Description

TECHNICAL FIELD

[0001] The present application relates to the field of skin care, in particular to a whitening material liquid capable of softening keratin, a production process and a mask. BACKGROUND

[0002] The stratum corneum is the outermost part of the epidermis, which is composed of dead keratinocytes without nuclei. When these cells fall off, the cells located in the basal layer are gradually pushed up to form a new stratum corneum. Although the stratum corneum is dead cells without vitality, it contains rich keratin, which is the main barrier to prevent external substances from entering the human body and water loss in the body.

[0003] However, due to the decreased metabolism of adult skin, the skin on the face is prone to excessive accumulation of keratin, that is, excessive keratin. When keratinocytes are sufficient in water, the skin gloss is naturally good, but when the water is insufficient, the keratinocytes will start to shrink, the arrangement will become uneven and the cell gap will become large, and the skin will look rough and dull; and the accumulation of keratin carrying dust and bacteria blocks the pores, causing inflammation and closed pores, acne, and long-term blockage of keratin in the pores also causes large pores.

[0004] At present, the treatment of skin keratin usually uses fruit acid and salicylic acid to apply to the skin, and the fruit acid and salicylic acid can dissolve the connection structure of keratin and skin, so that the keratin falls off; or uses skin care water containing fruit acid and salicylic acid for daily skin care, so as to alleviate the keratin problem of the skin. After the reduction of keratin, not only can the problems of acne skin and large pores be reduced, but also the rough and dull skin can be improved.

[0005] However, fruit acid and salicylic acid have certain irritation, which is not suitable for some relatively sensitive people. After using fruit acid and salicylic acid, the skin barrier of sensitive people is damaged, thereby causing more skin problems; and using products containing fruit acid and salicylic acid, improper use often leads to excessive exfoliation, which causes the skin barrier to be damaged due to insufficient keratin. SUMMARY

[0006] In order to more gently and effectively exfoliate, the present application provides a whitening material liquid capable of softening keratin, a production process and a mask.

[0007] The whitening material liquid capable of softening keratin provided by the present application adopts the following technical scheme:

[0008] A whitening material liquid capable of softening keratin comprises the following components and contents:

[0009] Glycerin 1-3%, Sodium polyglutamate 0.01-0.05%, Sodium hyaluronate 0.01-0.20%, Arginine 0.01-0.20%, Skin probiotics 0.01-0.20%, Tranexamic acid 1.00-3.00%, Oat extract 0.1-1.0%, Troxerutin 0.01-0.20%, Anti-allergen 0.1-1.0%, Antioxidant 0.1-1.0%, Whitening agent 1.00-3.00%, Stabilizer 0.05-0.20%, Butylene glycol 1.00-3.00%, Balance: Water.

[0010] By employing the above-mentioned technical solution, glycerin, sodium hyaluronate, and sodium polyglutamate all possess excellent water-absorbing properties, thus providing excellent moisturizing effects on the skin. This softens the stratum corneum, making it easier to remove accumulated dead skin cells during subsequent cleansing, reducing damage to the skin barrier caused by exfoliation. Furthermore, because sodium hyaluronate can penetrate deep into the epidermis, promoting nutrient supply and waste excretion, and because arginine plays a crucial role in cell proliferation and energy metabolism, sodium hyaluronate can carry and promote arginine penetration into the skin, better promoting epidermal cell proliferation and differentiation, thus accelerating skin metabolism and enabling the basal layer to generate new cells more quickly for renewal, further accelerating the shedding of dead skin cells. This process of promoting the shedding of dead skin cells reduces damage to sensitive skin, making it suitable for individuals with sensitive skin. It can also be used daily, providing a gentler way to soften and remove dead skin cells during routine skincare.

[0011] Skin probiotics enhance the proliferation of skin microorganisms and balance the skin barrier flora, alleviating skin problems caused by microbial imbalance due to keratin buildup. They also reduce inflammation caused by excessive keratin, improving acne and closed comedones. Meanwhile, oat extract and troxerutin have calming and anti-inflammatory effects, working synergistically with skin probiotics to better alleviate skin inflammation and allergies. Furthermore, these substances, combined with anti-allergy agents, further improve inflammation and allergies caused by clogged pores due to keratin buildup. This process reduces skin irritation during skincare and better improves inflammation caused by excessive keratin, providing a gentler exfoliation experience.

[0012] Oat extract and troxerutin both have excellent antioxidant properties, and work synergistically with antioxidants to reduce skin damage from UV rays and pollutants.

[0013] Sodium polyglutamate (SPG) inhibits tyrosinase activity; while tranexamic acid (TCA) reduces prostaglandin secretion by binding to plasminogen activator and keratinocytes. Prostaglandins are a factor that stimulates tyrosinase activity, thus inhibiting tyrosinase activity. SPG and TCA inhibit tyrosinase activity through different mechanisms, achieving a complementary effect. Combined with whitening agents, they can better inhibit melanin production, thus achieving a whitening effect.

[0014] Optionally, the whitening agent includes the following components and their amounts:

[0015] 1,2-Hexanediol 25-27%, papain 23-25%, caprylyl glycol 14-16%, sclerotium gum 12-14%, glycerol 7-9%, balance water.

[0016] By employing the above-mentioned technical solution, papain readily forms a complex with copper ions in the melanin formation reaction, thereby reducing melanin formation and achieving a whitening effect. Simultaneously, papain can also promote the exfoliation of the skin's keratinocytes. Through the addition of a small amount of papain, in synergy with glycerin, sodium hyaluronate, sodium polyglutamate, and arginine, it can accelerate the exfoliation process during keratin softening and the replacement of dead keratinocytes with new cells, thus enhancing the exfoliation effect while being as gentle as possible.

[0017] Optionally, it may also include 0.01-0.20% ethylhexylglycerin, 0.1-1.0% p-hydroxyacetophenone, 0.1-1.0% p-hydroxyacetophenone, 1.00-3.00% butylene glycol, and 0.1-1.0% hexanediol.

[0018] By adopting the above technical solutions, both butylene glycol and hexanediol exhibit antibacterial effects. Butylene glycol also has moisturizing properties and a lower viscosity than glycerin, improving the user comfort of the solution. Ethylhexylglycerin and p-hydroxyacetophenone both possess antibacterial and preservative effects. Furthermore, ethylhexylglycerin has a synergistic effect with alcohols and glycols, enhancing the antibacterial activity of butylene glycol and hexanediol, thereby further improving the preservative properties and ease of storage of the solution.

[0019] Optionally, the skin probiotic includes the following components and their amounts:

[0020] The composition consists of 35-45% Lactobacillus fermentation products, 15-20% 1,2-hexanediol, 10-15% Lactobacillus, 4-6% xanthan gum, 3-4% fructooligosaccharides, 1-2% α-glucan oligosaccharides, and the remainder is water.

[0021] By adopting the above technical solution, Lactobacillus is used as a probiotic, and then supplemented with Lactobacillus fermentation products, fructooligosaccharides and α-glucan oligosaccharides to form prebiotics, so as to balance the flora of the skin barrier.

[0022] Optionally, the anti-allergy agent includes the following components and their amounts:

[0023] The ingredients are: 16-18% matricaria flower extract, 12-14% 1,2-hexanediol, 8-10% butylene glycol, 8-10% scutellaria baicalensis root extract, 7-9% licorice root extract, 7-9% tea extract, 5-7% ethylhexylglycerin, 2-4% centella asiatica extract, 2-4% polygonum cuspidatum root extract, 1-2% rosemary leaf extract, and the balance being water.

[0024] By adopting the above technical solution, the above substances have soothing and anti-allergic effects. By compounding the substances according to the above content ratio, the substances synergistically enhance each other and achieve better anti-allergic effects.

[0025] Optionally, it also includes 0.01-0.20% of hydroxyphenylpropionamide benzoic acid.

[0026] By adopting the above technical solution, hydroxyphenylpropionamide benzoic acid can resist histamine and has the effects of anti-irritation and antipruritic, which can effectively inhibit skin itching and erythema caused by histamine.

[0027] Optionally, the antioxidant includes the following components and their amounts:

[0028] Sodium ascorbate 22-24%, 1,3-propanediol 16-18%, lecithin 12-14%, lutein 10-12%, tocopherol 6-8%, balance water.

[0029] By adopting the above technical solutions, sodium ascorbate, lutein and tocopherol all have excellent antioxidant properties, which can work synergistically with oat extract and troxerutin to reduce skin damage caused by ultraviolet rays and pollutants.

[0030] Optionally, the stabilizer includes at least one of Carbopol U21 and Sclerotinia gum.

[0031] Secondly, the production process of the whitening liquid that can soften the stratum corneum provided in this application adopts the following technical solution:

[0032] A manufacturing process for a whitening liquid that can soften keratin includes the following steps:

[0033] The components are allocated into phase A, phase B, phase C, phase D, phase E, and phase F materials according to the above proportions.

[0034] The A-phase material includes glycerin, sodium polyglutamate, stabilizers, sodium hyaluronate, and skin probiotics; the B-phase material includes arginine; the C-phase material includes butylene glycol, ethylhexylglycerin, p-hydroxyacetophenone, and 1,2-hexanediol; the D-phase material includes butylene glycol and hydroxyphenylpropionamide benzoic acid; the E-phase material includes tranexamic acid, oat extract, and troxerutin; and the F-phase material includes anti-allergy agents, antioxidants, and whitening agents.

[0035] The pre-formulation of the C-phase material and the pre-formulation of the D-phase material are carried out.

[0036] Add each component of phase A material sequentially, heat and stir to 85-90℃, keep warm for 27-32 minutes, then stir and cool down; when the temperature drops to below 42-47℃, add the well dispersed and dissolved phase B material and stir evenly; then add the pre-prepared phase C and phase D materials and stir evenly; then add the well dispersed and dissolved phase E material and stir evenly; then add each component of phase F material sequentially and stir evenly to obtain the liquid.

[0037] By adopting the above technical solution and through the above preparation process, it is possible to make the substances more uniformly dispersed to form a liquid without affecting the stability and characteristics of each substance, so as to make the solution of the liquid more stable.

[0038] Optionally, the pre-preparation of the C-phase material includes the following steps: heating and stirring each component in the C-phase material to 60-65°C to ensure complete dispersion and dissolution of the solid material, and then cooling it to room temperature for later use.

[0039] The pre-preparation of the D-phase material includes the following steps: heating and stirring each component of the D-phase material to 60-65°C to ensure complete dispersion and dissolution of the solid material, and then cooling it to room temperature for later use.

[0040] By adopting the above technical solution and the above pre-preparation process, solid materials such as p-hydroxyacetophenone and hydroxyphenylpropionamide benzoic acid can be better dissolved, so that the two substances can be more uniformly dispersed in the liquid.

[0041] Thirdly, the facial mask provided in this application adopts the following technical solution:

[0042] A face mask comprising a mask sheet and a whitening liquid that softens the stratum corneum.

[0043] By adopting the above technical solution, applying a mask soaked in the liquid to the face for a period of time allows the substances in the liquid to penetrate the skin more comprehensively and deeply, thereby enhancing the effects of each substance on the skin.

[0044] In summary, this application includes at least one of the following beneficial technical effects:

[0045] 1. Through the synergistic effect of glycerin, sodium hyaluronate, sodium polyglutamate, and arginine, it promotes the exfoliation of the skin's keratinocytes, which can reduce damage to sensitive skin, making it suitable for people with sensitive skin. It can also be used daily, providing a gentler way to soften and remove dead skin cells in daily skincare.

[0046] 2. Skin probiotics, oat extract, and troxerutin work synergistically to better improve inflammation caused by excessive keratinization, providing a gentler exfoliation treatment;

[0047] 3. Papain can promote the shedding of skin keratin. By adding a small amount of papain, the keratin can be softened and the shedding of keratin can be accelerated during the replacement of dead keratinocytes with new cells, thereby enhancing the exfoliation effect while being as gentle as possible.

[0104] III. Performance Testing

[0105] 1) pH measurement: The pH values ​​of the solutions prepared in Examples 1-13 and Comparative Examples 1-4 were tested by using moistened pH test paper. The test results are shown in Table 6.

[0106] 2) Stability test: The liquids prepared in Examples 1-13 and Comparative Examples 1-4 were respectively encapsulated in centrifuge tubes and centrifuged in a centrifuge at a speed of 3000 r / min for 30 min. The test results are shown in Table 6.

[0107] 3) Skin exfoliation and brightening effect test:

[0108] Subjects: Female volunteers aged 28-32 were selected and randomly divided into 17 groups of 5 people each;

[0109] Exfoliation effect test method: Subjects in groups 1-17 used the liquid masks prepared in Examples 1-13 and Comparative Examples 1-4 on their faces, once every 2 days. After 2 days, 6 days and 10 days, the skin condition of the subjects' faces was tested using the VISIA facial image analyzer. The test results are shown in Table 6.

[0110] Brightening effect test method: Subjects in groups 1-17 used the liquid masks prepared in Examples 1-13 and Comparative Examples 1-4 on their faces, once every 2 days. After 2, 6 and 10 days, the skin color difference test probe was used to test the increase rate of skin brightness ITA° before and after the subjects. ITA° is the individual skin type angle. The larger the ITA° value, the brighter the skin; conversely, the darker the skin, the more dull the skin. The test results are shown in Table 6.

[0111] 4) Anti-allergy effect test method:

[0112] Healthy mice weighing 18–22g were randomly divided into 17 groups of 10 mice each. The back hair of the animals was removed with 1% sodium sulfide, and the area of ​​the hairless skin area was 1.5 × 1.5 cm.

[0113] The hairless areas on the backs of animals in groups 1-17 were locally treated with the solutions (1 ml / kg) prepared in Examples 1-13 and Comparative Examples 1-4, with physiological saline as a negative control sample. The treatment was carried out for 5 consecutive days. 30 minutes after the last application, mice in each group were injected with dextran 0.95 mg / kg via the tail vein.

[0114] The itch was indicated by the mice scratching their heads with their forepaws, scratching their trunks with their hindaws, and biting their bodies. The number of times the mice itch within 30 minutes was recorded, and the itch inhibition rate was calculated according to the following formula. The test results are shown in Table 7.

[0115] Calculation formula: Itching inhibition rate = (Number of itching events in the negative control group - Number of itching events in the sample group) ÷ Number of itching events in the negative control group * 100%.

[0116] Table 6:

[0117]

[0118] IV. Results Analysis and Summary

[0119] Based on Examples 1-13, Comparative Examples 1-4, and Table 6, it can be seen that the pH values ​​of Examples 1-13 are all between 5.5 and 7. A pH range of 5.5-7 is considered suitable for human skin. Too high a pH can easily cause skin aging, while too low a pH can easily cause skin sensitivity. Therefore, the pH of the solution in this application is suitable for human skin care. Because L-arginine has a certain pH-regulating effect, and Comparative Example 2 lacks arginine for pH regulation, the pH value of the solution is too low.

[0120] As shown in Table 6, no stratification occurred in Examples 1-13, indicating that the material solution of this application has good stability. However, stratification occurred in Comparative Example 4, which was due to the temperature inside the emulsifying pot not being lowered to 42-47℃.

[0121] As can be seen from Examples 1-3 and Table 6, the proportions of each component in Examples 1-3 are different. As shown in Table 6, the average skin roughness reduction rate of Examples 1-3 increases with the increase of usage time, while the average skin roughness reduction rate of the subjects in Example 2 is higher than that of Examples 1 and 3 at each time period; the average increase rate of ITA° value of Examples 1-3 increases with the increase of usage time, while the average increase rate of ITA° value of the subjects in Example 2 is higher than that of Examples 1 and 3; and the average pruritus inhibition rate of Example 2 is higher than that of Examples 1 and 3.

[0122] Furthermore, comparing Comparative Examples 1 and 2, Comparative Example 1 lacked sodium hyaluronate, and Comparative Example 2 lacked arginine. Table 6 shows that the average reduction rate of skin roughness at each time point for subjects in Comparative Examples 1 and 2 was significantly lower than that in Example 2; the average increase rate of ITA° values ​​at each time point for subjects in Comparative Examples 1 and 2 was also somewhat lower than that in Example 2. Therefore, it can be concluded that the synergistic effect between sodium hyaluronate and arginine significantly enhances the exfoliation effect and also has a good effect on brightening the skin.

[0123] As can be seen from the above, the component content of Example 2 has a better exfoliating and brightening effect on the skin, and the component content of Example 2 has a better anti-allergic effect on the skin. Therefore, the liquid prepared in Example 2 can achieve better exfoliation and whitening effects, while being gentler on the skin, making it more suitable for people with sensitive skin and those who need to perform daily exfoliation care.

[0124] Based on Examples 2, 4-5, and Table 6, it can be seen that the content of the whitening agent components in Examples 4-5 differs from that in Example 2. Table 6 shows that the average rate of reduction in skin roughness at each time period was lower in Examples 4-5 compared to Example 2; the average rate of increase in ITA° values ​​at each time period was also lower in Examples 4-5 compared to Example 2. Therefore, the content of the whitening agent components in Example 2 provides better exfoliation and brightening effects on the skin.

[0125] Furthermore, in Comparative Example 3, where the papain in the whitening agent of Comparative Example 2 was replaced with sodium polyglutamate in equal amounts, the average rate of reduction in skin roughness and the average rate of increase in ITA° value at each time point in Comparative Example 3 were significantly lower than those in Example 2. This indicates that the addition of papain has a better exfoliating and brightening effect on the skin. Combining Examples 2, Examples 6-7, and Table 6, it can be seen that the content of each component of the skin probiotics in Examples 6-7 differs from that in Example 2. Table 6 shows that the average rate of reduction in skin roughness and the average rate of increase in ITA° value at each time point in Examples 6-7 did not change significantly compared to Example 2, but the average itching inhibition rate in Examples 6-7 was significantly lower than that in Example 2. This indicates that the component content of the skin probiotics in Example 2 has a better anti-allergic effect on the skin.

[0126] Based on Examples 2, 8-9, and Table 6, it can be seen that the content of each component of the anti-allergy agent in Examples 8-9 differs from that in Example 2. Table 6 shows that the average reduction rate of skin roughness and the average increase rate of ITA° value in subjects at each time period in Examples 8-9 show smaller changes compared to Example 2, but the average pruritus inhibition rate in Examples 8-9 is significantly lower than that in Example 2. Therefore, it can be concluded that the component content of the anti-allergy agent in Example 2 has a better anti-allergic effect on the skin.

[0127] Based on Examples 2, 12-13, and Table 6, it can be seen that the temperatures in the emulsification pot when adding phases B / C / D / E / F in Examples 12-13 were different from those in Example 2. Table 6 shows that the average rate of reduction in skin roughness for subjects in Example 2 at each time period was higher than that in Examples 12-13; the average rate of increase in ITA° values ​​for subjects in Example 2 at each time period was higher than that in Examples 12-13; and the average pruritus inhibition rate in Example 2 was higher than that in Examples 12-13.

[0128] Furthermore, in Comparative Example 5, the temperature in the emulsification pot when the B / C / D / E / F phase materials were added was different from that in Example 2. The average rate of reduction in skin roughness, the average rate of increase in ITA° value, and the average rate of pruritus inhibition of the subjects in Comparative Example 5 at each time period were significantly lower than those in Example 2.

[0129] Therefore, it can be seen that the temperature in the emulsification pot when adding B / C / D / E / F phase materials is 42-47℃. The prepared liquid can achieve better exfoliation and whitening effects, while being gentler on the skin. The best effect is achieved when the temperature is stable at 45℃.

[0130] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made to the products, methods and principles of this application should be covered within the scope of protection of this application.
