Description

Technical Field

[0001] The present invention belongs to the technical field of hair care, and in particular relates to an anti-dandruff composition, a preparation method thereof, and application thereof in shampoo products. Background Art

[0002] In recent years, with the improvement of living standards and the growing emphasis on personal care, the functional requirements of shampoos have gradually diversified, with anti-dandruff efficacy becoming a key concern for consumers. Dandruff is primarily caused by the overgrowth of Malassezia fungi, whose metabolites can irritate the scalp, leading to abnormal shedding of the stratum corneum, accompanied by problems such as excessive oil secretion and itching. Therefore, the development of effective and safe anti-dandruff compositions is of great significance for improving scalp health.

[0003] Currently, commonly used anti-dandruff active ingredients in shampoos include zinc pyrithione (ZPT), ketoconazole, climbazole, salicylic acid, and the like. However, these ingredients have certain limitations in practical applications, such as high irritation and difficulty in achieving both oil-control properties. Furthermore, traditional anti-dandruff compositions often utilize a single active ingredient, making it difficult to simultaneously address multiple requirements, such as antibacterial and oil-control properties, resulting in unsatisfactory or recurring anti-dandruff effects. Therefore, there is an urgent need to develop a novel anti-dandruff composition to overcome the shortcomings of the prior art, address the inadequate antibacterial, oil-control, and anti-dandruff effects found in the prior art, and expand its application in shampoos. Summary of the Invention

[0004] The purpose of the present invention is to provide an anti-dandruff composition and its preparation method and application in shampoo products, which solves the problem that the existing anti-dandruff compositions added to shampoo products have poor antibacterial, oil-control and anti-dandruff effects.

[0005] The purpose of the present invention can be achieved through the following technical solutions:

[0006] The first aspect of the present application provides an anti-dandruff composition comprising the following raw materials:

[0007] Plant antibacterial components, oil-control components, moisturizing components, emulsifiers, solvents.

[0008] As a preferred technical solution of the present invention, the plant antibacterial component includes at least one of hops flower extract, radix scutellariae extract, inula flavescentis and chrysanthemum flower extract, tea extract, galangal extract and scutellariae baicalensis extract.

[0009] Preferably, the plant antibacterial component includes hops flower extract, radix scutellariae extract and inula fructus chrysanthemi extract;

[0010] Hops (HUMULUS LUPULUS) is a perennial herbaceous plant of the genus Humulus in the family Cannabaceae. The main active ingredients of hop flower extract are α-acids and total flavonoids, which can change the permeability of cell membranes, allowing intracellular substances to extravasate, thereby inhibiting bacterial growth.

[0011] PHRYMA LEPTOSTACHYA is a perennial herbaceous plant of the genus PHRYMA in the family PHRYMATIACEAE. The active ingredient in PHRYMA LEPTOSTACHYA extract is lignans, which can destroy the activity or synthesis of DNA, making it difficult for bacteria to reproduce.

[0012] Heterotheca inuloides is an herbaceous plant of the Asteraceae family. The main chemical components of Heterotheca inuloides extract are sesquiterpenes, flavonoids, etc., which can interfere with ATP synthesis, block energy metabolism and thus cause the death of microorganisms.

[0013] Furthermore, the plant antibacterial component includes 10-16 parts by weight of hops flower extract, 9-14 parts by weight of radix scutellariae extract, and 5-8 parts by weight of inula fructus and chrysanthemum flower extract.

[0015] Preferably, the oil-control component includes sodium C10-15 alkyl polyether sulfate, capryloyl glycine, potassium azelayl diglycinate and potassium cocoyl hydrolyzed oat protein;

[0016] The hydrophilic groups in sodium C10-15 alkyl ether sulfate can form tiny micelle structures with water to wrap the scalp oil, making it easier to rinse the excess oil on the scalp surface and remove dirt, oil and impurities on the hair.

[0017] Capryloylglycine inhibits the activity of 5-α reductase, thereby reducing the secretion of oil by the sebaceous glands;

[0018] Potassium azelayl diglycinate can maintain the balance of sebaceous gland secretion, inhibit excessive oiliness, and maintain the integrity of sebum structure;

[0019] Potassium cocoyl hydrolyzed oat protein has a good effect of soothing the scalp, alleviating dandruff and itching, and can maintain scalp health to a certain extent.

[0020] Furthermore, the oil-control component includes 2-3 parts by weight of sodium C10-15 polyether sulfate, 5-8 parts by weight of capryloyl glycine, 3-6 parts by weight of potassium azelayl diglycinate, and 4-6 parts by weight of potassium cocoyl hydrolyzed oat protein.

[0021] As a preferred technical solution of the present invention, the moisturizing component includes but is not limited to at least one of meadowfoam seed oil, coconut oil and camellia seed oil.

[0022] Preferably, the moisturizing component includes meadowfoam seed oil.

[0023] Furthermore, the moisturizing component includes 10-20 parts by weight of meadowfoam seed oil.

[0024] As a preferred technical solution of the present invention, the emulsifier includes cetearyl alcohol.

[0025] Furthermore, the emulsifier includes 5-8 parts by weight of cetearyl alcohol.

[0026] As a preferred technical solution of the present invention, the solvent includes deionized water.

[0027] As a preferred technical solution of the present invention, the solvent includes 40-60 parts by weight of deionized water.

[0028] The second aspect of the present application provides a method for preparing an anti-dandruff composition, comprising the following steps:

[0029] S1, controlling the temperature and stirring the plant antibacterial component, sodium C10-15 polyether sulfate, potassium azelayl diglycinate and solvent to obtain a mixture A, which is set aside;

[0030] S2. Stir the remaining oil-control component and moisturizing component at controlled temperature and speed to obtain mixed material B, which is set aside;

[0031] S3. After mixing the emulsifier and the mixed material A, the mixture is stirred at a controlled temperature and speed, and then the mixed material B is added and stirred again to obtain an anti-dandruff composition.

[0032] As a preferred technical solution of the present invention, the temperature of the temperature control in step S1 is 40-45°C.

[0033] As a preferred technical solution of the present invention, the temperature of the temperature-controlled and speed-controlled stirring in step S2 is 45-50°C, the stirring speed is 10-20 rpm / min, and the stirring time is 20-30 min.

[0034] As a preferred technical solution of the present invention, the temperature of the temperature-controlled and speed-controlled stirring in step S3 is 30-40°C, the stirring speed is 5-20rpm / min, and the stirring time is 20-30min; and the further stirring time is 0.5-1h.

[0035] The third aspect of the present application provides an anti-dandruff composition for use in preparing shampoo products, wherein the anti-dandruff composition is added at 3-5% of the total mass of the shampoo products.

[0036] Beneficial effects of the present invention:

[0037] (1) The present application preferably compounds three different types of extracts, namely, hop flower extract, radix schoenoprasum extract and chrysanthemum flower extract, effectively utilizing the different advantageous killing power of each extract on microorganisms, inhibiting the growth, reproduction and killing of the microbial flora that cause dandruff problems from different dimensions, and effectively making the prepared composition have outstanding antibacterial effect.

[0038] (2) Preferably, the present application combines sodium C10-15 alkyl polyether sulfate, capryloyl glycine, potassium azelayl diglycinate and potassium cocoyl hydrolyzed oat protein to respectively remove dirt and grease, reduce oil secretion, inhibit oily shine and soothe the scalp, so that the prepared composition has an excellent oil control effect.

[0039] (3) The generation of dandruff is closely related to the imbalance of the scalp microbial flora and the vigorous secretion of scalp oil. Therefore, the raw materials selected in this application combine antibacterial and oil-control functions, which can effectively regulate the balance of the scalp microbial flora and accurately control the oil secretion of the scalp. Through this design, the finished composition can show an excellent anti-dandruff effect and significantly improve the health of the scalp. DETAILED DESCRIPTION

[0097] Test Example 2: Oil control and anti-dandruff effect test

[0098] Test product: The anti-dandruff compositions prepared in Examples 1-3 and Comparative Examples 4-7 were added to shampoo with the same base at a concentration of 4% of the total mass of the shampoo to prepare the test product;

[0099] Test Method: Volunteers aged 25-50 years, both men and women, were randomly divided into 7 groups of 12 each. Each group was asked to clean their scalps with the test products prepared in Examples 1-3 and Comparative Examples 4-7. During the test period, hair bleaching and dyeing were prohibited, and no other hair care products were used. Scalp oil content was measured using a SEBUMETER to evaluate scalp oil secretion. Test conditions: 22°C, before use and 8 hours after shampooing with each test product, 10 different areas of the scalp were measured using a SEBUMETER. The average value was taken, and the reduction rate of scalp oil content after using each test product was calculated according to the following formula:

[0100] Scalp oil content reduction rate (%) = [(scalp oil content before shampooing - scalp oil content after shampooing) / scalp oil content before shampooing] × 100%;

[0101] At the same time, the anti-dandruff effect of volunteers using the test products prepared in Examples 1-3 was evaluated according to the following evaluation criteria:

[0102] Relief: Dandruff is significantly reduced and the scalp no longer itchy.

[0103] Significant improvement: Dandruff is reduced, and the intervals between scalp itching are longer and less severe.

[0104] Ineffective: There was no improvement in dandruff and scalp itching.

[0105] The results are shown in Table 2.

[0106] Table 2

[0107]

[0108]

[0109] As can be seen from Table 2, the composition prepared in this application has an excellent oil-control effect. This is because the composition combines sodium C10-15 alkyl ether sulfate, capryloyl glycine, potassium azelayl diglycinate, and potassium cocoyl hydrolyzed oat protein to effectively enhance the composition's oil-control effect on scalp oil by removing dirt and oil, reducing oil secretion, inhibiting shine, and soothing the scalp.

[0110] In addition, it is not difficult to find from Table 2 that the composition prepared in the present application also has a significant anti-dandruff effect.
