Description

A hair care composition and its application Technical Field

[0001] This invention relates to the field of daily chemical products, and more particularly to a hair care composition and its application. Background Technology

[0002] Current hair care compositions primarily use silicone oil, which forms a hydrophobic film on the hair surface, providing immediate smoothness and tangle-reducing effects. However, most existing shampoos, conditioners, and hair masks struggle to achieve both good moisturizing effects and excellent combing ability when wet. Therefore, how to coat the hair with a hydrophobic protective film to achieve both good moisturizing effects and good combing ability when wet has been a research focus. Summary of the Invention

[0003] In view of the shortcomings of the prior art, the technical problem solved by the present invention is to provide a hair care composition and hair mask that can effectively enhance the deep moisturizing ability of hair and improve the combing performance of wet hair.

[0004] To solve the above technical problems, the present invention adopts a hair care composition, which is composed of the following components by mass percentage: glutamic acid 3%-6%, rapeseed oil amide propyl dimethylamine 9%-12%, panthenol 4%-8%, hydrolyzed wheat protein 4%-8%, preservative 0.2%-0.4%, and the balance is pure water. The sum of the mass percentages of the above components is 100%. The preparation method of the hair care composition includes the following steps: (1) weigh each raw material according to the proportion; (2) add glutamic acid to pure water, heat to 80°C, stir to dissolve, add rapeseed oil amide propyl dimethylamine and homogenize; (3) cool to below 45°C and add panthenol, hydrolyzed wheat protein and preservative in sequence; (4) filter and remove from the pot to obtain the finished product.

[0005] Furthermore, the preservative is at least one of phenoxyethanol or ethylhexylglycerin.

[0006] To solve the above-mentioned technical problems, another technical solution adopted by the present invention is a hair mask containing the above-mentioned hair care composition, which is composed of the following components by mass percentage: hair care composition: 15%-25%; cetearyl alcohol: 6%-7.5%; glycerin: 2%-5%; behenyltrimethylammonium chloride: 1.5%-2.5%; glyceryl stearate: 1%-3%; polyethylene glycol-14M: 0.2%-0.5%; bis-aminopropylpolydimethylsiloxane: 1%-2%; XIAMETER™ PMX-1501 Fluid: 0.5%-2.5%, wherein the XIAMETER™ PMX-1501 Fluid is a mixture of cyclopentamethoxysiloxane and polydimethylsiloxane alcohol; phenoxyethanol: 0.3%-0.8%; ethylhexylglycerin: 0.04%-0.08%; purified water: balance; the sum of the mass percentages of the above components is 100%.

[0007] Further, the preparation method of the above hair mask includes the following specific steps: (1) Glycerin, behenyltrimethylammonium chloride, glyceryl stearate, polyethylene glycol-14M and hair care composition are added in sequence to form phase A. Phase A is heated to 85°C and stirred until all components are completely dissolved; (2) Cetearyl alcohol is heated to 85°C separately as phase B to completely dissolve it; (3) Phase B is slowly poured into phase A, and then emulsified and homogenized for 3-5 minutes, followed by stirring and cooling; (4) When the temperature of the mixture drops to 55-60°C, bis-aminopropylpolydimethylsiloxane and XIAMETER™ PMX-1501 Fluid are added and stirred evenly; (5) When the temperature drops further to 45°C, phenoxyethanol and ethylhexylglycerin are added and stirred evenly to obtain the final product.

[0008] Furthermore, the above-mentioned hair care composition is used in hair conditioner, hair mask, or shampoo.

[0009] Compared to existing technologies, the hair care composition of this application, through the synergistic effect of glutamic acid, rapeseed oil amide propyl dimethylamine, panthenol, and hydrolyzed wheat protein, solves the problem that existing hair care products struggle to simultaneously achieve good moisturizing effects and good combing ability when hair is wet. This composition forms a protective film on the hair surface, which not only locks in moisture and provides a moisturizing effect, but also reduces friction in wet hair, thereby improving hair smoothness and combability, and enhancing the user's combing experience when hair is wet. Detailed Implementation

[0010] The specific implementation methods of the present invention will be further described below with reference to examples and experiments, but these are not intended to limit the present invention.

[0011] Unless otherwise specified, the raw materials, reagents or devices used in the various embodiments of the present invention can be obtained from conventional commercial sources or by existing known methods.

[0012] A hair care composition, as detailed in Examples 1 to 3, comprises the following components by weight percentage, as shown in Table 1 below: Table 1

[0013] Note: The preservative is at least one of phenoxyethanol or ethylhexylglycerin.

[0014] The preparation methods of Examples 1 to 3 above include the following steps: (1) weigh each raw material according to the proportion; (2) add glutamic acid to pure water, heat to 80°C, stir to dissolve, add rapeseed oil amide propyl dimethylamine and homogenize; (3) cool to below 45°C and add panthenol, hydrolyzed wheat protein and preservative in sequence; (4) filter and remove from the pot to obtain the finished product.

[0015] Glutamic acid is an amino acid that is often used in hair care compositions as a moisturizer and conditioner, helping to improve hair texture and shine.

[0016] Specifically, rapeseed oil amide propyl dimethylamine is a cationic surfactant that mainly functions as an antistatic, conditioning, and smoothing agent in hair care products. It can reduce hair tangles and improve the combability of wet and dry hair.

[0017] Panthenol, also known as vitamin B5, is a moisturizer and emollient that can penetrate the hair shaft to provide nourishment and enhance hair elasticity and shine.

[0018] Hydrolyzed wheat protein is a protein extracted from wheat through hydrolysis. It has film-forming and moisturizing properties, allowing it to adhere to the surface of hair strands and form a protective film, thereby enhancing hair strength and resilience.

[0019] Preservatives are used to inhibit the growth of microorganisms, ensuring the stability and safety of hair care compositions during storage and use.

[0020] Pure water serves as the solvent and primary carrier of the hair care composition, ensuring that the components can be dispersed and dissolved, and providing the necessary base volume for the product.

[0021] The hair care compositions of Examples 1 to 3, through the synergistic effect of glutamic acid, rapeseed oil amide propyl dimethylamine, panthenol, and hydrolyzed wheat protein, can solve the problem in existing hair care products that it is difficult to simultaneously achieve moisturizing effects and combing power on wet hair. This composition forms a protective film on the hair surface, which not only locks in moisture and provides a moisturizing effect, but also reduces friction in wet hair, thereby improving hair smoothness and combability, and enhancing the user's combing experience when hair is wet.

[0022] The preservative is at least one of phenoxyethanol or ethylhexylglycerin. Specifically, phenoxyethanol is a preservative widely used in cosmetics and personal care products. Its main function is to inhibit the growth of microorganisms such as bacteria, yeast, and mold, thereby preventing product spoilage. Phenoxyethanol has good chemical stability, is not easily decomposed, and maintains its preservative activity over a wide pH range. Furthermore, it has good compatibility with other common ingredients in hair care compositions, is unlikely to cause adverse reactions, and has low irritation to skin and hair at recommended concentrations, making it highly safe.

[0023] Ethylhexylglycerin is a multifunctional ingredient commonly used as a preservative synergist and emollient. As a preservative synergist, it enhances the antibacterial effects of other preservatives (such as phenoxyethanol), thus achieving the same preservative effect while reducing the concentration of the primary preservative. This helps reduce the total amount of preservatives in the formulation, further improving the product's gentleness. Simultaneously, ethylhexylglycerin itself also has emollient and moisturizing properties, providing additional conditioning effects to hair care compositions and helping to improve hair softness and shine.

[0024] In the above hair care composition, phenoxyethanol or ethylhexylglycerin can be used alone or in combination. When used together, phenoxyethanol provides broad-spectrum direct antibacterial activity, while ethylhexylglycerin acts as a synergist, enhancing the preservative effect of phenoxyethanol and providing additional moisturizing benefits. This combination achieves a more comprehensive and efficient preservative system while optimizing the product's gentleness and sensory experience.

[0025] By employing the aforementioned technical solution, selecting at least one of phenoxyethanol or ethylhexylglycerin as a preservative in the hair care composition effectively addresses the potential problems of poor preservative efficacy, poor compatibility, or high irritation associated with general-purpose preservatives. Specifically, phenoxyethanol, as a highly effective and broad-spectrum preservative, ensures that the hair care composition is protected from microbial contamination during storage and use, thereby extending the product's shelf life and ensuring consumer safety. Simultaneously, ethylhexylglycerin, as a preservative synergist, not only synergistically enhances the antibacterial activity of phenoxyethanol, achieving ideal preservative effects even at lower total preservative concentrations, thus reducing potential irritation, but also provides additional moisturizing benefits, further enhancing the hair care composition's conditioning effect on hair. This specific preservative selection allows the hair care composition to maintain excellent preservative performance while also considering the formula's gentleness, stability, and hair care effects, thereby improving the overall product quality and user satisfaction.

[0026] A hair mask containing the above-described hair care composition, as detailed in Examples 4 to 6, is composed of the following components by weight percentage, as shown in Table 2 below: Table 1

[0027] The hair care composition, as the core active ingredient of the hair mask, contains glutamic acid, rapeseed oil amide propyl dimethylamine, panthenol, hydrolyzed wheat protein, and preservatives. These ingredients work synergistically to provide the hair mask with basic conditioning and repair capabilities, such as nourishing, repairing, and protecting.

[0028] Cetearyl alcohol is a fatty alcohol that primarily functions as an emulsifier, thickener, and conditioner in hair masks. It imparts the appropriate consistency to the hair mask, helps other ingredients disperse evenly, and forms a protective film on the hair surface, providing smoothness and shine. Its role is to improve the texture and spreadability of the hair mask, while enhancing its conditioning effects.

[0029] Glycerin, a polyol, functions as a moisturizer in hair masks. It draws moisture from the air and retains it in the hair, effectively preventing dryness and increasing softness and elasticity. The addition of glycerin helps enhance the moisturizing effect of the hair mask, keeping hair hydrated.

[0030] Behenryltrimethylammonium chloride is a cationic surfactant primarily used as an antistatic agent and conditioner. It neutralizes the negative charge on hair, reducing static electricity and making hair easier to comb. Simultaneously, it forms a thin film on the hair surface, providing smoothness and shine, and improving the feel of the hair.

[0031] Glyceryl stearate is a nonionic emulsifier and emollient. It helps stabilize the emulsion system of hair masks, preventing oil-water separation, while also providing lubrication and softness to the hair surface, enhancing the conditioning effect of the hair mask.

[0032] Polyethylene glycol-14M is a water-soluble polymer primarily used as a thickener and film-forming agent. It increases the viscosity of hair masks, improves their rheological properties, and makes them easier to apply. Simultaneously, it forms a thin film on the hair surface, providing additional smoothness and protection.

[0033] Bis-aminopropyl polydimethylsiloxane is an amino silicone oil with excellent conditioning properties. It selectively adheres to damaged hair areas, repairs the hair cuticle, and provides superior smoothness, shine, and combability while reducing friction damage to the hair.

[0034] XIAMETER™ PMX-1501 Fluid is a blend of cyclopentamethoxysiloxane and polydimethylsiloxane alcohol. Cyclopentamethoxysiloxane acts as a volatile carrier, helping to evenly distribute other active ingredients and evaporating quickly after application without leaving a greasy residue. Polydimethylsiloxane alcohol provides long-lasting smoothness and shine, improving the feel and appearance of hair. This combination offers both immediate and long-lasting conditioning effects.

[0035] Phenoxyethanol and ethylhexylglycerin work together as a preservative system to ensure the microbial stability of the hair mask during storage and use, preventing product spoilage. Phenoxyethanol is a broad-spectrum preservative, while ethylhexylglycerin enhances its preservative effect and also has some moisturizing properties.

[0036] By scientifically combining the above-mentioned hair care composition with a variety of functional ingredients, this application provides a hair mask with superior deep nourishing and repairing effects. The addition of cetearyl alcohol and glycerin significantly improves the texture and moisturizing properties of the hair mask, allowing it to adhere better to the hair strands and provide long-lasting hydration. Behenryl trimethylammonium chloride and bis-aminopropylpolydimethylsiloxane work synergistically to effectively neutralize static electricity, repair damaged hair cuticles, and significantly improve hair smoothness, shine, and combability. XIAMETER™ PMX-1501 Fluid further enhances the conditioning effect of the hair mask, providing a silky feel without being greasy. This complex formula allows active ingredients to penetrate deeper into the hair strands, providing more comprehensive repair and protection, thus effectively overcoming the limitations of single hair care compositions in deep conditioning and hair quality improvement, bringing consumers a superior hair care experience.

[0037] The preparation method of hair masks in Examples 4 to 6 above includes the following specific steps: (1) Glycerin, behenyltrimethylammonium chloride, glyceryl stearate, polyethylene glycol-14M and hair care composition are added in sequence to form phase A. Phase A is heated to 85°C and stirred until all components are completely dissolved; (2) Cetearyl alcohol is heated to 85°C separately as phase B to completely dissolve it; (3) Phase B is slowly poured into phase A, and then emulsified and homogenized for 3-5 minutes, followed by stirring and cooling; (4) When the temperature of the mixture drops to 55-60°C, bis-aminopropylpolydimethylsiloxane and XIAMETER™ PMX-1501 Fluid are added and stirred evenly; (5) When the temperature drops further to 45°C, phenoxyethanol and ethylhexylglycerin are added and stirred evenly to obtain the final product.

[0038] Furthermore, the above-mentioned hair care composition is used in hair conditioner, hair mask, or shampoo.

[0039] Specifically, using the hair care composition in a conditioner means combining the composition as one of the active ingredients with other conditioning agents, emulsifiers, thickeners, etc., to prepare a product for nourishing, smoothing, and improving the combability of hair after shampooing. Through this application, the active ingredients in the hair care composition can act directly on the hair surface, providing the daily care required.

[0040] Using the hair care composition in a hair mask refers to using this composition as the core active ingredient, combined with other nourishing ingredients, repairing agents, film-forming agents, etc., to prepare a product for deep repair and intensive care of the hair. This application method usually requires a longer working time to allow the active ingredients in the hair care composition to penetrate more fully and exert their repairing and nourishing effects.

[0041] Using the hair care composition in shampoo means mixing the composition as a functional additive with surfactants, foaming agents, thickeners, etc., to prepare a product for cleaning the hair and scalp while providing basic hair care effects. In this application, the hair care composition can provide initial nourishment and protection to the hair during the cleansing process, improving the condition of the hair after shampooing.

[0042] The hair care composition of this application can be used as a base ingredient in products such as conditioners, hair masks, or shampoos. When a user uses a conditioner containing this hair care composition, its mechanism of action is as follows: Rapeseed oil amide propyl dimethylamine, as a cationic surfactant, can effectively adsorb onto the negatively charged hair surface, forming a uniform hydrophobic protective film. This protective film significantly reduces the friction between hair strands, thereby providing a good combing experience in wet hair and solving the problem of wet hair tangling.

[0043] Simultaneously, glutamate, panthenol, and hydrolyzed wheat protein work synergistically to provide deep nourishment and hydration to the hair. Glutamate helps regulate the pH balance of the hair, panthenol penetrates deep into the hair shaft to provide long-lasting hydration, while hydrolyzed wheat protein repairs damaged hair, enhances hair resilience, and further strengthens the moisturizing effect of the protective film. The addition of preservatives phenoxyethanol and ethylhexylglycerin ensures the product's microbial stability during storage and use.

[0044] Through this combination of components, hair receives both a hydrophobic protective film and ample internal nourishment and external hydration, effectively solving the problem of balancing moisturizing and combing power in existing technologies. Compared to existing silicone-based hair care products, this hair care composition forms a hydrophobic film through rapeseed oil amide propyl dimethylamine, avoiding the buildup that silicone oil may cause, while exhibiting excellent performance in both combing power and moisturizing effect in wet hair. Its innovation lies in achieving smooth, combable, and long-lasting moisturizing hair through the synergistic effect of specific components without relying on silicone oil.

[0045] To verify the moisturizing and combing effects of the hair mask containing the hair care composition of this application, the following comparative experiment was conducted: A hair mask containing the hair care composition of this application, as detailed in Examples 7 to 9, is composed of the following components by mass percentage, as shown in Table 3 below: Table 3

[0046] The comparative experiments are shown in Table 4 below: Table 4

[0047] Test 1: Moisturizing Efficacy Test 1. Test Basis: ALSSOP-042 "Operating Procedure for Weighing Hair Moisture Content" 2. Test Purpose and Principle: By weighing the hair strands of the test sample and the negative control group (before use, 1h, 2h, and 4h after use), the moisture content of the hair strands after use is compared to whether the moisturizing rate of the hair strands after use is higher than that of the negative control group, thereby verifying the moisturizing effect of the product.

[0048] Hair strands have the ability to absorb moisture, and their moisture content can be determined by weighing them. Changes in the moisture content of the hair strand reflect the effect of the test sample on its moisturizing ability. In the hair strand moisturizing test, glycerin was used as a positive control. After using the test sample, the moisture retention rate of the hair strand was higher than that of the positive control group, indicating that the test sample has a moisturizing effect on the hair strand.

[0049] 3. Experimental materials and instruments: Black, unprocessed flat hair bundle, 15cm, 2.5g; electronic balance.

[0050] 4. Test environment: Temperature: 21.0℃±1.0℃; Humidity: 50%±10%.

[0051] 5. Test plan ① Randomly select 10 identical flat hair bundles (2.5g, 15cm, healthy hair bundles), equilibrate in a constant temperature and humidity environment [(21±1)℃, (50±10)%RH] for 24 hours, and randomly divide them into 2 groups, a control group and a sample group, each with 5 bundles.

[0052] ②Weigh the two groups of hair bundles initially and record the mass m0.

[0053] ③ After washing the hair strands, wipe off excess water. For the sample group, apply 0.1g of sample to each hair strand, leave for 2 minutes, then rinse with running water for 30 seconds, repeating this process 3 times. For the control group, rinse each hair strand with running water for 30 seconds, repeating this process 3 times. Both the sample and control groups were then left to stand in a constant temperature and humidity environment.

[0054] ④ Weigh the hair bundle at 1h, 2h, and 4h respectively, and record the mass T. 1h T 2h T 4h .

[0055] 4. Descriptive Statistics of Test Results: The mean moisturizing rate of the moisturizing efficacy test results is shown in Table 5 (unit: %): Table 5:

[0056] Note: Hair bundle moisture retention rate refers to the rate of moisture retention when comparing the hair bundle mass after using the sample for a specified time with the hair bundle mass before using the sample. The calculation formula is as follows: Moisturizing rate T = (m1 - m0) / m0 Where, m------ hair bundle mass after using the sample for time t M------ hair bundle mass before using the sample In summary, through test 1, it can be seen that Examples 7-9 have good moisturizing effects in all time periods, Comparative Example 1 has relatively poor moisturizing effects in all time periods, while Examples 2 and 3 have relatively good moisturizing effects. By comparing Comparative Examples 1-3 with Examples 7-9 in all time periods, it can be seen that Example 7 has the best moisturizing effect.

[0057] Test 2: Hair Care Efficacy Test 1. Purpose and Principle of the Test The resistance encountered when combing hair comes from the friction between the hair and the comb, as well as between hair strands. Hair that is easy to comb or less prone to tangling experiences less resistance during combing. The resistance encountered during combing is usually measured by parameters such as the force (or load) or work done throughout the combing process. In this method, the comb moves at a constant speed from root to tip on the combing testing instrument, and the combing force or work is calculated based on the data. The effect of the cosmetic hair care product is characterized by the change in combability before and after the sample is used.

[0058] 2. Test Indicators - Combing Power Judgment Criteria: Compared with the baseline test, the combing power of the sample treatment test was significantly reduced, and the improvement rate of combing ability was greater than zero, indicating that the tested sample has the effect of improving hair combing ability and has hair care effect.

[0059] 3. Experimental Materials and Methods 3.1 Instruments and Materials: Combing tester: XJ810; Electronic balance: JJ1000; Slightly damaged hair strands: length ≥10cm, net weight ≥6g.

[0060] 3.2 Reagents: Cleaning solution: K12 (sodium dodecyl sulfate) 3.3 Test environment: Ambient temperature 23℃±2℃; relative humidity 60%±10%.

[0061] 3.4 Test Methods (1) Sample Treatment Test Wet Hair Combing Test: Apply 0.2 grams of sample per gram of hair strand evenly to the surface of the hair strand for about 30 seconds, let stand for about 1 minute, and then rinse. Fix the treated hair strand in the test position and start the combing cycle test.

[0062] Dry hair combing test: After the wet combing test, the hair strands are placed in a constant temperature and humidity chamber and left to dry for more than 4 hours. The hair strands are then removed and fixed in the test position, and the combing cycle test begins.

[0063] (2) Experimental operation steps In this test, three slightly damaged human hair bundles were selected. The combing force of the hair bundles before and after use was tested with a combing instrument. Each hair bundle was combed 5 times in a cycle, and the combing force value was recorded.

[0064] (3) Calculation formula

[0065] Where: C0—combing force of baseline test; Cs—combing force of sample treatment test; (4) Data analysis: Statistical analysis software was used to perform statistical analysis of the data. The statistical method adopted was two-tailed test, and the significance level was α=0.050. Descriptive statistics were performed on each group of data: quantity, mean, standard deviation, etc. The Shapiro-Wilk Test was used to test the significance of the normal distribution of the data improvement value. If Sig. (two-tailed)>0.050, it is normally distributed and a T test was performed. If Sig. (two-tailed)≤0.050, it is not normally distributed and a Wilcoxon test was performed. The comparison of the test samples before and after use was performed using paired samples T test or rank sum test. The comparison between the test product and the control group was performed using independent samples T test or rank sum test. All the above statistical analyses were two-tailed tests, and the significance level was α=0.05. “ns” indicates no statistical difference, P≥0.050; “*” indicates a significant difference: 0.010≤P<0.050, marked with “*”; 0.001≤P<0.010, marked with “**”; P<0.001, marked with “***”.

[0075] In summary, test two shows that, compared with before treatment, the combing power of the hair strands treated with the sample improved by 92.023% (mean before treatment 1.379 - mean after treatment - 0.110) ÷ mean before treatment 1.379 × 100%), indicating a significant difference between the two sets of data (significance factor P < 0.050). Furthermore, compared with before treatment, the combing power of the hair strands treated with the sample improved by 35.088% (mean before treatment 0.057 - mean after treatment 0.037) ÷ mean before treatment 0.057 × 100%, again showing a significant difference between the two sets of data (significance factor P < 0.050). This indicates that the sample has hair care effects.

[0076] Compared to existing technologies, the hair care composition of this application, through the synergistic effect of glutamic acid, rapeseed oil amide propyl dimethylamine, panthenol, and hydrolyzed wheat protein, solves the problem that existing hair care products struggle to simultaneously achieve good moisturizing effects and good combing ability when hair is wet. This composition forms a protective film on the hair surface, which not only locks in moisture and provides a moisturizing effect, but also reduces friction in wet hair, thereby improving hair smoothness and combability, and enhancing the user's combing experience when hair is wet.
