Description

Technical Field

[0001] This invention belongs to the field of cosmetic technology, specifically relating to an acne-removing shower gel containing tea seed water and its preparation method. Background Technology

[0002] With social progress and economic development, people's living standards are constantly improving. Nowadays, in addition to paying attention to facial skin care, people are also paying more attention to the care and maintenance of their entire body's skin, and bath products have become one of the main products for people to care for their entire body's skin.

[0003] Currently, 99% of commercially available bath products are traditional shower gels, mostly based on water and surfactants. The advantages of traditional shower gels are that they lather easily and produce rich foam; the disadvantages are that they leave a slippery residue that is difficult to rinse off, causing dryness, allergies, and redness. Especially in autumn and winter, when skin is prone to dehydration and dryness, they cannot provide adequate moisturizing, leading to itching, redness, and sebum loss. Furthermore, for people with acne-prone skin, traditional shower gels often fail to effectively address acne problems and may even worsen acne due to incomplete cleansing or irritating ingredients. Therefore, the goal is to develop a product that cleanses, effectively treats acne, and moisturizes, addressing the aforementioned problems of existing commercially available shower gels to meet people's higher demands for comprehensive skin care and maintenance.

[0004] Tea seed cake (tea seed meal), as a traditional natural washing and care ingredient, is rich in tea saponins, proteins, and other active ingredients, possessing excellent cleansing, stain removal, antibacterial, antipruritic, and skin-nourishing effects. Tea saponins in tea seed cake are a natural nonionic surfactant with excellent emulsifying, dispersing, foaming, and wetting functions, and also have anti-inflammatory, antibacterial, analgesic, and anti-penetration pharmacological effects. It is non-irritating to the skin and safe and environmentally friendly. Tea seed cake aqueous extract, rich in tea saponins, proteins, polysaccharides, and trace elements, has natural cleansing, oil-controlling, and acne-inhibiting effects, making it an ideal base for acne-fighting shower gels. To impart complex effects such as acne-fighting, cleansing, and barrier repair to shower gels, it is usually necessary to introduce some key ingredients. However, the introduction of each type of ingredient will have a certain impact on the stability of the system. For example, anionic surfactants are the core source of the cleansing power of shower gels, while cationic guar gum is an excellent skin conditioning agent that can repair damaged skin barriers. However, cationic guar gum and anionic surfactant systems have inherent charge conflicts. Salicylic acid, a conditioning agent, is the core active ingredient for acne treatment, but its stability is highly dependent on the pH environment and cannot be directly matched with the alkaline system of tea seed water, etc.

[0005] Therefore, when using tea seed water as the base of a shower gel system, how to ensure its own stability, fully utilize its efficacy, and coexist with other key components (such as conditioning agents) while achieving excellent cleansing, acne removal, and barrier repair effects has become a core technical problem that needs to be solved in the development of acne-removing shower gels containing tea seed water. Summary of the Invention

[0006] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes an acne-removing body wash containing tea seed cake water and its preparation method. This acne-removing body wash uses tea seed cake water as the active ingredient. Through optimization and adjustment of the formula components and ratios, the compatibility issues between tea seed cake water and anionic surfactants, cationic conditioners, and active ingredients are resolved. The system exhibits excellent stability and simultaneously possesses multiple functions including cleansing, acne removal, moisturizing, and barrier repair, better meeting the skincare needs of acne-prone skin.

[0007] This invention provides an acne-removing body wash containing tea seed oil.

[0008] Specifically, an acne-fighting body wash containing tea seed oil contains the following components in parts by weight: Phase A: 45-75 parts tea seed oil, 0.05-0.3 parts chelating agent, 0.05-0.5 parts primary conditioning agent, and 0.1-0.5 parts thickener; Phase B: 22-32 parts surfactant, 0.1-0.5 parts primary humectant, and 0.05-0.3 parts camellia seed oil; Phase C: 3-10 parts of the second moisturizer, 0.2-1.0 parts of the second conditioning agent; Phase D: 0.3-1.5 parts of the third conditioning agent, 0.1-1.0 parts of rosemary extract, and 0.5-2.0 parts of tea extract; The first conditioning agent is cationic guar gum, the second conditioning agent is salicylic acid and / or azelaic acid, and the third conditioning agent is Centella asiatica extract; the first moisturizer is allantoin; and the second moisturizer is at least two of panthenol, glycerin, betaine, and sodium PCA. The surfactants include sodium lauryl ether sulfate, cocamidopropyl betaine, sodium lauroyl sarcosinate, and cocoyl monoethanolamide.

[0009] In some embodiments of the present invention, the acne-removing shower gel containing tea seed water comprises the following components by weight: Phase A: 55-75 parts tea seed oil, 0.05-0.3 parts chelating agent, 0.05-0.2 parts primary conditioning agent, and 0.2-0.5 parts thickener; Phase B: 23-30 parts surfactant, 0.2-0.5 parts primary humectant, 0.1-0.2 parts camellia seed oil; Phase C: 3-6 parts of the second moisturizer, 0.2-0.8 parts of the second conditioning agent; Phase D: 0.4-1.2 parts of the third conditioning agent, 0.2-0.8 parts of rosemary extract, and 0.8-1.5 parts of tea extract.

[0010] In some embodiments of the present invention, the chelating agent is one or more of disodium ethylenediaminetetraacetate, tetrasodium ethylenediaminetetraacetate, and sodium citrate.

[0011] In some embodiments of the present invention, the thickener is one or more of acrylate / C10-30 alkanol acrylate crosspolymer, xanthan gum, and hydroxyethyl cellulose.

[0012] In some embodiments of the present invention, the mass ratio of sodium lauryl ether sulfate to cocamidopropyl betaine, sodium lauroyl sarcosinate, and cocoyl monoethanolamide is (6-9):(2-4):(1-3):(1-2); preferably, the mass ratio of sodium lauryl ether sulfate to cocamidopropyl betaine, sodium lauroyl sarcosinate, and cocoyl monoethanolamide is (6-9):(2-3):(1-3):(1-1.5).

[0013] In some embodiments of the present invention, the D phase further includes a preservative. The preservative includes one or more of phenoxyethanol, sodium benzoate, potassium sorbate, ethylhexylglycerin, p-hydroxyacetophenone, hexanediol, and pentanediol.

[0014] In some embodiments of the present invention, the preservative is 0.5-3 parts by weight. The use of the preservative strictly follows the "Cosmetic Safety Technical Specifications (2015 Edition)".

[0015] In some embodiments of the present invention, the D phase further contains 0.05-1.5 parts of fragrance by weight, and the fragrance can be adjusted according to needs to meet different usage preferences.

[0016] In some embodiments of the present invention, the camellia seed oil is a product obtained by supercritical CO2 extraction of camellia seeds; the tea bran water is an extract obtained by water extraction of tea bran obtained after supercritical CO2 extraction of camellia seed oil from camellia seeds. Supercritical CO2 extraction technology can preserve the integrity of active ingredients and improve the quality and stability of the product. In practical production applications, camellia seed raw materials can be pretreated, then supercritical CO2 extraction can be performed to obtain camellia seed oil, and the remaining tea bran can be further water-extracted to obtain the corresponding tea bran water. Alternatively, camellia seed oil and tea bran extracted by supercritical CO2 can be purchased directly, and the tea bran can be water-extracted to obtain tea bran water. Regardless of the method used, as long as the content of tea saponin in the tea bran is greater than 13%, and the content of tea saponin in the tea bran water added to the skin cleansing composition is 5.0%-10.0% (w / w) (preferably 5.0%-8.0%) through dilution or concentration, good efficacy can be achieved.

[0017] In some embodiments of the present invention, the pH value of the shower gel is 5.0-6.5, preferably 5.8-6.2.

[0018] The present invention also provides a method for preparing the above-mentioned acne-removing shower gel containing tea seed water.

[0019] Specifically, the preparation method of the above-mentioned acne-removing shower gel containing tea seed oil includes the following steps: Weigh out the tea seed water, add the components of phase A, and stir until dissolved; then heat up and add the components of phase B, stirring until dissolved; then add the components of phase C, stirring until dissolved; finally add the components of phase D, stir, and discharge.

[0020] In some embodiments of the present invention, after adding the components of phase C and / or phase D, a pH adjustment process is further included to adjust the system pH to 5.0-6.5. This step satisfies the stability requirements of acne-fighting active ingredients such as salicylic acid and is compatible with the slightly acidic environment of the skin, reducing irritation to the skin barrier. The pH is adjusted using a pH adjuster, which includes one or more of sodium hydroxide, potassium hydroxide, citric acid, and sodium citrate. In actual production, the amount of pH adjuster added is adjusted according to the actual pH of the system to adjust the system pH to 5.0-6.5; this amount is not included in the amounts of the aforementioned phase components.

[0021] More specifically, the preparation method of the above-mentioned acne-removing shower gel containing tea seed oil includes the following steps: (1) Weigh out the tea seed water, add the components of phase A in sequence, stir until dissolved, and obtain mixture A; (2) After heating to 70-80℃, add the components of phase B, stir until dissolved, and keep warm for 5-30 minutes to obtain mixture B; (3) After the heat preservation is completed, the temperature is lowered to 50-60℃, the components of phase C are added, and the mixture is stirred until dissolved to obtain mixture C; (4) After the temperature drops to below 44℃, add the D phase components, stir, cool down, adjust the pH value to 5.0-6.5, and discharge.

[0022] Compared with the prior art, the beneficial effects of the present invention are as follows: (1) The acne-removing shower gel containing tea seed water provided by the present invention is divided into phases A, B, C, and D. By controlling the selection, dosage, and timing of addition of conditioning agents and other components, and with the addition of surfactants, the tea seed water matrix can ensure its own stability and coexist with other key components (such as conditioning agents), which significantly improves the stability of the system. Specifically, the chelating agent in phase A complexes with the metal ions in the tea seed water in the first step, effectively inhibiting the hydrolysis of tea saponins and ensuring the long-term stability of the tea seed water itself; the first conditioning agent is added before the thickener, so that the first conditioning agent is more evenly dispersed in the system. When it comes into contact with the surfactant with the opposite charge in phase B, it is not easy to flocculate, thus achieving the stable coexistence of the first conditioning agent and the surfactant. Phases C and D are added in the later stages, which not only ensures that the temperature-sensitive active ingredients such as salicylic acid will not be damaged by high temperature, but also further maintains the stability of the system, so that the final product system is stable and uniform, and at the same time has multiple functions of cleansing, acne removal, moisturizing, and barrier repair.

[0023] (2) In the acne-removing body wash containing tea seed oil provided by the present invention, the tea saponin in the tea seed oil, as a natural nonionic surfactant, is combined with the anionic surfactant in phase B to effectively remove excess oil while gently cleansing. At the same time, the tea saponin, the second conditioning agent in phase C, rosemary extract, tea extract, and the third conditioning agent in phase D each play a role from different aspects, working together to effectively inhibit acne. In addition, the acne-removing body wash provided by the present invention has outstanding moisturizing and barrier repair effects. Camellia seed oil can form a natural moisturizing film on the skin surface, and the second moisturizer in phase C can provide a long-lasting moisturizing effect. The two work together to keep the skin moisturized after cleansing; while the first conditioning agent in phase A adheres to the skin surface, which can reduce the irritation caused by surfactants and help maintain the health of the skin barrier.

[0024] (3) The shower gel provided by this invention uses natural tea seed water and camellia seed oil as core ingredients. Through scientific formulation of surfactants and conditioners, it achieves multiple effects of gentle cleansing, acne removal, and nourishment. The preparation method provided by this invention is simple to operate, has mild process conditions, is easy to control, and is suitable for large-scale industrial production.

[0037] Comparative Example 1 The difference between this comparative example and Example 1 is that the components and amounts are exactly the same, but the first conditioning agent, cationic guar gum, and the third conditioning agent, Centella asiatica extract, are combined with the second conditioning agent and are all used as C-phase components. In addition, because cationic guar gum dissolves more slowly at low temperatures, the stirring and dissolving time in step (3) will be longer than in Example 1, while the rest of the preparation process is the same as in Example 1.

[0038] Comparative Example 2 The difference between this comparative example and Example 1 is that the components and amounts are exactly the same, but the second conditioner, salicylic acid, and the third conditioner, Centella asiatica extract, are combined with the first conditioner and are all used as components of phase A. The preparation process is the same as in Example 1.

[0039] Comparative Example 3 The difference between this comparative example and Example 1 is that the components and amounts are exactly the same, but the third conditioning agent, Centella asiatica extract, and the second conditioning agent, salicylic acid, are combined and both are used as phase C components; the second moisturizing agents, panthenol, glycerin, betaine, and sodium PCA, are combined with the first moisturizing agent, allantoin, and are used as phase B components. The preparation process is the same as in Example 1.

[0040] Comparative Example 4 The difference between this comparative example and Example 1 is that the components of phase D do not contain rosemary extract, and the amount of tea extract is increased to 1.7 parts. The remaining components, amounts, and preparation process are the same as in Example 1.

[0041] Comparative Example 5 The difference between this comparative example and Example 1 is that the components of phase D do not contain tea extract, and the amount of rosemary extract is increased to 1.7 parts. The remaining components, amounts, and preparation process are the same as in Example 1.

[0042] Comparative Example 6 The difference between this comparative example and Example 1 is that the tea seed water in phase A is replaced with deionized water, while the remaining components, amounts, and preparation process are the same as in Example 1.

[0043] Product effectiveness test (1) Inhibitory effect on Propionibacterium acnes The inhibitory effect of the acne-removing shower gels provided in Examples 1-3 or Comparative Examples 1-6 on Propionibacterium acnes (ATCC 6919) was tested according to QB / T 2738-2023 "Evaluation Method for Antibacterial and Bacteriostatic Effects of Daily Chemical Products". The test results are shown in Table 4.

[0044] Table 4

[0045] As shown in Table 4, the acne-removing body wash provided in the embodiments of the present invention all achieved an inhibition rate of over 99.7% against Propionibacterium acnes, with Example 2 exhibiting the best inhibition effect at 99.92%. The acne-removing body wash prepared in the embodiments of the present invention has a very strong inhibitory effect on Propionibacterium acnes, demonstrating outstanding acne-removing efficacy. However, Comparative Examples 1, 2, and 3, which adjusted the components of phases A, B, C, and D (essentially the order of addition), although having the same overall components and dosages as Example 1, showed a lower inhibition rate against Propionibacterium acnes than Example 1, with a significant decrease. In particular, Comparative Example 3, by combining panthenol, sodium PCA, and the first moisturizing agent allantoin as phase B components, severely affected the activity of the ingredients, thereby reducing the inhibitory effect on Propionibacterium acnes. This demonstrates that the phase-separated addition and controlled timing of component addition process of the present invention not only improves system stability but also better preserves the antibacterial and acne-removing activities of each active ingredient, ensuring the efficacy of the final product. After removing rosemary extract or tea extract from Comparative Examples 4 and 5, respectively, the inhibition rate dropped to below 95%, indicating that the combined use of the two extracts can exert a synergistic antibacterial effect, which is significantly better than the use of a single ingredient alone. In Comparative Example 6, after replacing the tea seed water with deionized water, the inhibition rate plummeted to 71.35%, far lower than all experimental groups containing tea seed water. This fully demonstrates that tea seed water itself is the core source of the antibacterial and acne-removing efficacy of this invention. The tea saponins in the tea seed water, combined with other active ingredients, can achieve excellent synergistic effects, significantly enhancing the inhibitory ability against Propionibacterium acnes and ensuring the product's acne-removing effect.

[0046] (2) Cleanliness and usability evaluation Fifteen volunteers with back acne were randomly selected. Each volunteer used the acne-removing body washes from Examples 1-3 and Comparative Examples 1-6, using the same method. Volunteers rated the richness of lather, cleansing power, ease of rinsing, and the feeling of washing their backs based on their personal experience. A maximum score of 10 points was used, with higher scores indicating better effectiveness and a better user experience. The average scores from the 15 volunteers regarding their experience with the cleansing products provided in the examples and comparative examples were then calculated. The evaluation results are shown in Table 5.

[0047] Table 5 Cleanliness and usability evaluation form

[0048] As shown in Table 5, the acne-removing body wash containing tea seed cake water prepared in Examples 1-3 of this invention scored above 9.0 points in all indicators, indicating an excellent overall user experience. In Comparative Example 6, after replacing the tea seed cake water with deionized water, the user experience scores decreased significantly, with foam richness at only 7.5 points and cleansing performance at only 7.9 points. This demonstrates that the natural tea saponins in the tea seed cake water significantly enhance the product's cleansing and foaming abilities, resulting in a better user experience. After adjusting the components of phases A, B, C, and D in Comparative Examples 1-3 (essentially the order of addition), their overall user experience was slightly worse than that of Example 1. This shows that phase-separate addition and controlling the timing of component addition allow each ingredient, especially the conditioning and moisturizing ingredients, to function better, improving comfort while maintaining cleansing power. The products provided in Comparative Examples 4 and 5 had a similar user experience to Example 1, with only slight differences in the back washing experience. This indicates that the combination of rosemary extract and tea extract can better soothe discomfort in acne-prone areas.

[0049] (3) Stability test The acne-removing body washes provided in Examples 1-3 or Comparative Examples 1-6 were placed in an environment of 60°C and 75% relative humidity for 3 months. Samples were taken at 1 month, 2 months and 3 months to observe the appearance, texture and layering of the samples. The test results are shown in Table 6.

[0050] Table 6 Stability Test Results

[0051] As shown in Table 6, the acne-removing body washes provided in Examples 1-3 of this invention showed no abnormal changes in appearance or texture, nor did they exhibit stratification, even after being stored for 3 months using accelerated storage. This invention, through phase-separated feeding and controlling the order of component addition, can solve the problem of poor stability in acne-removing body wash systems based on tea seed water, effectively ensuring the long-term stability of the product system. Comparative Examples 1 and 2, after adjusting the components of phases A, B, C, and D (essentially the order of addition), showed slight stratification after only 1 month of storage, and severe stratification after 3 months, with the system stability completely failing to meet normal storage and sales requirements. Comparative Example 3 also only maintained no abnormalities for 1 month, and after 3 months, significant stratification and a coarser texture appeared. Comparative Examples 4 and 5, however, only adjusted the amounts of rosemary extract and tea extract without changing the order of component addition, thus maintaining good product stability. Comparative Example 6, even after replacing tea seed water with deionized water, still showed stratification, indicating that tea seed water itself has a complex composition. The phase-separated feeding process of this invention can specifically solve the problem of poor stability in tea seed water systems.

[0052] Tea saponins in tea bran water have excellent cleansing, stain-removing, and antibacterial effects, effectively removing dirt, excess oil, and acne-causing factors such as Propionibacterium acnes from the skin surface, reducing acne from its root cause. Simultaneously, conditioning agents such as cationic guar gum, salicylic acid, azelaic acid, and Centella asiatica extract can penetrate deep into pores, regulate sebum secretion, promote skin metabolism, accelerate acne reduction, and prevent acne recurrence. Because the complexity of the components in tea bran water is far greater than that of ordinary water-based matrices, ensuring the compatibility of multiple acne-fighting components within a complex system, and maintaining a stable and homogeneous final product system, is one of the challenges this invention needs to address. Research has found that by selecting and classifying conditioning agents and adding them to the system at the timing determined by this invention, the compatibility issues of multiple active components in the tea bran water matrix can be effectively solved. This avoids problems such as stratification and flocculation during preparation and storage that affect system stability, while ensuring that each active ingredient can function stably without losing its efficacy due to interactions between components. The finished product remains uniform after being stored at 60℃ for 3 months, without any issues such as stratification, precipitation, or discoloration. The system exhibits excellent stability and can meet the needs of mass production, normal storage, and sales.

[0053] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of this patent should be determined by the appended claims.
