Description

Technical Field

[0001] The invention belongs to the technical field of shampoo soaps, and particularly relates to a shampoo soap capable of promoting hair growth and a preparation method thereof. Background Art

[0002] In modern society, with the accelerated pace of life and increasing pressure, hair loss is becoming more and more common, seriously affecting people's quality of life and mental health. As a result, the market demand for hair growth products continues to grow. Currently, a large number of hair growth-related products have emerged on the market.

[0003] Numerous studies on topical Chinese herbal liquids have focused on the selection and compatibility of various Chinese medicinal materials. However, existing Chinese herbal liquids still face numerous problems in practical application. For one thing, while many liquids claim to moisturize and improve hair quality, the actual results are poor. They have limited effects in nourishing hair and reducing dryness, and cannot fundamentally change the dryness and frizziness caused by lack of nutrition and moisture. Furthermore, while some liquids claim to promote hair growth, the actual results are poor, with low hair growth efficiency or even failure to achieve the intended purpose.

[0004] Shampoo bars, another common hair cleansing and care product, have also seen continued growth in recent years. Natural soaps are favored by consumers for their gentle cleansing properties, but traditional natural soaps often leave hair dry and frizzy after use. To address this issue, some manufacturers have experimented with adding various hair-care ingredients, such as oils and plant extracts, to shampoo bars. However, current shampoo bars on the market still lack the ability to balance cleansing and hair-care benefits. While some shampoo bars offer strong cleansing capabilities, they also excessively remove oils from the scalp and hair, causing hair to lose its natural protective barrier and become dry and brittle. Even with added hair-care ingredients, these ingredients struggle to retain and function effectively during the cleansing process, failing to achieve the desired hair-care effect. Regarding hair-promoting properties, the claims of most shampoo bars remain at a conceptual level, lacking scientifically validated formulas and clinical validation. The so-called hair-promoting ingredients often fail to truly promote hair growth.

[0005] In summary, existing external Chinese herbal medicines and shampoo soaps have obvious defects in key functions such as moisturizing, protecting and promoting hair growth, and cannot fully meet consumers' needs for healthy hair care. There is an urgent need to develop new products with better effects. Summary of the Invention

[0029] The present invention also provides the use of the external Chinese medicinal liquid or the preparation method in preparing a shampoo product, wherein the shampoo product includes a shampoo soap.

[0030] The present invention also provides a shampoo soap capable of promoting hair growth. The raw materials of the shampoo soap include the above-mentioned external Chinese medicine liquid and soap base raw materials; the soap base raw materials include the following raw materials in parts by weight: 470-530 parts of oil raw materials, 212-235 parts of alkali liquid raw materials, 290-310 parts of alcohol mixed liquid and 120-130 parts of sugar liquid.

[0031] In the field of traditional Chinese medicine, cypress seeds are primarily used internally to nourish the heart and soothe the mind, as well as to moisturize the intestines. This invention directly adds oil-rich cypress seeds to external shampoo products, particularly shampoo soaps that emphasize cleansing, to soften and smooth hair, reduce dryness, and improve hair quality. This cleverly addresses the problem of dry, frizzy hair after shampooing with natural soaps, achieving both cleansing and hair care benefits.

[0032] In the present invention, the weight ratio of the external Chinese medicine liquid to the soap base raw material is preferably 12-18:100, more preferably 14-16:100. In the present invention, the oil raw material preferably includes the following raw materials in parts by weight: 240-260 parts of palm oil, 90-110 parts of coconut oil, and 140-160 parts of castor oil, and more preferably includes the following raw materials in parts by weight: 250 parts of palm oil, 100 parts of coconut oil, and 150 parts of castor oil. The alkali liquid raw material preferably includes the following raw materials in parts by weight: 72-75 parts of sodium hydroxide and 140-160 parts of water, and more preferably includes the following raw materials in parts by weight: 72.5-74.5 parts of sodium hydroxide and 150 parts of water. The alcohol mixture preferably comprises the following raw materials, calculated by weight: 190-200 parts of anhydrous ethanol with a volume fraction of 95% or more and 100-110 parts of glycerol, with the amount of anhydrous ethanol with a volume fraction of 95% or more preferably being 195 parts, and the amount of glycerol preferably being 105 parts. The sugar solution preferably comprises 70-80 parts of sugar and 50 parts of water, more preferably 75 parts of sugar and 50 parts of water.

[0033] The present invention also provides a preparation method of the shampoo soap, comprising the following steps: mixing an alkali solution raw material and an oil raw material, adding an alcohol mixture and a sugar solution, stirring until the mixture reaches a trace state, adding the external Chinese medicine liquid and mixing, then pouring the mixture into a mold, demoulding after solidification, and maturing to obtain the shampoo soap.

[0034] In the preparation method of the shampoo soap of the present invention, the alkali liquor raw materials are preferably first mixed and the water is poured into an alkali-resistant container, such as a stainless steel basin. Glass or plastic containers should be avoided to prevent corrosion or cracking. Then, sodium hydroxide is slowly poured into the water, stirring with a glass rod while pouring until it is completely dissolved (do not pour water into the sodium hydroxide, as it will release a lot of heat and cause splashing). The dissolution process releases a large amount of heat, and the solution temperature can reach 80-100°C. It also produces irritating gases, so the operation needs to be carried out in a well-ventilated area. After dissolution, it is left to cool to 40-50°C (close to the temperature of oil and fat, which is convenient for mixing).

[0035] Then heat and melt the oil raw materials, pour the weighed oil raw materials into another container (such as a stainless steel pot), heat on low heat or melt in water, stir until completely liquid, and control the temperature at 40-50℃ (similar to the temperature of alkali solution to avoid uneven mixing due to excessive temperature difference).

[0036] Slowly pour the cooled lye solution into the oil and fat mixture, stirring rapidly as you pour to ensure thorough mixing. Continue stirring for approximately 15-30 minutes (adjusted depending on the amount of oil and the stirring speed). When the mixture of oil and lye begins to thicken slightly (but not yet reaching the trace stage), add the pre-mixed alcohol mixture (alcohol is volatile, so pour in quickly). Continue stirring for 1-2 minutes until uniform. Then pour in the cooled sugar solution and stir until completely incorporated (the sugar solution may increase the viscosity, so pay attention to the mixture). Continue stirring for approximately 10-15 minutes, until the mixture reaches the trace stage. This is defined as the soap solution leaving a noticeable mark on the surface that doesn't disappear immediately (similar to thick rice paste). Then add the topical Chinese medicine solution and mix, stirring at a constant speed with a glass rod as you pour to ensure thorough mixing. If bubbles appear after mixing, let it sit for 1-2 minutes to allow them to rise. Use a spatula to remove the top layer of solidified soap solution, or spray a small amount of alcohol with a spray bottle to defoam. When the temperature of the mixture drops to 50-55℃, pour it into the mold. When pouring, slowly inject along the edge of the mold. The height should not exceed 10cm to reduce the generation of bubbles. After filling, gently shake the bottom of the mold 2-3 times to expel the bubbles at the bottom. If there are bubbles on the surface, use a toothpick to gently poke or remove the bubbles, and then place the mold on a level table to avoid movement.

[0037] Then slowly pour the soap base and Chinese medicine liquid mixture into the mold, gently shake the mold several times to expel internal bubbles. Seal the mold with plastic wrap (to prevent the alcohol from evaporating too quickly and causing the surface to dry out), place it in a warm place (25-30℃) for about 24 hours, and when it solidifies (the texture is hard and there is no depression when pressed), remove it from the mold and place it in a ventilated, dry, and cool place (avoid direct sunlight). After demolding for 24 hours, the soap base is a light yellow transparent solid, slightly soft, and has moderate hardness after 6 days. Then cut it into blocks and place it to "mature" for 6-8 weeks. During the maturation period, turn the soap block over once a week to ensure that both sides are dried evenly. It can be used when the pH value of the soap base drops to 8-9.

[0038] The technical solutions provided by the present invention are described in detail below with reference to the embodiments, but they should not be construed as limiting the scope of protection of the present invention.

[0080] A shampoo soap capable of promoting hair growth is prepared from the traditional Chinese medicine liquid obtained in Example 3 and a soap base raw material, wherein the weight ratio of the traditional Chinese medicine liquid obtained in Example 3 to the soap base raw material is 16:100; the soap base raw material comprises 500 g of a fat raw material, 223.5 g of an alkali liquor raw material, 300 g of an alcohol mixture, and 125 g of a granulated sugar solution, wherein the fat raw material comprises 250 g of palm oil, 100 g of coconut oil, and 150 g of castor oil, the alkali liquor raw material comprises 73.5 g of sodium hydroxide and 150 g of water, the alcohol mixture comprises 195 g of anhydrous ethanol and 105 g of glycerin, and the granulated sugar solution comprises 75 g of granulated sugar and 50 g of water.

[0081] The preparation method is:

[0082] (1) Dissolving alkali solution raw materials:

[0083] Pour water into a stainless steel basin, then slowly pour sodium hydroxide into the water, stirring with a glass rod at 15 revolutions per minute until it is completely dissolved to obtain the alkali solution raw material, and place it to cool to 45°C.

[0084] (2) Heating and melting the oil raw materials:

[0085] Pour the weighed oil into another stainless steel pot, heat over low heat to melt, stir until completely liquid, and control the temperature at 45°C.

[0086] (3) Mixing alkali liquor raw materials and oil raw materials (saponification reaction begins):

[0087] Slowly pour the lye solution into the oil, stirring rapidly at 15 revolutions per minute to ensure thorough mixing. Continue stirring for 20 minutes.

[0088] (4) Then add the pre-mixed alcohol mixture (mix anhydrous ethanol and glycerin in advance) and continue stirring for 2 minutes until uniform. Then pour in the sugar solution and stir until completely blended. Continue stirring until the mixture reaches the Trace state, then add the external use Chinese medicine solution obtained in Example 3 and mix, stirring at a constant speed with a glass rod while pouring to ensure that the two are fully mixed.

[0089] (5) Slowly pour the alcohol into the mold and gently shake it to remove any bubbles. Seal the mold with plastic wrap (to prevent the alcohol from evaporating too quickly and causing the surface to dry out), and place it in a warm place (25-30°C) for 24 hours.

[0090] (6) Demolding and maturation:

[0091] After the heat preservation is completed, observe whether it is solidified (the texture is hard and there is no dent when pressed). If it is solidified, remove it from the mold, cut into blocks, and place it in a ventilated, dry, and cool place (avoid direct sunlight) to "mature" for 7 weeks (longer than ordinary soap base maturation because it contains alcohol and sugar, which requires full evaporation of water and neutralization of alkalinity). During the maturation period, turn the soap block over once a week to ensure that both sides are evenly dried. The final pH value of the soap base drops to 8-9 before use.
