Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0023] The terms "first", "second", etc. in the specification and claims of this application and the above-mentioned drawings are used to distinguish different objects, rather than to describe a specific order. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions.

[0024] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0025] In the embodiments of the present application, pH value refers to the acidity-base value, which is a symbol used in chemistry to measure the acidity-base ratio of a liquid.

[0026] See also Figure 1 , Figure 1 : is a flow chart of a method for preparing an anti-dandruff and antipruritic composition provided in an embodiment of the present application. As shown in the figure, the method for preparing the anti-dandruff and antipruritic composition may include the following steps:

[0027] S101. Put the components in phase A into the main production pot, adjust the speed to 10-12r / min, and start stirring.

[0028] In the embodiment of the present application, the components in phase A can be put into the main production pot, the rotation speed of the main production pot is adjusted to 10-12r / min, and stirring is started.

[0029] Optionally, the phase A includes: water, CAB, MLD PF, 1618C, AES and C11S.

[0030] In the embodiment of the present application, CAB may include: cocamidopropyl betaine, water. MLD PF may include sodium lauroyl sarcosinate, water. 1618C may include cetearyl alcohol. AES may include sodium laureth sulfate, water. C11S may include cocamidomethyl MEA, glycerin.

[0031] Among them, the proportions (%) of water, CAB, MLD PF, 1618C, AES and C11S in phase A can be: 32.7, 6, 2, 0.3, 15, 2.

[0032] S102, connecting the jacket in the main production pot to high-temperature steam, heating the temperature in the main production pot to 75-80°C, and stirring at this temperature until all components are evenly dissolved.

[0033] In the embodiment of the present application, the high temperature steam may be steam with a temperature higher than 75° C. For example, the high temperature steam may include steam with a temperature of 110-250° C.

[0034] Herein, heat preservation and stirring can be understood as stirring while maintaining the temperature at 75-80°C.

[0035] In the specific implementation, the jacket in the main production pot is connected to high-temperature steam, the temperature in the main production pot is heated to 75-80°C, and the temperature is kept and stirred until all components are evenly dissolved.

[0036] In the specific implementation, the speed cannot be adjusted too fast. If it is adjusted too fast, a large amount of foam will be generated, which will affect the subsequent process, prolong the production time, and affect the observation and confirmation of the material during the operation, resulting in uncontrollable quality. If the speed is adjusted too slowly, it will not be conducive to the dissolution of the surfactant and reduce the production efficiency. For example, in practical applications, when using a 3-5 ton production pot, the speed should be adjusted to 10-12r / min. The production temperature should be controlled at 75℃-80℃. Temperatures below 75℃ are likely to cause some solid raw materials to be unable to dissolve completely, and temperatures above 80℃ will increase production energy consumption and increase the time for heating and cooling, reducing production efficiency.

[0037] S103, pre-treating phase B with a cationic conditioning agent to obtain a treated phase B.

[0038] In a specific implementation, phase B may be pretreated with a cationic conditioning agent.

[0039] Optionally, the phase B comprises: KDMP, Quat 2240, 120E and water.

[0040] In the embodiment of the present application, KDMP may include: behenyl trimethyl ammonium chloride, isopropyl alcohol, water. Quat 2240 may include: polyquaternium-22, water, sodium benzoate. 120E may include guar hydroxypropyl trimethyl ammonium chloride.

[0041] The proportions (%) of KDMP, Quat 2240, 120E and water in phase B may be: 0.4, 0.7, 0.25, 17.

[0042] Optionally, the above step S103, pre-treating phase B with a cationic conditioning agent to obtain a treated phase B, can be implemented as follows:

[0043] Add sufficient production water in proportion to the production auxiliary pot, adjust the stirring speed to 5r / min, start stirring, sprinkle the 120E conditioner in phase B into the pot several times, continue stirring for 5-10min until the surface of 120E is completely wetted, pause stirring, put the remaining components of phase B into the auxiliary pot at one time, increase the speed to 10-12r / min, restart stirring, and gradually increase the temperature to 75-80℃, stir until the components are completely dissolved and evenly, and keep warm at not less than 65℃ for standby use.

[0044] In the embodiment of the present application, first add sufficient production water (cold water) in proportion to the production auxiliary pot, adjust the stirring speed to 5r / min, and start stirring. Sprinkle the 120E conditioner in phase B into the pot several times, and continue to stir for 5-10 minutes until the surface of 120E is completely wetted (no yellow solid mass at this time). Pause stirring, put the remaining components of phase B into the auxiliary pot at one time, increase the speed to 10-12r / min, restart stirring, and gradually increase the temperature to 75-80℃, stir until the components are completely dissolved and evenly dissolved, and keep warm at not less than 65℃ for standby use.

[0045] In the specific implementation, 120E should not be put in all at once, as it is easy to form large gel lumps, which will wrap part of 120E, making it difficult to wet and disperse, increasing the process time and difficulty. After phase B is completely dissolved, the temperature before being put into the main production pot must be kept above 65°C, otherwise it will cause the KDMP of phase B to precipitate. After KDMP precipitates, it is put into the main production pot. Due to the presence of anionic surfactants, it will be difficult for KDMP to dissolve.

[0046] S104, putting the pretreated B phase component into the main production pot, stirring at 75°C-80°C for 10-15 minutes until it is completely mixed, and starting to cool down.

[0047] In a specific implementation, the pretreated phase B component can be put into the main production pot, kept warm and stirred at 75°C-80°C for 10-15 minutes until it is completely mixed, and then the temperature can be lowered.

[0048] S105, pre-treating the C phase with Carbopol 980 to obtain a pre-treated C phase.

[0049] In the embodiment of the present application, the C phase can be pretreated with Carbopol 980 to obtain a pretreated C phase.

[0050] Optionally, the C phase includes: Carbopol 980 and water.

[0051] In the embodiment of the present application, Carbomer 980 may include Carbomer.

[0052] The ratio (%) of Carbopol 980 and water in phase C can be: 0.35, 15.

[0053] Optionally, the above step S105, performing Carbogen 980 pretreatment on the C phase to obtain the pretreated C phase, may include the following steps:

[0054] Use an auxiliary production container to disperse the Cabo 980 in 15 parts of 70-80°C hot water, use a stirrer to stir for 10-20 minutes at a stirring rate of 10-15 r / min to fully moisten the Cabo, start homogenization, adjust the speed to 1000-2000 r / min, and fully hydrate the Cabo 980 through high-speed shearing. At this time, the prefabricated liquid is a uniform translucent gel, which is left to stand for use.

[0055] In the embodiment of the present application, an auxiliary production container can be used to disperse Cabo 980 in 15 parts of 70-80°C hot water, and a stirrer is used to stir for 10-20 minutes at a stirring rate of 10-15 r / min to allow the Cabo to be fully moistened. At this time, the mixture is in the form of uneven semi-permeable gel particles without white clumps. Then the homogenizer is turned on and the speed is adjusted to 1000-2000 r / min. The Cabo 980 is completely hydrated through high-speed shearing. At this time, the prefabricated liquid is in a uniform translucent gel state and is left to stand for use.

[0056] In specific implementation, Carbopol 980 plays a role in suspension, stabilization and thickening in the system. It needs to be fully hydrated and swollen before being added to the main production pot, otherwise it will form transparent gel particles in the subsequent process and cannot be completely stirred and dispersed, thus affecting the viscosity, stability and uniform appearance of the product.

[0057] S106, putting the pretreated Carbopol 980 into the main production pot, maintaining stirring at a speed of 10-15 r / min, and starting homogenization, homogenizing at a shear rate of 1000-1500 r / min for 3-5 minutes to fully mix the material.

[0058] In the embodiment of the present application, the pretreated Carbopol 980 can be put into the main production pot, stirred at a speed of 10-15 r / min, and homogenized for 3-5 minutes at a shear rate of 1000-1500 r / min to ensure that the material is fully mixed.

[0059] In the specific implementation, since the pH value of the material in the main production pot is above 6.5, after the addition of Carbopol 980, it will be partially neutralized and form a transparent gel material, so properly starting the homogenization is conducive to the dispersion of Carbopol 980. However, the shear rate should be controlled at 1000-1500r / min, and should not be too large, otherwise it will cause the chain of Carbopol 980 to break and affect the stability of the product.

[0060] S107. When the temperature in the main production pot drops to 45-50°C, add the components of phase D into the main production pot, keep stirring at a rate of 10-15r / min for 10-15min, and homogenize at a shear rate of 1000-1500r / min for 1-2min to ensure that the components can be fully mixed.

[0061] In the embodiment of the present application, when the temperature in the main production pot drops to 45-50°C, the components of phase D are put into the main production pot, stirred at a rate of 10-15r / min for 10-15min, and homogenized at a shear rate of 1000-1500r / min for 1-2min, so that the components can be fully mixed.

[0062] In specific implementation, starting the homogenization again is beneficial for the oil components to be emulsified by the surfactant solution and dispersed more evenly in the system, which helps to improve stability.

[0063] Optionally, the D phase includes: HE, Silsoft Silk, EP 6205 and SF3000C.

[0064] In the embodiment of the present application, HE may include PEG-7 glyceryl cocoate. Silsoft Silk may include: polysilicone quaternium salt-18, trideceth-6, deceth-7, cocamidopropyl betaine, dipropylene glycol. EP 6205 may include: PPG-5 ceteth-20. SF3000C may include: ethylene glycol distearate, water, laureth-4, cocamidopropyl betaine, benzoic acid.

[0065] The proportions (%) of Silsoft Silk, EP 6205 and SF3000C in phase D may be: 0.7, 0.5, 0.4, 2.

[0066] S108. When the temperature drops below 40°C, add the E phase components and stir at a rate of 10-15 r / min for 20-30 min to completely dissolve the E phase components.

[0067] In the embodiment of the present application, when the temperature drops below 40° C., the E phase components are added and stirred at a rate of 10-15 r / min for 20-30 min to completely dissolve the E phase components.

[0068] Optionally, the E phase includes: OCT.

[0069] In the embodiment of the present application, OCT may include: piroctone olamine salt.

[0070] Wherein, the proportion (%) of OCT in the whole formula may be: 0.3.

[0071] Among them, the E phase includes OCT. The E phase OCT is an anti-dandruff agent. High temperature will promote its complexation with iron ions, causing the material to turn yellow. Therefore, in order to control the yellow color of the material, it is advisable to add the E phase components within 40°C, and at the same time control the introduction of iron ions by raw materials and production tools.

[0072] Among them, since E-phase OCT is an anti-dandruff agent, it can enhance the anti-dandruff and anti-itching effects.

[0073] S109, putting the components of phase F into the main production pot, stirring at a rate of 10-15r / min for 10-15min to ensure that the components are mixed and dispersed evenly.

[0074] In the embodiment of the present application, the components of phase F can be put into the main production pot and stirred at a rate of 10-15r / min for 10-15min to ensure that the components are evenly mixed and dispersed.

[0075] Optionally, the F phase includes: Scalpvitin, Antimicro C230, Snowland Ganoderma lucidum fermentation filtrate Filtrate-DGL, DX-701, essence, and NaCl.

[0076] In the embodiment of the present application, Scalpvitin may include: saccharide isomers, water, citric acid, sodium citrate. Antimicro C230 may include: phenoxyethanol, benzyl alcohol, benzoic acid. Snowland Ganoderma lucidum fermentation filtrate Filtrate-DGL may include: bifid yeast fermentation product filtrate, black Ganoderma lucidum extract, 1,2-hexanediol, and p-hydroxyacetophenone. DX-701 may include yeast / rice fermentation product filtrate.

[0077] Wherein, the proportions (%) of calpvitin, Antimicro C230, snow-covered Ganoderma lucidum fermentation filtrate Filtrate-DGL, DX-701, essence and NaCl in phase F can be: 0.3, 0.6, 2, 0.2, 0.7 and 0.6.

[0078] S110, adding the G phase component into the main production pot, reducing the rotation speed to 5-10 r / min, continuing stirring for 20-30 min, filtering the material, and obtaining the anti-dandruff and antipruritic composition.

[0079] In the embodiment of the present application, the G phase component is put into the main production pot, the rotation speed is reduced to 5-10r / min, stirring is continued for 20-30min, and the material is filtered out.

[0080] Optionally, the G phase includes: KOH solution (10%), and the KOH solution includes potassium hydroxide and water.

[0081] Wherein, the proportion (%) of phase G in the whole formula can be: 0.5.

[0082] In specific implementation, phase G can be added for alkali neutralization, and the pH value of the system is 6-7, so that the network structure of Carbopol 980 can be further stretched and its suspension stability can be better exerted. At this time, the homogenization should not be started again, otherwise the network structure of Carbopol 980 that has been stretched will be broken, affecting the stability.

[0083] In the embodiments of the present application, the anti-dandruff and anti-itching composition has a white to slightly yellow viscous material appearance, a specific fragrance, and a pH value of 6-7.

[0084] In the embodiment of the present application, the preparation method of the anti-dandruff and antipruritic composition may include the following steps:

[0085] 1. Put all the components in phase A into the main production pot, adjust the speed to 10-12r / min, and start stirring.

[0086] 2. Connect the jacket in the main production pot to high-temperature steam, heat the temperature in the main production pot to 75-80℃, and keep it warm and stir until all components are evenly dissolved.

[0087] 3. Pretreatment of cationic conditioning agent: First add sufficient production water (cold water) in proportion to the production auxiliary pot, adjust the stirring speed to 5r / min, and start stirring. Sprinkle the 120E conditioning agent in phase B into the pot several times, and continue to stir for 5-10 minutes until the surface of 120E is completely wet (no yellow solid mass at this time). Pause stirring, put the remaining components of phase B into the auxiliary pot at one time, increase the speed to 10-12r / min, restart stirring, and gradually increase the temperature to 75-80℃, stir until the components are completely dissolved and evenly dissolved, and keep warm at no less than 65℃ for standby use.

[0088] 4. Add the pre-treated phase B component in step 3 into the main production pot, keep warm at 75℃-80℃ and stir for 10-15 minutes until it is completely mixed. Start cooling.

[0089] 5. Pretreatment of Carbopol 980 (Phase C): Use an auxiliary production container to disperse Carbopol 980 in 15 parts of 70-80℃ hot water, and use a stirrer to stir for 10-20 minutes at a stirring rate of 10-15r / min to fully wet the Carbopol. At this time, the mixture is in the form of uneven semi-permeable gel particles without white clumps. Then turn on the homogenizer and adjust the speed to 1000-2000r / min. The Carbopol 980 is fully hydrated through high-speed shearing. At this time, the prefabricated liquid is in the form of a uniform translucent gel and is left to stand for use.

[0090] 6. Put the Carbopol 980 pretreated in step 5 into the main production pot, keep stirring at a speed of 10-15r / min, and start homogenizing. Homogenize at a shear rate of 1000-1500r / min for 3-5min to fully mix the material.

[0091] 7. When the temperature in the main production pot drops to 45-50°C, add the components of phase D into the main production pot, keep stirring at a rate of 10-15r / min for 10-15min, and homogenize at a shear rate of 1000-1500r / min for 1-2min to ensure that the components can be fully mixed.

[0092] 8. Starting the homogenization again will help the oil components to be emulsified by the surfactant solution and dispersed more evenly in the system, which will help improve stability.

[0093] 9. When the temperature drops below 40°C, add the E phase components and stir at a rate of 10-15 r / min for 20-30 min to completely dissolve the E phase components.

[0094] 10. Add all components of phase F into the main production pot and stir at a rate of 10-15r / min for 10-15min to ensure that all components are mixed and dispersed evenly.

[0095] 11. Put the G phase component into the main production pot, lower the speed to 5-10r / min, continue stirring for 20-30min, and filter the material.

[0096] In the examples of the present application, the water used to prepare the anti-dandruff and antipruritic composition is treated as follows: using membrane separation technology to remove microorganisms, viruses, small molecular organic matter, heavy metals, inorganic salt ions and other impurities with high precision. Ensure that the production water meets the process requirements. The conductivity is ≤5μS / cm, and the pH value is in the range of 5.5-7.5.

[0097] In specific implementation, water is the ingredient with the highest proportion of addition in the product, and the quality of the production water directly affects the quality and safety of the product. Therefore, the purification of production water to remove most of the insoluble impurities, metal ions, inorganic salt ions and microorganisms is a key control point for product quality and safety. In the embodiment of the present application, by removing most of the insoluble impurities, metal ions, inorganic salt ions and microorganisms, the quality of water is guaranteed, which can further improve the anti-dandruff and antipruritic effect.

[0098] In the embodiment of the present application, the design requirements for water are as follows: raw water supply ≥ 6T / H, water pressure 2.0kg / cm 2 , water temperature: 15-30℃, raw water quality (tap water) conductivity <350us / cm.

[0099] In the specific implementation, the following Figure 2 The system process in which the water for producing the anti-dandruff and antipruritic composition is prepared is, specifically, raw water tank -> raw water pump -> fully automatic sand filter -> fully automatic carbon filter -> fully automatic water softener -> precision filter -> primary desalination equipment -> ultraviolet sterilizer -> sterile pure water tank -> ultraviolet sterilizer -> ozone generator -> circulating water supply pump -> water use point.

[0100] Among them, the fully automatic water softener adopts a softening water salt tank, and the precision filter adopts an antiscalant medicine box.

[0101] The working principle of the raw water tank is to regulate the water quality and quantity of the system's water supply, prevent the instability of the water supply quantity and water quality from affecting production, and play a certain role in settling impurities in the incoming water. High and low water level control devices are set in the raw water tank, and high and low water level alarm indications can be displayed in the control system.

[0102] The raw water pump is the raw water booster pump, and its working principle is to provide the power source for the normal operation of the pretreatment system. The pump is equipped with a high overheat protector and a pressure controller, and automatically alarms when a fault occurs, and is interlocked with the raw water tank liquid level to achieve automatic operation and stop when full or empty.

[0103] Among them, the working principle of the fully automatic sand filter: the sand filter is the first step of pretreatment, mainly used to remove colloidal substances, suspended solid particles, silt, some macromolecular organic matter and microorganisms. The use of quartz sand and manganese sand filter materials has a good removal effect through filtration and retention. High filtration accuracy: the removal rate of suspended matter in water is close to 100%; prevent colloids and suspended solid particles, silt, etc. from causing blockage; prevent macromolecular organic matter and microorganisms from causing pollution blockage.

[0104] Among them, the working principle of the fully automatic carbon filter: activated carbon is made of raw materials such as wood, coal, coconut shells or petroleum residues. After dehydration and carbonization, the non-carbon components in the raw materials are removed to form a porous carbonized material. Due to the differences in raw materials and manufacturing methods, as well as the differences in activation temperatures, the adsorption of the activated carbon produced is also different. The activated carbon adsorption method is to remove water-soluble or difficult-to-separate organic matter contained in water by adsorption of activated carbon. As a water treatment unit, its treatment purpose includes removing BOD and COD decolorization in water. Generally, it is often used as a secondary treatment after the biological treatment unit to remove pollutants such as organic matter that cannot be decomposed during the biological treatment process. In the application of water treatment, it is mainly used to reduce residual chlorine or other oxidants such as ozone in water. Its adsorption effect is also very effective in reducing the silt index (SDI).

[0105] Among them, the working principle of the fully automatic water softener: the softener is one of the important pretreatment devices of the reverse osmosis system. Because the raw water contains cations such as Ca2+ and Mg2+, the compounds formed by them, such as Ca(OH)2 and Mg(OH)2, are the fundamental reason for the hardness of water, and are also one of the important reasons for the fouling of reverse osmosis membrane elements. The filler of the softener is a strong acid cation exchange resin, which can exchange cations such as Ca2+ and Mg2+ in the raw water, making it difficult to generate insoluble substances, thereby reducing the hardness of the raw water, ensuring the normal operation of the reverse osmosis membrane element, reducing the number of cleanings, and effectively prolonging the service life of the membrane element.

[0106] The antiscalant dosing device may include: a dosing pump, a medicine, and installation accessories. The antiscalant dosing device may include an antiscalant medicine box.

[0107] Among them, the working principle of the scale inhibitor dosing device: the negatively charged molecular chain in the reverse osmosis scale inhibitor forms a water-soluble complex or chelate with Ca2+, thereby increasing the solubility of inorganic salts and playing a scale inhibition role; some functional groups in the reverse osmosis scale inhibitor molecules occupy a certain position on the inorganic salt crystal nucleus or microcrystal, hindering and destroying the normal growth of inorganic salt crystals, slowing down the growth rate of crystals, and thus reducing the formation of salt scale. Dosing pump: constant flow manual adjustment or automatic adjustment, flow ratio adjustment according to external analog signal or digital pulse, four pulse signal inputs can be selected. Agent: scale inhibitor CP\ROBYJ886. Installation accessories: SUS316 / electrical components / pressure gauge.

[0108] The working principle of the precision filter is to prevent the membrane element from being damaged by solid particles during operation and to intercept impurities with a particle diameter greater than 5Em. Such particles may penetrate the reverse osmosis membrane assembly after being pressurized by a high-pressure pump, causing a large amount of salt leakage and may scratch the impeller of the high-pressure pump.

[0109] Among them, the primary desalination equipment can include: reverse osmosis desalination equipment. The working principle of the reverse osmosis desalination equipment is: according to the reverse osmosis principle, it uses the property of the reverse osmosis membrane that can only selectively pass through the solvent (usually water) and intercept ionic substances, and uses the static pressure difference on both sides of the membrane as the driving force to overcome the osmotic pressure of the solvent, so that the solvent passes through the reverse osmosis membrane to achieve the membrane separation process of separating the liquid mixture. The membrane separation method can remove harmful substances such as particles, colloids, organic impurities, microorganisms and 99.0% of dissolved salts in the water to achieve the purpose of water desalination and purification. Compared with the traditional ion exchange and distillation technology for pure water, the reverse osmosis technology has the advantages of small equipment size, low energy consumption, strong adaptability, no acid and alkali regeneration agent, simple process, easy to realize automation, excellent water quality, stable water quality, no microorganisms, no heavy metal ions, no organic compounds, etc. It is a separation technology that meets environmental protection requirements. There is no need to consider the stability of the inlet water quality too much. The water quality of the reverse osmosis system can remain stable for a long time without consuming any regenerated substances. This is one of its most important characteristics.

[0110] Among them, the working principle of the ultraviolet sterilizer: the water treatment ultraviolet sterilizer can effectively and quickly sterilize water without heating and using harmful chemicals. The treated water has no odor. It uses the 254mm ultraviolet lamp tube with bactericidal effect to radiate and quickly and reliably destroy bacteria, viruses and other microorganisms in the water.

[0111] The working principle of the sterile pure water tank is to regulate the water supply of the system to prevent the instability of water supply quantity and water quality from affecting production. High and low water level control devices are set in the pure water tank, which can display high and low water level alarm indications in the control system.

[0112] Among them, the working principle of the ozone generator: Ozone is a widely recognized and highly effective bactericidal disinfectant. Ozone is produced by high-frequency and high-voltage discharge using air or oxygen as raw materials. Ozone has one more active oxygen atom than oxygen molecules. Its chemical properties are particularly active. It is a strong oxidant that can quickly kill bacteria in water and air at a certain concentration. There is no toxic residue and no secondary pollution. It is known as the cleanest oxidant and disinfectant.
