Description

Technical Field

[0001] The present application relates to the field of soaps, and more specifically, to an amino acid surfactant mud salt double-sided multifunctional soap and a preparation method thereof. Background Art

[0002] Soap is an indispensable daily cleaning product. Ordinary soap is generally made of sodium fatty acid and other surfactants as the main raw materials, and is processed and formed after adding appearance improvers and quality improvers. Ordinary soap has strong cleaning power, alkaline pH value, hard soap body and easy to crack. In addition, the use of ordinary soap can easily damage the weak acid protective film of the skin, causing skin irritation, dryness and tightness after use, and poor comfort.

[0003] Later, handmade soap was developed. Handmade soap is usually made by saponifying oils at a certain temperature and then processed into soaps of different shapes and colors. Handmade soap is clean and gentle, with a neutral pH value and a soft body. However, both ordinary soap and handmade soap are currently mainly used for cleaning and have a single effect.

[0004] In the fast-paced modern life, people's demand for skin care is growing, and it is becoming more and more personalized and scientific. Traditional single-function cleansing products can no longer meet consumers' precise skin care needs at different time periods. In the morning, the skin needs to be refreshed and awakened, remove the oil and dirt accumulated during the night, and maintain moisture balance to prepare for the day's activities. At night, the skin enters the peak period of self-repair and needs deeper cleansing and nourishment to cope with the damage caused by daytime environmental stress.

[0005] Currently, ordinary soaps and handmade soaps have only one function and are unable to distinguish between morning and evening according to consumers’ skin conditions to cleanse and care for the skin. Consumers are usually required to purchase products with different functions for use. Summary of the invention

[0006] In order to provide a soap product that can be used for different skin conditions in the morning and evening, the present application provides an amino acid surfactant mud salt double-sided multifunctional soap and a preparation method thereof.

The black mud powder contains up to 13% of water-soluble salt, more than 20 trace elements such as calcium, magnesium, zinc, selenium, and about 17% of organic matter, among which the content of fulvic acid beneficial to human skin is as high as 4.24%, which is a more natural and healthy skin care ingredient, and the trace element ingredients penetrate into the skin and are absorbed and utilized by the skin, supplement nutrition, and promote the health and repair of the skin, especially specific zinc elements can reduce the inflammatory response of the skin, promote the repair and regeneration of the skin, and the minerals and trace elements in the black mud powder can activate skin cells, promote cell regeneration and repair, and have a certain improvement effect on skin problems such as wrinkles caused by aging. In addition, due to its high adsorption, black mud powder can penetrate deep into the pores, absorb and remove dirt, oil and dead skin cells deep in the pores, thus achieving deep cleansing. This cleaning effect helps reduce pore blockage, prevent the formation of blackheads and acne, and provide a clean environment for skin repair. Black mud powder can also help soften and remove aging keratin cells on the skin surface, promote skin metabolism, and make the skin smoother and more delicate.

[0009] Black mud powder is combined with plant extract A to achieve the effects of cleansing, moisturizing, refreshing and repairing the skin. In addition to amino acid cleansing and moisturizing ingredients, the white part of the soap also uniquely contains magnesium sulfate and sodium chloride. Magnesium sulfate, as a natural mineral, has a certain astringent effect, which helps regulate skin oil secretion, reduce oiliness, and keep the skin fresh. The trace addition of sodium chloride can also have a slight astringent effect and help achieve oil control. Combined with the addition of plant extract B to achieve the effects of cleansing, moisturizing and oil control, use the white part of the soap for cleaning in the morning to help the skin get rid of the grease and dirt accumulated at night, while keeping it moisturized and not dry.

[0012] By adopting the above technical scheme, the angelica extract in the black face part of the present application contains a variety of active ingredients such as vitamins, minerals and amino acids, and is used as a black face ingredient of soap. During the cleaning process, the angelica extract gently cleanses the skin, while promoting blood circulation, helping the skin to better absorb nutrients in subsequent skin care products. In addition, its antioxidant and anti-inflammatory properties help reduce the damage of free radicals to the skin and protect skin cells from external environmental damage; the Centella asiatica extract penetrates deeply into the skin during the cleaning process, reduces inflammation and irritation accumulated during the day, and promotes the repair of damaged skin; the purslane extract is rich in a variety of vitamins and minerals, and gently cleanses the skin during the cleaning process, which has a certain soothing effect, and its anti-inflammatory and antibacterial effects can protect the skin from microbial damage and maintain skin health; Oat alkaloids have excellent anti-inflammatory and soothing effects. They quickly penetrate the skin during the cleaning process, reduce skin inflammation caused by the daytime environment, and have a good soothing effect. Ecdoin has extremely strong moisturizing, repairing and anti-irritation effects. After cleaning, it forms a protective film on the skin surface to lock in moisture. At the same time, its repairing and anti-irritation effects help to strengthen the skin barrier and reduce damage to the skin. Ganoderma lucidum extract has antioxidant and anti-aging effects. It can exert its antioxidant effect to eliminate free radicals and delay skin aging. At the same time, it improves the overall health of the skin and makes the skin tougher and more elastic. Gentiana extract has significant anti-inflammatory, antibacterial and astringent effects. It penetrates deep into the pores during the cleaning process to remove excess oil and dirt. At the same time, its anti-inflammatory and antibacterial effects can reduce the risk of skin inflammation and infection. The astringent effect helps to shrink pores and improve skin texture.

[0013] Finally, the plant extracts in the black side part are rich in antioxidants, anti-inflammatory ingredients and soothing factors as well as black mud powder. When using the black side part of the soap to wash at night, a variety of extracts can promote blood circulation in the skin, reduce inflammation and irritation, enhance skin barrier function, promote cell repair and renewal, remove free radicals and improve skin texture, etc., providing comprehensive care, soothing and repairing effects for the skin. Combined with the synergistic effect of black mud powder, it can more comprehensively repair the skin and achieve the effects of cleansing, moisturizing, refreshing and repairing the skin.

[0014] Optionally, the plant extract B in the white flour part includes 0.1-1.5 parts of sapodilla extract, 0.1-1 parts of licorice extract, 0.1-0.5 parts of sophora flavescens extract, 0.1-0.5 parts of scutellaria baicalensis extract, 0.1-1.0 parts of witch hazel extract, 0.1-0.5 parts of chrysanthemum extract, and 0.1-0.5 parts of verbena extract.

[0015] By adopting the above technical scheme, the soapberry extract of the white part is rich in saponin, which is a natural surfactant with excellent cleaning ability. It can penetrate deep into the pores and effectively remove dirt, oil and dead skin cells on the skin surface, making the skin fresh and clean; Sophora flavescens extract inhibits the growth of bacteria on the skin surface through antibacterial and anti-inflammatory effects, thereby helping to reduce dirt and oil caused by bacterial activity; Licorice extract contains ingredients such as glycyrrhizic acid and glycyrrhetinic acid with excellent moisturizing effects, forming a protective film on the skin surface, locking in moisture, preventing moisture evaporation and thus keeping the skin hydrated; Chrysanthemum extract is rich in vitamins and minerals, has a soothing and moisturizing effect, can relieve the tightness caused by dry skin, and provide the skin with a long-lasting moisturizing effect; Witch hazel extract can penetrate deep into the pores, regulate sebum secretion, reduce oiliness, keep the skin fresh and non-greasy, and its astringent effect also helps to shrink pores and further improve skin texture. In addition, witch hazel extract has a certain moisturizing effect and can adjust the water and oil balance of the skin, so that the skin can be kept moisturized while controlling oil. The antibacterial and anti-inflammatory effects of Sophora flavescens extract can also help reduce excessive oil secretion caused by bacterial activity, improve the skin environment, and control oil secretion; verbena extract can balance the oil secretion of the skin and reduce the clogged pores and acne problems caused by excessive oil. The white part of the soap contains the above extracts, which can achieve the effects of cleaning, moisturizing and controlling oil. Use the white part of the soap for cleaning in the morning to help the skin get rid of the grease and dirt accumulated at night, while keeping it moisturized and not dry.

[0016] Optionally, in the white flour part and the black flour part, the glutamate surfactant is specifically selected from a mixture of 1-5 parts by weight of coconut oil glutamic acid and 24-30 parts by weight of lauroyl glutamic acid.

[0017] By adopting the above technical scheme, cocoyl glutamate and lauroyl glutamate are selected as cleansing ingredients in this application, which are mild, low-irritating and have good foaming properties, can effectively cleanse the skin while maintaining the natural oil balance of the skin and avoiding excessive drying. The combination of the two has excellent cleaning ability and good foam stability, further enhancing the cleaning effect while maintaining the mildness of the formula, helping to maintain the skin's natural barrier function and reducing the feeling of tightness after cleaning.

[0018] Optionally, in the white flour part and the black flour part, the preservative is ethylhexylglycerin; the solvent is a mixture of 1-4 parts by weight of ethanol and 4-11 parts of water; the moisturizer is glycerin, and the pH adjuster is triethanolamine.

[0019] By adopting the above technical solution, ethylhexylglycerin is added as a preservative in both the black and white sides of the soap to inhibit the growth of microorganisms, maintain product stability, and improve the shelf life. A mixture of ethanol and water is used as a solvent to optimize the dissolution and penetration of cleaning ingredients and improve the cleaning efficiency of the soap. At the same time, an appropriate amount of ethanol can also help adjust the consistency and fluidity of the product, making the soap easier to use. Glycerin can lock water to form a protective film, maintain the water-oil balance of the skin, avoid dry skin after cleaning, and also help improve the touch of the soap, making it smoother and more comfortable. The addition of triethanolamine adjusts the pH of the soap, making the soap closer to the natural pH value of the skin, which helps to reduce irritation and discomfort to the skin. Finally, the moisturizing and cleaning effects of the above raw materials are improved in this application to ensure that the soap provides effective cleaning while moisturizing the skin with mildness and moisturizing type.

[0020] In the second aspect, the present application provides a method for preparing an amino acid surfactant mud salt double-sided multifunctional soap, using the following technical solution: A method for preparing an amino acid surfactant mud salt double-sided multifunctional soap comprises the following steps: S1. Prepare black soap solution: mix and disperse the black mud powder in the black part raw material with the solvent, then add glutamic acid surfactant and moisturizer, heat to 85-95° C. to obtain a phase A mixed solution; Heat up and dissolve the pH adjuster and preservative, then add them to the phase A mixture. When the temperature drops to 65-70°C, add the plant extract A, stir for 10-20 minutes, then cool to 55-60°C, let stand, pour into half of the mold, and cool to solidify; S2. Prepare white soap solution: mix the glutamic acid surfactant, moisturizer and solvent in the white part raw material and heat to 85-95° C. to obtain a phase B solution; Then, the pH adjuster and preservative are heated and dissolved, and then added to the phase B solution. When the temperature drops to 65-70°C, plant extract B is added. After stirring for 10-20 minutes, the temperature is dropped to 55-60°C. After standing, the mixture is poured into the other half of the mold. Magnesium sulfate and sodium chloride are added to the middle coating, and the mixture is cooled and solidified. S3, after cooling and solidifying as a whole to a solid state, demoulding, drying and packaging are performed to obtain the amino acid surfactant mud salt double-sided multifunctional soap.

[0021] By adopting the above technical scheme, the method provided by the present application is simple and easy to implement, and easy to realize industrialization. In the present application, the black mud powder is first dispersed and mixed, and then moisturizers and other ingredients are added, which is conducive to the full dissolution and mixing of the raw materials. Then, plant extracts are added during the cooling process to keep the active ingredients from being destroyed by high temperature. After standing, it is poured into half of the mold to reserve space for the subsequent injection of white soap solution. When the white part is formed, magnesium sulfate and sodium chloride are added to the middle coating, which are not only added as oil-control ingredients, but also form a unique texture. Finally, the white soap solution is solidified and combined with the solidified black soap solution to form a double-sided effect, which satisfies the use of the white part for cleansing, moisturizing and oil control in the morning, and the black part for cleansing, moisturizing, soothing and repairing the skin at night.

[0022] Optionally, the black mud powder in step S1 is added after being subjected to the following modification treatment, and the modification treatment comprises the following steps: 1) Mix polyvinyl alcohol and water, then add starch, sodium alginate and sodium bicarbonate, stir and mix, then dry at 55-65°C and granulate to obtain modified starch granules; 2) Mix the saccharifying enzyme and water, raise the temperature to 50-65°C, and adjust the pH to 5.5-6.5 to obtain an enzymatic solution, then add the porous modified starch granules obtained in step 1), react for 20-30 minutes, filter, and then directly place in an environment of -5-0°C, stand for 10-20 minutes, and then place at room temperature for granulation to obtain porous modified starch granules; 3) Mix the black mud powder with water, a dispersant and an emulsifier to form a mixed loading liquid, then add porous modified starch particles, immerse for 1-2 hours under negative pressure and then dry to obtain a modified starch-black mud powder complex, and mix and disperse the modified starch-black mud powder complex with a solvent.

[0023] By adopting the above technical scheme, in the present application, starch is first mixed with polyvinyl alcohol, sodium alginate and sodium bicarbonate and then dried. During the drying process, sodium bicarbonate and water volatilize to form starch particles with a certain pore structure. Then, the starch is treated in a saccharifying enzyme solution. The saccharifying enzyme decomposes the starch at 50-65°C, so that the starch itself forms a pore structure. The pore structure formed by the mixture in step 1) is further optimized. The pore structure of the modified starch particles is then directly allowed to stand in a low temperature environment. On the one hand, the enzyme is inactivated. On the other hand, the pore structure is further adjusted by temperature changes. Then, the loading liquid formed with black mud powder is impregnated under negative pressure conditions, so that the black mud powder particles are absorbed into the pore structure of the modified starch, and the loading of the black mud powder is achieved to obtain a black mud powder-starch composite. Then, the black surface part is mixed with other raw materials to obtain the black mud powder. By adding the black mud powder particles after loading, the problem of easy agglomeration and uneven dispersion of the black mud powder when directly added is solved. Moreover, the addition of starch particles is coordinated to further achieve impurity adsorption and improve the cleaning and oxidation effects.

[0024] Optionally, during the modification process of black mud powder, each raw material is added in the following proportions: In step 1), the mass ratio of polyvinyl alcohol to water is 1:(2-3), the mass ratio of starch, sodium alginate and sodium bicarbonate is 1:(0.1-0.3):(0.3-0.5), and the amount of starch added is 2-3 times the mass of the amount of polyvinyl alcohol added; In step 2), the ratio of saccharifying enzyme to water is 1:(5-8), and the enzymatic solution immerses the porous modified starch particles; In step 3), the mass ratio of black mud powder, water, dispersant and emulsifier added is 1:(1-2):(0.1-0.3):(0.05-0.1), and the mixed loading liquid immerses the porous modified starch particles, and the negative pressure condition is -900-(-600) Kpa.

[0025] Optionally, in step 3), the emulsifier is one or more of sodium fatty acids and phospholipid emulsifiers, and the dispersant is sodium sulfate of fatty alcohol polyoxyethylene ether.

[0026] Optionally, the modified starch-black mud powder complex obtained in step 3) is further subjected to inclusion modification, and the specific operation is: cyclodextrin, sodium polyacrylate and polyvinyl pyrrolidone are mixed with water in a mass ratio of 1: (0.2-0.3): (0.1-0.3): (1.2-1.5) to obtain a spray solution, and then spray-dried on the surface of the prepared modified starch-black mud powder complex to form an inclusion complex, and then mixed and dispersed with a solvent, wherein the added mass ratio of the spray solution to the modified starch-black mud powder complex is 1: (1.2-1.4).

[0027] By adopting the above technical scheme, the prepared modified starch-black mud powder composite powder is further included by cyclodextrin and the like, and the black mud powder composite is included by utilizing the cavity structure of cyclodextrin to form a stable inclusion complex. Cyclodextrin can effectively shield the negative impact of the external environment on the black mud powder, and at the same time increase its solubility in water, which is beneficial to its compatibility with the glutamic acid surfactant system. Sodium polyacrylate and polyvinyl pyrrolidone play a good suspending role, so that the prepared composite can be suspended in the soap liquid system without sedimentation and is evenly dispersed, so that the black mud powder is more evenly distributed and will not agglomerate or settle. The subsequent black surface part of the soap will not be stratified, and the above inclusion treatment can also play a certain buffering role, preventing the active ingredients from being reduced due to the impact of high temperature on the black surface part when the white surface part is poured after the black surface part is prepared, thereby improving the final cleaning and skin care effect.

[0028] In summary, this application has the following beneficial effects: 1. The soap prepared in the present application has a black and white side, and both sides are added with glutamic acid surfactant as a cleaning ingredient, which is mild and non-irritating, and will not cause strong degreasing, dryness, or itching of the skin after use; 2. In this application, a black and white double-sided soap is prepared, and both sides contain cleansing and moisturizing basic ingredients. On the basis of cleansing, the white side is used for cleaning in the morning to achieve the effects of cleansing, moisturizing and oil control, while the black side is used for cleaning at night to achieve the effects of cleansing, moisturizing, soothing and repairing the skin. According to the different skin conditions in the morning and evening, the two major effects of cleansing, oil control and repair are designed respectively, achieving multi-faceted effects; 3. The black surface part of the present application adopts black mud powder and a variety of plant extracts. The plant extracts are rich in antioxidants, anti-inflammatory ingredients and soothing factors as well as black mud powder. When the black surface part of the soap is used for washing at night, a variety of extracts can promote skin blood circulation, reduce inflammation and irritation, enhance skin barrier function, promote cell repair and renewal, remove free radicals and improve skin texture, etc., to provide comprehensive care, soothing and repair effects for the skin. In combination with the synergistic effect of black mud powder, the skin can be repaired more comprehensively to achieve the effects of cleaning, moisturizing, refreshing and repairing the skin. 4. In addition to amino acid cleaning and moisturizing ingredients, the white flour part of the soap of the present application also uniquely adds magnesium sulfate and sodium chloride. Magnesium sulfate, as a natural mineral, has a certain astringent effect, helps regulate skin oil secretion, reduces oiliness, and keeps the skin fresh, while a trace amount of sodium chloride can also have a slight astringent effect, which helps to achieve oil control. Combined with the addition of plant extract B, the effects of cleaning, moisturizing and oil control can be achieved. In the morning, the white flour part of the soap is used for cleaning to help the skin get rid of the grease and dirt accumulated at night, while keeping it moisturized and not dry.

[0044] Performance Testing The double-sided soaps prepared in the examples and comparative examples of the present application were used as test examples. Five volunteers were recruited in each group of test examples to clean their hand skin. The skin comfort and skin condition after use were recorded based on the volunteers' feedback. The soaps prepared in the examples and comparative examples of the present application were used for washing. Whether it was the white part or the black part, the bubbles were abundant during washing, and the skin was clear and not greasy. After washing, the skin was moisturized without tightness, dryness, or itching. Moreover, after using the black part for one week, the skin with inflammatory symptoms such as skin redness, swelling, and itching was significantly improved.

[0045] In addition, before using the soap, the sebum content and moisture content of the hands of the subjects were tested with a skin tester, and the initial value was recorded. Then, the white part of the soap was used for washing in the morning, and then rinsed with water. After washing, the sebum content and moisture content were measured again after waiting for 4 hours, and the measured values ​​were recorded. The changes in sebum content and moisture content before and after use were compared to evaluate the oil control and moisturizing effects of the soap. The test results are shown in Table 1 below; Table 1: Referring to the test results in Table 1 above, "+" in the test results in Table 1 above indicates an increase in water content, and "-" indicates a decrease in oil content. Referring to the test results in Table 1 above, it can be seen that the soap prepared in the embodiment of the present application has excellent oil removal and moisturizing effects. Referring to the test results of Example 1 and Example 4-6, it can be seen that after the black mud powder is modified by modified starch, on the one hand, the black mud powder is more evenly dispersed, and on the other hand, the adsorption of starch combined with the black mud powder has a better adsorption and cleaning effect, a better oil removal effect, and is more conducive to the penetration of the moisturizing component to achieve a better moisturizing effect. Combined with Example 7- According to the test results of Example 9, after the black mud powder is coated with a cyclodextrin inclusion layer, the impact of high temperature on the black surface part when pouring white soap may be improved, and it has more active ingredients, which can play a better cleaning role and significantly improve its oil control and moisturizing effect. Combined with the test results of Example 10 and Example 11, in Example 10, starch and black mud powder are directly mixed to form pores and then added. It may be that the pore structure of starch is small, which is effective for the adsorption of black mud powder, the loading amount is small, and the final efficacy is reduced. In Example 11, the starch is enzymatically hydrolyzed to form pores and then loaded, and the pore structure is still small, the loading is limited, and the final efficacy is reduced.

[0046] Referring to the test results of Example 1 and Comparative Example 1, black mud powder was not added to the raw materials, and the deep adsorption and cleaning effect was reduced, and the moisturizing effect was also significantly reduced. Combined with the test results of Comparative Examples 2 and 3, it can be seen that when plant extracts were not added to the raw materials, the oil control and moisturizing effects were reduced.

[0047] In order to observe the washing effect of the soap more intuitively, the washing effect of the soap on the surface of the black surface, the part in contact with the white surface and the middle of the black surface in the embodiment and the comparative example was tested, and the whiteness of the white cotton knitted fabric was tested and the whiteness retention value was calculated. The test results are shown in Table 2 below.

[0048] Table 2: Referring to the test results in Table 2 above, it can be seen that in Example 1, the washing effects of soaps from different regions are quite different, and the washing effect is better near the white part. This is because when the black soap solution is prepared, it is finally left to stand and then poured into the mold, and the black mud powder settles to the bottom and finally falls near the white area. Combined with the test results of Examples 4-6, it can be seen that when the black surface part is used for washing, not only the washing effect is improved, but also the difference in washing effects between different regions is reduced. Combined with the test results of Examples 7-9, the washing effects of different regions are basically the same, while the washing effects in Examples 10 and 11 are reduced, and the washing effects of different regions also have certain differences.
