Description

Technical Field

[0001] This invention relates to the field of daily chemical products technology, specifically to a herbal compound bath and facial cleanser composition that combines whitening, soothing, moisturizing, and hydrating effects. More particularly, it relates to a herbal compound whitening, soothing, moisturizing, and hydrating bath and facial cleanser composition that is readily available, inexpensive, simple to prepare, and gentle and non-irritating. This product is a 20 kg finished product, and all medicinal components are dried medicinal materials. It is suitable for all skin types, including sensitive skin, and can simultaneously meet the multiple needs of human skin for cleansing, whitening, soothing, moisturizing, and hydrating. Background Technology

[0002] With the improvement of people's living standards and the upgrading of skin care concepts, consumers' demand for daily chemical products has shifted from basic cleansing to "skin care + multi-functionality". Among them, bath and facial cleansing products with whitening, soothing, moisturizing and hydrating effects have become market hotspots. According to Euromonitor International data, the Chinese whitening body wash market will exceed 8 billion yuan in 2025, with a compound annual growth rate of 15.3%. "Moisturizing without stickiness" and "gentle and low irritation" have become the core demands of users. 78% of consumers regard "refreshing skin feel" as the primary condition for choosing whitening body wash, 72% of consumers pay attention to "long-lasting moisturizing", and 65% of consumers value "gentle and low irritation". Currently, bath and facial cleansing products on the market are mainly divided into two categories: one is chemically synthesized products, which often contain chemical whitening ingredients such as niacinamide and tranexamic acid. Although they can achieve a certain whitening effect, long-term use can easily irritate the skin, especially making them unsuitable for people with sensitive skin. In addition, some products have problems such as poor moisturizing effect, tight skin, and a slippery feeling after washing. The other category is herbal products, which mostly use single or a few herbal raw materials. Their effects are relatively simple and it is difficult to achieve multiple effects such as whitening, soothing, moisturizing, and hydrating at the same time. Moreover, most herbal products have problems such as high raw material costs, complex preparation processes, and low utilization rate of effective ingredients, making it difficult to meet consumers' core needs of "high cost performance, comprehensive effects, and gentle safety".

[0003] In existing technologies, the formulation design of herbal bath or facial cleansing products often has many shortcomings: First, the combination of herbal raw materials is unreasonable and does not follow the traditional Chinese medicine concept of "principal, assistant, adjuvant and guide" in prescription formulation. As a result, it is difficult for the various components to achieve synergistic effects, leading to single efficacy and limited effects. Secondly, the preparation process is unscientific. Most products use simple soaking or decocting methods without distinguishing the characteristics of herbal raw materials, resulting in the loss of volatile effective ingredients and the destruction of heat-sensitive ingredients, thus reducing the efficacy of the products. Third, improper selection of excipients, such as the addition of highly irritating surfactants and preservatives to some products, affects the mildness of the products; Fourth, poor cost control, the use of scarce herbal raw materials or complex preparation processes, leads to high product prices and makes it difficult to popularize the products.

[0004] For example, most whitening body washes disclosed in the existing technology are based on a single whitening ingredient, such as angelica extract or mulberry bark extract, lacking the synergistic combination of soothing and moisturizing ingredients. Although they can achieve a certain whitening effect after use, they are prone to causing problems such as dry skin and redness. Some herbal compound products add multiple raw materials, but do not properly distinguish between the components to be decocted first and added later, resulting in the loss of volatile components (such as the active ingredients in rose and chuanxiong) during long-term decoction, reducing the product's soothing and whitening effects. At the same time, the excipient systems of existing products mostly use a single surfactant, making it difficult to balance cleansing power and gentleness. They are either not cleansing enough or are too irritating, and the preservative systems of some products have safety hazards, which may cause potential damage to the skin with long-term use.

[0005] Furthermore, most existing herbal daily chemical products are designed for a single function, either for bathing or facial cleansing only. Consumers need to purchase two products simultaneously, which is inconvenient and increases costs. Therefore, developing a herbal compound composition that uses readily available and inexpensive raw materials, has a simple preparation process, and combines whitening, soothing, moisturizing, and hydrating effects while being gentle and non-irritating, and can be used for both bathing and facial cleansing, has become a pressing technical problem for the daily chemical industry.

[0006] Based on the shortcomings of existing technologies and combined with the TCM concept of "principal, assistant, adjuvant, and guide" in formulating prescriptions, this invention selects 12 common and readily available herbal raw materials, rationally divides them into a pre-decocted group and a post-added group, and combines them with a mild and efficient excipient system. The preparation process is optimized and strict quality control standards are set to develop a "most cost-effective" herbal compound whitening, soothing, moisturizing, and hydrating bath and facial cleanser composition. This not only solves the problems of existing products having single efficacy, skin irritation, high cost, and complex preparation, but also achieves five-in-one effects of "cleansing + whitening + soothing + moisturizing + hydrating," while also catering to both bathing and facial cleansing uses, meeting the diverse needs of consumers and possessing broad market application prospects. Summary of the Invention

[0007] The purpose of this invention is to overcome the shortcomings of existing herbal bath and facial cleansing products, such as limited efficacy, poor gentleness, high cost, unreasonable preparation process, low utilization rate of effective ingredients, and inability to simultaneously serve as both bath and facial cleansing products. This invention provides a herbal compound whitening, soothing, moisturizing, and hydrating bath and facial cleansing composition. This composition uses 12 common and readily available herbal raw materials, with a scientific formulation, simple preparation process, and low cost. It combines multiple effects of whitening, soothing, moisturizing, hydrating, and cleansing, is gentle and non-irritating, suitable for all skin types, especially sensitive skin, and can be used for both bathing and facial cleansing. This solves the problems of inconvenience and high cost for consumers. Furthermore, strict process control ensures stable product quality and reliable efficacy.

[0015] A method for preparing a herbal compound whitening, soothing, moisturizing, and hydrating bath and facial cleanser composition includes the following steps: (1) Clean the decoction group separately and drain it for later use: Select the herbs for the decoction group, remove impurities and moldy parts, clean them separately with clean water, and drain them until there is no obvious dripping water. (2) Soak the first decoction group for 3 hours, with the water surface covering the herbs: Put the drained herbs of the first decoction group into the decoction container, add water, and soak for 3 hours until the water surface completely covers the herbs. (3) Boil over high heat, then simmer over low heat for 1 hour: Heat the soaked herbs and soaking liquid, bring to a boil over high heat, then reduce to low heat and simmer for 1 hour. (4) Clean the last batch of herbs 10 minutes before putting them into the pot. Wash them gently without rubbing or soaking, and put them into the pot immediately: Select the herbs for the last batch and wash them gently with clean water 10 minutes before putting them into the pot. Do not rub or soak them. After washing, put them into the decoction container immediately. (5) After the last batch of herbs are added, bring to a boil over high heat, then simmer over low heat for 5 minutes and turn off the heat. (6) Steep for 1 hour, seal and do not open the lid: After turning off the heat, seal the cooking container, do not open the lid or stir, and steep for 1 hour; (7) Hot grading and filtration: First, use a 200-300 mesh filter for coarse filtration, and second, use a 400-500 mesh filter for fine filtration. Cool and set aside: After steeping, perform grading filtration while hot, with a filtration temperature not lower than 80℃, to obtain the herbal extract. Let it cool naturally to room temperature. (8) Mixing excipients: Mix the cooled herbal extract with the excipient components in proportion and stir evenly. During the mixing process, first add the surfactant, thickening system, preservative system, moisturizing and repairing components and optional additives to the herbal extract in sequence. After each excipient is added, stir until completely dissolved before adding the next one to ensure even mixing and avoid phenomena such as layering and precipitation. The herbal compound whitening, soothing, moisturizing and hydrating bath and facial cleansing composition is obtained.

[0016] Furthermore, the following mandatory red lines must be strictly followed during the preparation process: The first-cooking group and the second-added group must not be washed or placed together; the second-added group must be washed 10 minutes before being added to the pot, and should not be washed or soaked in advance; after the second-added group is added, bring it to a boil again over high heat and then simmer over low heat for 5 minutes; simmer for 1 hour, keeping the pot sealed, without opening the lid or stirring; filtering must be done while hot and graded: the first filtration should be 200-300 mesh, and the second filtration should be 400-500 mesh, to ensure that it is clear, without residue or suspended matter.

[0017] Furthermore, the composition has a pH value of 4.5-6.5, making it suitable for dry, oily, combination, and sensitive skin. It can be used as both a shower gel and a facial cleanser, offering cleansing, whitening, soothing, moisturizing, and hydrating benefits.

[0018] Compared with the prior art, the present invention has the following significant advantages: 1. Comprehensive Efficacy and Strong Synergistic Effect: This invention selects 12 herbal ingredients, strictly adhering to the traditional Chinese medicine concept of "principal, assistant, adjuvant, and guide" in its formulation. Sapindus mukorossi is the principal ingredient, mulberry bark and coix seed are the assistant ingredients, angelica dahurica, aloe vera peel, winter melon peel, sophora flavescens, and dandelion are the adjuvant ingredients, and licorice and saposhnikovia divaricata are the guiding ingredients. Each component works synergistically, combined with an optimized and gentle excipient system, truly achieving a five-in-one effect of "cleansing + whitening + soothing + moisturizing + hydrating," completely solving the problem of single-effect products in existing products. Specifically, angelica dahurica, mulberry bark, coix seed, and winter melon peel synergistically inhibit melanin production and brighten skin tone; sophora flavescens, dandelion, licorice, and saposhnikovia divaricata synergistically soothe and reduce inflammation, relieving skin redness and itching, making it especially suitable for sensitive skin; aloe vera peel, coix seed, panthenol, and squalane synergistically moisturize and hydrate, replenishing skin moisture, repairing the skin barrier, and improving dry and rough skin.

[0019] 2. Mild and non-irritating, with high safety: The medicinal components of this invention are all natural herbal raw materials, free of artificial whitening agents, hormones, heavy metals, and other harmful ingredients. The excipients are selected from industry-recognized mild and non-irritating raw materials. The surfactant uses a golden compound system of alkyl glycoside 1214 + cocoaminopropyl betaine (CAB) + sodium cocoyl glutamate + low content of fatty alcohol polyoxyethylene ether sulfate. Among them, cocoaminopropyl betaine can significantly reduce the irritation of other surfactants while improving the fineness of foam. The mildness of the entire surfactant system is far superior to that of a single formula, and it is almost non-irritating to the skin and eyes. The preservative uses a compound system of phenoxyethanol, ethylhexylglycerin, pentylene glycol, and potassium sorbate, which is mild, safe, and leaves no residue. The product's pH value is strictly controlled within the weakly acidic range of 4.5-6.5, which is completely in line with the physiological environment of human skin. It is suitable for dry skin, oily skin, combination skin, and sensitive skin. Pregnant women, infants, and other special groups can also use it with confidence. Long-term use will not cause any harm to the skin.

[0020] 3. Low cost and high cost-effectiveness: The 12 herbal ingredients selected for this invention are all common and readily available varieties in the market, with wide sources and low prices, and no rare or precious medicinal materials. The excipients are also all low-cost, high-performance daily chemical-grade raw materials, and the preparation process is simple, requiring only conventional decoction pots, stirrers, and filters, without the need for complex extraction and purification equipment. This significantly reduces the product's production cost, achieving the design goal of the "most cost-effective version." Simultaneously, the product has dual uses for bathing and facial cleansing, eliminating the need for consumers to purchase two separate products, further reducing usage costs. This allows ordinary consumers to obtain comprehensive and high-quality skincare effects at an extremely low price, facilitating large-scale promotion and application.

[0021] 4. Scientific preparation process with high utilization rate of active ingredients: Based on the physicochemical properties of different herbal raw materials, this invention scientifically divides them into a pre-decocting group and a post-decoction group. The pre-decocting group undergoes 3 hours of soaking followed by 1 hour of simmering over low heat to ensure the full dissolution of water-soluble active ingredients. The post-decoction group is strictly controlled by washing 10 minutes before adding to the pot and decocting for only 5 minutes to maximize the retention of volatile active ingredients in rose and chuanxiong. Simultaneously, a 1-hour sealed soaking step utilizes residual heat to further promote the dissolution of active ingredients and prevent the loss of volatile components. The graded filtration process (200-300 mesh coarse filtration + 400-500 mesh fine filtration) not only thoroughly removes medicinal residues of different particle sizes but also avoids the retention and loss of active ingredients caused by residue clogging during traditional single-layer or double-layer filtration. Compared with traditional herbal daily chemical product preparation processes, the process of this invention can increase the overall utilization rate of herbal active ingredients by more than 35%, significantly superior to existing technologies.

[0022] 5. Dual-purpose and convenient to use: The composition of this invention has been optimized in formula and adjusted in process, achieving a perfect balance between cleaning power and gentleness. It can be used for both body bathing and facial cleansing. Consumers do not need to buy two products at the same time, which saves on consumption costs and is convenient to carry and use. It is especially suitable for business trips, travel and other scenarios, meeting the diversified and convenient lifestyle needs of modern consumers.

[0023] 6. Stable quality and long shelf life: This invention employs a scientific quaternary preservative compound system, which effectively inhibits the growth of various microorganisms such as bacteria, mold, and yeast. Hydrogenated castor oil CO40, as a highly efficient solubilizer, can completely solubilize oil-soluble components such as fragrances and essential oils, fundamentally solving the common problems of fragrance layering and turbidity in herbal products. The graded filtration process thoroughly removes all solid residues and fine suspended matter from the product, preventing residues from acting as carriers for microbial growth and causing product spoilage. Simultaneously, strict process control ensures stable quality between batches, preventing discoloration, off-flavors, layering, sedimentation, and other phenomena. The product has a shelf life of over 18 months at room temperature, facilitating storage, transportation, and sales.

[0024] 7. Excellent user experience: The optimized surfactant compound system produces rich and delicate foam that rinses off thoroughly without residue or slippery residue; the product is clear and transparent after graded filtration, free of any impurities and suspended matter, and feels smooth on the skin when applied; the natural herbal fragrance is perfectly blended with the added mild fragrance, resulting in a fresh and natural scent without any pungent odor; after use, the skin feels refreshed and moisturized without any tightness, and long-term use can significantly improve skin problems such as dullness, dryness, and roughness, enhancing the overall condition of the skin.

[0025] 8. Environmentally friendly and safe, green and healthy: The herbal raw materials of this invention are all natural and renewable resources, and the auxiliary components are mostly biodegradable ingredients with no harmful residues, which is environmentally friendly. No harmful chemicals need to be added during the preparation process, and there is no wastewater, waste gas, or waste residue discharge. The production process is green and environmentally friendly, which is in line with the current industry development trend of "green skin care and sustainable development". Detailed Implementation

Choose mild and non-irritating fragrances / essential oils to avoid skin irritation.

[0034] (III) Preparation process The preparation process of this invention is simple, requires no complex equipment, and is low in cost. Furthermore, through strict process steps and mandatory red lines, it ensures the full dissolution of the effective components of the medicinal materials, resulting in stable product quality. The specific steps are as follows: The first decoction group is cleaned and drained separately: Select the 10 herbs in the first decoction group, remove impurities and moldy parts, and then wash them separately with clean water to avoid mixing with the herbs in the subsequent decoction group. After washing, drain the water until there is no obvious dripping water. This step can remove dust and impurities from the surface of the herbs and avoid affecting the purity of the product. Soak the pre-decoction group for 3 hours, with the water surface covering the herbs: Place the drained pre-decoction group herbs into a decoction container, add water, and the water surface must completely cover the herbs. Soak for 3 hours to allow the herbs to fully absorb water, which facilitates the rapid and full dissolution of the effective ingredients during subsequent decoction. Avoid stirring the herbs during the soaking process to prevent premature loss of effective ingredients. Bring to a boil over high heat, then simmer over low heat for 1 hour: Heat the soaked herbs and soaking liquid together. First, bring to a boil over high heat, then reduce to low heat and simmer for 1 hour. Bringing to a boil over high heat quickly reaches the decoction temperature, while simmering over low heat avoids high temperature from damaging the heat-sensitive active ingredients in the herbs, and at the same time ensures that the active ingredients are fully dissolved. Wash the last batch of ingredients 10 minutes before putting them into the pot. Wash gently without rubbing or soaking, and put them into the pot immediately: Select the rose petals and chuanxiong in the last batch of ingredients, remove impurities, and wash them gently with clean water 10 minutes before putting them into the pot. Avoid rubbing or soaking during washing to prevent the loss of volatile effective ingredients. After washing, put them into the decoction container immediately to avoid prolonged storage that could cause the effective ingredients to evaporate. After adding the last batch of herbs, bring to a boil over high heat, then simmer over low heat for 5 minutes. Turn off the heat. Steep for 1 hour, sealed and do not open the lid: After turning off the heat, keep the decoction container sealed, do not open the lid or stir, and steep for 1 hour. Use the residual heat in the container to further promote the dissolution of the effective ingredients of the medicinal materials, while preventing the loss of volatile effective ingredients and ensuring the utilization rate of effective ingredients. Hot-filtered tiered filtration: First, use a 200-300 mesh filter for coarse filtration, and then use a 400-500 mesh filter for fine filtration. Cool and set aside: After steeping, immediately perform tiered filtration. First, pass the herbs through a 200-300 mesh filter to remove large particles of herbal residue, and then pass the herbs through a 400-500 mesh filter to remove fine suspended matter. The filtration temperature should not be lower than 80℃ to prevent the herbal residue from solidifying and clogging the filter after the temperature drops, and to prevent the active ingredients from precipitating out due to the temperature drop. After filtration, a clear and transparent herbal extract is obtained. Allow the herbal extract to cool naturally to room temperature for use. Mixing excipients: Mix the cooled herbal extract with the excipient components in proportion and stir evenly. During the mixing process, first add the surfactant, thickening system, preservative system, moisturizing and repairing components and optional additives to the herbal extract in sequence. After each excipient is added, stir until completely dissolved before adding the next one to ensure even mixing and avoid phenomena such as layering and precipitation. This will give you the herbal compound whitening, soothing, moisturizing and hydrating bath and facial cleanser composition.

[0035] (iv) Mandatory red line To ensure stable product quality and reliable efficacy, this invention sets the following five mandatory red lines, which must be strictly adhered to during the preparation process; any violations are strictly prohibited: The herbs to be decocted first and those to be added later must not be washed or stored together: The herbs to be decocted first and those to be added later are processed and decocted for different times. Washing or storing them together will cause the volatile active ingredients of the herbs to be added later to be lost prematurely. At the same time, it may also cause the herbs to be decocted first to be contaminated, affecting the efficacy and purity of the product. The ingredients added later must be washed 10 minutes before cooking. Do not wash or soak them in advance: The ingredients added later contain volatile active ingredients. Washing or soaking them in advance will cause a large loss of active ingredients, reducing the soothing and whitening effects of the product. Strictly controlling the washing time and method is the key to ensuring the efficacy of the ingredients added later. After adding the last batch of herbs, bring to a boil again and time for 5 minutes: After adding the last batch of herbs, it is necessary to bring to a boil again over high heat, then reduce to low heat and keep boiling for 5 minutes to ensure that the volatile active ingredients are fully dissolved, while avoiding the loss of active ingredients due to excessive decoction time. Steep for 1 hour, keeping the lid sealed and not stirring throughout the process: During the steeping process, keeping the lid sealed and not stirring can prevent the loss of volatile active ingredients, while using residual heat to promote further dissolution of active ingredients. If the lid is opened or stirred in the middle, it will lead to the loss of active ingredients and affect the efficacy of the product. Filtration must be carried out while the product is still hot and graded: the first pass should be 200-300 mesh, and the second pass should be 400-500 mesh, to ensure that the product is clear and free of residue and suspended matter. Hot filtration can prevent the release of effective components and the solidification of residues. Graded filtration can gradually remove medicinal residues of different particle sizes, ensuring that the product is clear and transparent, free of any impurities and suspended matter, improving the quality of the product, and at the same time avoiding residue irritating the skin.
