Description

Technical Field

[0001] The invention relates to the field of production of low-temperature micro-water granular cosmetics, and in particular to a production process of low-temperature micro-water granular cosmetics and application thereof. Background Art

[0002] The micro-water index is a volume ratio, expressed in ppmv (V is the subscript, indicating that the parameter is volume), that is, the volume of water contained in every million parts of gas unit volume. Because it contains very little water, it is called micro-water. In the production process of cosmetics, water is a very critical ingredient. It is not only because of its good solubility, but also because it is an important moisturizing substance. Most cosmetics such as shampoos, bath gels, various creams and lotions contain a lot of water, and water plays an important role in these cosmetics. The quality of water used in the production of cosmetics directly affects the quality of the cosmetics production process and the final product.

[0003] At present, most cosmetic products on the market use traditional high-temperature (about 80°C) emulsification processing methods, which often cause thermal denaturation and oxidation of the active ingredients in the raw materials during the production process, affecting the quality and effect of the products. The proportion of water in traditional cosmetics is relatively large, which increases the production cost. In addition, traditional production methods consume a lot of energy for the environment and often rely on the addition of chemical preservatives to ensure the stability of the product, which is inconsistent with the demand of modern consumers for green and environmentally friendly products. Therefore, there is an urgent need for a production technology that can effectively retain the active ingredients of the raw materials under low temperature conditions while avoiding the addition of excessive chemicals. A low-temperature micro-water granular cosmetic production process and its application and its application in cosmetics are proposed. Summary of the invention

[0004] In view of the above problems existing in the existing low-temperature micro-water production process, the present invention is proposed.

[0005] Therefore, the purpose of the present invention is to provide a low-temperature micro-water granular cosmetic production process and its application, which solves the problem that most cosmetic products on the market use traditional high-temperature (about 80°C) emulsification processing methods, which often cause thermal denaturation and oxidation of the active ingredients in the raw materials during the production process, affecting the quality and effect of the products. The proportion of water in traditional cosmetics is relatively large, which increases the production cost. In addition, the traditional production method consumes a lot of energy for the environment, and often relies on the addition of chemical preservatives to ensure the stability of the product, which is inconsistent with the demand of modern consumers for green and environmentally friendly products.

[0006] In order to achieve the above object, the present invention provides the following technical solutions:

[0007] A low-temperature micro-water granular cosmetic production process, specifically comprising the following steps:

[0008] S1. Raw material preparation: prepare raw materials and deionized water for cosmetics;

[0009] S2. Liquid raw material mixing: the raw materials of cosmetic formula are sheared, dispersed, impacted and mixed mechanically or physically by filtering, stirring, homogenizing, etc. to reduce the particle size, and different phases of materials are evenly distributed, mixed and dissolved in water according to a certain order of addition to obtain a mixture of liquid raw materials for cosmetics (filtration: remove impurities and microorganisms through a 0.22μm filter membrane. Viscosity: <5000mPa·s);

[0010] S3, freeze dehydration, put the prepared cosmetic liquid raw material mixture into a vacuum environment, and use freeze dehydration technology to remove the moisture in the cosmetic liquid raw material, so that the active ingredients in the raw material can be retained to the maximum extent without being subjected to heat treatment, while not destroying the structure and active ingredients of the raw material.

[0011] Preferably, the freeze dehydration technology in S3 specifically includes the following stages:

[0012] 1. Freezing stage

[0013] Purpose: To quickly freeze liquid raw materials into solid state;

[0014] Temperature control: Freezing temperature: -40℃ to -60℃ (depending on the characteristics of raw materials);

[0015] Cooling rate: 2℃-5℃ per minute to avoid the formation of large ice crystals;

[0016] Time: 2-4 hours (depending on product thickness and ingredients);

[0017] Key point: Rapid freezing forms uniform small ice crystals, which facilitates subsequent sublimation;

[0018] The particle shape can be selected before freezing, such as making freeze-dried particle molds;

[0019] 2. Primary drying stage (sublimation drying)

[0020] Turn on the vacuum pump to reduce the air pressure inside the freeze-drying box until the inside of the freeze-drying box is in a high vacuum state. At the same time, keep the low temperature inside the freeze-drying box and keep the items in the box frozen to prevent overflowing from the container. The ice will begin to sublimate, and the sublimated water vapor will form ice crystals in the condenser; pressure range: 50Pa to 200Pa (extremely low pressure environment);

[0021] Purpose: To convert ice directly into water vapor by sublimation, removing 80%-90% of the water.

[0022] Reason: The low-pressure environment reduces the sublimation temperature of ice (usually between -20°C and 0°C), thus preventing the active ingredients from being inactivated by heating;

[0023] Under vacuum, the sublimation point of ice is significantly reduced (0°C under standard atmospheric pressure), and sublimation drying is completed at low temperature.

[0024] Pressure change: At the beginning, the pressure is gradually reduced from atmospheric pressure to below 200Pa;

[0025] The pressure is maintained at 50-200Pa to avoid the collapse of the sample structure due to excessive sublimation rate;

[0026] 3. Analytical drying (second drying stage)

[0027] Turn on the heating system to raise the temperature of the shelf in the freeze-drying box, continuously supplying the heat required for ice sublimation to facilitate the evaporation of water until the product temperature coincides with the shelf temperature and reaches dryness. Pressure range: 10Pa to 50Pa (extremely low pressure environment);

[0028] Purpose: Remove the remaining bound water and reduce the moisture content of the material to <3-6%;

[0029] Reason: Bound water is tightly bound to the material molecules, requiring higher temperature and lower pressure to break the forces between molecules;

[0030] Lowering the pressure promotes the rapid diffusion of water vapor away from the surface of the material, while avoiding adverse reactions such as oxidation;

[0031] Pressure change: The pressure of primary drying is further reduced to 10-50Pa to prevent high temperature from damaging heat-sensitive components.

[0032] A low-temperature micro-water granular cosmetic production process application, the low-temperature micro-water production technology is particularly suitable for oily skin care products, especially cosmetics that require precise oil control and removal of excess oil, can better retain natural active ingredients and improve the use effect of the product. Taking Maetfiy cleansing pills as an example, this product is produced through low-temperature micro-water technology, which can effectively remove excess oil and clean pores while maintaining the natural water-oil balance of the skin. The proportion of water in the product ingredients is as low as 5.74%, which greatly reduces the cost and instability caused by water in traditional products.

[0033] In the above technical solution, the technical effects and advantages provided by the present invention are:

[0034] 1. Improve product effects: Through low-temperature micro-water production technology, the effective ingredients in the raw materials are better retained, avoiding the loss of activity and oxidation in the traditional high-temperature emulsification process. The effect of the product is significantly improved, especially in terms of oil control and deep cleansing;

[0035] 2. Reduce production costs: The batch production volume of high-temperature emulsification will affect the production cost, while the low-temperature freezing process can produce small batches, multiple varieties, and customization at the same time, which greatly reduces the production cost and also reduces the demand for preservatives in the product;

[0036] 3. Environmental protection and energy saving: The low-temperature granule production process reduces packaging specifications, greatly reduces energy consumption, and meets the needs of modern consumers for environmentally friendly and green products;

[0037] In summary, the low-temperature micro-water production technology of the present invention is an innovative technology that can effectively retain the active ingredients in the raw materials without relying on traditional high-temperature treatment and improve the effect and stability of the product. At the same time, the green and environmentally friendly characteristics of the technology also meet the needs of modern consumers for natural, safe and environmentally friendly products, and has broad application prospects and market value.

Obviously, the drawings described below are only some embodiments recorded in the present invention. For ordinary technicians in this field, other drawings can also be obtained based on these drawings.

[0039] Figure 1 It is a framework diagram of the present invention. DETAILED DESCRIPTION

[0040] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0041] The present invention provides Figure 1 The production process of a low-temperature micro-water granular cosmetic shown in the figure specifically comprises the following steps:

[0042] S1. Raw material preparation: prepare raw materials and deionized water for cosmetics;

[0043] S2. Liquid raw material mixing: the raw materials of cosmetic formula are sheared, dispersed, impacted and mixed mechanically or physically by filtering, stirring, homogenizing, etc. to reduce the particle size, and different phases of materials are evenly distributed, mixed and dissolved in water according to a certain order of addition to obtain a cosmetic liquid raw material mixture (viscosity: <5000mPa·s);

[0044] S3, freeze dehydration, placing the prepared cosmetic liquid raw material mixture in a vacuum environment, and using freeze dehydration technology to remove moisture from the cosmetic liquid raw materials, so that the active ingredients in the raw materials are retained to the maximum extent without being subjected to heat treatment, while not destroying the structure and active ingredients of the raw materials; (water content: <6%).

[0045] Low-temperature micro-water production process: Through vacuum low-temperature processing technology, water is removed under low-temperature vacuum negative pressure conditions, and the active ingredients in the raw materials are retained. This is impossible to achieve with traditional high-temperature production technology. The micro-water formula makes the product not only more concentrated and more effective, but also able to maintain the stability of the product for a longer period of time, reducing or eliminating the use of preservatives;

[0046] Optimization of micro-water formula: reducing the proportion of water in traditional products, greatly reducing production costs, while making the product more concentrated and stable;

[0047] Green and environmentally friendly production method: does not rely on high temperature or chemical preservatives, conforms to modern environmental protection and green consumption trends, and reduces the impact on the environment.

[0048] At the same time, the freeze dehydration technology in S3 specifically includes the following stages:

[0049] 1. Freezing stage

[0050] Purpose: To quickly freeze liquid raw materials into a solid state.

[0051] Pressure range: atmospheric pressure (approximately 101,325Pa or 760Torr).

[0052] Purpose: To quickly freeze the water in the material into solid ice in preparation for the sublimation drying stage.

[0053] Reason: To maintain atmospheric pressure to avoid water loss due to evaporation in a vacuum environment.

[0054] Under low temperature conditions (-40℃ to -60℃), water is completely frozen to form tiny ice crystals, providing a uniform starting point for subsequent sublimation.

[0055] 2. Primary drying stage (sublimation drying)

[0056] Pressure range: 50Pa to 200Pa (extremely low pressure environment).

[0057] Purpose: To convert ice directly into water vapor by sublimation, removing 80%-90% of the water.

[0058] Reason: The low-pressure environment lowers the sublimation temperature of ice (usually between -20°C and 0°C), preventing the active ingredients from being inactivated by heating.

[0059] Under vacuum, the sublimation point of ice is significantly reduced (0°C under standard atmospheric pressure), and sublimation drying is completed at a low temperature.

[0060] Pressure change: Initially, the pressure gradually decreases from atmospheric pressure to below 200Pa.

[0061] The pressure is maintained at 50-200Pa to avoid the collapse of the sample structure due to excessive sublimation rate.

[0062] 3. Analytical drying (second drying stage)

[0063] Pressure range: 10Pa to 50Pa (extremely low pressure environment).

[0064] Purpose: Remove the remaining bound water and reduce the moisture content of the material to <3%.

[0065] Reason: Bound water is tightly bound to the material molecules, requiring higher temperature and lower pressure to break the forces between the molecules.

[0066] Reducing the pressure promotes the rapid diffusion of water vapor away from the surface of the material, while avoiding adverse reactions such as oxidation.

[0067] Pressure change: The pressure of primary drying is further reduced to 10-50Pa to prevent high temperature from damaging heat-sensitive components.

[0068] 4. Packaging and Storage

[0069] Packaging: Pack the freeze-dried product in a sterile environment.

[0070] Packaging form: independent packaging or independent freeze-dried granule packaging.

[0071] Storage conditions: Temperature: Store at room temperature (active peptides, enzymes, and biological extracts should be refrigerated or frozen as required).

[0072] Humidity: <50% RH (avoid moisture absorption).

[0073] Sealing: Sealed packaging to prevent oxidation and moisture absorption.

Taking Maetfiy cleansing pills as an example, this product is produced through low-temperature micro-water technology, which can effectively remove excess oil and clean pores while maintaining the natural water-oil balance of the skin. The proportion of water in the product ingredients is as low as 5.74%, which greatly reduces the cost and instability caused by water in traditional products.

[0075] The technical effects of the present invention are:

[0076] Improve product effects: Through low-temperature micro-water production technology, the effective ingredients in the raw materials are better preserved, and the effects of the products are significantly improved, especially in terms of oil control, deep cleansing, anti-aging, etc.;

[0077] Reduce production costs: Water and raw material activity decrease, and the proportion of raw material oxidation is greatly reduced, which greatly reduces production costs and also reduces the demand for preservatives in products;

[0078] Environmental protection and energy saving: low-temperature production process, simultaneous production of multiple varieties and small batches, significant reduction in single product packaging capacity, and single quantitative use greatly reduce energy consumption and meet the needs of modern consumers for environmentally friendly and green products;

[0079] In summary, the low-temperature micro-water production technology of the present invention is an innovative technology that can effectively retain the active ingredients in the raw materials without relying on traditional high-temperature treatment and improve the effect and stability of the product. At the same time, the green and environmentally friendly characteristics of the technology also meet the needs of modern consumers for natural, safe and environmentally friendly products, and has broad application prospects and market value.
