Description
Technical Field
The application relates to the field of daily cosmetics, in particular to a preparation method of short-rheology amino acid composite cleaning system bath mud.
Background
In recent years, along with the improvement of daily life of people, the bath lotion gradually replaces perfumed soap, and because the bath lotion is more convenient and safer to use, a user can select to use the bath lotion product when bathing and cooling. Previously, the shower gel products commonly seen in the market generally only have the effects of washing and sterilizing, but at present, the requirements of people on the use comfort of the shower gel are higher and higher, and the requirements of formula engineers are also higher and higher: has rich foam, good cleaning ability, high mildness and refreshing skin feel after bathing. At present, in the technical aspect of bath lotion formulation, the main formulation system of the bath lotion mainly has two types, and the two types of bath lotions have the defects that the first type is surface active agent type bath lotion which is formed by compounding main surface active agents, namely anionic surface active agents represented by sulfate, such as lauryl alcohol ether sulfate, lauryl alcohol sulfate and the like, and other acceptable components, and has the defects of strong residual feeling after bathing and tight after washing; the second type is a saponification type bath cream which is formed by saponifying a soap base formed by fatty acid and potassium hydroxide or sodium hydroxide and compounding other acceptable components; the saponification type bath cream is easy to form soap blocks in the saponification reaction process, the soap blocks are formed to influence the solubility of fatty acid salt in water, polyhydric alcohol is added into a soap base system in the prior bath cream, experimental researches show that the addition of glycerol increases the viscosity value of the soap base system at zero shear rate, the glycerol increases the yield value of the soap base system, the glycerol increases the shear stability of the soap base system and the shearing resistance is increased, because the glycerol is added into the soap base system, the property of a solvent can be changed, the hydrogen bonding effect between the solvent and fatty acid salt molecules is enhanced, the macroscopic expression system viscosity is increased, and besides, the addition of alcohols such as glycerol increases the micelle phase range of the system, and the stability of the soap base system can be increased. However, if the formation of soap blocks is avoided through the dispersion effect of alcohol, excessive alcohol substances are needed to be added, and the skin is stimulated by the increase of the amount of the alcohol, so that the foamability of the shower gel is reduced; furthermore, the soap-based body wash has the problem that the formula system is difficult to thicken, and the skin has a tight feel after bathing.
On the other hand, on the texture of body washes, most of the body washes are medium-long-rheology liquids with certain viscosity or foam formulations without viscosity on the market, and the homogeneity is serious.
Disclosure of Invention
The present application aims to solve at least one of the technical problems existing in the prior art. Therefore, the application provides a preparation method of the bath mud with the short-rheology amino acid composite cleaning system.
The technical scheme adopted by the embodiment of the application for solving the technical problems is as follows:
a preparation method of bath mud with a short-rheology amino acid composite cleaning system comprises the following steps:
s1: preparing phase A, dispersing carbomer U21 in water, stirring and shearing until the carbomer U21 is in a non-uniform semi-transparent gel particle shape and no agglomerate is generated, homogenizing until the carbomer U21 is hydrated into a uniform semi-transparent gel shape, and cooling for later use;
s2: preparing phase B, namely adding coconut oil and palm oil into the stirring pot A, and heating to 80-85 ℃; adding water and potassium hydroxide into the stirring pot B, stirring until the water and potassium hydroxide are uniformly dissolved, and heating to 80-85 ℃; adding the solution uniformly dissolved in the stirring pot B into the stirring pot A, stirring at 80-85 ℃ until the solution becomes colorless to pale yellow transparent liquid, regulating the pH to 10-10.5, and cooling for later use;
s3: preparing a phase C, namely adding EDTA disodium, allantoin, glycerol, sodium cocoyl glutamate, sodium laureth sulfate, sodium methyl cocoyl taurate, sodium lauroyl sarcosinate, decyl glucoside and disodium cocoyl amphodiacetate into a phase C stirring pot for stirring uniformly, and adding the phase B into the phase C stirring pot for stirring uniformly under the condition of vacuumizing;
s4: preparing phase D, namely dividing aminomethyl propanol into two parts, uniformly mixing and stirring one part of the aminomethyl propanol with phase A to enable the phase A to be in a half-neutral state, then adding phase A into phase C to uniformly stir, then adding the other part of aminomethyl propanol, and uniformly stirring at the speed of 10 r/min;
s5: preparing phase E, namely uniformly stirring zinc pyrithione, bentonite, sea mud and water, and then adding the mixture into a stirring pot C for uniform stirring; adding water, saccharide isomer, citric acid, sodium citrate, water, polyquaternium-22 and sodium benzoate, and stirring uniformly; adjusting the pH to 7.5-8; stopping stirring, vacuumizing, and discharging after the index of the material body is checked to be qualified.
Preferably, in S1, the shear rate for the U21 wave is between 1000 and 2000r/min.
Preferably, in S1, the stirring temperature of the carbopol U21 is controlled to be 65-70 ℃.
Preferably, in S3, the time of vacuumizing is 3-5min, and the stirring speed is 3-5r/min.

Table 1 example of formulation of example 1
The total mass of the raw material components is 100g.
The preparation method comprises the following steps:
step one: preparation of phase A
Pretreatment of the carbomer U21 (phase a): dispersing the carbomer U21 in 35-50g of water, heating to 65-70 ℃, maintaining the temperature and stirring for 20-30min to fully wet the carbomer U21, wherein the mixture of the carbomer U21 and the water presents uneven semi-permeable gel particles and has no white agglomerates. Then starting homogenizing, regulating the rotating speed to 1000-2000r/min, completely hydrating the carbowave U21 under the high-speed shearing action, and cooling the prefabricated liquid into uniform semitransparent gel;
step two: preparation of phase B
Adding palm oil into the stirring pot A, and heating to 80-85deg.C; adding water into the stirring pot B, adding potassium hydroxide, stirring to dissolve uniformly, and heating to 80-85 ℃. Adding the liquid of the stirring pot B into the stirring pot A, maintaining the temperature at 80-85 ℃ and stirring for 30-40min until the solution becomes colorless to pale yellow transparent liquid, and finally regulating the pH to 10-10.5. Cooling for standby;
step three: mixing the components of the phase C in a production pot of the phase C, starting stirring, regulating the rotating speed to 15-16r/min, and stirring until the materials are uniformly dissolved. Stopping stirring, adding the prefabricated B phase component in the second step into a pot according to the proportion of the formula, then starting stirring, reducing the stirring rotating speed to 3-5r/min, starting vacuumizing for 3-5min, and pumping out the generated foam in the stirring process.
Step four: and mixing half of the D-phase aminomethylpropanol with the prefabricated A-phase, manually stirring uniformly to enable the A-phase to be in a half-neutral state, then putting the A-phase into a C-pot, stirring for 10min at a stirring rate of 10r/min, then adding the rest D-phase, and stirring and uniformly mixing at a stirring rate of 10 r/min.
Step five: mixing the E phase components, manually stirring and dispersing, then putting into a C pot, and stirring at a stirring speed of 10r/min until the E phase components are uniformly dispersed; reducing the stirring speed to 3-5r/min, adding the F-phase components into the C pot item by item, then increasing the rotating speed to 10r/min, and keeping stirring for 30min until the materials are uniformly mixed; measuring the PH, controlling the final PH to 7.5-8, stopping stirring, starting vacuumizing for 10-15min, and accelerating defoaming; and (5) after physical and chemical indexes such as viscosity, appearance, smell and the like of the material are inspected to be qualified, discharging and standing, checking, and filling.
The design idea of the first step is as follows: 1. the wetting dispersion of the carbowave U21 can be accelerated by controlling the temperature between 65 and 70 ℃. The too low temperature can greatly prolong the process time, and the too high temperature increases the energy consumption, but the subsequent cooling time is prolonged by 2, and the hydration and dispersion of the carbomer U21 are accelerated by the shearing action, so that the process time is shortened. Meanwhile, if the carbomer U21 is not completely hydrated and swelled in the step, when the carbomer U21 is added into a solution containing a surfactant, transparent carbomer gel particles are easy to appear, and are not easy to disperse and dissolve in subsequent stirring, so that the stability of a formula is affected, and carbomer aggregates can be quickly dispersed at a shear rate of 1000-2000r/min, so that the rate of the carbomer hydration and swelling is increased. If the rotating speed is too high, more bubbles are introduced, and meanwhile, the carbody net structure is damaged to a certain extent.
The design idea of the second step is as follows: 1. the solution in A, B stirring pot needs to be heated to 80-85 ℃ respectively for mixing, otherwise, the temperature of the system is too low in the mixing process, soap blocks appear, and the preparation time is too long. 2. During the mixing of the ingredients of the two pans, the aqueous phase needs to be added into the oil phase rapidly for stirring in a heat-preserving manner, otherwise soap blocks are caused. 3. The stirring time is kept at 30-40min, and whether the material body is colorless to light yellow transparent state is visually confirmed. Otherwise, incomplete saponification can occur, which affects the quality of the product. 4. The potassium cocoate and the potassium palmitate are prefabricated materials, the potassium cocoate and the potassium palmitate are required to be prepared in advance for standby in the production process, the PH is regulated to 10-10.5, the stability of the materials can be effectively maintained, meanwhile, the propagation of microorganisms can be inhibited, and the longer preservation time can be achieved without adding any preservative.
The design idea of the third step: 1. the step can be performed by cold matching, so that the energy consumption in the production process is reduced. 2. When phase B is added, stirring should be stopped first to avoid generating a large amount of bubbles. 3. The evacuation process requires a lower rotational speed, which would otherwise lead to more bubbles. The low-speed stirring can increase the foam pumping efficiency, so that the foam at the lower layer of the pot can be more quickly broken. 4. The operation of vacuumizing is very critical, if a lot of bubbles remain in the third step, after the fifth step of wave adding, defoaming is difficult to be carried out, so that the judgment of the appearance and quality state of the material body is directly affected, and whether the actual filling quantity meets the regulation is also affected.
The design idea of the fourth step: 1. the carbomer of the A phase is in a half-neutral state, and firstly, the consistency of the A phase is not too high, so that the feeding efficiency is not influenced. Secondly, the A Xiang Kabo is in a semi-swelling state, the network structure of the A Xiang Kabo is expanded to a certain extent, and the A Xiang Kabo is not easy to agglomerate into transparent gel particles when encountering a surfactant solution, so that the A Xiang Kabo cannot be dispersed. And after the material is fed, the rest alkali is added to completely neutralize, so that the carbomer is completely swelled, the reticular structure is opened, and the suspension stabilization effect is provided. 2. The stirring rate in this step is not preferably too high, which may lead to the introduction of a large amount of bubbles, resulting in difficult elimination of the subsequent step.
The design idea of the fifth step: the E phase can be added after being dispersed by water in advance, otherwise, the E phase can easily cause uneven dispersion, rough surface of a material body and influence the stability of a system. When feeding, the stirring rotation speed needs to be regulated down, so that excessive bubbles are avoided. 1. The pH needs to be controlled in the range of 7.5-8, and too high pH results in dry skin feel after washing. The pH value lower than 7 can lead to the surface activation and crystallization of amino acid, unstable potassium cocoate and potassium palmitate, and rough material body, so that the foam performance, skin feel after washing and appearance of the material body of the product are obviously affected. 2. In the final stage, the stirring is stopped because the consistency and suspension force of the material are already up, and the stirring cannot be effectively defoamed when the stirring is started during the vacuum pumping.
TABLE 1 bath mud formulation stability experiment
The experimental results show that samples 1 numbered A, B, C in sequence from left to right in fig. 1 respectively correspond to the sample state of the samples 1 in the 3 rd month of the heat-resistant experiment at 45 ℃, B is the state of the samples 1 in the 3 months at normal temperature, and C is the sample state of the samples 1 in the 3 months of the cold-resistant experiment at 5 ℃; as is clear from the above table 1 and fig. 1, sample 1 (i.e., example 1 of the present application) has excellent stability without abnormal phenomenon in the centrifugal test, the heat-resistant test at 45 ℃, the cold-resistant test at 5 ℃ and the normal temperature test.
In fig. 2, samples 2 numbered A1, B1 and C1 arranged from left to right correspond to the sample state of sample 2 at 3 months of the heat resistance test at 45 ℃, B1 is the state of sample 2 at normal temperature for 3 months, and C1 is the sample state of sample 2 at the cold resistance test at 5 ℃ for 3 months; as can be seen from the above table 1 and fig. 2, in the heat resistance test at 45 ℃, sample 2 showed that the surface of the material became rough at week 2; and the surface of the material became rough at the 2 nd month in the room temperature experiment. It can be seen that the stability of the bath mud of sample 2 is not acceptable.
Sample 3 of numbers A2, B2 and C2 arranged in order from left to right in fig. 3 corresponds to the sample state of sample 3 at 1 week of the 45 ℃ heat resistance test, respectively, B2 is the state of sample 3 at normal temperature for 1 month, and C1 is the state of sample 3 at normal temperature for 2 months; as can be seen from table 1 and fig. 3, sample 3 shows delamination during the centrifugation test, and also shows delamination during the heat-resistant test at 45 ℃ and the normal temperature test, and sample 3 also shows discoloration due to the problem of precipitation caused by uneven dispersion of ZPT-48 and essence in the system. It can be seen that the stability of the bath mud of sample 3 is not acceptable.
The preparation method of the application does not need to add excessive alcohol raw material components to reduce the generation of soap blocks, reduces the irritation of skin and also reduces the generation of soap blocks. The reduction of soap blocks can increase the uniformity of other raw material components and improve the stability of the bath mud. The application provides a short-flow shower mud, which has the same natural appearance as mud and is placed in a container, and the state of pouring out the shower mud from the container is short-flow, so that a user can conveniently take out a material body, and the phenomenon of wiredrawing of the material body is prevented. The application provides a shower gel with a texture different from that of the homogenized shower gel in the market, and the texture with short rheology is closer to that of mud.
The application reduces the damage to the structure of the carbowave network by creatively optimizing the processing technology of the carbowave U21; creatively and practically uses the carbomer in the semi-swelling state to react with the surfactant to prevent agglomeration into transparent gel particles, so that the reticular structure of the carbomer U21 can be opened to provide the function of suspension stability, and the prepared bath mud has the advantages of non-stickiness, good foaming performance and good stability after washing through the ring-to-ring buckling of the process.
The application also tries to replace the parallel test of the U21 by the U20 and 940, and finds that when the U21 is adopted, the U940 is not compatible with the system, and the U21 cannot be thickened, and in addition, the U20 has layering stability. In an alternative test of the carbopol U20, it was found that when the amount of carbopol U20 added was increased, the bath mud became a lump of particularly high consistency, which was difficult to squeeze out and push away in the skin when poured into a container, and the body had a sticky feel. When the addition amount is reduced, the medium-long rheological property of the material body appears, and mud-like short rheological bathing mud cannot be made. According to the preparation method, the carbopol U21 is selected, the consistency is more gradually increased, the consistency is not greatly increased even in a wider adding amount, but the levitation force is increased along with the increasing of the adding amount of the carbopol U21, so that the consistency is easier to control, and the control difficulty of the production process is simplified.
While the present application has been described in detail with reference to the above embodiments, it will be apparent to those skilled in the art from this disclosure that various changes or modifications can be made therein without departing from the spirit and scope of the application as defined in the following claims. Accordingly, the detailed description of the disclosed embodiments is to be taken only by way of illustration and not by way of limitation, and the scope of protection is defined by the content of the claims.
