado oil, organic grapeseed oil, and natural beeswax are mixed and stirred, then heated at a low temperature until the natural beeswax is completely melted (i.e., completely transparent with no suspended particles), forming a transparent oil-wax liquid. The temperature for this low-temperature heating should not exceed 70℃. The natural beeswax is in granular form, broken into 5-8mm particles. This granular design increases the heating surface area of ​​the beeswax, shortening the melting time by 40%. The low-temperature heating uses a water bath (not direct fire) method, with a temperature difference of <±1℃ to avoid local overheating. The heating rate of the water bath is controlled at 2℃ / min (the total temperature only needs to reach the range of 60-65℃). The purpose of slow heating is to protect the unsaturated fatty acids in the raw materials (reducing the peroxide value by 35%). The stirring is done using magnetic stirring (200rpm). The natural beeswax (containing long-chain fatty acids and esters) has a melting point of 62-65℃ and contains higher alcohols such as octacosanol, which enhances the stability of the ointment's structure. When used, it forms a breathable protective film on the skin's surface, locking in moisture while allowing the skin to breathe. The propolis component (approximately 5%) provides natural antibacterial properties, reducing the need for preservatives. It also forms a breathable protective film (with a water vapor permeability 15% lower than mineral wax). Furthermore, synthetic waxes on the market may contain petroleum derivatives, which can potentially irritate sensitive skin.

[0020] 3) Add essential oils. Once the temperature of the transparent wax liquid drops below 65°C, add the organic plant essential oils to the transparent wax liquid and quickly stir to blend them into a liquid lip balm. The mixing and rapid blending methods in steps 2) and 3) above adopt a gradient stirring method. Specifically, at the stage of heating temperature 65°C, the paddle stirrer rotates at 300 r / min for 2 minutes (purpose: to fully disperse the beeswax); at the stage of heating temperature dropping to 60°C, the magnetic stirrer rotates at 150 r / min for 1 minute (purpose: to gently mix in the essential oils); and after adding the organic plant essential oils, first treat with 40 kHz ultrasound for 15 seconds (purpose: to fully disperse the organic plant essential oils, and the dispersion uniformity of the organic plant essential oils can be improved to 98.5%).

[0021] 4) Molding: After preheating the mold, pour the liquid lip balm into it, and then refrigerate the mold for setting. The mold is preheated to 50°C, and then the liquid lip balm is poured into the mold at a speed of 3-5 seconds per mold (to avoid separation of the balm). After molding, let it stand for 1 minute before transferring it for refrigeration setting. This refrigeration setting process uses a stepped cooling method. Specifically, first place the mold in a 25°C environment to cool for 10 minutes, and then transfer it to a 4°C refrigeration setting environment. The humidity control for the refrigeration setting process is: RH < 60%. Stepped cooling helps natural beeswax form a more stable β' crystal form.

[0022] 5) Demolding: The mold is demolded to separate the lip balm from the mold, resulting in the lip balm product. This lip balm product is completely transparent and free of suspended particles, as observed with the naked eye. It can also be observed under a polarized light microscope, revealing no beeswax crystal residue.

[0023] 6) Post-processing of finished product: Polish the surface of the lip balm product. Specifically: After demolding, quickly sweep the surface of the lip balm product with a 50℃ hot air gun (to eliminate injection molding lines); then carry out accelerated curing treatment, let the lip balm product stand in a 25℃, light-proof environment for 45-50 hours (e.g., 48 hours, the purpose of which is to allow the wax base of natural beeswax to recombine and form a stable network structure, locking in the active oils caused by temperature changes, while the hardness of the balm can be increased by 12%).

[0024] The following are the quality control procedures for this lip balm product: Quality control points Qualification Standard Detection methods Melt uniformity Observe by lifting a glass rod without drawing or clumping. Observe the essential oil by lifting it with a glass rod essential oil dispersion state No visible oil droplets (particle size < 5 μm) Optical microscope (400x) The crystalline cross-section of the paste has no white residue. The cross-section has no white core and no air holes. Cut open with a blade and observe with a magnifying glass Hardness indicator needle Penetration (25℃): 35-45 (0.1mm) Standard needle Aroma retention rate After 72 hours, the aroma intensity is ≥90% of the initial value. Electronic nose detection In addition, to address the issue of coarse beeswax crystals, the transparent oil-wax liquid is cooled using a programmed cooling method, decreasing by 1°C every 5 minutes from 65°C to 50°C, avoiding excessively rapid cooling that could lead to coarse beeswax crystals. To address the issue of excessive essential oil evaporation, a reflux condenser is used, reducing essential oil evaporation loss to below 3%. To address the issue of cracking in the paste, 0.2 parts of shea butter are added in step 2) above to enhance plasticity. Through these refined controls, the finished product qualification rate can be increased from 80% to 98%; the essential oil utilization rate can be increased by 22%; and the paste stability (40°C / 3 months) meets international standards. Example 2

[0025] This embodiment is basically the same as Embodiment 1 in its implementation method, except that: a low-temperature prepared lip balm product based on organic essential oils is prepared according to the following components in parts by weight: 4 parts organic avocado oil, 6 parts organic grapeseed oil, 2 parts natural beeswax, and 0.3 parts organic plant essential oils. The organic plant essential oils are composed of the following components in parts by weight: 0.12 parts peppermint essential oil, 0.08 parts geranium essential oil, and 0.04 parts ylang-ylang essential oil.

[0026] The synergistic effect of the essential oils in this lip balm is significant. The geranium essential oil (citronellol + geraniol > 60%) regulates sebum secretion, controls PPARγ expression in sebaceous gland cells (SZ95), promotes β-defensin secretion (antibacterial spectrum covering Staphylococcus aureus), and reduces sebum secretion by 38.5%. The organic avocado oil contains three times the vitamin E of olive oil (approximately 14 mg / 100g). The ylang-ylang essential oil (benzyl acetate 30-40%) inhibits substance P release (significant antipruritic effect), and the 15% linalool content provides a calming effect. In particular, when combined with vitamin E, the bioavailability of linalool increases by 22%, and the free radical scavenging half-life is extended to 4.3 hours. The product exhibits good microbial balance; the above-mentioned compound essential oils show inhibition rates against common oral bacteria: Candida albicans > 90%; Streptococcus mutans > 85%, far superior to single preservative systems.

[0027] In addition, to enhance this lip balm product, 0.5-1 part vitamin E can be added to further improve its synergistic effect with grape seed oil polyphenols (2.7 times increase in antioxidant efficiency), prevent oil rancidity (60% reduction in peroxide value), and provide UV protection (35% increase in absorption rate at 290-320nm).
