Description

Technical Field

[0001] The invention belongs to the technical field of microcapsule penetration, and in particular relates to a microcrystalline emulsification process control method. Background Art

[0002] In 1983, American scholars proposed the famous "brick wall theory" of skin barrier. The stratum corneum cells and cells of the skin form a natural protective barrier for the human body through lipids and natural moisturizing factors. In 2011, the global progress in skin immunology made a major discovery that when the epidermis is intact, the gaps between skin cells and the pores of hair follicles are about 8μm-10μm, while the pores of bacteria and fungi in the air are all above 10μm, and normal skin fungi or bacteria cannot enter. When the skin barrier is damaged, the gaps between skin cells and the pores of hair follicles will be greater than 10μm, and fungi and bacteria will enter the dermis and trigger an immune inflammatory response. When the skin barrier is damaged, it is divided into three types: mild damage, moderate damage and severe damage. The symptoms of mild damage are dryness, tightness, and oiliness. , blackheads, uneven skin tone, dull yellow, enlarged pores, poor absorption, dry lines; moderately damaged redness, itching, peeling, spots, closed comedones, fine lines, severely damaged allergies, stinging, itching, red blood streaks, acne, sagging, wrinkles, traditional creams and lotions are all made of oil-in-water or water-in-oil pastes. Due to the large particle size of this traditional encapsulation technology, it can only provide moisturizing protection on the surface of human skin, but traditional creams and lotions cannot penetrate into the dermis for deep protection and cannot bring into play the advantages of the product. The present invention controls the prepared cream and lotion to be precisely cut at different temperatures and times through a process program, and encapsulates them into microspheres. The microsphere molecules are controlled to be below 5μm, and enter the dermis through the normal skin pores for deep protection.

[0003] Therefore, based on the above technical problems, it is necessary to design a microcrystalline emulsification process control method. Summary of the invention

[0004] The purpose of the present invention is to provide a microcrystalline emulsification process control method, which aims to solve the problem in the prior art that the prepared cream emulsion cannot be accurately cut at different temperatures and different times through process control, wrapped into microspheres, the microsphere molecules are controlled to be below 5μm, and enter the dermis through normal skin pores for deep protection.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0006] A microcrystalline emulsification process control method includes preparing two phases of raw materials, wherein the raw materials of the phase A are oil phase and the raw materials of the phase B are water phase;

[0007] The preparation method comprises the following steps:

[0008] Step 1: Add phase A to the oil pan, heat, stir and raise the temperature to 80-85℃;

[0009] Step 2: Add phase B to the water pot, stir and heat to 85-90℃;

[0010] Step 3: Add phase B to the homogenizer, then add phase A, and stir at 10r / min-25r / min for 5min-15min;

[0011] Step 4: Cool down to 75°C, stir at 15r / min-35r / min for 10min-35min; homogenize at 15r / min-35r / min for 1min-5min;

[0012] Step 5: Cool down to 55°C, stir at 20r / min-45r / min for 25min-45min; homogenize at 20r / min-45r / min for 2min-8min;

[0013] Step 6: Cool down to 45℃, stir at 45r / min-60r / min for 2min-10min;

[0014] 30r / min-80r / min homogenization 1min-10mi.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. In this scheme, through a specific microcrystalline emulsification process control method, including the separate preparation of phase A (oil phase) and phase B (water phase) raw materials, as well as stirring, homogenizing and other operations at different temperatures and times, the cream lotion can be accurately cut and wrapped into microspheres, so that the microsphere molecules are controlled below 5μm. Such microspheres can enter the dermis through normal skin pores for deep protection, giving full play to the advantages of the product and solving the problem that traditional cream lotions cannot deeply protect the skin. Specifically, the separate preparation of phase A and phase B raw materials helps to accurately process their respective characteristics and ensure that the raw materials meet the standards. For example, the amount and performance of additives can be accurately controlled in the production of industrial lubricants.

[0017] 2. In this scheme, heating and stirring phase A to 80-85°C can promote the dispersion of oil phase components and activate active ingredients, such as stimulating antioxidant activity when producing certain functional oil products. Phase B is stirred and heated to 85-90°C, which can kill microorganisms to ensure sanitary quality and promote the role of surfactants to improve emulsification ability, such as effective sterilization to ensure safety in the preparation of cosmetic emulsions. Phase B is first added to the homogenizer and then phase A, and the stirring speed and time are controlled to reduce agglomeration and avoid emulsion structure damage, such as improving the hiding power and adhesion of the paint in the production of paint emulsions. Stirring and homogenizing at different temperatures, such as cooling to 75°C, 55°C, and 45°C, can increase the viscosity of the emulsion, enhance stability, optimize particle size distribution, improve fineness, enhance adhesion, consolidate the emulsion structure, and ensure quality consistency, such as the corresponding effects in the production of emulsion pesticides, food emulsions, emulsion adhesives, etc. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] Example 1

[0022] See also Figure 1 , the present invention provides the following technical solutions:

[0023] A microcrystalline emulsification process control method includes preparing two phases of raw materials, wherein the raw materials of the phase A are oil phase and the raw materials of the phase B are water phase;

[0024] The preparation method comprises the following steps:

[0025] Step 1: Add phase A to the oil pan, heat, stir and raise the temperature to 80-85℃;

[0026] Step 2: Add phase B to the water pot, stir and heat to 85-90℃;

[0027] Step 3: Add phase B to the homogenizer, then add phase A, and stir at 10r / min-25r / min for 5min-15min;

[0028] Step 4: Cool down to 75°C, stir at 15r / min-35r / min for 10min-35min; homogenize at 15r / min-35r / min for 1min-5min;

[0029] Step 5: Cool down to 55°C, stir at 20r / min-45r / min for 25min-45min; homogenize at 20r / min-45r / min for 2min-8min;

[0030] Step 6: Cool down to 45℃, stir at 45r / min-60r / min for 2min-10min; homogenize at 30r / min-80r / min for 1min-10min.

[0031] In a specific embodiment of the present invention, the raw materials of phase A (oil phase) and phase B (water phase) are separately prepared, which helps to accurately process the characteristics of the oil phase and the water phase. For example, the components in the oil phase may have specific requirements for temperature and stirring conditions, and the components in the water phase may focus more on solubility and stability. Separate preparation can facilitate quality inspection and adjustment of each phase to ensure that the raw materials put into the emulsification process meet the standards. For example: in the production of industrial lubricants, the oil phase may contain a variety of complex additives. Separate preparation can accurately control the amount and performance of each additive;

[0032] Technical feature 1: Add phase A into the oil pan and heat and stir to raise the temperature to 80-85℃;

[0033] Promote the dispersion of solid particles or high-viscosity components that may exist in the oil phase, improve its fluidity and uniformity, and activate certain active ingredients in the oil phase so that they can play a better role in the subsequent emulsification process. For example, when producing certain functional oil products, specific temperatures can stimulate the activity of antioxidants;

[0034] Technical feature 2: Add phase B into a water pot and stir to raise the temperature to 85-90℃;

[0035] Kill microorganisms in the water phase, ensure the sanitary quality of the product, promote the full play of surfactants and other ingredients that may be added to the water phase, and improve the emulsification ability of the water phase. For example, in the preparation of cosmetic emulsions, high temperature can effectively sterilize and ensure the safety of product use;

[0036] Technical feature three: Add phase B into the homogenizer, then add phase A, and stir at 10r / min-25r / min for 5min-15min;

[0037] This order of adding materials can make use of the dispersibility of phase B to better accommodate phase A and reduce agglomeration. The appropriate stirring speed and time can avoid excessive shearing and destruction of the emulsion structure in the initial emulsification stage. For example, in the production of paint emulsions, the correct order of adding materials and stirring conditions can significantly improve the hiding power and adhesion of the paint.

[0038] Technical feature 4: Cool down to 75℃, stir at 15r / min-35r / min for 10min-35min; homogenize at 15r / min-35r / min for 1min-5min;

[0039] Moderate cooling can gradually increase the viscosity of the emulsion, which is conducive to the aggregation and stabilization of particles. Stirring and homogenization can further optimize the particle size distribution of the emulsion at this temperature and improve the fineness of the product. For example, in the preparation of emulsion pesticides, appropriate temperature and treatment can enhance the adhesion of pesticides on plant surfaces.

[0040] Technical feature 5: Cool down to 55℃, stir at 20r / min-45r / min for 25min-45min; homogenize at 20r / min-45r / min for 2min-8min;

[0041] At this temperature, the stability of the emulsion gradually increases. Long-term stirring and homogenization help eliminate possible small uneven areas. Lower temperatures can reduce energy consumption and equipment wear while ensuring the emulsification effect. For example, in the preparation of food emulsions such as ice cream raw materials, it can not only ensure the emulsification effect, but also reduce production costs.

[0042] Technical feature six: Cool down to 45℃, stir at 45r / min-60r / min for 2min-10min; homogenize at 30r / min-80r / min for 1min-10min;

[0043] The final cooling, stirring and homogenizing can consolidate the structure of the emulsion, making it stable during storage and use. Higher stirring and homogenizing speeds can make final fine adjustments to the emulsion to ensure consistent product quality. For example, in the production of emulsion adhesives, the final treatment can enable the adhesive to maintain good bonding properties under different environments.

[0044] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein by equivalents.
