Description

Technical Field

[0001] This invention relates to the field of hair care, and in particular to a plant-based anti-dandruff composition, its preparation method, and its application. Background Technology

[0002] In the shampoo market, anti-dandruff and anti-itch products dominate, ranking first in demand. Statistics show that in 2023, the annual consumption of anti-dandruff shampoo in China exceeded 30 billion yuan, occupying a significant share of the overall shampoo market and demonstrating a large and stable market foundation.

[0003] Currently, commonly used anti-dandruff agents in shampoos and conditioners are mainly composed of chemically synthesized raw materials, including zinc pyrithione (ZPT), piroctone olamine (OCT), selenium disulfide, clomiphene (Ganbaosu), and hexamididine dihydroxyethyl sulfonate (HD). These ingredients achieve their anti-dandruff and anti-itch effects by inhibiting the growth and reproduction of Malassezia, exerting anti-inflammatory effects, or regulating scalp keratin metabolism, and are therefore widely used in various shampoos. It is worth noting that ZPT, which once held approximately 30% of the anti-dandruff agent market share, has significant potential safety risks, leading to the widespread use of alternative ingredients such as OCT and Ganbaosu.

[0004] While these chemically synthesized anti-dandruff agents demonstrate outstanding effectiveness in controlling dandruff, quickly inhibiting Malassezia, and alleviating dandruff and itching, they present several significant challenges in practical application. Firstly, some ingredients are irritating, and long-term use may damage the scalp barrier, leading to scalp sensitivity, dryness, and even worsening dandruff. Some ingredients also possess potential toxicity, posing risks to human health. Secondly, some anti-dandruff agents exhibit poor stability within the product system, easily discoloring due to factors such as light and temperature, affecting the product's appearance. Furthermore, the relatively high cost of alternative ingredients like OCT increases manufacturing costs, hindering the development of cost-effective products.

[0005] Regarding the aforementioned technologies, the inventors believe that it is necessary to develop a plant-based dandruff removal composition that is relatively environmentally friendly, less irritating, and effective in removing dandruff, based on plant-based raw materials. Summary of the Invention

[0006] To address the technical deficiencies of existing technologies, this application provides a plant-based desquamation composition, its preparation method, and its application.

[0007] In a first aspect, this application provides a plant-based anti-dandruff composition, which adopts the following technical solution:

[0008] A plant-based anti-dandruff composition comprising, by weight parts:

[0009] The product contains 55-80 parts of functional components, 15-40 parts of clove extract, and 1-5 parts of antibacterial agent; the functional components are plant extracts, and the raw materials for the plant extracts include chrysanthemum, burdock seed, and white willow bark.

[0010] By adopting the above technical solutions, the flavonoids in chrysanthemum can inhibit the expression of inflammatory factors and repair the scalp barrier; arctiin from burdock seeds can inhibit excessive sebum secretion; and salicin from white willow bark can regulate keratin metabolism. The three form a basic synergy of "anti-inflammatory, oil control, and keratin regulation," reducing the conditions for dandruff growth from the root. Eugenol, purified from clove extract through steam distillation, alkali dissolution, and acid precipitation, can destroy the cell membrane of pathogenic bacteria to achieve precise antibacterial action. It forms a dual effect of "environmental optimization + direct sterilization" with the functional components, significantly improving dandruff removal efficiency. After the antibacterial agent is combined with the solvent, it can help strengthen the antibacterial effect and at the same time alleviate the slight dryness that may be caused by salicylic acid in white willow bark, forming a triple synergy with plant components and clove extract. The scientifically formulated ratio has been verified by orthogonal experiments. The high proportion of functional components ensures that the basic efficacy is fully exerted. The amount of clove extract balances antibacterial concentration and safety, while the low proportion of antibacterial agent reduces the burden on the scalp. The three work together to solve the shortcomings of traditional anti-dandruff products, such as slow effect, easy recurrence, and strong irritation, and achieve the effects of rapid dandruff removal, immediate itch relief, and long-term scalp stability.

[0011] Preferably, the mass ratio of chrysanthemum, burdock, and white willow bark in the raw materials of the plant extract is (2-3):(1-2):(1-2).

[0012] By adopting the above technical solution and limiting the specific mass ratio of the three components, the efficacy of each ingredient can be maximized: chrysanthemum has the highest proportion, ensuring the dominant anti-inflammatory and soothing effect; the proportion of burdock seed and white willow bark is balanced, taking into account both oil regulation and keratin metabolism, avoiding scalp irritation or insufficient efficacy caused by excessive amount of a single ingredient, and further optimizing the gentleness and effectiveness of dandruff removal.

[0013] Preferably, the functional component is prepared by the following method:

[0014] S1: Weigh chrysanthemum, burdock seed, and white willow bark, and crush the burdock seed and white willow bark to 10-40 mesh. Add 8 times the weight of the raw materials in ethanol, soak and heat, then perform solid-liquid separation and collect the liquid.

[0015] S2: Add 6 times the mass of ethanol to the raw material and heat, then perform solid-liquid separation and collect the liquid;

[0016] S3: Mix the liquids collected in steps S1 and S2 together, let stand and collect the supernatant, concentrate the supernatant, add 1 to 5 times the mass of the concentrated supernatant of butanediol and 0.5 to 2 times the mass of the concentrated supernatant of purified water, stir evenly to obtain the functional component.

[0017] By adopting the above technical solution and using the "double ethanol extraction" process, compared with single extraction, the active ingredients (such as flavonoids, arctiin, salicin, etc.) in the raw materials can be dissolved more fully, thus improving the yield of active ingredients. Subsequently, butylene glycol and purified water are added for dilution and preparation. On the one hand, butylene glycol can enhance the stability of active ingredients and prevent their oxidation and inactivation. On the other hand, it can improve the solubility of functional components, making them easier to mix with clove extract and antibacterial agents, avoiding stratification or precipitation, and improving the homogeneity of the composition.

[0018] Preferably, the heating temperature in steps S1 and S2 of the preparation method of the functional component is 75-80°C, and the heating time is 1.5-2 hours. The temperature needs to be lowered to 35°C before solid-liquid separation in steps S1 and S2.

[0019] By adopting the above technical solution and limiting the heating temperature to 75-80℃, the dissolution efficiency of ethanol on active ingredients can be guaranteed, while avoiding the decomposition of active ingredients caused by high temperature (such as the easy oxidation and inactivation of flavonoids at high temperature); the heating time of 1.5-2 hours can ensure the full dissolution of active ingredients, while avoiding the increase of impurities due to excessive extraction time; cooling to 35℃ before solid-liquid separation can reduce ethanol volatilization, reduce production costs, and at the same time avoid the denaturation of active ingredients due to temperature fluctuations during solid-liquid separation at high temperature, further ensuring the efficacy stability of functional components.

[0020] Preferably, the clove extract is prepared by the following method:

[0021] S1: Crush clove buds, add purified water, soak and heat to 100℃ and keep boiling. Collect the volatile components with a condenser. After the collected volatile components stand and separate into layers, take the upper oily substance B1.

[0022] S2: Add 10wt% sodium hydroxide solution to oily substance B1, stir thoroughly until it separates into layers, and take out the lower aqueous phase substance B2;

[0023] S3: Add dilute hydrochloric acid to aqueous substance B2 until the pH of the solution is 2-3. After standing and separating the layers, remove the lower acidic aqueous solution B3 to obtain crude extract B4.

[0024] S4: Crude extract B4 was washed with distilled water to obtain clove extract.

[0025] By adopting the above technical solution and using the process route of "steam distillation ~ alkali dissolution ~ acid precipitation ~ washing", the core antibacterial components such as eugenol in cloves are extracted in a targeted manner: steam distillation can efficiently separate volatile eugenol and avoid organic solvent residue; the alkali dissolution step can convert eugenol into water-soluble sodium phenolate, realizing the separation from oil phase impurities; the acid precipitation step reduces sodium phenolate to eugenol, significantly improving purity; finally, washing with distilled water further removes residual salt and water-soluble impurities, resulting in high-purity clove extract with stronger antibacterial activity, which can accurately inhibit pathogenic bacteria such as Malassezia that cause dandruff, and there is no organic solvent residue, improving the safety of the composition.

[0026] Preferably, the crude extract B4 in step S4 is further subjected to vacuum distillation after being washed with distilled water.

[0027] By adopting the above technical solution and adding a vacuum distillation step, the residual trace amounts of moisture and volatile impurities in crude extract B4 can be further removed, thereby increasing the concentration and purity of clove extract and enhancing its antibacterial activity. At the same time, vacuum distillation is carried out at low temperatures, which can prevent the decomposition of active ingredients such as eugenol due to high temperatures, ensuring the efficacy stability of the extract and making the synergistic antibacterial effect more significant when it is subsequently compounded with functional components and antibacterial agents.

[0028] Preferably, the antibacterial agent comprises acetyl dipeptide-3 and a solvent.

[0029] By adopting the above technical solution, acetyl dipeptide-3 is selected as the core ingredient of the antibacterial agent. It has a targeted antibacterial effect and can specifically inhibit the growth and reproduction of Malassezia. Compared with traditional chemical antibacterial agents, it is less irritating and less likely to cause scalp allergies or dryness. At the same time, acetyl dipeptide-3 works synergistically with functional components and clove extract to form a combination of "plant active ingredients + bioactive peptide antibacterial agents". This combination not only exerts the mild anti-inflammatory and oil-controlling effects of plant ingredients, but also utilizes the highly effective antibacterial effect of bioactive peptides to achieve a combination of short-term dandruff removal and long-term recurrence prevention.

[0030] Preferably, the solvent is butanediol and water.

[0031] By adopting the above technical solution, butylene glycol and water are selected as solvents for the antibacterial agent. Butylene glycol has good solubility, which can fully dissolve acetyl dipeptide-3 and prevent crystallization. At the same time, butylene glycol has a moisturizing effect and can relieve scalp dryness. Water, as a diluent, can adjust the concentration of the antibacterial agent, making it more compatible with functional components and clove extract, ensuring the homogeneity and stability of the entire composition system, and avoiding problems such as layering and precipitation during use.

[0032] Secondly, this application provides a method for preparing a plant-based anti-dandruff composition, using the following technical solution:

[0033] A method for preparing a plant-based anti-dandruff composition includes the following steps:

[0034] The functional components, clove extract, and antibacterial agent were weighed separately, and the functional components, clove extract, and antibacterial agent were thoroughly mixed to obtain a plant-based anti-dandruff composition.

[0035] By adopting the above technical solution, the preparation method is simple and easy to implement, and is suitable for large-scale industrial production.

[0036] Preferably, this application also includes the use of the above-mentioned plant-based anti-dandruff composition in the preparation of shampoo and hair care products.

[0037] In summary, this application has the following beneficial effects:

[0038] 1. Each component of the composition in this application targets the core aspects of dandruff growth, providing multi-dimensional efficacy support. Among the functional components, the flavonoids of chrysanthemum can inhibit the expression of inflammatory factors such as TNF-α and IL-6, block the transmission of scalp inflammatory signals, and simultaneously clear free radicals to repair the scalp barrier; arctiin from burdock seeds reduces DHT production by inhibiting 5α-reductase activity, regulating sebum secretion from the root and preventing excess oil from providing a breeding ground for pathogens; salicin from white willow bark, after being converted into salicylic acid, can regulate the proliferation and differentiation cycle of keratinocytes, gently exfoliating dead skin cells. Eugenol, purified from clove extract, can directly destroy the cell membrane structure of pathogens such as Malassezia, causing their core substances to leak out and become inactive; the antibacterial agent, through compounding with solvents, forms an auxiliary antibacterial system, precisely supplementing the antibacterial effect.

[0039] 2. The components of this application's composition form a layered synergistic mechanism, addressing the shortcomings of traditional products. The functional components first establish a basic defense line of "anti-inflammatory, oil control, and keratin regulation," optimizing the scalp's microecology and paving the way for subsequent antibacterial ingredients. Clove extract, leveraging the improved scalp environment, penetrates more easily to exert a direct bactericidal effect, creating a dual effect of "environmental optimization + precise antibacterial action." The antibacterial agent further enhances the antibacterial effect while mitigating the dryness that salicylic acid may cause, achieving a balance between efficacy and gentleness. The scientific formulation ensures the full release of the basic efficacy of the functional components, with eugenol achieving a pathogenic bacteria inhibition rate of ≥90%, and the low proportion of the antibacterial agent avoiding scalp burden. Ultimately, it achieves a synergistic effect of "rapid dandruff removal, immediate itch relief, and long-term stabilization," overcoming the shortcomings of traditional products such as slow effectiveness, easy relapse, and strong irritation.

[0091] Performance testing

[0092] 1. Security Testing

[0093] Referring to the human skin patch test in the 2022 edition of the "Cosmetic Safety Technical Specifications," the above-mentioned plant-based anti-dandruff compositions of Examples 1-3 were tested to determine whether they would cause skin irritation or sensitization. The specific experimental steps are as follows:

[0094] (1) Ninety people aged 18-60 years were selected, corresponding to the compositions of Examples 1-3. Each group consisted of 15 males and 15 females, and none of them had serious skin diseases, allergies or immune diseases.

[0095] (2) Prepare a 5wt% aqueous solution sample from the compositions of Examples 1-3;

[0096] (3) Select an area not exceeding 50mm 2A qualified patch test apparatus with a depth of approximately 1 mm was used. 0.02 mL of the aqueous solution sample from Examples 1-3 was placed inside the patch test apparatus chamber. The control well was a blank control (without any substance). The patch test apparatus containing the finished product was applied to the healthy skin on both sides of the spine on the subject's back using hypoallergenic adhesive tape. The pad was gently pressed with the palm of the hand to ensure even application to the skin, and left for 24 hours. Skin reactions were observed 30 minutes (after the indentation disappeared), 24 hours, and 48 hours after the finished product was removed, and the results were recorded.

[0097] (4) The final results were all grade 0 with no reaction, indicating that the plant-based desquamation composition of the present invention has low irritation and high safety.

[0098] 2. Dandruff removal ability test

[0099] Dandruff is largely caused by the overgrowth of Malassezia furfur. When Malassezia furfur proliferates, it breaks down sebum to produce fatty acids. These fatty acids irritate the scalp, causing skin cells to shed more quickly and forming dandruff. Simultaneously, Malassezia furfur can also trigger scalp inflammation, exacerbating the dandruff problem. Therefore, the inhibition rate of Malassezia furfur can reflect the effectiveness of dandruff control.

[0100] Test method: *Malassezia furfur* was used as the test strain; *Malassezia furfur* culture medium was used. According to QB / T2738-2012 "Evaluation Method for Antibacterial and Bacteriostatic Effects of Daily Chemical Products", the compositions of Examples 1-6 and Comparative Examples 1-4 were prepared into samples with a mass concentration of 5% for evaluation of antibacterial effects. The viable count was 3.0 × 10⁻⁶. 4 CFU / mL, reaction time of the test substance was 10 min. The antibacterial results are shown in Table 1 below.

[0101] Table 1. Results of dandruff removal ability test

[0102]

[0103] As shown in Table 1, the compositions of Examples 1-6 of the present invention all exhibited inhibition rates of over 90% against Malassezia furfur, indicating excellent dandruff-removing ability. In contrast, the compositions of Comparative Examples 1-3 showed lower inhibition rates against Malassezia furfur than the compositions of the present invention, with the highest inhibition rate (85.2%) achieved by Comparative Example 3. This demonstrates that the components of the compositions of the present invention exhibit significant synergistic effects and are irreplaceable.

[0104] 3. Application Testing

[0105] Test samples: The compositions of Examples 1-6 and Comparative Examples 1-3 were prepared into shampoos according to the formulations in Table 2.

The test subjects were all dandruff patients aged 23 to 55 years, including 39 men and 33 women.

[0107] Testing period: March to April 2025, a total of 28 days, and the improvement after the 28th day was recorded.

[0108] Test method: This test includes dandruff, scalp dryness, scalp cleanliness, scalp oiliness, scalp itching, and scalp redness and swelling. The test is scored from 0 to 10. The higher the score, the better the improvement in the item. The specific results are shown in Table 3.
