Description

Technical Field

[0001] The present invention relates to the technical field of cosmetics, and in particular to a mild oil-control mud film composition that can withstand antiseptic challenges and a preparation method thereof. Background Art

[0002] Mud mask composition, as a skin care product deeply loved by consumers, is used by applying the product evenly to the facial skin. It forms a firm film to absorb oil, dirt and excess cuticle on the skin surface, thereby achieving deep cleansing, pore purification and balanced regulation of oil secretion.

[0003] In the existing mud mask composition preparation technology, in order to give the mud mask composition good adsorption and formability, 10-30% of natural powder raw materials such as kaolin or volcanic mud are usually added. The above-mentioned natural powder raw materials can not only effectively absorb the oil and dirt on the skin surface, but also have skin care effects such as gentle exfoliation and soothing the skin due to their natural properties. However, the strong adsorption capacity of the above-mentioned natural powder raw materials causes them to not only absorb the oil and dirt on the skin surface, but also absorb most of the preservatives in cosmetics, resulting in a decrease in the overall antiseptic effect of cosmetics.

[0004] In order to overcome the above defects, the prior art generally adopts the following measures: (1) Introducing highly irritating and efficient fungicides such as methylisothiazolinone, methylisochlorothiazolinone, chlorphenesin, DMDM ​​hydantoin, etc. as preservatives. The above-mentioned efficient fungicides can be used alone or in combination to match the characteristics of different products. Although the strong adsorption capacity of natural powder raw materials can reduce the free concentration of highly irritating and efficient fungicides in water, the latter has the ability to quickly penetrate the cell membrane of microorganisms, which may cause greater irritation to the skin when used, affecting the mildness of the mud mask composition; in addition, the reduction in the free concentration of highly irritating and efficient fungicides in water also directly leads to a decrease in its antibacterial rate (i.e., the antiseptic effect). (2) Increasing the amount of preservative added. Given that preservatives themselves are usually highly irritating, this approach improves the antiseptic effect of the mud mask composition, but at the same time significantly increases the irritation to the skin, and also damages the mildness of the mud mask composition. Therefore, the above methods have failed to make the mud mask composition have excellent antiseptic properties while maintaining mildness.

[0005] Furthermore, although the oil absorption properties of the 10-30% natural powder raw materials added to the mud mask composition help achieve effective cleansing and oil control effects, they may also lead to over-cleansing, which in turn causes a series of skin problems such as dry skin, tightness, and even damage to the skin barrier. In addition, the oil control effect of natural powder is mainly based on a physical mechanism, that is, it absorbs oil on the skin surface through its microporous structure, thereby temporarily improving the appearance of oily skin. However, the above oil control method has the disadvantages of limited timeliness and the possibility of increased skin oil secretion after use.

[0006] Therefore, how to maintain the good cleaning and oil control effects of the mud mask composition while taking into account both mildness and high corrosion resistance has become a key problem that needs to be urgently solved in the current research and development of mud mask composition products. Summary of the invention

[0007] The first purpose of the present invention is to propose a mild oil-control mud film composition that can pass the anti-corrosion challenge. While maintaining the good cleaning and oil-control effects of the mud film composition, it also takes into account mildness and high anti-corrosion properties to overcome the shortcomings of the prior art.

[0008] The second purpose of the present invention is to propose a method for preparing a mild oil-control mud film composition that can withstand corrosion challenges. The preparation method is simple and easy to operate, which is conducive to ensuring that the mud film composition has good cleaning and oil-control effects while taking into account mildness and high corrosion resistance.

[0009] To achieve this object, the present invention adopts the following technical solutions:

[0010] A mild oil-control mud film composition that can withstand antiseptic challenges, calculated by mass percentage, includes 4.15-6.7% thickener, 15-22% moisturizer, 13-20% natural powder, 8-14.5% oil-soluble emollient, 2-4% emulsifier, 1-2% oil-control agent, 1.4-2% composite preservative and 46.05-53% water;

[0011] The composite preservative includes Corson K708 preservative and Corson K805 preservative.

[0012] Furthermore, calculated by mass ratio, the mixing ratio of the Corson K805 preservative and the Corson K708 preservative is 1:(1-1.2).

[0013] Furthermore, the natural powder includes kaolin and volcanic mud;

[0014] Calculated by mass ratio, the mixing ratio of the kaolin and the volcanic mud is (10-15): (3-5).

[0015] Furthermore, the oil control agent is zinc pyrrolidone carboxylate.

[0016] Further, the thickener includes distarch phosphate, bentonite and polyacrylate cross-linked polymer-6;

[0017] Calculated by mass ratio, the mixing ratio of the distarch phosphate, the bentonite and the polyacrylate cross-linked polymer 6 is (2-3): (2-3.5): (0.15-0.2).

[0018] Further, the oil-soluble emollient includes ethylhexyl palmitate and caprylic / capric triglyceride;

[0019] Calculated by mass ratio, the mixing ratio of the ethylhexyl palmitate and the caprylic / capric triglyceride is (3-5):(5-8).

[0020] Further, the emulsifier includes potassium cetyl phosphate, stearyl alcohol, dioctyldodecyl lauroyl glutamate and cetearyl alcohol;

[0021] Calculated by mass ratio, the mixing ratio of the potassium cetyl phosphate, the stearyl alcohol, the dioctyldodecyl lauroyl glutamate and the cetearyl alcohol is (6-15):1:1:(10-15).

[0022] Further, the moisturizing agent includes propylene glycol and glycerol;

[0023] Calculated by mass ratio, the mixing ratio of the propylene glycol and the glycerol is (10-15):(5-7).

[0024] Furthermore, it also includes metal chelating agents, skin allergy-reducing agents and skin repairing agents;

[0025] Calculated by mass percentage, the mild and highly antiseptic mud mask composition includes 4.15-6.7% thickener, 15-22% moisturizer, 13-20% natural powder, 8-14.5% oil-soluble emollient, 2-4% emulsifier, 1-2% oil control agent, 1.4-2% composite preservative, 0.05-0.10% metal chelator, 1-1.5% skin anti-allergic agent, 0.1-0.15% skin repair agent and 46.05-53% water.

[0026] A method for preparing a mild oil-controlling mud film composition that can withstand corrosion challenges, for preparing the mild and highly corrosion-resistant mud film composition, comprises the following steps:

[0027] A. Add the formulated amount of water, thickener, metal chelating agent, skin repair agent and moisturizer into a first stirring device at a temperature of 80 to 85° C., stir for 5 to 15 minutes, and then homogenize for 5 to 15 minutes to obtain a first mixture;

[0028] B. Add the formulated amount of natural powder to the first mixture, stir for 3 to 5 minutes, and then homogenize for 3 to 5 minutes to obtain a second mixture;

[0029] C. Add the formulated amount of oil-soluble emollient and emulsifier into a second stirring device at a temperature of 80 to 85° C. and stir for 5 to 15 minutes, and then homogenize for 5 to 15 minutes to obtain a third mixture;

[0030] D. pumping the third mixture into the second mixture and stirring at 80-85° C. for 5-15 min, homogenizing for 5-15 min, and evacuating to obtain a fourth mixture;

[0031] E. Cool the fourth mixture to 45-50° C., add the formulated amount of oil control agent, skin anti-allergic agent and composite preservative to the cooled fourth mixture in sequence, stir for 5-15 minutes, and then homogenize for 5-15 minutes to obtain a mild and highly antiseptic mud mask composition.

[0032] The technical solution provided by the present invention may include the following beneficial effects:

[0033] 1. In the mud film composition, after the Corson K805 preservative is adsorbed by the natural powder, it loses its penetration into the bacterial cell membrane, but it can still effectively penetrate the fungal cell membrane to achieve a fungal killing effect. In addition, the Corson K708 preservative can avoid being adsorbed by the natural powder and is slowly released in the water. The bacterial cell membrane and some fungal cell membranes show good penetration, effectively killing bacteria and some fungi. Therefore, by combining the fungicidal ability of the Corson K805 preservative with the bacterial killing ability of the Corson K708 preservative, the composite preservative in this technical solution exhibits excellent broad-spectrum bactericidal properties, effectively inhibiting the reproduction of microorganisms in the mud film composition, and ensuring an excellent antiseptic effect.

[0034] 2. Compared with traditional highly irritating and highly effective fungicides (such as methylisothiazolinone, methylisochlorothiazolinone, chlorphenesin and DMDM ​​hydantoin, etc.), the irritation of K708 preservative and K805 preservative is relatively low, making the composite preservative less irritating. The low irritation property of the composite preservative and its high antiseptic ability cooperate with each other, making the mud mask composition both mild and highly antiseptic.

[0035] 3. In order to significantly improve the oil control timeliness of the mud mask composition, the present technical solution specifically adds an oil control agent to the mud mask composition. Among them, 5α-reductase plays a key role in sebum synthesis, and it is involved in the conversion of testosterone to dihydrotestosterone, which promotes the oil secretion of the sebaceous glands. The oil control agent can inhibit the activity of 5α-reductase, thereby slowing down the synthesis rate of sebum and achieving a significant oil control effect. Therefore, the present technical solution ensures the cleansing and oil control effects by utilizing the mutual cooperation of natural powders and oil control agents. DETAILED DESCRIPTION

[0036] The technical solution provides a mild oil-control mud film composition that can withstand antiseptic challenges, which includes, by mass percentage, 4.15-6.7% thickener, 15-22% moisturizer, 13-20% natural powder, 8-14.5% oil-soluble emollient, 2-4% emulsifier, 1-2% oil-control agent, 1.4-2% composite preservative and 46.05-53% water;

[0037] The composite preservative includes Corson K708 preservative and Corson K805 preservative.

[0038] In order to solve the technical problems in the prior art that the oil control effect of mud mask compositions is limited and it is difficult to take into account both mildness and high anti-corrosion, the present technical solution proposes a mild oil-control mud mask composition that can pass the anti-corrosion challenge, the raw materials of which include thickeners, moisturizers, natural powders, oil-soluble emollients, emulsifiers, oil-control agents, composite preservatives and water; preservatives include Kosen K708 preservative and Kosen K805 preservative.

[0039] Specifically, the prior art attempts to improve the antiseptic effect of the mud film composition by introducing highly irritating and efficient fungicides such as methylisothiazolinone, methylisochlorothiazolinone, chlorphenesin, DMDM ​​hydantoin, etc. as preservatives or increasing the amount of preservatives added, but the above methods fail to make the mud film composition have excellent antiseptic properties while maintaining mildness. Therefore, the present technical solution cannot be designed based on the above principle.

[0040] In order to make the mud mask composition both mild and highly antiseptic, the composite preservative composed of Kerson K708 preservative and Kerson K805 preservative is specially added to the mud mask composition formula in this technical solution. Among them, K708 preservative and Kerson K805 preservative are both preservatives produced by Kerson New Materials Technology (Guangzhou) Co., Ltd.; calculated by mass percentage, Kerson K805 preservative includes 10-15% methylparaben, 1-3% 1,2-hexanediol, 1-3% ethylhexylglycerol, 15-25% glycerol and 54-73% phenoxyethanol. In the mud mask composition, after being adsorbed by natural powder, Kerson K805 preservative loses its ability to penetrate bacterial cell membranes, but it can still effectively penetrate fungal cell membranes to achieve fungal killing effects. In addition, as a metallic silver preservative, the K708 preservative of Corson includes 10-20% colloidal silver and 80-90% water, calculated by mass percentage. Unlike the K805 preservative of Corson, the K708 preservative of Corson can avoid being adsorbed by natural powders and is slowly released in water. The bacterial cell membranes and some fungal cell membranes show good permeability, effectively killing bacteria and some fungi. Therefore, by combining the fungicidal ability of the K805 preservative with the bacterial killing ability of the K708 preservative, the composite preservative in the present technical solution shows excellent broad-spectrum bactericidal properties, effectively inhibiting the reproduction of microorganisms in the mud film composition, and ensuring excellent antiseptic effects. In addition, the composite preservative has an excellent antiseptic effect, so that the addition amount of the composite preservative in the mud film composition is only 1.4-2% to meet the antiseptic requirements, significantly reducing the irritation problems that may be caused by the high-dose use of traditional preservatives. In addition, compared with traditional highly irritating and highly effective fungicides (such as methylisothiazolinone, methylisochlorothiazolinone, chlorphenesin and DMDM ​​hydantoin, etc.), the irritation of K708 preservative and K805 preservative is relatively low, making the composite preservative less irritating. The low irritation characteristics of the composite preservative and its high antiseptic ability cooperate with each other, making the mud mask composition both mild and highly antiseptic.

[0041] Secondly, the raw materials of the mud mask composition also include natural powders, which absorb excess oil on the skin surface, dirt deep in the pores, and makeup residues through their microporous structure, thereby achieving a deep cleansing effect. However, the oil control effect of natural powders mainly relies on physical mechanisms, so its oil control timeliness is limited, and the skin's oil secretion may rebound after use, limiting the oil control performance of the mud mask composition.

[0042] In order to significantly improve the oil control timeliness of the mud mask composition, the present technical solution specifically adds an oil control agent to the mud mask composition. Among them, 5α-reductase plays a key role in sebum synthesis, and it is involved in the conversion of testosterone to dihydrotestosterone, which promotes the oil secretion of the sebaceous glands. The oil control agent can inhibit the activity of 5α-reductase, thereby slowing down the synthesis rate of sebum and achieving a significant oil control effect. Therefore, the present technical solution ensures the cleansing and oil control effects by utilizing the mutual cooperation of natural powders and oil control agents.

[0043] Again, the mud mask composition also includes a thickener, an oil-soluble emollient and an emulsifier. Among them, the thickener can not only increase the viscosity of the mud mask composition, so that it can better adhere to the skin surface, prevent the mud mask composition from dripping during use, and ensure the use effect, but the thickener is also helpful to prevent the natural powder from settling, thereby improving the stability of the mud mask composition. In addition, the technical solution limits the addition amount of the thickener to 4.15-6.7%, which is conducive to making the texture of the mud mask composition delicate and uniform, with a texture similar to ice cream, and improving the watery and smooth feeling when applied.

[0044] Furthermore, the oil-soluble emollient has a lubricating and protective effect, which minimizes abrasions, ensures the moisturizing degree of the mud film composition, and avoids the mud film composition being too dry and too strong in cleaning power during use, thereby causing dry skin, thereby improving the watery and smooth feeling of the mud film composition when applied. The emulsifier is conducive to the oil-soluble emollient being integrated into the water to form an emulsified system, ensuring the moisturizing effect of the oil-soluble emollient. That is, the technical solution ensures the skin feel of the mud film composition through the mutual cooperation of the thickener, the oil-soluble emollient and the emulsifier.

[0045] It should be noted that flavors may also be added to the mud mask composition according to actual needs to meet actual usage requirements.

[0046] It is further explained that, calculated by mass ratio, the mixing ratio of the Corson K805 preservative and the Corson K708 preservative is 1:(1-1.2).

[0047] Since the K708 preservative can not only effectively kill bacteria, but also some fungi; in addition, the irritation of the K708 preservative is lower than that of the K805 preservative. Therefore, the amount of the K708 preservative added in this technical solution is slightly higher than that of the K805 preservative, which is beneficial to improve the antiseptic performance and mildness of the mud film composition.

[0048] It is further stated that the natural powder includes kaolin and volcanic mud;

[0049] Calculated by mass ratio, the mixing ratio of the kaolin and the volcanic mud is (10-15): (3-5).

[0050] The high adsorption and chemical stability of kaolin, combined with the rich minerals and unique pore structure of volcanic mud, make the natural powder more effective in deep cleansing, nourishing the skin and balancing oil.

[0051] In addition, kaolin and volcanic mud are both cost-effective raw materials. By reasonably controlling the mixing ratio of kaolin and volcanic mud, the production cost can be effectively reduced while ensuring the performance of the mud film composition.

[0052] It is further described that the oil control agent is zinc pyrrolidone carboxylate.

[0053] Zinc pyrrolidone carboxylate can not only inhibit the activity of 5α-reductase, thereby slowing down the synthesis of sebum and achieving the effect of oil control, but also has anti-inflammatory and antibacterial properties, which is helpful in reducing the formation of acne and blackheads, and further improving the condition of oily skin. In addition, zinc pyrrolidone carboxylate is also mild and non-irritating to the skin, and has no side effects, which is helpful in improving the mildness of the mud mask composition.

[0054] It is further described that the thickener includes distarch phosphate, bentonite and polyacrylate cross-linked polymer ~6;

[0055] Calculated by mass ratio, the mixing ratio of the distarch phosphate, the bentonite and the polyacrylate cross-linked polymer 6 is (2-3): (2-3.5): (0.15-0.2).

[0056] Distarch phosphate has good thickening, stabilizing and bonding properties; bentonite has excellent water absorption, swelling and dispersion properties, which can enhance the viscosity and stability of the system; polyacrylate cross-linked polymer-6 has a stable three-dimensional structure, which can increase the viscosity and stability of the system. Therefore, the technical solution adopts the above three thickeners for mixing and limits the mixing ratio, which is conducive to preventing the sedimentation of natural powders, thereby improving the stability of the mud film composition. In addition, distarch phosphate and bentonite can increase the viscosity and smoothness, which is conducive to improving the ice cream texture of the mud film composition.

[0057] It is further described that the oil-soluble emollients include ethylhexyl palmitate and caprylic / capric triglyceride;

[0058] Calculated by mass ratio, the mixing ratio of the ethylhexyl palmitate and the caprylic / capric triglyceride is (3-5):(5-8).

[0059] Ethylhexyl palmitate has excellent moisturizing and softening effects, and caprylic / capric triglyceride has excellent emulsification, solubility, extensibility and lubricity. Therefore, in the technical solution, ethylhexyl palmitate and caprylic / capric triglyceride are mixed to form an oil-soluble emollient, which is conducive to ensuring the performance of the oil-soluble emollient, so that the mud mask composition can more effectively moisturize, soften and protect the skin and improve the skin feel. It should be noted that caprylic / capric triglyceride is a single component, not a mixture.

[0060] It is further described that the emulsifier includes potassium cetyl phosphate, stearyl alcohol, dioctyldodecyl lauroyl glutamate and cetearyl alcohol;

[0061] Calculated by mass ratio, the mixing ratio of the potassium cetyl phosphate, the stearyl alcohol, the dioctyldodecyl lauroyl glutamate and the cetearyl alcohol is (6-15):1:1:(10-15).

[0062] Potassium cetyl phosphate, stearyl alcohol, dioctyldodecyl lauroyl glutamate and cetearyl alcohol all have good emulsifying effects. The emulsifier formed by the cooperation of the above ingredients is conducive to ensuring that the emulsifier forms a stable film at the oil-water interface, thereby effectively preventing the aggregation and stratification of oil droplets or water droplets, and improving the stability of the mud film composition. In addition, potassium cetyl phosphate, stearyl alcohol, dioctyldodecyl lauroyl glutamate and cetearyl alcohol all have good skin compatibility, which can give the mud film composition a soft and delicate touch and reduce greasy feeling. In addition, cetearyl alcohol and dioctyldodecyl lauroyl glutamate have the effect of moisturizing and nourishing the skin, can enhance the barrier function of the skin, reduce water loss, and improve the moisturizing effect of the mud film composition.

[0063] It is further described that the moisturizing agent includes propylene glycol and glycerol;

[0064] Calculated by mass ratio, the mixing ratio of the propylene glycol and the glycerol is (10-15):(5-7).

[0065] Both propylene glycol and glycerol have moisturizing functions. Both can absorb and lock moisture on the skin surface, reduce the evaporation of moisture, and thus keep the skin moist. In addition, propylene glycol has good permeability and can bring moisture into the deep layer of the skin. Glycerol has a strong moisturizing ability and can absorb more moisture. Therefore, the technical solution uses propylene glycol and glycerol to mix to obtain a moisturizer, and limits the mixing ratio of propylene glycol and glycerol, which is conducive to ensuring the performance of the moisturizer.

[0066] Further description, it also includes metal chelating agents, skin anti-allergic agents and skin repair agents;

[0067] Calculated by mass percentage, the mild and highly antiseptic mud mask composition includes 4.15-6.7% thickener, 15-22% moisturizer, 13-20% natural powder, 8-14.5% oil-soluble emollient, 2-4% emulsifier, 1-2% oil control agent, 1.4-2% composite preservative, 0.05-0.10% metal chelator, 1-1.5% skin anti-allergic agent, 0.1-0.15% skin repair agent and 46.05-53% water.

[0068] Metal chelators can effectively chelate most metal ions in water and play an auxiliary role in corrosion prevention. In addition, skin anti-allergic agents can reduce or prevent skin irritation or allergies. Adding skin anti-allergic agents to mud mask compositions can reduce allergic reactions such as skin redness, swelling, itching, etc. that may be caused when using the mud mask compositions, and improve the mildness and safety of the products.

[0069] Furthermore, the skin repair agent can repair the damaged skin barrier, promote the regeneration and renewal of skin cells, and thus improve the skin condition. Adding the skin repair agent to the mud mask composition helps to enhance the skin's resistance and make the skin healthier, smoother and more elastic.

[0070] Preferably, the metal chelating agent is disodium ethylenediaminetetraacetate; the skin anti-allergic agent is 1609 is a skin care raw material produced in Germany. It is composed of 4-tert-butyl cyclohexanol and 1,2-pentanediol. It can resist excessive nerve activation, relieve excessive skin reaction, and thus reduce the occurrence of sensitive symptoms.

[0071] In addition, the skin repair agent is allantoin, which has physiological functions such as promoting cell growth, accelerating wound healing, and softening keratin, thereby playing a role in repairing the skin.

[0072] A method for preparing a mild oil-controlling mud film composition that can withstand corrosion challenges, for preparing the mild and highly corrosion-resistant mud film composition, comprises the following steps:

[0073] A. Add the formulated amount of water, thickener, metal chelating agent, skin repair agent and moisturizer into a first stirring device at a temperature of 80 to 85° C., stir for 5 to 15 minutes, and then homogenize for 5 to 15 minutes to obtain a first mixture;

[0074] B. Add the formulated amount of natural powder to the first mixture, stir for 3 to 5 minutes, and then homogenize for 3 to 5 minutes to obtain a second mixture;

[0075] C. Add the formulated amount of oil-soluble emollient and emulsifier into a second stirring device at a temperature of 80 to 85° C. and stir for 5 to 15 minutes, and then homogenize for 5 to 15 minutes to obtain a third mixture;

[0076] D. pumping the third mixture into the second mixture and stirring at 80-85° C. for 5-15 min, homogenizing for 5-15 min, and evacuating to obtain a fourth mixture;

[0077] E. Cool the fourth mixture to 45-50° C., add the formulated amount of oil control agent, skin anti-allergic agent and composite preservative to the cooled fourth mixture in sequence, stir for 5-15 minutes, and then homogenize for 5-15 minutes to obtain a mild and highly antiseptic mud mask composition.

[0078] The technical solution also proposes a method for preparing a mild oil-control mud film composition that can withstand corrosion challenges. The preparation method is simple and easy to operate, which is conducive to ensuring that the mud film composition has good cleaning and oil-control effects while taking into account mildness and high corrosion resistance.

[0079] Specifically, if the raw materials in step A and step B are added together, the dispersion time of the raw materials in step A will be too long, and the production efficiency will be reduced; in addition, the oil-soluble emollient and the emulsifier are both oil phases, so the two need to be mixed separately in the second stirring device to obtain a third mixture, and then pumped into the second mixture for mixing to obtain a fourth mixture. In addition, since the oil control agent, skin anti-allergic agent and composite preservative are low-temperature raw materials, the fourth mixture needs to be cooled to 45-50°C to avoid the temperature of the fourth mixture being too high, resulting in rapid degradation of the oil control agent, skin anti-allergic agent and composite preservative, and loss of their original efficacy.

[0080] It should be noted that homogenization refers to using the homogenizing blade at the bottom of the stirring equipment to break up the solid particles in the mixture to make them ultra-fine and form a uniform suspended emulsion.

[0081] The technical solution of the present invention is further illustrated below through specific implementation methods.

[0113] Comparative Example 2

[0114] The preparation method and raw materials of Comparative Example 2 are the same as those of Example 1, except that the composite preservative in Comparative Example 2 only includes the Kersen K805 preservative.

[0115] Comparative Example 3

[0116] Comparative Example 3 has the same preparation method and raw materials as Example 1, except that K609 preservative (composition includes methylisothiazolinone, phenoxyethanol and water) is used instead of composite preservative in Comparative Example 3. That is, calculated by mass percentage, the mild and highly preservative mud mask composition includes 5.65% thickener, 15% moisturizer, 18% natural powder, 8% oil-soluble emollient, 2.5% emulsifier, 2% oil control agent, 0.3% K609 preservative, 0.05% metal chelating agent, 1% skin anti-allergic agent, 0.1% skin repair agent and 47.40% water.

[0117] Comparative Example 4

[0121] A mud mask composition was prepared according to the preparation method in the embodiment and the comparative example, and the mildness, antiseptic property, stability, oil control effect and skin feel performance of the mud mask composition were tested. The specific test results are shown in Table 1 below:

[0122] Table 1 Performance test results of different mud film compositions in the examples and comparative examples

[0123] Performance test items Mildness Corrosion resistance stability Oil control effect Skin feel Example 1 Mild irritation pass qualified excellent excellent Example 2 Mild irritation pass qualified excellent excellent Example 3 Mild irritation pass qualified excellent excellent Comparative Example 1 Mild irritation Not passed qualified excellent excellent Comparative Example 2 Mild irritation Not passed qualified excellent excellent Comparative Example 3 Strong irritation Not passed qualified excellent excellent Comparative Example 4 Mild irritation pass qualified Difference excellent Comparative Example 5 Mild irritation pass Failure excellent Difference

[0124] From the performance test results of each embodiment in the above table, it can be seen that the mud mask composition prepared by the preparation method of the present technical solution is mild and non-irritating, has high antiseptic and stability, and has excellent oil control effect and skin feel performance. While maintaining the good cleansing and oil control effects of the mud mask composition, it also takes into account mildness and high antiseptic properties.

[0125] In Comparative Example 1, since the composite preservative only includes the Corson K708 preservative, and in Comparative Example 2, since the composite preservative only includes the Corson K805 preservative, the anti-corrosion performance of the mud film composition is reduced and the anti-corrosion property is unqualified.

[0126] In Comparative Example 3, since the highly irritating and efficient fungicide K609 was used as the preservative, the antiseptic property of the mud film composition decreased and the irritation increased.

[0127] In Comparative Example 4, since the oil-control agent zinc pyrrolidone carboxylate was not added, the oil-control effect of the mud mask composition was reduced and the oil-control effect was poor.

[0128] In Comparative Example 5, since no thickener was added, the stability and skin feel of the mud mask composition decreased, the stability was unqualified, and the skin feel was poor.
