Description

Technical Field

[0001] The present application relates to the technical field of daily chemicals, and in particular to a three-in-one scrub cleansing tablet for shampooing, cleansing and bathing. Background Art

[0002] With the diversification of personal care products, consumers are increasingly demanding multifunctional, effective, and gentle cleansing products. Currently, scalp, face, and body scrubs on the market mainly rely on sea salt particles, sucrose, hydrated silica, etc. as abrasive ingredients.

[0003] The Chinese invention patent application number CN202210166794.3 discloses a moisturizing scalp scrub ointment and its preparation method, which is composed of a cleansing oil system and sea salt scrub particles. The sea salt scrub particles can remove scalp keratin through friction, solving the problem of high irritation of sea salt particles to the scalp and the dryness caused to the hair. However, the problem of the stability of sea salt particles is not discussed. During the actual use of the scrub, as the bottle cap of the scrub bottle is opened multiple times, water vapor will enter the bottle, causing the stability of the sea salt particles to decrease. The sea salt particles gradually become smaller or dissolve in the bottle, affecting its exfoliating performance. The Chinese invention patent application number CN202111395070.8 discloses a bath scrub block that uses sucrose as scrub particles. In actual use, there is also the problem of the scrub particles dissolving too quickly, resulting in an insignificant cleaning effect. A Chinese invention patent with application number CN202310571208.8 discloses an abrasive cleansing gel and a preparation method thereof, which uses hydrated silica as abrasive particles. Hydrated silica may excessively remove natural oils on the skin surface, causing dry skin.

[0004] To sum up, how to strike a balance between cleaning power, stability and mildness in scrub products is a difficult problem that needs to be solved urgently. Summary of the Invention

[0005] The purpose of the present application is to solve the technical problem that the above-mentioned scrub products are difficult to balance between cleaning power, stability and mildness. The present application provides a three-in-one scrub cleaning tablet for shampooing, cleansing and bathing. The tablet has the characteristics of convenient measurement and high storage stability. The scrub cleaning tablet is partially paste-like after being moistened with a small amount of water. It gradually dissolves with friction and increase in water volume. The foam is rich and delicate, the cleaning performance is good, and the friction is gentle and the irritation to the skin is small. At the same time, the scrub cleaning tablet of the present application is added with plant extracts, and there is no need to add additional chemical antibacterial agents. It has an inhibitory effect on Malassezia furfur and has an anti-dandruff effect.

[0006] In the first aspect, the present application provides a three-in-one scrub cleansing tablet for shampooing, cleansing and bathing, which adopts the following technical solution: A three-in-one scrub cleaning tablet for shampooing, cleansing and bathing, wherein the raw materials for preparing the three-in-one scrub cleaning tablet for shampooing, cleansing and bathing include, by weight percentage: First structuring agent 10%-35% Second structuring agent 4%-15% First surfactant 15%-34% Second surfactant 3%-10% Frosted particles 5%-16% Emollient 1%-6% Water softener 1%-6% Plant extract 0.5%-5% Additives 0.5%-5% Water balance; The first structuring agent is polyvinyl alcohol; The second structuring agent comprises at least one of carboxymethyl chitosan, sodium carboxymethyl cellulose, carrageenan and pectin; The scrub particles include at least two of polygonum multiflorum powder, arborvitae leaf powder, ginger powder, angelica powder and coconut shell powder. Other scrub particles such as tea powder, red bean seed powder, rice husk powder, etc. that can be used in shampoo, facial cleanser and bath products are also suitable for the above scrub cleaning tablets.

[0007] By adopting the above technical solution, the first structuring agent and the second structuring agent cooperate with each other to form a stable sheet structure for the scrub cleaning sheet, which is easy to store. The viscosity of the aqueous solution of the first structuring agent and the second structuring agent increases with decreasing temperature. At room temperature, the scrub cleaning sheet is in a gel-like state when in contact with water. As the temperature rises, the gel-like state changes to a flowing liquid. This ensures that the scrub cleaning sheet has a certain hardness and shape when dry, but also a certain degree of flexibility, and is not too hard or easily powdered. When wet, it can gradually dissolve, effectively slowing the dissolution rate of the scrub cleaning sheet when in contact with water, and avoiding the problem of poor cleaning effect and moisturizing performance caused by the scrub cleaning sheet dissolving too quickly. The abrasive particles are directly obtained by grinding natural materials such as plant stems, leaves, and shell powder. When the slurry is prepared at high temperature, the active substances in the plant stems, leaves, and shell powder can be fully dissolved. The remaining plant framework contains cellulose, pectin, etc., which have high stability as abrasive particles, mild friction, low irritation, and are environmentally friendly. The first and second surfactants provide cleaning power and dense foam. Combined with the addition of plant extracts, water softeners, emollients and adjuvants, a small amount of water makes the scrub cleansing sheet into a paste-like state during use, which can adhere to the surface of tools such as brushes or bath towels. During the friction process, the gel properties of the first and second structuring agents can bind the scrub particles, improving the exfoliation effect. The particles are fine and non-irritating. When rinsed with warm water, the viscosity of the first and second structuring agents decreases, making it easy to rinse. In addition, foaming occurs during the friction process, cleaning thoroughly without residue. After use, the skin is moisturized and not tight. The average WE value is 13.04%-26.09%, the average OE value is (-8.33%)-(-5.00%), and the cleaning rate reaches 70.00%-90.37%, achieving a balance between cleaning power, stability and mildness.

[0008] Optionally, the first surfactant includes an anionic surfactant and an amino acid surfactant; The anionic surfactant includes at least one of sodium alkyl glycoside sulfosuccinate, sodium lauroyl methyl isethionate and sodium cocoyl isethionate; The amino acid surfactant includes at least one of sodium methyl lauroyl taurate, sodium methyl cocoyl taurate, sodium cocoyl methyl taurate, sodium lauroyl glutamate, sodium lauroyl sarcosinate and sodium cocoamidopropionate.

[0009] By adopting the above technical solution, anionic surfactants have strong cleaning and decontamination capabilities and can quickly produce a large amount of foam, but the cleaning power is too strong when used alone, which can easily cause water and oil imbalance in the skin; amino acid surfactants have mild decontamination capabilities and can neutralize the irritation caused by anionic surfactants; the combination of anionic surfactants and amino acid surfactants can form dense foam, maintain cleaning power, and facilitate rinsing without being too irritating.

[0010] Optionally, in the first surfactant, the weight ratio of the anionic surfactant to the amino acid surfactant is 2-16:1.

[0011] By adopting the above technical solution, when the weight ratio of the anionic surfactant to the amino acid surfactant is greater than 16:1, the resulting scrub cleaning sheet has too strong a cleaning power, and the skin moisturizing effect after use is average, requiring further skin care and moisturizing. When the weight ratio of the anionic surfactant to the amino acid surfactant is lower than 2:1, the resulting scrub cleaning sheet cannot be formed into sheets or the sheets are dry and brittle, and have poor stability.

[0012] Optionally, the second surfactant includes a nonionic surfactant and an amphoteric surfactant; The nonionic surfactant comprises at least one of alkyl glycoside, maltoside, sophorolipid and rhamnolipid; The amphoteric surfactant includes at least one of cocamidopropyl betaine, cocamidopropyl hydroxysulfobetaine and cocamidopropylamine oxide.

[0013] Optionally, in the second surfactant, the weight ratio of the nonionic surfactant to the amphoteric surfactant is 1:0.25-4.

[0014] By adopting the above technical solution, non-ionic surfactants are relatively mild and cause less damage to the skin barrier, while amphoteric surfactants effectively extend the life of the foam and increase the viscosity of the system. The combination of the two has better overall performance and effectively reduces costs.

[0015] Optionally, the plant extract includes at least one of rice husk extract, agarwood extract, soapberry extract and camellia oleifera extract.

[0016] By adopting the above technical solution, rice husk extract, agarwood extract, soapberry extract and camellia oleifera extract are all pure natural ingredients extracted from plants and contain a variety of active ingredients. Antibacterial tests have shown that the scrub cleaning tablets have an inhibitory effect on the growth of Malassezia furfur and have an anti-dandruff effect. At the same time, it can avoid the drug resistance problem caused by long-term use of chemical antibacterial agents such as selenium disulfide and pyridone ethanolamine salt, and help maintain the health of skin and hair.

[0017] Optionally, the emollient includes at least two of squalane, biomimetic phospholipids, D-panthenol, sodium hyaluronate, coconut oil and shea butter.

[0018] Optionally, the water softener includes at least one of sodium polyaspartate, sodium polyglutamate, trisodium methylglycine diacetate and lactic acid.

[0019] Optionally, the auxiliary agent includes at least one of glycerol, butylene glycol, 1,2-hexanediol and sorbitol.

[0020] In a second aspect, the present application provides a method for preparing a three-in-one scrub cleansing tablet for shampooing, cleansing and bathing, using the following technical solution: The preparation method of the above-mentioned three-in-one scrub cleaning tablet for shampooing, cleansing and bathing comprises the following preparation steps: S1, stirring and mixing the auxiliary agent and the second structuring agent to obtain a first mixed solution; S2, adding the first structuring agent to water and heating it to 85-90° C., stirring at constant temperature until it is fully swollen to a homogeneous solution, then adding the first mixed solution, continuing to stir at constant temperature to obtain a second mixed solution; S3, cooling the second mixed liquid to 70° C., adding abrasive particles and a water softener, and stirring to obtain a third mixed liquid; S4, cooling the third mixed liquid to 50-60° C., adding a softener and a plant extract, and stirring evenly to obtain a slurry; S5, drying, shaping, sheeting and slicing the slurry to obtain.

[0021] By adopting the above technical solution, the preparation process is temperature-controlled and simple processes such as mixing are adopted. The preparation method is simple, the process is highly controllable, and it is suitable for large-scale production.

[0022] Compared with the prior art, the present invention has the following beneficial effects: 1. This application is a tablet with a stable structure, easy to store and good stability; 2. The viscosity of the aqueous solution of the first and second structuring agents of the present application increases with decreasing temperature. After being moistened with a small amount of water, it becomes partially paste-like. It gradually dissolves with friction and increased water volume, effectively slowing the dissolution rate of the scrub cleaning sheet when exposed to water, avoiding the problem of poor cleaning effect and moisturizing performance caused by the scrub cleaning sheet dissolving too quickly. 3. This product has rich and delicate foam, cleans thoroughly without residue, and leaves the skin moisturized and not tight after use; the scrub particles have gentle friction and little irritation to the skin. After use, the average WE value is 13.04%-26.09%, the average OE value is (-8.33%)-(-5.00%), and the cleaning rate reaches 70.00%-90.37%; 4. This application, by adding plant extracts, has an inhibitory effect on the growth of Malassezia furfur, has an anti-dandruff effect, and helps maintain the health of the skin and hair.

[0030] A three-in-one scrub cleansing tablet for shampooing, cleansing and bathing, the raw material composition and content used in its preparation are shown in Table 3 below, calculated by weight percentage: Table 3 Composition and content of raw materials in Example 1

[0031] The preparation method of the above-mentioned three-in-one scrub cleaning tablet for shampooing, cleansing and bathing comprises the following preparation steps: S1, stirring and mixing the auxiliary agent (glycerol) and the second structural agent (carboxymethyl chitosan) to obtain a first mixed solution; S2. Add the first structuring agent (polyvinyl alcohol) to deionized water and heat it to 85-90° C., stir at constant temperature until it is fully swollen to a homogeneous solution, then add the first mixed solution, continue stirring at constant temperature for 20 minutes, then add the first surfactant (anionic surfactant and amino acid surfactant) and the second surfactant (nonionic surfactant and amphoteric surfactant), continue stirring at constant temperature until a homogeneous liquid is obtained to obtain a second mixed solution; S3, cooling the second mixed solution to 70° C., adding abrasive particles (Polygonum multiflorum powder and Platycladus orientalis leaf powder) and a water softener (sodium polyaspartate), and stirring at a constant temperature for 30 minutes to obtain a third mixed solution; S4, cooling the third mixed solution to 50-60° C., adding emollients (bionic phospholipids and shea butter) and plant extracts (rice husk extract), and stirring at a constant temperature for 20 min until uniform to obtain a slurry; S5, the slurry is dried, formed, sheeted and sliced ​​in sequence to obtain a finished product of a frosted cleaning sheet; the finished product is shown in the figure below. Figure 1 shown.

[0032] The obtained scrub cleaning sheet was subjected to antibacterial test, and the test results are shown in Table 4 below: Table 4 Antibacterial test results According to the results of Table 4 above, the logarithm of the number of recovered colonies in Example 1 and the control group were analyzed for homogeneity of variance and then a paired t-test was performed. The results showed that the difference between the number of colonies in the control group and the number of colonies in Example 1 was greater than 0.25, and P 0.05 <0.01, which shows a significant difference between the two. This shows that the scrub cleaning sheet obtained in Example 1 has a dandruff removal effect.

[0033] The volunteers used the scrub cleaning sheet obtained above to clean their scalps, and the scalp was tested before and after cleaning. The scalp test is shown in the figure below. Figure 2 and Figure 3 The results showed that the volunteers' scalps were clogged with oil when not washed, but after washing with the scrub cleansing sheet, the oil content of the scalp was significantly reduced. This shows that the scrub cleansing sheet has good cleaning power, can absorb and remove sebum, and at the same time will not damage the scalp environment and cause problems such as dandruff.

After cleaning, the skin is smooth and soft, the hair is easy to comb, and there is no residue after shampooing; the average OE is (-8.33%)-(-5.00%), and the average WE is 13.04%-26.09%. That is, after using the scrub cleaning sheet, the oil content of the skin is reduced, the exfoliation effect is good, but it does not excessively degrease, and the irritation to the skin is small. It effectively avoids damaging the skin barrier, maintains the water and oil balance, and achieves a balance among cleaning power, stability and mildness.

[0077] In Comparative Example 1, since no second structuring agent, such as carboxymethyl chitosan, was added, the resulting scrub cleaning sheet dissolves quickly and the remaining raw materials are released quickly, thereby weakening its exfoliating and grease-removing effects. The average WE value is only 4.35%, and the average OE value is only -5.56%. Further skin care is required after use, and the cleaning rate is reduced by 40.17% compared to Example 1. This shows that when the first and second structuring agents are used in combination, the scrub cleaning sheet effectively slows down the dissolution rate when exposed to water, resulting in better cleaning and moisturizing effects. The scrub cleaning sheet also has better stability, cleaning power, and mildness, which helps to enhance the user experience.

[0078] After using Comparative Examples 2-3, average WE values ​​ranged from 6.68% to 14.46%, and average OE values ​​ranged from -6.21% to -4.37%. Meanwhile, cleaning rates were only 63.70% to 67.04%, indicating a decrease in performance. Furthermore, scores for various performance indicators in the evaluation also decreased to varying degrees. This indicates that when the amounts of the first and second structuring agents are within the ranges used in Examples 1-8, a better synergistic performance effect is achieved.

[0079] In Comparative Example 4, the scrub particles are made of corn starch. The corn starch particles are soft and have natural oil absorption, which can provide a certain amount of physical friction. However, corn starch will dissolve quickly when it comes into contact with water. Compared with plant scrub particles such as Polygonum multiflorum powder and Platycladus orientalis leaf powder, the scrub effect is insufficient, resulting in poor cleaning effect. The cleaning rate after use is only 44.81%, and the OE average value is -1.76%, and the WE average value is -4.17%, and the cleaning effect is not good.

[0080] Comparative Example 5 uses hydrated silica as the abrasive particles. Hydrated silica possesses strong cleansing power, effectively removing oil and dead skin cells. Its cleansing rate reached 79.26%. However, the skin's moisture content decreased after cleansing, with an average WE value of -6.67% and an average OE value of 4.84%. This reduced the moisture content and increased the oil content compared to the emollient-free sample in Comparative Example 6. This suggests that while hydrated silica offers a high cleansing power, it disrupts the skin's water-oil balance and is highly irritating. This can lead to dry scalp and skin, resulting in tightness and scaling.

[0081] After use, the average WE values ​​for Comparative Examples 7-8 ranged from 8.87% to 14.13%, the average OE values ​​ranged from (-6.93%) to (-2.33%), and the cleaning efficiency ranged from 67.41% to 76.67%. When the amount of abrasive particles was low, the cleaning effect was insufficient, while when the amount of abrasive particles was high, the graininess increased during use, resulting in a decreased user experience. This indicates that using abrasive particles within the range of Examples 1-8 resulted in better performance.

[0082] In Comparative Example 9, the abrasive particles using only Polygonum multiflorum powder showed a decrease in overall performance compared to the abrasive particles using both Polygonum multiflorum powder and Platycladus orientalis leaf powder. The average WE value decreased by 62.91%, the average OE value increased by 61.94%, and the user evaluation score also decreased. This indicates that using at least two ingredients in a abrasive particle combination has better performance than using only one ingredient alone.

[0083] In Comparative Example 10, the first surfactant used solely an anionic surfactant (sodium alkyl glycoside sulfosuccinate), and in Comparative Example 11, the first surfactant used solely an anionic surfactant (sodium α-olefin sulfonate). The resulting scrub cleansing sheet had strong cleaning power, with a cleaning rate of 84.07%-85.56%. However, use caused an imbalance in the skin's water-oil balance and reduced moisturizing properties. Combining an anionic surfactant with an amino acid surfactant produced a dense foam, maintained cleaning power, and facilitated rinsing without excessive irritation.

[0084] In Comparative Example 12, the second surfactant used alone an amphoteric surfactant (cocamidopropyl hydroxysulfobetaine), and the resulting scrub cleaning sheet had reduced cleaning power, excessive foam made rinsing difficult, and increased cost. In Comparative Example 13, the second surfactant used alone a nonionic surfactant (PEG-100 stearate), and the resulting scrub cleaning sheet had reduced cleaning power and poor foam stability. The combination of nonionic surfactants and amphoteric surfactants resulted in better overall performance.

[0085] In Comparative Examples 14-15, after use, the average WE values ​​were (-5.79%) to 7.43%, the average OE values ​​were (-5.64%) to (-4.75%), and the cleaning rates were 75.56% to 81.85%. There were cases where the cleaning power was either too strong or insufficient, and the overall effect was reduced. Furthermore, when the weight ratio of the anionic surfactant to the amino acid surfactant was less than 2:1, the tablets could not be formed or were dry and brittle. Therefore, when the weight ratio of the anionic surfactant to the amino acid surfactant in the first surfactant, and the weight ratio of the nonionic surfactant to the amphoteric surfactant in the second surfactant, were both within the ranges of Examples 1-8, the overall performance was better.

[0086] In Comparative Example 16, the softener using only biomimetic phospholipids showed a decrease in overall performance, particularly in moisturizing effect and WE average, compared to the softener using both biomimetic phospholipids and shea butter. This indicates that using at least two softeners in combination has better performance than using either alone.

[0087] In Comparative Example 17, an equal weight of polyvinyl alcohol was used instead of the plant extract, i.e., no plant extract was added. The exfoliating effect was reduced, and there was still a certain amount of dandruff after use. The cleaning effect was not good, and the moisturizing effect was reduced. The hair was not smooth enough after washing.

[0088] After using the commercially available sea salt scrub in Example 18, the cleaning power was only 50.00%, the stability was insufficient, and the skin lost water severely after use, causing the skin's water-oil balance to be unbalanced. Excessive dryness caused the skin to secrete a large amount of oil due to the water-oil imbalance.
