Description

Technical Field

[0001] The present invention belongs to the technical field of cosmetic preparation, and in particular relates to a homogenizing emulsification system and method for preparing cosmetics. Background Art

[0002] Cosmetics, also known as skin care products, refer to preparations used on the human body to beautify, preserve or change a person's appearance, or to clean, dye, wipe, correct or protect the skin, hair, nails, eyes. Emulsification is the process of evenly dispersing a liquid in another immiscible liquid in the form of extremely tiny droplets. Emulsification is a liquid interface phenomenon. Two immiscible liquids, such as oil and water, are divided into two layers in a container, with the oil with a lower density in the upper layer and the water with a higher density in the lower layer. If an appropriate surfactant is added and stirred strongly, the oil is dispersed in the water to form an emulsion. This process is called emulsification. Emulsions are the most widely used dosage form in cosmetics, ranging from water-like fluids to viscous creams. When the existing emulsifying device is used, it is not easy to uniformly process the raw materials at the top and bottom of the emulsifying tank, and the emulsification effect becomes poor, resulting in poor efficiency in forming particle dispersion for the two immiscible liquids. The solid particles used as emulsifiers need to be processed again, which is not conducive to the rapid effectiveness of the emulsifier and the emulsification quality. Summary of the invention

[0003] Due to the deterioration of the emulsification effect of the raw materials, the efficiency of forming particle dispersion of two immiscible liquids is poor, and the solid particles used as emulsifiers need to be processed again, which is not conducive to the rapid effectiveness and emulsification quality of the emulsifier. In view of the shortcomings of the prior art, the present invention provides a homogenous emulsification system and method for preparing cosmetics.

[0004] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a homogenizing emulsifying system for preparing cosmetics, comprising the emulsifying tank, a stirring device, a temperature control system, a homogenizing system, and a pipeline transport.

[0005] Homogenizing emulsification method for preparing cosmetics: The specific emulsification steps are as follows:

[0006] S1. Heat and stir 10% oil, 3% fat, 2% wax, 20% emulsifier and other oil-soluble ingredients in an emulsifying tank to melt them and produce an oil phase;

[0007] S2, heating and stirring 20% ​​of deionized water, 30% of moisturizer, 2% of alkali, and 20% of water-soluble emulsifier in an emulsification tank to make them swell and produce a water phase, and at the same time, the oil-soluble components and the water-soluble components are stirred and pre-emulsified, and then uniformly homogenized and emulsified;

[0008] S3. Cool the material. During the cooling process, auxiliary materials such as 5% flavor and 4% preservative can be added.

[0009] Preferably, in S1, during operation, the emulsification tank must be cleaned and disinfected. The emulsification tank is specifically composed of an oil pot, a water pot, and a main pot. After the oil-soluble components in S1 and the water-soluble components in S2 are placed in the oil pot and the water pot, respectively, the water pot and the oil pot should be heated, and the heating temperature is controlled at 70°C-75°C. The overall temperature is regulated by a thermometer control system in a control cabinet. During the heating process, the stirring device needs to be started, the stirring speed is 160-180 rpm, and the stirring time is controlled between 30 minutes and 35 minutes.

[0010] Preferably, when the water pot is heated, if the water phase contains a water-soluble polymer, 5% propylene glycol can be added and dispersed into the water phase. Continuous stirring is required during the period. During stirring, the thermometer control system is adjusted to heat the temperature to 85°C-90°C, and this temperature is maintained for 15 minutes to 20 minutes.

[0011] Preferably, when the raw materials in the oil pot and the water pot are stirred and heated to the required temperature, the vacuum system can be turned on to make the negative pressure in the main pot 0.06Mpa, and the oil-soluble raw materials and water-soluble component raw materials in the oil pot and the water pot are sucked into the main pot and stirred at the same time. The stirring time is controlled at 5 minutes to 8 minutes, and the stirring speed is 100-150 rpm.

[0012] Preferably, the homogenizing system is turned on to homogenize and emulsify the raw materials, the homogenizing and emulsifying time is set to 15 minutes, the stirring of the homogenizing and emulsifying is set to 10 minutes, and the rotation speed is 120-150 rpm. When the emulsification requirements are met, the homogenizing system can be turned off.

[0013] Preferably, in S3, when cooling the raw materials, the cooling water valve needs to be opened to circulate and cool the main pot, and the internal stirring speed slows down as the temperature drops, wherein the negative vacuum degree should be maintained at about 0.05Mpa, and when the temperature drops to 50°C, 5% flavor, 2% active ingredient, 4% high temperature-intolerant preservative, 7% thickener, 10% nourishing agent, 5% nutrient, 3% medicine, 10% antioxidant, and other auxiliary materials may be added.

[0014] Preferably, continuous stirring is required during the addition of auxiliary materials, and the stirring speed is 100-150 rpm. When the temperature drops to 35°C-40°C, the discharging conditions are met, and the cooling water valve is immediately closed, and the discharge valve on the discharge pipe is opened to start discharging the emulsified raw materials.

[0015] Preferably, the cosmetic emulsified raw materials discharged from the main pot need to be filtered because thickeners are added to the raw materials. The filtering operation needs to be delicate. By selecting a 270-mesh filter cloth, the homogenized and emulsified raw materials are uniformly filtered. During the filtering process, they need to be filtered naturally without applying weight or squeezing by hand or other external force. Finally, they are filled. The filled cosmetic raw materials need to be left for more than 24 hours.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] The present application reorganizes two materials into a uniform phase, and the rotor runs at a high speed to produce a high shear speed and high frequency mechanical effect, while bringing strong kinetic energy, so that the material is subjected to the combined effects of strong mechanical shear, liquid layer friction, centrifugal extrusion, etc. in a short period of time, and gradually forms suspension, emulsification and foam. Under high shear speed, the solid phase, liquid phase and gas phase that do not dissolve in each other are instantly dispersed and emulsified under the joint action of relatively mature technology and appropriate additives. Finally, the effect of stable emulsification can be effectively and quickly achieved, so that the product quality at the processing and production site is very high, mainly to achieve the efficient, rapid and uniform conversion of one or more phases of liquid and solid into another insoluble continuous phase. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] Figure 1 The present invention is a flow chart of the preparation method. DETAILED DESCRIPTION

[0019] Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in the field without making any creative work shall fall within the scope of protection of the present invention.

[0020] The technical solution provided by the present invention is a homogenizing emulsifying system for preparing cosmetics, comprising an emulsifying tank, a stirring device, a temperature control system, a homogenizing system, and pipeline transportation.

[0021] Homogenizing emulsification method for preparing cosmetics: The specific emulsification steps are as follows:

[0022] S1. Heat and stir 10% oil, 3% fat, 2% wax, 20% emulsifier and other oil-soluble ingredients in an emulsifying tank to melt them and produce an oil phase;

[0023] S2, heating and stirring 20% ​​of deionized water, 30% of moisturizer, 2% of alkali, and 20% of water-soluble emulsifier in an emulsification tank to make them swell and produce a water phase, and at the same time, the oil-soluble components and the water-soluble components are stirred and pre-emulsified, and then uniformly homogenized and emulsified;

[0024] S3. Cool the material. During the cooling process, auxiliary materials such as 5% flavor and 4% preservative can be added.

[0025] In S1, during operation, the emulsification tank must be cleaned and disinfected. The emulsification tank is specifically composed of an oil pot, a water pot, and a main pot. After the oil-soluble components in S1 and the water-soluble components in S2 are placed in the oil pot and the water pot respectively, the water pot and the oil pot should be heated. The heating temperature is controlled at 70℃-75℃. The overall temperature is regulated by the thermometer control system of the control cabinet. The stirring device needs to be started during the heating process. The stirring speed is 160-180 rpm and the stirring time is controlled between 30 minutes and 35 minutes.

[0026] What needs to be added to the above is that when heating is carried out through a thermometer control system, excessive heating or prolonged heating should be avoided to prevent the raw materials from oxidizing and deteriorating after being overheated. At the same time, the stirring device can speed up the mixing and dissolution of the materials while ensuring that the raw materials are heated evenly.

[0027] When the water pot is heated, if the water phase contains water-soluble polymers, 5% propylene glycol can be added and dispersed into the water phase. During the period, continuous stirring is required. During the stirring, the thermometer control system is adjusted to heat the temperature to 85°C-90°C, and this temperature is kept warm for 15 minutes-20 minutes. When the raw materials in the oil pot and the water pot are heated to the required temperature through stirring and temperature, the vacuum system can be turned on to make the negative pressure in the main pot 0.06Mpa, and the oil-soluble raw materials and water-soluble raw materials in the oil pot and the water pot are sucked into the main pot and stirred at the same time. The stirring time is controlled at 5 minutes-8 minutes, and the stirring speed is 100-150 rpm. The homogenization system is turned on to homogenize and emulsify the raw materials. The homogenization emulsification time is set to 15 minutes, and the stirring of homogenization and emulsification is set to 10 minutes, and the speed is 120-150 rpm. When the emulsification requirements are met, the homogenization system can be turned off. In S3, when cooling the raw materials, the cooling water valve needs to be opened to circulate and cool the main pot, and the internal stirring speed changes with the temperature. When the temperature drops to 50℃, you can add 5% flavor, 2% active substance, 4% high temperature resistant preservative, 7% thickener, 10% nourishing agent, 5% nutrient, 3% medicine, 10% antioxidant and other auxiliary materials. Stirring should be continued during the addition of auxiliary materials. The stirring speed is 100-150 rpm. When the temperature drops to 35℃-40℃, the discharging conditions can be met. Close the cooling water valve immediately, open the discharge valve on the discharge pipe, and start to discharge the emulsified raw materials. Discharge the emulsified cosmetic raw materials from the main pot. Since thickeners are added to the raw materials, the raw materials need to be filtered. The filtering operation needs to be meticulous. By selecting a 270-mesh filter cloth, the homogenized and emulsified raw materials are uniformly filtered. During the filtration process, they need to be filtered naturally. Do not use your hands or other external forces to apply weight or squeeze. Finally, fill them. The cosmetic raw materials after filling need to be placed for more than 24 hours.

[0028] It should be added that: there are five groups of stirring blades in the stirring device, each group consists of four stirring blades, the stirring direction is vertical rotation stirring, and multiple groups of stirring blades can fully mix a variety of raw materials.

[0029] Among the above schemes: the main purpose is to efficiently, quickly and evenly convert one or more phases of liquid and solid into another insoluble continuous phase. When the fineness of one or more materials reaches the micron level or even the nanometer level, it can be considered that the effect achieved by the system is uniform, and the two materials are recombined into a uniform phase. Due to the fast running speed of the rotor, high shear speed and high frequency mechanical effects are generated, and strong kinetic energy is brought at the same time, so that the material is subjected to strong mechanical shear, liquid layer friction, centrifugal extrusion and other comprehensive effects in a short time, and gradually forms suspension, emulsification and foam. Under high shear speed, the solid phase, liquid phase and gas phase that do not dissolve in each other are instantly evenly dispersed and emulsified under the joint action of relatively mature technology and appropriate additives. Finally, the effect of stable emulsification can be effectively and quickly achieved, so that the product quality at the processing and production site is very high.
