Description

Technical Field

[0001] This invention belongs to the field of shampoo composition technology, specifically, it relates to a method for preparing a plant composition with hair-nourishing effects. Background Technology

[0002] Shampoo is considered one of the most commonly used cosmetics for daily hair and scalp cleaning, and its use is suitable for men and women of all ages. The function of shampoo is to effectively and thoroughly remove dirt, excess sebum, or other oils. Hair care is increasingly valued, but some common hair or scalp problems, such as excessive oil secretion, dandruff, or dry and split ends, continue to bother people.

[0003] Most shampoos on the market currently use antifungal agents (such as zinc pyrithione ZPT) as dandruff removers, including salicylic acid, zinc pyrithione, piroctone olamine salt, clomiphene, etc. These dandruff removers are all chemical dandruff removers, which have problems such as sensitization, irritation and instability, and can cause significant damage to the hair cuticle, resulting in dry and split ends after long-term use, especially on hair damaged by perming and dyeing.

[0004] Shampoos often have limited functionality and lack conditioning benefits. Synthetic shampoos contain toxic chemicals such as parabens and sodium lauryl sulfate, which can damage hair. It's important to avoid using shampoos with other hair care products to prevent the formation of harmful substances, such as ingredients that co-produce carcinogenic compounds (like benzene). Shampoo foam contains washed-out dirt, which is difficult to rinse off and can redeposit on the hair, reducing cleaning quality. Excessive microbial growth is also a concern: in hot and humid summers, sweat, sebum, moisture from the air, and pollutants on the scalp, combined with the hair covering it, create a breeding ground for microorganisms, easily leading to scalp inflammation. Summary of the Invention

[0005] The purpose of this invention is to provide a method for preparing a plant composition with hair-nourishing effects. Modified starch is loaded with resveratrol and compound plant extracts to obtain a modified Pickering emulsion, allowing the plant extracts to function better in the system and promoting scalp absorption. The plant extracts can remain on the hair, achieving a long-lasting protective effect, while the scalp can absorb nourishing ingredients and strengthen scalp health. A sodium cocoyl glycinate system is mixed with a tea saponin surfactant to obtain a compound surfactant system. The combination of tea saponin and sodium cocoyl glycinate forms a surfactant system with stable performance, moderate viscosity, rich and delicate foam, and gentle, non-irritating properties. Goat milk components are added; the α-hydroxy acids, vitamins, and minerals in goat milk contribute to cell nutrition and enhance hair quality. By adding goat milk and some plant extracts for synergistic effects, and using stabilizers, the viscosity and stability of the system are increased, inhibiting protein denaturation in goat milk and the stability of the plant extract components.

[0006] The technical problems this invention aims to solve are: shampoos have limited functionality and lack conditioning effects; consumers tend to prefer chemical ingredients that may harm their health; synthetic shampoos contain toxic chemicals that can damage hair; the foam produced by shampoo contains washed-out dirt, and the dirt remaining in the foam is difficult to rinse off and redeposits on the hair, reducing the cleaning quality; and harmful microorganisms proliferate excessively: in the hot and humid summer, sweat, sebum, moisture in the air, and pollutants on the scalp, combined with the cover of hair, make the scalp a breeding ground for microorganisms, easily causing scalp inflammation.

[0007] The objective of this invention can be achieved through the following technical solutions:

[0008] A plant-based composition with hair-nourishing effects comprises the following raw materials in parts by weight: 30-40 parts modified Pickering emulsion, 15-25 parts compound surfactant system, 15-30 parts goat milk, 1-3 parts avocado seed extract, 5-7 parts hydroxypropyl methylcellulose and 80-100 parts deionized water;

[0009] The compound surfactant system includes a sodium cocoyl glycinate system and a tea saponin surfactant;

[0010] Furthermore, the modified Pickering emulsion is prepared by loading resveratrol and compound plant extracts onto modified starch, and the preparation method is as follows:

[0011] Caprylic / capric triacetate and glyceryl triacetate were mixed with hydrogenated castor oil at a mass ratio of 1:1 and stirred at room temperature for 10 min to form an oil phase. Resveratrol and compound plant extracts were added to the oil phase at 50°C and 400 rpm and stirred for 30 min. Octenyl succinic anhydride modified starch and glycerol were dispersed in deionized water (68%, w / w) and added to the oil phase while stirring at 1500 rpm. The dispersion was then treated with a high-pressure homogenizer at a pressure of 500 Bar to obtain a modified Pickering emulsion.

[0012] Furthermore, the compound plant extracts include carvacrol, fermented cyclosporine extract, Ganoderma lucidum extract, ginger extract, and Platycladus orientalis leaf extract.

[0013] Furthermore, the ratio of resveratrol to compound plant extract is (0.1-0.3):(0.6-1).

[0014] Furthermore, the ratio of octenyl succinic anhydride modified starch, glycerol, and deionized water is (0.5-1.5):(2-4):(66-70).

[0015] Furthermore, the preparation method of *Gynostemma pentaphyllum* extract is as follows:

[0016] The leaves of *Rhizophora stylosa* were dried in a hot air furnace at 60°C, pulverized with a mortar and pestle, and then autoclaved with 8% sucrose solution and deionized water in a ratio of 0.5:1:10. The mixture was then inoculated with 10% *Lactobacillus plantarum* and cultured in MRS medium and Sharpe (MRS) broth for lactic acid bacteria. After fermentation at 37°C and 80 rpm for 5 days in a stirrer, the fermented *Rhizophora stylosa* extract was obtained by centrifugation at 8000 rpm for 30 min.

[0017] Furthermore, the ratio of the amount of *Gynostemma pentaphyllum* leaves, sucrose solution, and deionized water is (0.3-0.7):(0.5-1.5):(8-12).

[0018] Furthermore, the compound surfactant system is composed of a sodium cocoyl glycinate system and a tea saponin surfactant, and its preparation method is as follows:

[0019] A1. Deionized water, glycerol, disodium EDTA, and sodium cocoyl glycinate were mixed to obtain phase A. Sodium methyl cocoyl taurate, tris(cetearyl alcohol polyether-4) phosphate, and ethylene glycol distearate were mixed to obtain phase B. Citric acid, phenoxyethanol, and ethylhexylglycerin were mixed to obtain phase C. Phase C was placed in a constant temperature water bath with phases A and B and emulsified and homogenized for 30 minutes at an emulsification rate of 1200 r / min until completely dissolved. Then, the mixture was placed in a cold water bath and stirred. After standing for 24 h, the sodium cocoyl glycinate system was obtained.

[0020] A2. The sodium cocoyl glycinate system was mixed with the tea saponin surfactant to obtain a composite surfactant system.

[0021] Furthermore, in phase A, the ratio of deionized water, glycerol, disodium EDTA, and sodium cocoyl glycinate is 9.6:25:0.1:55; in phase B, the ratio of sodium methyl cocoyl taurate, tris(cetearyl alcohol polyether-4) phosphate, and ethylene glycol distearate is 5:1:2; and in phase C, the ratio of citric acid, phenoxyethanol, and ethylhexylglycerin is 1.5:0.8.

[0022] A plant-based composition with hair-nourishing properties, comprising the following steps:

[0023] S1. Add the modified Pickering emulsion to deionized water and stir evenly at 45°C to obtain a mixture;

[0024] S2. Add the compound surfactant system, goat milk, avocado seed extract and hydroxypropyl methylcellulose to the mixture and stir until homogeneous to obtain the composition.

[0025] Beneficial effects of the present invention

[0026] (1) In the technical solution of the present invention, carvacrol has the effect of removing mites, and phenolic substances themselves have antibacterial effects; Platycladus orientalis leaf extract promotes the proliferation of human dermal papilla cells, prolongs the growth period of hair follicles, and has a good anti-hair loss effect; ginger extract has the effect of inhibiting reductase, and shampoo prepared with ginger extract has a certain anti-hair loss effect; Ganoderma lucidum has a good affinity for hair, not only will it not cause antigen-antibody reaction, but its nutrients can also be absorbed by hair and penetrate into the stratum corneum, making hair shiny and playing a role in beautifying and protecting hair; the compound plant extract achieves the sun protection and anti-hair loss effect on the scalp and hair through different methods.

[0027] (2) In the technical solution of the present invention, modified starch is used to load resveratrol, carvacrol, fermented cyclosporine extract, Ganoderma lucidum extract, ginger extract, and Platycladus orientalis leaf extract, so that the plant extracts can play a better role in the system and promote the absorption of plant extracts by the scalp. Among them, the plant extracts can stay on the hair to achieve a long-lasting protective effect, and the scalp can absorb nourishing ingredients to strengthen scalp health. Using modified starch to load other water-insoluble components in resveratrol and plant extracts reduces the addition of surfactants and reduces the irritation of surfactants to the scalp. In addition, modified starch also has a good moisturizing effect on hair and an anti-itch effect on skin.

[0028] (3) In the technical solution of the present invention, tea saponin has the functions of cleaning, moisturizing and anti-ultraviolet rays. At the same time, it can reduce inflammation and itch, remove dandruff, and is compounded with a sodium cocoyl glycinate surfactant system with a pH value close to that of the scalp. It has extremely low irritation, good foaming effect and cleaning ability, and will not take away the moisture of the scalp, causing a tight feeling. The tea saponin and the sodium cocoyl glycinate system are compounded to form a surfactant system with stable performance, moderate viscosity, rich and delicate foam, and mild and non-irritating properties.

[0029] (4) In the technical solution of the present invention, the compound surfactant and the modified Pickering emulsion work together to achieve a mild and effective detergency.

[0030] (5) In the technical solution of this invention, the α-hydroxy acids, vitamins, and minerals in goat milk help with cell nutrition and enhance hair quality. Goat milk also helps stabilize the pH value of the system. pH is responsible for improving hair quality and minimizing eye irritation, as well as stabilizing the ecological balance of the scalp. The mild acidity prevents swelling and promotes scale settling, thereby inducing hair shine and minimizing hair damage. Furthermore, the addition of goat milk improves the dispersion of dirt, ensuring that there is no dirt in the foam.

[0031] (6) In the technical solution of the present invention, by adding goat milk and some plant extracts for synergy, and using stabilizers, the viscosity and stability of the system are increased, the denaturation of proteins in goat milk and the stability of plant extract components are inhibited, the addition of goat milk reduces the surface tension and viscosity of shampoo, and provides good conditioning performance, good cleaning ability, foaming stability, wetting time and brightness.
