Description

Technical Field

[0001] This invention belongs to the field of daily chemical products technology, specifically relating to a herbal compound shampoo composition. More specifically, it relates to a herbal compound shampoo composition with 16 kinds of natural herbal medicines as the core, combined with a mild excipient system, and prepared through a specific decoction-then-add process. It has multiple effects such as darkening hair, strengthening hair, relieving itching, removing dandruff, and nourishing the scalp. It is suitable for all types of scalp people, especially those with sensitive scalps, dry and frizzy hair, hair loss, dandruff, and premature graying of hair. Background Technology

[0002] With the fast pace of life, changes in dietary structure, and the influence of environmental factors, scalp health problems are becoming increasingly prominent, with hair loss, dandruff, scalp itching, and premature graying of hair troubling more and more people. Currently, there are many types of shampoos on the market, mainly divided into two categories: chemically synthesized and herbal.

[0003] Chemically synthesized shampoos typically contain irritating ingredients such as sulfates and parabens. While they offer strong cleaning power and good foaming, long-term use can damage the scalp barrier, leading to increased scalp sensitivity, dryness, and itching, and even exacerbating hair loss. Furthermore, these shampoos often focus solely on cleaning, making it difficult to address the multiple needs of hair growth, strengthening, and scalp care. Some products also leave residues, posing potential health risks.

[0004] Herbal shampoos, made with natural herbal ingredients, are gentle and non-irritating, and are gradually gaining popularity among consumers. However, existing herbal shampoos generally have the following drawbacks: First, the formula design is unreasonable, mostly consisting of simple herbal ingredients piled up, failing to follow the traditional Chinese medicine principle of "principal, assistant, adjuvant, and guide" in the formulation. As a result, the effects of each ingredient cannot work synergistically, leading to poor effects in darkening hair, strengthening hair, relieving itching, and removing dandruff, making it difficult to solve scalp and hair problems from the root. Secondly, the preparation process is crude, mostly using simple soaking and decoction methods, without distinguishing the characteristics of medicinal materials to design the process of decocting first and adding later, resulting in insufficient extraction of effective ingredients from herbal raw materials, and loss of some volatile and easily damaged effective ingredients, affecting the efficacy of the product; in addition, the filtration process is simple, and the product is prone to turbidity and suspended matter, affecting the user experience and stability. Third, the excipient system is not properly matched. In order to pursue foaming and stability, some products add too many irritating excipients, which violates the core advantage of herbal products being gentle. In addition, some products have problems such as short shelf life, uneven texture, and easy separation. At the same time, most products are not strong enough to resist hard water, and their cleaning effect and foaming ability are significantly reduced when used in hard water areas. Fourth, the lack of strict quality control standards in the production process and the absence of clear operational red lines for key processes have led to large quality differences between product batches and poor efficacy stability.

[0005] Soapberry and soapberry, as traditional natural cleaning ingredients, contain natural saponins that have excellent cleaning effects and are gentle and non-irritating. Their use for cleansing and skincare was recorded as early as the *Compendium of Materia Medica*, and modern research has also confirmed their ability to regulate scalp sebum secretion and reduce dandruff. Sophora flavescens and Cnidium monnieri have significant antibacterial and antipruritic effects; their matrine and osthol components can inhibit the growth and reproduction of various dermatophytes and relieve scalp itching. Eclipta prostrata and Ligustrum lucidum are a classic combination for darkening and strengthening hair; both are associated with the liver and kidney meridians, nourishing the liver and kidneys and promoting melanin synthesis, thus improving premature graying of hair. Arborvitae leaves, pine needles, and Spatholobus suberectus can invigorate blood circulation, nourish the scalp, enhance hair follicle vitality, and reduce hair loss.

[0006] Based on this, developing a shampoo composition with a scientific formula, reasonable process, comprehensive efficacy, full retention of effective herbal ingredients, gentle and non-irritating properties, strong resistance to hard water, and multiple functions such as hair darkening, hair strengthening, itch relief, dandruff removal, and scalp nourishment, to solve many defects of existing shampoo products, has become an urgent technical problem to be solved in the current daily chemical industry. Summary of the Invention

[0007] The purpose of this invention is to overcome the shortcomings of existing herbal shampoos, such as unreasonable formulas, rough processes, single efficacy, unstable quality, strong irritation, and insufficient resistance to hard water.

[0044] (4) Albizia bark (160-260g): It is an adjuvant herb with a sweet taste and neutral nature. It enters the heart, liver and lung meridians. It contains effective ingredients such as albizia glycoside and volatile oil. The volatile oil is easily volatilized and needs to be extracted later. It has the effects of relieving depression and calming the mind, promoting blood circulation and reducing swelling. It can soothe the nerves of the scalp, relieve scalp tension and itching, promote scalp blood circulation, help nourish hair follicles, reduce hair loss, and harmonize the medicinal properties of the herbs added later. It works synergistically with the raw licorice root in the first decoction group to further harmonize the medicinal properties of the whole formula and enhance the mildness of the product. In the herbal formula of this invention, the herbs in the first decoction group are mostly hard in texture, with active ingredients that are difficult to dissolve or require long-term decoction to be fully extracted. A 3-hour soaking followed by a 1-hour gentle simmering decoction allows for the full extraction of their active ingredients. The herbs in the subsequent decoction group mostly contain volatile active ingredients. If they are decocted together with the first decoction group for a long time, the active ingredients will evaporate and be lost, reducing the product's efficacy. Therefore, a subsequent decoction process is adopted: after the extraction of the first decoction group, the herbs are briefly boiled for 5 minutes, followed by a 1-hour steeping. This process not only fully dissolves the active ingredients but also prevents their evaporation, ensuring that the efficacy of each herb is fully realized. Simultaneously, the 16 herbs work synergistically to achieve multiple effects such as hair darkening, hair strengthening, itch relief, dandruff removal, and scalp nourishment, with a mild medicinal nature and no obvious irritation.

[0045] (II) Functions and compatibility principles of the excipient system The excipient system of this invention selects mild and safe ingredients, and is scientifically and rationally combined. It can not only help improve the user experience and stability of the product, but also avoid irritating the scalp and hair. In synergy with herbal extracts, it further enhances the moisturizing, repairing and cleansing effects of the product, as detailed below: Surfactants: Alkyl glycoside-0810 (APG-0810), cocoaminopropyl betaine (CAB), sodium cocoyl glutamate, and sodium fatty alcohol polyoxyethylene ether sulfate (AES) are selected for compound use. Alkyl glycoside-0810 (APG-0810) is a short-chain alkyl glycoside with strong penetrating power, easy solubility in cold water, alkali and salt resistance, mild and non-irritating, and has good biodegradability. It can assist herbal extracts in enhancing the cleansing effect while protecting the scalp barrier. Cocoaminopropyl betaine (CAB) is an amphoteric surfactant with excellent mildness, superior foaming properties, and hard water resistance, significantly improving the product's performance in hard water areas. It also reduces the irritation of other surfactants, resulting in finer and denser foam. Sodium cocoyl glutamate is an amino acid surfactant, gentle and skin-friendly, reducing irritation, improving the product's foaming and cleansing power, and also providing some moisturizing effect. Sodium fatty alcohol polyoxyethylene ether sulfate (AES)... As anionic surfactants, they can enhance the foaming and cleaning power of the product. The combination of these four ingredients can ensure the cleaning effect and foaming performance of the product, while also ensuring that the product is gentle and non-irritating, and has excellent hard water resistance. This solves the problems of low foam, insufficient cleaning power and poor hard water resistance in pure Chinese herbal shampoos, while avoiding the strong irritation of chemical surfactants.

[0046] Thickening system: Hydroxyethyl cellulose (HEC) and sodium chloride are used in combination. Hydroxyethyl cellulose (HEC) has good thickening, suspending and stabilizing effects, which can increase the viscosity of the product, make the product texture uniform, avoid separation, and at the same time have a certain moisturizing effect, which can reduce the loss of scalp moisture. Sodium chloride can assist hydroxyethyl cellulose in enhancing the thickening effect, adjust the viscosity of the product, and make the product achieve a suitable texture for use. The combination of the two has a stable thickening effect and will not affect the mildness of the product or the efficacy of other ingredients, thus solving the problem of uneven texture and easy separation of herbal shampoos.

[0047] Preservative System: A multi-layered preservative system is formed by combining phenoxyethanol, ethylhexylglycerin, pentylene glycol, and potassium sorbate. This system effectively inhibits the growth and reproduction of bacteria, mold, and other microorganisms, extending the product's shelf life while being gentle and non-irritating, causing no damage to the scalp. The combination of phenoxyethanol and ethylhexylglycerin synergistically enhances the preservative effect and also provides some moisturizing benefits. Pentylene glycol enhances both the preservative effect and the product's moisturizing properties. Potassium sorbate, a natural preservative, is safe and gentle, further improving the product's safety. This system solves the problem of short shelf life and easy spoilage in pure herbal shampoos, ensuring the product can be stored stably at room temperature while avoiding the use of harmful preservatives.

[0048] Moisturizing and Repairing System: This system combines panthenol and squalane. Panthenol penetrates deep into the scalp and hair to replenish moisture and nutrients, repairing damaged scalp barriers and hair cuticles, improving dry scalp and frizzy hair, and enhancing hair resilience and shine. Squalane has good compatibility with human skin, forming a protective film on the scalp and hair surface to lock in moisture and nutrients, reducing damage from external stimuli, and nourishing the scalp while promoting healthy hair follicles. The combination of these two ingredients synergistically enhances the moisturizing and repairing effects, effectively improving dry scalp and hair, improving the product's nourishing effect, and solving the problem of poor moisturizing effect and dry hair after washing with herbal shampoos.

[0049] Optional additives: Hydrogenated castor oil (CO40) enhances essential oil solubility and optimizes product texture; Disodium EDTA acts as a chelating agent, binding metal ions in water to prevent them from affecting product stability and extending shelf life; Fragrances / essential oils mask the odor of herbal ingredients, improving the user experience, while some essential oils also have the effect of nourishing the scalp and relieving itching; Piroctone ketone ethanolamine (OCT) enhances dandruff and anti-itch effects; Polyquaternium-10 is a cationic polymer that adsorbs onto the hair surface to form a uniform protective film, reducing static electricity, improving hair combability in both dry and wet conditions, enhancing hair smoothness and shine, and reducing tangles and breakage. Users can choose to add these ingredients according to their needs, increasing product flexibility.

[0075] Comprehensive Description of Examples Coverage of formulation: Examples 1-5 fully cover the protection scope of all parameters in the claims of this invention, verifying the effectiveness and safety of the products under different formulations.

[0076] Scene adaptability: Example 1: Universal type, suitable for daily use by the vast majority of people; Example 2: Mild type, suitable for extremely sensitive scalps, infants, and pregnant women; Example 3: Enhanced version, suitable for people with severe dandruff, seborrheic alopecia, and severe scalp itching; Example 4: Hard water specific type, suitable for northern regions and areas with hard water; Example 5: Hair darkening special type, suitable for people whose main concern is premature graying of hair; Consistency verification: All embodiments strictly follow the decoction-then-add process and mandatory red line requirements of this invention, and the quality of the product is stable between batches, with efficacy differences within a reasonable range; Safety verification: The incidence of adverse reactions in all embodiments was 0%, proving that the formula of the present invention is mild and non-irritating, and suitable for long-term use; Comparative testing (verifying the technical advantages of this invention) To further verify the advantages of the present invention, a comparative test was set up. Example 1 of the present invention (optimal universal ratio) was selected as the experimental group and compared with two mainstream shampoo products on the market to test various effects and user experience, ensuring that the test conditions were uniform and the results were objective.

[0077] (a) Test Sample Experimental group: The herbal compound shampoo composition prepared in Example 1 of this invention; Control group 1: Commercially available chemically synthesized shampoos (containing sulfates and parabens preservatives, primarily for cleaning and dandruff removal); Control group 2: Commercially available ordinary herbal shampoo (containing 5 kinds of herbal ingredients, without the pre-decoction process, without cocoyl aminopropyl betaine, mainly for its gentle and hair-strengthening effects).

[0078] (II) Test Subjects and Conditions Ninety volunteers were selected and divided into three groups of 30 each (15 men and 15 women), aged 22 to 55 years. All volunteers had problems such as scalp itching, dandruff, and hair loss, and their scalp condition and the severity of their problems were basically the same. Among them, 15 volunteers in each group came from hard water areas (water hardness > 250 mg / L).

[0079] All three groups of volunteers used the product three times a week, with the same application method each time (apply to wet hair, massage for 3-5 minutes, then rinse), for a total of 8 weeks, and all indicators were recorded uniformly.

[0080] (III) Comparison of test results

[0081] (iv) Conclusions of the comparative test Comprehensive Superiority in Core Efficacy: The experimental group significantly outperformed the two control groups in core efficacy aspects such as relieving itching, removing dandruff, strengthening hair, darkening hair, and repairing the scalp barrier. The advantages in strengthening and darkening hair were most pronounced, exceeding the control groups by 22 and 37.3 percentage points respectively. This demonstrates that the 16-herb formula and the pre-decoction extraction process of this invention can fully exert synergistic effects, addressing scalp problems at their root.

[0082] Breakthrough improvement in hard water resistance: The user satisfaction rate in the experimental group (in areas with hard water) reached 100%, while that in the control group (2) was only 46.7%. This is due to the compound system of cocoyl aminopropyl betaine (CAB) and existing surfactants in this invention, which effectively solves the industry pain points of traditional herbal shampoos in hard water, such as easy formation of soap scum, drastic reduction in foam volume, and decreased cleaning power.

[0083] Product texture and user experience have been significantly improved: The 200-300 mesh coarse filtration + 400-500 mesh fine filtration gradation filtration process adopted in this invention completely solves the problems of ordinary herbal shampoos being prone to turbidity and sedimentation, resulting in a clear and transparent product; at the same time, the optimized surfactant compound makes the foam more delicate and dense, and polyquaternium-10 significantly improves the combability and smoothness of hair, reduces static electricity, and leaves hair smooth and shiny after washing, without dryness or residue, achieving 100% user satisfaction.

[0084] Significant safety advantages: The incidence of adverse reactions in the experimental group was 0%, far lower than the 20% in control group 1 and 6.7% in control group 2. This invention does not contain irritating ingredients such as sulfates and parabens, and the pH value of the finished product is strictly controlled between 4.5 and 6.5, which is highly compatible with the pH value of human scalp, effectively protecting the scalp barrier and suitable for long-term use by all types of people.

[0085] In summary, this invention achieves multiple synergistic effects through scientific herbal formulation, a unique decoction-then-add process, an optimized surfactant compound system, and a refined graded filtration process. Compared with existing commercially available products, it has significant advantages in efficacy, gentleness, hard water resistance, and user experience, effectively solving many defects of existing shampoos, such as single efficacy, strong irritation, unstable quality, insufficient extraction of effective ingredients, and insufficient hard water resistance.
