Description

Technical Field

[0001] This invention belongs to the field of daily chemical technology, specifically relating to a hair and scalp care composition, its preparation method, and its application. Background Technology

[0002] With increasing environmental pollution, frequent perming and dyeing, and rising lifestyle stress, problems such as damaged scalp barrier, dry and frizzy hair, breakage, and split ends are becoming increasingly common. Existing hair and scalp care products often focus on a single function: for example, they only focus on moisturizing the hair surface while neglecting scalp barrier repair; or they rely on chemical conditioners, which can easily cause scalp irritation with long-term use. At the same time, the active ingredients in traditional products lack synergy; for example, collagen alone is difficult for hair to absorb effectively, and plant extracts alone have short-lived effects. Existing product formulations lack targeted ratio design, making it difficult to simultaneously achieve the dual benefits of scalp care and hair nourishment.

[0003] Therefore, developing a care composition that combines scalp care and hair nourishment and is suitable for different scalp and hair types has become an urgent need for the industry. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of existing technologies and provide a hair and scalp care composition that achieves synergistic effects of scalp repair and hair nourishment through the combination of glycoproteins, hydrolyzed collagen, glycolipids, and tea extract. This invention also provides a method for preparing this care composition, a shampoo product containing the composition, and a method for preparing the same, resulting in products with good stability and gentle, non-irritating properties.

[0005] To achieve this objective, the present invention adopts the following technical solution: This invention provides a hair and scalp care composition, comprising the following components by weight: 0.5-15.0 parts of glycoprotein, 0.5-15.0 parts of hydrolyzed collagen, 0.3-10.0 parts of glycolipid, and 0.3-10.0 parts of tea extract.

[0006] This application addresses the technical problems of existing hair care products, such as single efficacy, poor ingredient synergy, scalp irritation, and poor absorption. It provides a hair and scalp care composition, in which four core ingredients—glycoprotein, hydrolyzed collagen, glycolipids, and tea extract—are combined to achieve synergistic effects. This combination simultaneously repairs the scalp barrier, deeply nourishes hair strands, and gently controls oil and provides antioxidant protection. Long-term use can improve dryness, frizz, breakage, and split ends, regulate scalp oil, and strengthen the scalp barrier function. The reasons for this are likely: glycoprotein forms a breathable protective film on the scalp, quickly repairing damaged barriers and locking in moisture; hydrolyzed collagen penetrates the gaps between hair cuticles, replenishing lost keratin and strengthening hair structure; glycolipids are derived from bio-fermentation, improving ingredient permeability and absorption efficiency, and are gentle, biodegradable, and non-irritating; tea extract is rich in tea polyphenols and catechins, scavenging free radicals, providing antioxidant protection, and soothing and controlling oil. The combination of these four ingredients creates a "barrier repair - structural replenishment - enhanced penetration and absorption - soothing and protective" effect, solving the problems of weak effects and poor absorption associated with single ingredients, and achieving synergistic care for both scalp and hair.

[0007] Furthermore, in the hair and scalp care composition, the glycoprotein is 7-15 parts, the hydrolyzed collagen is 5-10 parts, the glycolipid is 4-10 parts, and the tea extract is 5-8 parts.

[0008] Secondly, the present invention provides a method for preparing a hair and scalp care composition, comprising the following steps: mixing the glycoprotein, hydrolyzed collagen, glycolipid and the tea extract evenly to obtain the hair and scalp care composition.

[0009] Thirdly, the present invention provides the application of a hair and scalp care composition in a shampoo product.

[0010] Fourthly, the present invention provides a shampoo product comprising the hair and scalp care composition of claim 1 or 2, wherein the hair and scalp care composition comprises 1-35% by weight in the shampoo product.

[0011] Furthermore, in the hair and scalp care composition, the glycoprotein, the hydrolyzed collagen, the glycolipid, and the tea extract account for 0.5-15.0%, 0.5-15.0%, 0.3-10.0%, and 0.3-10.0% by weight, respectively, in the shampoo product.

[0012] Furthermore, the shampoo product also includes 1-25% surfactant, 0.5-5% thickener, 0.01-0.3% preservative, 0.01-1.0% pH adjuster, 0-1% fragrance, 0.1-1% conditioning agent, and the balance being water.

[0013] Furthermore, the shampoo product satisfies at least one of the following: (1) The surfactant includes one or more of the following: sodium C14-16 olefin sulfonate, sodium cocoamidopropionate, sodium lauroyl sarcosinate, sodium laureth sulfate, sodium cocoyl methyl taurate taurate or cocamidopropyl hydroxysulfonate. (2) The thickener includes one or more of cocamide DEA, cocamide methyl MEA, or sodium chloride; (3) The preservative includes one or more of phenoxyethanol, sodium benzoate, and benzyl alcohol; (4) The pH adjuster includes one or more of citric acid, sodium citrate, sodium hydroxide, and triethanolamine; (5) The conditioning agent includes one or more of guar hydroxypropyltrimethylammonium chloride, polyquaternium salt-10, and polyquaternium salt-22.

[0014] Fifthly, the present invention provides a method for preparing the shampoo product, comprising mixing the various components evenly to obtain the shampoo product.

[0015] Furthermore, the preparation method includes the following steps: (1) Mix water and the conditioner together and stir until evenly dispersed; (2) Add the surfactant, heat to 80-90℃, and stir for 30 minutes until completely dissolved; (3) Cool down to below 48°C, add the hair and scalp care composition, the preservative and the fragrance, and stir well; (4) Add the pH adjuster and the thickener to obtain the shampoo product.

[0016] Beneficial effects 1. Glycoproteins can form a breathable protective film on the scalp surface, repairing the damaged barrier and specifically alleviating different scalp problems such as oily and sensitive skin, and dry and damaged skin.

[0017] 2. Hydrolyzed collagen can penetrate into the gaps between hair cuticles, replenishing the keratin lost from the hair, and working with glycoproteins to effectively solve the problems of dry hair and breakage.

[0018] 3. The combination of glycoprotein, hydrolyzed collagen, glycolipid and tea extract shows significantly better efficacy than single or missing components in terms of stability, oil control and repair of the scalp barrier.

[0019] 4. All active ingredients are of natural origin or biodegradable, making them safe for people with sensitive skin. Detailed Implementation
