Description

Technical Field

[0001] The present invention belongs to the field of preparation of hair cleaning agents, and particularly relates to a functional hair cleaning agent and a preparation method thereof. Background Art

[0002] As an important part of daily care products, hair cleaning agents have shown remarkable development trends in terms of market scale, product functions, and consumption trends in recent years. According to relevant data, the market scale of China's hair care and washing market has increased from 43.39 billion yuan in 2017 to 65.5 billion yuan in 2023, and is expected to reach 82.79 billion yuan in 2027. This growth reflects the continuous increase in consumers' demand for hair care products, as well as the market's demand for high-quality and multi-functional products. However, market competition has also become increasingly fierce. International brands such as Procter & Gamble and Unilever dominate the market with their strong brand effects and mature product lines, while domestic brands are gradually emerging through differentiated competition. This competitive pattern has led to a relatively high market concentration and an increased entry threshold for new brands, and at the same time, the phenomenon of product homogenization is relatively prominent.

[0003] Consumers' demands for hair cleaning agents are becoming increasingly diverse and personalized. With the improvement of living standards, consumers are no longer satisfied with the traditional cleaning function, but put forward higher requirements for the efficacy, safety, and environmental protection of products. For example, shampoos targeting scalp health problems (such as hair loss, dandruff, greasiness, etc.) have become a market hot spot. In addition, consumers' preference for products with natural plant ingredients and no added chemical substances has promoted the industry's development towards the green and natural direction. However, this has also brought new problems. For example, some products may sacrifice cleaning effect or stability when pursuing natural ingredients, resulting in difficult-to-balance product performance.

[0004] The multifunctional hair cleaning agent of the present application can effectively solve many problems faced by the current hair cleaning agent market through innovative formula design and ingredient optimization. First, aiming at the problem of single function of traditional shampoos, this product combines multiple functions such as cleaning, conditioning, repairing, and antibacterial. It is not only suitable for the daily care of human hair, but also can meet the special needs of pet hair. For example, for pet hair, mild ingredients suitable for pet skin are added to its formula, which can reduce hair knotting and dandruff problems while cleaning, providing comprehensive care for pets. The multifunctional hair cleaning agent pays attention to naturalness and safety in ingredient selection, avoiding the possible irritation or allergy problems caused by common chemical additives in traditional shampoos. A variety of natural plant extracts and bioactive ingredients are used in its formula, which not only ensures the mildness of the product, but also improves its repair ability for damaged hair. In addition, the product also achieves better cleaning effect and conditioning performance by optimizing the ratio of surfactants, solving the problems of insufficient cleaning power or poor conditioning effect of some products in the market. Summary of the Invention

[0005] To solve the above technical problems, the present invention provides a functional hair cleaning agent and a preparation method thereof:

[0006] Step 1: Cut the stems and leaves of Suaeda glauca into pieces and mix them with 85% - 95% ethanol, soak them at 40 - 65°C at 400 - 800 r / min for 20 - 40 h, then put them into an ultrasonic extractor for ultrasonic treatment for 60

[0007] - 120 min and then filter. Add the filtered solid residue to 60% - 75% ethanol for ultrasonic treatment for 60 - 120 min and filter. Concentrate the filtrate obtained from the two treatments under reduced pressure until there is no ethanol smell, and purify and concentrate it through a microfiltration membrane and a reverse osmosis membrane to obtain a Suaeda glauca extract;

[0008] Step 2: Soak raw Platycladus orientalis leaves, Polygonum multiflorum, dried ginseng, Gleditsia sinensis, ginger, Eclipta prostrata, Speranskia tuberculata, and Ligustrum lucidum in ultrapure water for 10 - 15 h, heat at 50 - 70°C for 3 - 5 h, raise the temperature to 100 - 120°C and heat for 3 - 6 h, cool and filter. Concentrate the filtrate at 50 - 70°C to 1 / 4 - 1 / 8 of the mass of the added ultrapure water to obtain a conditioning concentrate;

[0009] Step 3: Add sodium lauryl polyoxyethylene sulfate, ammonium lauryl polyoxyethylene sulfate, sodium chloride, and ethylene glycol distearate to ultrapure water, stir evenly and heat to 70 - 90°C, then add the conditioning concentrate and continue heating for 30 - 120 min, and cool to room temperature;

[0010] Step 4: Add guar gum, polydimethylsiloxane, and phenoxyethanol to the product of Step 3 after cooling, stir evenly, add the Suaeda glauca extract, adjust the pH to about 6 with citric acid, stir evenly, defoam and let it stand to obtain the functional hair cleaning agent.

[0011] Furthermore, the mass ratio of the stems and leaves of Suaeda glauca to ethanol in Step 1 is 1:8 - 15.

[0012] Furthermore, the mass ratio of raw Platycladus orientalis leaves, Polygonum multiflorum, dried ginseng, Gleditsia sinensis, ginger, Eclipta prostrata, Speranskia tuberculata, Ligustrum lucidum to ultrapure water in Step 2 is 0.1:0.04 - 0.06:0.02 - 0.045:0.06 - 0.075:0.05 - 0.08:0.035 - 0.056:0.02 - 0.035:0.025 - 0.035:5 - 12.

[0013] Further, in terms of mass ratio, the raw materials in Step 3 are as follows: sodium lauryl polyoxyethylene ether sulfate: ammonium lauryl polyoxyethylene ether sulfate: sodium chloride: ethylene glycol distearate: conditioning concentrate: ultrapure water = 0.05 - 0.12: 0.02 - 0.06: 0.015 - 0.03: 0.015 - 0.03: 0.07 - 0.12: 0.45 - 0.7.

[0014] Further, in terms of mass ratio, the raw materials in Step 4 are as follows: sodium lauryl polyoxyethylene ether sulfate in Step 3: guar gum: polydimethylsiloxane: phenoxyethanol: Suaeda glauca extract

[0015] = 0.05 - 0.12: 0.005 - 0.02: 0.01 - 0.03: 0.1 - 0.15.

[0016] The beneficial effects of the present invention are as follows. Through multi-step fine design of the preparation method of the present invention, the multi-functionality and high efficiency of the hair cleaning agent are realized. First, in the process of extracting the Suaeda glauca extract, the method of mixing ethanol with ultrasonic treatment can efficiently extract the active ingredients in Suaeda glauca, such as flavonoids, polyphenols, etc. These ingredients have the functions of antioxidant, anti-inflammatory and nourishing the scalp. At the same time, through the purification and concentration of the microfiltration membrane and reverse osmosis membrane, the purity and stability of the extract are ensured. The Suaeda glauca extract contains a variety of active ingredients, such as flavonoids, polysaccharides, pigments, etc. These ingredients endow the extract with significant antioxidant, anti-inflammatory, nourishing and scalp microenvironment regulating abilities. The flavonoid compounds in Suaeda glauca have strong antioxidant and anti-inflammatory effects, can effectively scavenge free radicals, inhibit oxidative stress reactions, and thus reduce scalp inflammation and hair follicle damage. In addition, Suaeda glauca polysaccharides have the functions of regulating immunity and promoting cell repair, can enhance the natural barrier function of the scalp, and improve scalp health. The synergistic effect of these ingredients enables the Suaeda glauca extract in the hair cleaning agent not only to clean the hair, but also to deeply nourish the scalp and promote hair follicle health. In addition, the Suaeda glauca extract also contains rich unsaturated fatty acids, such as linoleic acid. These ingredients can moisten the hair and reduce hair dryness and breakage. The application of the Suaeda glauca extract in the hair cleaning agent can not only provide a cleaning function, but also improve scalp health, promote hair growth and care through its antioxidant, anti-inflammatory, nourishing and repairing effects. It is a natural plant extract with significant advantages.

[0017] Secondly, in the preparation process of the conditioning concentrate, through multiple heating processes, the nutritional components in traditional Chinese medicines such as Platycladus orientalis (L.) Franco and Polygonum multiflorum Thunb. are fully extracted. These components can deeply condition the hair, enhance the toughness of the hair, reduce breakage and split ends, and at the same time promote scalp health.

[0018] In the formulation design, the present invention combines a variety of surfactants and conditioners, such as sodium lauryl polyoxyethylene sulfate, guar gum, polydimethylsiloxane, etc. These components act synergistically to not only provide good cleaning effects but also form a protective film on the hair surface, reduce static electricity generation, and make the hair smoother and easier to comb. In addition, by adding phenoxyethanol as a preservative and using citric acid to adjust the pH to be close to the physiological pH value of the scalp, the safety and stability of the product are further improved. This comprehensive formulation design and preparation process enable the hair cleaning agent of the present invention to not only effectively clean the hair but also nourish the scalp, repair damaged hair, and is applicable to the care of both human and pet hair, having broad market application prospects and significant innovation advantages.

[0066]

[0067] As can be seen from the data in Table 1, from the test data results, it can be seen that from the foam effect, the foaming effect of Example 1 is the best. The generated foam is arranged compactly, the foam is delicate and dense, and the foam stability coefficient is high. In contrast, although Examples 2 and 3 are slightly inferior in terms of the foam stability coefficient, their foam quality exceeds that of the comparative examples, showing obvious performance advantages.

[0068] Hair and scalp conditions: Six people with similar hair quality and the same length were selected and divided into six groups. Examples 1 to 3 and Comparative Examples 1 to 3 were used to wash their hair respectively. After two weeks of washing their hair, observations were recorded.

[0069] Table 2 Hair growth test data of Examples 1 to 3 and Comparative Examples 1 to 3

[0070]

[0071] As can be seen from Table 2, the hair growth of Examples 1 to 3 is flat, shiny, black and bright, smooth and the dandruff is hardly noticeable. The hair follicle openings are clear and evenly distributed, which is better than that of the comparative examples. This shows that the adopted formula and preparation process have significant advantages and effects in improving hair and scalp health. Specifically, the specific ingredient combinations and optimized process conditions used in Examples 1 to 3 can not only effectively nourish the hair, enhance its luster and softness, but also significantly improve the scalp environment, reduce the generation of dandruff, and promote the healthy growth of hair follicles. The realization of this comprehensive effect is attributed to the synergistic effect of the natural plant extracts, nutritional components and functional additives contained in the formula. These components act together on the hair and scalp, providing sufficient nutrition for the hair, and at the same time regulating the microenvironment of the scalp to make it more suitable for the growth and development of hair follicles. In addition, the optimized preparation process ensures the stability and bioavailability of these components, enabling them to play a better role. In contrast, due to the lack of key components or insufficient process optimization in the comparative examples, such significant improvement effects cannot be achieved. Therefore, the success of Examples 1 to 3 demonstrates the innovation and practicality of this formula and process in the field of hair care, providing a strong scientific basis and practical guidance for the development of high-performance hair care products.
