Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of cosmetics, and specifically relates to an oil-control and volumizing shampoo composition and a preparation method thereof. BACKGROUND

[0002] Oily scalp and flat hair are common hair care problems faced by many people. These problems are usually caused by a variety of factors such as disruption of scalp ecological balance, imbalance of oil secretion, and dysfunction of scalp cells. Excessive oil secretion not only affects the appearance of hair, but also can cause scalp itching, scaling, and other problems. Therefore, it is particularly important to develop a shampoo composition that can effectively control oil and give hair a volumizing effect.

[0003] Currently, there are various types of oil-control shampoo products on the market, but their effects vary. Some products may remove scalp oil by adding strong detergents, but long-term use can damage the natural barrier of the scalp, leading to dry and sensitive scalp. Some other products may use natural ingredients such as plant extracts to regulate scalp oil secretion, but the oil-control and volumizing effects are often not ideal.

[0004] In view of this, the present application aims to provide a new oil-control and volumizing shampoo composition and a preparation method thereof to overcome the shortcomings of existing products. SUMMARY

[0005] The purpose of the present application is to provide an oil-control and volumizing shampoo composition and a preparation method thereof, which, by scientifically proportioning various active ingredients, aims to fundamentally improve the scalp microecological environment, reduce scalp irritation, improve scalp health, regulate scalp water-oil balance, and promote scalp metabolism, thereby achieving the effects of oil control and volume.

[0006] An oil-control and volumizing shampoo composition, prepared from the following ingredients by mass percentage: active ingredients 0.1-11%, zinc salt 0.15-1.0%, capryloyl glycine 0.1-1.0%, bis(hydrogenated tallow) phthalic acid amide 0.1-0.6%, polyquaternary ammonium salt 0.1-1.6%, humectant 0.21-3.2%, lipid-adding agent 0.1-2.0%, B group vitamins 0.1-1.0%, surfactant 10-30%, and water carrier making up the rest to 100%; the water carrier includes sodium hydroxide.

[0007] Preferably, the active ingredients include white willow bark extract, camellia seed extract, aloe vera barbadensis miller extract, and bamboo leaf extract.

[0008] Preferably, the mass ratio of the Salix alba L. bark extract, Camellia oleifera Abel extract, Aloe vera L. extract, and Bamboo leaves extract is (0.05-2.0):(0.1-5.0):(0.05-2.0):(0.05-2.0).

[0009] The inventors have found that the use of Salix alba L. bark extract, Camellia oleifera Abel extract, Aloe vera L. extract, and Bamboo leaves extract as active ingredients can improve the oil control and volumizing effect of the shampoo composition and improve the health of the scalp. This may be because the four plant extracts have a synergistic effect, and the phenolic compounds and flavonoids in the Salix alba L. bark extract and Bamboo leaves extract have anti-inflammatory and antibacterial effects, reducing inflammation and bacterial growth on the scalp to create a healthy microenvironment for the scalp. The Camellia oleifera Abel extract is rich in antioxidant ingredients such as tea polyphenols and vitamin E, which can nourish the scalp and protect scalp cells from free radical damage, and the polysaccharides, amino acids, and other ingredients in the Aloe vera L. extract can together relieve scalp discomfort, provide necessary nutrients, and enhance the barrier function of the scalp. The combination of these four plant extracts not only more effectively reduces the secretion of sebum on the scalp, making the hair more voluminous and fluffy, but also reduces inflammation and bacterial infection on the scalp, improves the health of the scalp, and enhances the barrier function of the scalp, reducing damage to the scalp from external stimuli. In order to fully utilize the beneficial effects of these plant extracts, it is necessary to ensure that as many active ingredients as possible are present in the plant extracts.

[0010] The preparation methods of the four plant extracts are consistent. Taking the Salix alba L. bark extract as an example, the preparation method comprises the following steps: washing and drying the Salix alba L. bark, crushing it to pass through a 200-400 mesh sieve, adjusting the water content to 45%-55% to obtain a fermentation substrate, adding a fermentation agent, and culturing at 40-45°C until the pH is 4-4.5, then removing, dehydrating, and drying to obtain a fermentation product; mixing the fermentation product with 90%-95% ethanol solution and uniformly mixing, then performing supercritical extraction, and recovering the ethanol to obtain the active ingredient.

[0011] Preferably, the fermentation agent comprises Lactobacillus bulgaricus, Streptococcus thermophilus, Bacillus subtilis, and Lactobacillus casei.

[0012] The Lactobacillus bulgaricus has strain number CICC 25031; the Streptococcus thermophilus has strain number CICC 6038; the Bacillus subtilis has strain number ATCC 6633; and the Lactobacillus casei has strain number CICC 20241.

[0013] Preferably, the amount of Lactobacillus bulgaricus is 10 6 -10 7CFU / g of fermentation substrate; the amount of the Lactobacillus plantarum is 10 7 -10 8 CFU / g of fermentation substrate; the amount of the Bacillus subtilis is 10 7 -10 8 CFU / g of fermentation substrate; the amount of the Lactobacillus casei is 10 5 -10 6 CFU / g of fermentation substrate.

[0014] Preferably, the mass ratio of the fermentation product and 90%-95% ethanol solution is 1:(30-40).

[0015] Preferably, the supercritical extraction is performed under the following conditions: the amount of carbon dioxide is 2-4 times the amount of 90%-95% ethanol solution, the pressure is 30-40 MPa, the temperature is 35-45℃, and the time is 1-2 h.

[0016] The inventors have found that, in the preparation of the active ingredient, the fermentation technology combined with the supercritical extraction technology can further improve the oil control and volume effect of the shampoo composition, while ensuring the safety and stability of the shampoo composition. This may be because, first, the four kinds of fermentation agents are used to ferment the plants, and the Lactobacillus bulgaricus and Streptococcus thermophilus can synergistically produce lactic acid, reduce the pH value of the system, and promote the generation of beneficial metabolites; the Bacillus subtilis can decompose complex organic matter and release nutrients; and the Lactobacillus casei can help improve the flavor and texture of the fermentation product. The synergistic effect of the four kinds of fermentation agents not only accelerates the fermentation process, but also enriches the diversity and biological activity of the fermentation product, bringing more comprehensive health benefits to the final product. After fermentation, supercritical extraction is performed. Due to its high efficiency and environmental protection, supercritical extraction can effectively separate and enrich the target components, while avoiding the residual problems that may be caused by traditional solvent extraction. The combination of fermentation and supercritical extraction not only takes advantage of the fermentation process in biological transformation and flavor formation, but also utilizes the high efficiency and purity of supercritical extraction. Under the synergistic effect of the two, the obtained active ingredient not only has higher purity, but also has stronger biological activity, effectively retaining various active substances and nutritional ingredients in the raw materials, and improving the overall quality and functional value of the product. This preparation method not only optimizes the extraction efficiency of the active ingredient, but also ensures the safety and stability of the final product, providing strong support for the development of efficient and natural health products.

[0017] The zinc salt includes zinc chloride 0.05%-0.1%, zinc pyrrolidone carboxylate 0.05%-0.7%, and zinc gluconate 0.05%-0.2%, by mass percentage of the oil control and volume shampoo composition.

[0018] The inventors found that the combination of specific zinc salt and capryloyl glycine, together with natural active ingredients, can greatly improve the oil control effect of the shampoo composition. This may be due to the significant synergistic effect between these components. Zinc chloride, zinc pyrrolidone carboxylate and zinc gluconate as zinc salts, zinc ions can penetrate into the skin, balance the secretion of sebum, reduce the production of sebum, and also have certain anti-inflammatory effect, which helps to alleviate the skin problems caused by excessive sebum. Capryloyl glycine as a mild and effective skin conditioner has good antibacterial and antilipid properties, which can further inhibit the growth of bacteria on the skin surface and reduce the excessive secretion of sebum caused by bacterial activity. When these two are used together with natural active ingredients, the zinc salt controls the secretion of sebum from the source, the capryloyl glycine inhibits the activity of bacteria and reduces the cause of excessive secretion of sebum, and the natural active ingredients regulate the skin condition and enhance the skin health, providing long-lasting support for oil control effect. This combination not only improves the oil control efficiency, but also ensures the mildness and safety of the product, meeting the needs of modern consumers for efficient, safe and healthy skin care.

[0019] The humectant includes sorbitol 0.1%-2.0%, trimethyl glycine 0.1%-1.0%, and arginine 0.01%-0.2% by mass percentage of the oil control and fluffy shampoo composition.

[0020] The emollient includes C12-13 alcohol lactic acid ester 0.05%-1.0% and linoleamide propyl PG-dimethyl ammonium phosphate 0.05%-1.0% by mass percentage of the oil control and fluffy shampoo composition.

[0021] Preferably, the acid value of the C12-13 alcohol lactic acid ester is 0.5-0.7 mgKOH / g, and the ester content is 70%-90%; further preferably, the acid value of the C12-13 alcohol lactic acid ester is 0.6 mgKOH / g, and the ester content is 75%-85%.

[0022] In some preferred embodiments, the C12-13 alcohol lactic acid ester is purchased from Jining Tangyi Chemical Co., Ltd.

[0023] Preferably, the pH value of the linoleamide propyl PG-dimethyl ammonium phosphate is 6.5-7.5, the HLB value is 17-19, and the solid content is ≥30%.

[0024] In some preferred embodiments, the linoleamide propyl PG-dimethyl ammonium phosphate is purchased from Shanghai Zhiyuan Biological Technology Co., Ltd.

[0025] The inventors found that the combination of specific moisturizing agents and specific emollients can effectively moisturize the scalp and significantly reduce the problem of excessive sebum secretion caused by dry skin. This may be because sorbitol, trimethylglycine and arginine as moisturizing agents not only form a thin and durable moisturizing film on the scalp surface, effectively lock in moisture and prevent the scalp from drying out, but also provide the necessary moisture to the scalp, and maintain the water-oil balance by adjusting the scalp microenvironment, thereby avoiding the abnormal activity of sebaceous glands caused by water deficiency and reducing the excessive secretion of sebum. And C12-13 alcohol lactate and linoleamidopropyl PG-dimethyl ammonium phosphate as emollients further enhance the moisturizing and protective properties of the scalp by supplementing and strengthening the natural lipid layer of the scalp. They can form a smooth lipid barrier to reduce the evaporation of scalp moisture, while increasing the softness and smoothness of the scalp, keeping the scalp healthy and moisturized. This moisturizing effect not only relieves the dryness of the scalp, but also indirectly reduces the excessive secretion of sebum caused by dry irritation. In addition to the direct moisturizing and oil control effect, the combination of moisturizing agents and emollients can also enhance the barrier function of the scalp, improve the resistance of the scalp to external stimuli, reduce the production of dandruff, and promote scalp health. At the same time, these ingredients have good skin compatibility and safety, and can gently care for the scalp, reducing sensitive or inflammatory reactions caused by chemical ingredients.

[0026] The B vitamins include vitamin B5 0.01%-0.8%, vitamin B3 0.01%-0.5%, by mass percentage of the oil control fluffy shampoo composition.

[0027] The polyquaternium includes polyquaternium-10 0.01%-0.6%, polyquaternium-7 0.05%-1.0%, by mass percentage of the oil control fluffy shampoo composition.

[0028] Preferably, the polyquaternium-10 has a volatile matter ≤6%, ash ≤3%, and a viscosity of 300-500 cps when the mass concentration of the polyquaternium-10 in an aqueous solution at room temperature is 2%.

[0029] In some preferred embodiments, the polyquaternium-10 is purchased from Shanghai Maikelin Biochemical Technology Co., Ltd.

[0030] Preferably, the polyquaternium-7 has a viscosity of 8000-15000 cps at room temperature, and a pH value of 5-8 when the mass concentration of the polyquaternium-7 in an aqueous solution is 1%.

[0031] In some preferred embodiments, the polyquaternium-7 is purchased from Yunfu Haixing Environmental Protection Technology Co., Ltd.

[0032] The inventors discovered that by using bis(hydrogenated tallow-based) phthalamide and specific polyquaternium salts, an elastic film can be formed on the hair surface, improving hair elasticity and volume. Bis(hydrogenated tallow-based) phthalamide is a cationic surfactant with good skin affinity and wetting properties. It can form a thin film on the hair surface, which not only reduces friction between hair strands but also locks in moisture, making the hair softer and smoother. The combination of polyquaternium-10 and polyquaternium-7 has excellent conditioning and smoothing effects. They can adsorb onto the negatively charged hair surface, forming a uniform protective film. This film not only enhances the elasticity and resilience of the hair but also prevents damage from the external environment. When bis(hydrogenated tallow) phthalamide is used in combination with polyquaternium-10 and polyquaternium-7, they exhibit a synergistic effect. The film formed by bis(hydrogenated tallow) phthalamide provides a stable substrate for the polyquaternium salts, allowing them to adhere better to the hair surface. The polyquaternium salts, through their cationic properties, further enhance the stability and uniformity of the film, making it more robust and durable. This composite film not only improves hair elasticity and resilience but also enhances hair volume, making it appear fuller and more vibrant. Furthermore, this combination reduces scalp oil secretion, improves the scalp microenvironment, reduces dandruff, and increases hair smoothness and shine, making it easier to manage and style. It also exhibits good skin compatibility and safety, gently caring for the scalp and hair and reducing sensitivity or inflammatory reactions caused by chemical irritants.

[0033] The surfactants comprise, by weight percentage, sodium lauryl ether sulfate 5.0%-20.0%, cocamidopropyl betaine 0.5%-5.0%, disodium cocoamphodiacetate 0.5%-3.0%, and cocamide MEA 0.5%-3.0%.

[0034] Preferably, the sodium lauryl ether sulfate contains ≥70% active ingredient, ≤2.5% unsulfated product, and ≤1.5% sodium sulfate.

[0035] Preferably, the cocamidopropyl betaine has an active ingredient content of 29%-31%, a free amine content of ≤0.1%, and a solid content of ≥35%.

[0036] In some preferred embodiments, both sodium lauryl ether sulfate and cocamidopropyl betaine are purchased from Guangzhou Gongxin Chemical Co., Ltd.

[0037] Preferably, the active ingredient content in the disodium cocoamphodiacetate is 28%-32%, and the pH value in the aqueous solution is 4-8 when the mass concentration of disodium cocoamphodiacetate is 10%.

[0038] Preferably, the cocoamide MEA contains 85%-88% active ingredient and ≤6% free amine.

[0039] In some preferred embodiments, both the disodium cocoamphodiacetate and cocamide MEA are purchased from Guangdong Riyou Technology Co., Ltd.

[0040] Based on the mass percentage of the oil-controlling and volumizing shampoo composition, the aqueous carrier comprises 0.1%-0.5% sodium benzoate, 0.1%-1.0% phenoxyethanol, 0.05%-0.2% disodium EDTA, 0.1%-2.0% sodium chloride, 0.05%-1.2% fragrance, 0.01%-0.4% sodium hydroxide, with the balance being water.

[0041] The fragrances mentioned are not specifically limited, and include, but are not limited to, rose fragrance, magnolia fragrance, sweet orange fragrance, vanilla fragrance, and peppermint fragrance.

[0042] Preferably, the mass ratio of capryloylglycine to sodium hydroxide is 3:(1.0-1.2).

[0043] The preparation method of the oil-controlling and volumizing shampoo composition includes the following steps:

[0044] S1. Take 3-7% of the total mass of water, add octanoyl glycine and sodium hydroxide, stir and neutralize until completely dissolved and homogeneous to obtain a pre-prepared solution;

[0045] S2. Stir the remaining water and polyquaternium-10 until completely dissolved and transparent;

[0046] S3. Add surfactant to the product obtained in step S2, heat to 75-85℃, and stir until completely dissolved.

[0047] S4. Add di(hydrogenated tallow) phthalamide, zinc salt, humectant, and fat-enhancing agent to the product obtained in step S3, keep warm at 75-85℃ and stir for 25-35 minutes, then cool down to below 45℃.

[0048] S5. Add the pre-mixed solution, active ingredient, polyquaternium-7, B vitamins and the remaining components to the product obtained in step S4, stir well, and let stand to obtain the oil-controlling and volumizing shampoo composition.

[0049] In some preferred formulations, the mass ratio of capryloyl glycine to sodium hydroxide needs to be precisely controlled. Furthermore, during the preparation of the shampoo composition, a portion of water is first mixed thoroughly with both. This is likely because capryloyl glycine, as a weakly acidic amino acid derivative, can precisely control the pH value of the shampoo composition by adjusting its mass ratio with the strongly alkaline sodium hydroxide. This directly affects the shampoo's cleansing effect, oil control and volumizing effect, scalp gentleness, and hair health care. A suitable pH value not only optimizes the performance of the shampoo composition but also ensures its safety, preventing damage to the scalp and hair from excessive alkalinity. Simultaneously, mixing a portion of water with capryloyl glycine and sodium hydroxide beforehand improves the solubility and dispersibility of these components in water, preventing incomplete dissolution or excessively high local concentrations that could result from direct addition to the entire formulation. In addition, this step effectively controls the reaction rate of sodium hydroxide and capryloyl glycine in the aqueous solution, avoiding adverse reactions and thus ensuring the high quality, stability, and safety of the shampoo composition.

[0109] The difference between this comparative example and Example 1 is that, based on the mass percentage of the oil-controlling and volumizing shampoo composition, the aqueous carrier is 0.2% sodium benzoate, 0.5% phenoxyethanol, 0.1% disodium EDTA, 1.0% sodium chloride, 0.5% fragrance, 0.4% sodium hydroxide, and the remainder is water.

[0110] Comparative Example 10

[0111] The difference between this comparative example and Example 1 is that the preparation method of the oil-controlling and volumizing shampoo composition includes the following steps:

[0112] S1. Stir water and polyquaternium-10 at 400 r / min for 20 min;

[0113] S2. Add surfactant to the product obtained in step S1, heat to 80°C, and stir at 600 r / min for 30 min.

[0114] S3. Add di(hydrogenated tallow) phthalamide, zinc salt, humectant, and fat-reducing agent to the product obtained in step S2, keep warm at 80°C and stir at 400 r / min for 30 min, then cool down to below 45°C.

[0115] S4. Add the pre-prepared solution, active ingredient, polyquaternium-7, B vitamins and the remaining components to the product obtained in step S3, stir at 400 r / min for 30 min, let stand, and the oil-controlling and volumizing shampoo composition is obtained.

[0116] Performance testing

[0117] The oil-control effect of the shampoo was determined by testing its inhibition rate of 5α-reductase activity, as described in patent CN 117482002A. A higher inhibition rate of 5α-reductase activity indicated a stronger oil-control effect. The volume effect was determined by testing the change in hair volume before and after shampooing, as described in patent CN 116807953A. A higher volume change rate indicated a better volume effect. Consumer evaluation was conducted using the method described in patent CN 116807953A. Volume and oil-control scores ranged from 1 to 10, with higher scores indicating better effects; higher volume indicated better oil control. Ten consumers participated in each sample test for two weeks. Shampooing frequency varied depending on individual circumstances, but at least once every three days. The highest and lowest scores were removed, and the average score was taken. The results are shown in Table 1.

[0121] According to statistics, the oil-controlling and volumizing shampoo compositions prepared in Examples 1-3 of this invention have good oil-controlling and volumizing effects. Comparative Example 1 did not add any active ingredients; Comparative Example 2 did not add white willow bark extract; Comparative Example 3 did not use fermentation technology combined with supercritical extraction technology to prepare active ingredients; Comparative Example 4 did not add Lactobacillus bulgaricus; Comparative Example 5 did not add zinc salt; Comparative Example 6 only used sorbitol as a moisturizer; Comparative Example 7 did not add linoleamide propyl PG-dimethylammonium chloride phosphate; Comparative Example 8 did not add di(hydrogenated tallow) phthalamide; Comparative Example 9 added excessive sodium hydroxide; and Comparative Example 10 did not first mix a portion of water with capryloyl glycine and sodium hydroxide evenly during the preparation of the shampoo composition. The resulting shampoo compositions had poor oil-controlling and volumizing properties. This indicates that the shampoo compositions prepared using the raw materials and methods described in this application, through the scientific formulation of multiple active ingredients, aim to fundamentally improve the scalp's microecological environment, improve scalp health, regulate the scalp's water-oil balance, and promote scalp metabolism, thereby achieving the effect of oil control and volumizing.

[0122] The above description represents the preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
