Description

Technical Field

[0001] This application relates to the field of cosmetics, and more specifically, to a natural foundation cream with soothing effects and a method for preparing the same. Background Technology

[0002] In recent years, with consumers' increasing awareness of health and environmental protection, the cosmetics market has shown an increasingly significant trend towards "skincare" and "purification." Consumers are no longer satisfied with cosmetics' mere cosmetic enhancement function, but are instead pursuing products that also offer skincare benefits and contain natural and safe ingredients. As a basic base makeup, foundation cream has a large contact area with the skin and a long contact time; therefore, developing a natural foundation cream with significant soothing and repairing effects has become an urgent market demand.

[0003] Currently, "skin-nourishing" foundations on the market are mainly achieved through two pathways: First, adding one or a few plant extracts (such as aloe vera and licorice) to traditional foundation formulas. However, these active ingredients are often dissolved or dispersed in the matrix, limiting their interaction with the skin and often acting through a single pathway, resulting in incomplete and insignificant soothing effects. Second, using expensive nano-encapsulation technology to deliver active ingredients. While this improves utilization, it is costly and technically complex, and may introduce synthetic carriers, contradicting the "natural" claim. On the other hand, to achieve a lightweight, skin-adhering matte finish, most foundation products rely on silicone oil and its derivatives to construct an oil-phase system. While these ingredients provide a smooth feel, their strong occlusive properties may burden sensitive skin and do not align with consumer preferences for "silicone-free" and "naturally derived" products. Furthermore, traditional pigments are used only as inert pigments in the formula, with a single function, failing to contribute to the skin-nourishing effect. Therefore, how to deeply integrate the concealing and correcting functions of foundation with multi-dimensional and efficient soothing and repairing effects without relying on silicone oil and complex synthesis technology, and develop a truly "makeup and skincare in one" natural product, is a technical problem that urgently needs to be solved in this field. Summary of the Invention

[0004] The purpose of this application is to provide a natural foundation cream with soothing effects and its preparation method.

[0005] In a first aspect, this application provides a natural foundation cream with soothing effects. Based on the total mass of the natural foundation cream, the natural foundation cream with soothing effects comprises: 10-30% modified color powder, 3-15% natural active ingredient system, and 30%-40% silicone-free oil phase; and the balance being an aqueous phase. The modified color powder is obtained by encapsulating the color powder with coconut oil and aloe vera leaf extract. The aloe vera leaf extract is obtained by extracting with coconut oil as a solvent. The natural active ingredient system includes: 2.0%-5.0% β-glucan, 0.25%-1.0% *Phaeodactylum tricornutum* extract; and 1.0%-3.0% a plant complex extract composed of *Coptis chinensis* root extract, *Saussurea costus* root extract, and *Magnolia officinalis* bark extract.

[0006] The above technical solution utilizes a modified pigment encapsulation layer of coconut oil and aloe vera leaf extract. Upon contact with the skin, this releases basic soothing ingredients, transforming the pigment from an inert material into a highly efficient delivery carrier for active soothing components. The compounded β-glucan, *Phaeodactylum tricornutum* extract, and other plant extracts work synergistically against multiple targets, including inhibiting key pro-inflammatory factors (such as TNF-α and IL-6), blocking specific inflammatory pathways (IL-4 / IL-13), and inhibiting inflammatory mediators (NO) and neurosensitive receptors (TRPV1). This effectively and comprehensively reduces skin redness, itching, and discomfort, while repairing the skin barrier. The synergistic effect of active substances and modified pigments ensures that makeup application and coverage are accompanied by the targeted release of soothing ingredients, fundamentally changing the traditional model of separating makeup effects from skincare functions and achieving a simultaneous process of "coverage and repair." The silicone-free oil phase provides excellent spreadability and a refreshing feel, offering an ideal dispersion medium for pigments and active ingredients. Ultimately, this allows the product to achieve a high-coverage, natural-looking finish with a sophisticated matte finish without any silicone oil, while simultaneously meeting the market's demand for pure, natural ingredients. This foundation cream achieves three major functions simultaneously: coverage, soothing, and skin-conditioning. It successfully resolves the contradiction of balancing efficacy, makeup performance, and ingredient purity in natural foundations, providing a truly soothing natural foundation cream.

[0007] In other embodiments of this application, based on the total mass of the natural foundation cream, the soothing natural foundation cream comprises: 16.61% - 20.23% modified color powder, 3.25% - 9.0% natural active ingredient system, and 34% - 39% silicone-free oil phase; and the balance being an aqueous phase.

[0008] In other embodiments of this application, based on the total mass of the natural foundation cream, the natural active ingredient system includes: 4.0%-5.0% β-glucan, 0.6%-1.0% *Phaeodactylum tricornutum* extract; and 2.0%-3.0% a plant complex extract composed of *Coptis chinensis* root extract, *Saussurea costus* root extract, and *Magnolia officinalis* bark extract.

[0009] In other embodiments of this application, the silicone-free oil phase comprises, by weight percentage: 19%-25% grease; 11-18% emulsifier and thickener. Optionally, 5-8% emulsifier; and 6-10% thickener.

[0010] In other embodiments of this application, the oil includes at least one of: coconut oil alcohol-caprylate / decanoate or isostearyl isostearate.

[0011] In other embodiments of this application, the emulsifier includes at least one of polyglycerol-6 polyhydroxystearate, polyglycerol-6 polyricinoleate, polyglycerol-3 diisostearate, or trihydroxystearin.

[0012] In other embodiments of this application, the thickener includes at least one of synthetic beeswax or hydrogenated vegetable oil.

[0013] In other embodiments of this application, the silicone-free oil phase, by weight percentage, comprises: 9-11% cocoyl alcohol-caprylate / capric acid ester; 2-3% trihydroxystearin, 4-6% a complex of polyglycerol-6 polyhydroxystearate and polyglycerol-6 polyricinoleate; 1-2% polyglycerol-3 diisostearate; 8-10% isostearyl alcohol isostearate; 2-3% synthetic beeswax; 2-4% hydrogenated vegetable oil; and 2-4% C9-12 alkylene.

[0014] In other embodiments of this application, the pigment includes at least one of CI 77891, CI 77492, CI 77491 or CI 77499.

[0015] Secondly, this application provides a method for preparing a natural foundation cream with soothing effects, the method comprising: The components in the silicone-free oil phase are heated to dissolve, homogenized and dispersed, and kept at 80-90℃ to obtain an oil phase mixture; The modified color powder is mixed with a solvent and ground until the particle size D90 of the modified color powder is ≤10μm. Then the modified color powder is added to the oil phase mixture to obtain a mixed phase. Mix the components that make up the aqueous phase and heat to 80-90°C. Slowly add the mixed phase while stirring, emulsify, and then cool. Cool to 40-45℃, add to the natural active ingredient system, and stir until homogeneous. Detailed Implementation

[0016] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application will be clearly and completely described below. Obviously, the described embodiments are some embodiments of this application, but not all embodiments.

[0017] Therefore, the following detailed description of the embodiments of this application is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0018] This application provides a soothing natural foundation cream, which, based on the total mass of the natural foundation cream, comprises: 10-30% modified color powder, 3-15% natural active ingredient system, and 30%-40% silicone-free oil phase; and the balance being an aqueous phase; The modified color powder is obtained by encapsulating the color powder with coconut oil and aloe vera leaf extract. The aloe vera leaf extract is obtained by extracting with coconut oil as a solvent. The natural active ingredient system includes: 2.0%-5.0% β-glucan, 0.25%-1.0% *Phaeodactylum tricornutum* extract; and 1.0%-3.0% a plant complex extract composed of *Coptis chinensis* root extract, *Saussurea costus* root extract, and *Magnolia officinalis* bark extract.

[0019] The above technical solution utilizes a modified pigment encapsulation layer of coconut oil and aloe vera leaf extract. Upon contact with the skin, this releases basic soothing ingredients, transforming the pigment from an inert material into a highly efficient delivery carrier for active soothing components. The compounded β-glucan, *Phaeodactylum tricornutum* extract, and other plant extracts work synergistically against multiple targets, including inhibiting key pro-inflammatory factors (such as TNF-α and IL-6), blocking specific inflammatory pathways (IL-4 / IL-13), and inhibiting inflammatory mediators (NO) and neurosensitive receptors (TRPV1). This effectively and comprehensively reduces skin redness, itching, and discomfort, while repairing the skin barrier. The synergistic effect of active substances and modified pigments ensures that makeup application and coverage are accompanied by the targeted release of soothing ingredients, fundamentally changing the traditional model of separating makeup effects from skincare functions and achieving a simultaneous process of "coverage and repair." The silicone-free oil phase provides excellent spreadability and a refreshing feel, offering an ideal dispersion medium for pigments and active ingredients. Ultimately, this allows the product to achieve a high-coverage, natural-looking finish with a sophisticated matte finish without any silicone oil, while simultaneously meeting the market's demand for pure, natural ingredients. This foundation cream achieves three major functions simultaneously: coverage, soothing, and skin-conditioning. It successfully resolves the contradiction of balancing efficacy, makeup performance, and ingredient purity in natural foundations, providing a truly soothing natural foundation cream.

[0020] For example, in some embodiments of this application, the natural foundation cream with soothing effects includes: modified colorant in the range of 10%, 12%, 15%, 18%, 20%, 25%, 30%, or any two of the aforementioned values; a natural active ingredient system in the range of 3%, 4%, 5%, 6%, 8%, 10%, 12%, 13%, 15%, or any two of the aforementioned values; a silicone-free oil phase in the range of 30%, 32%, 35%, 38%, 40%, or any two of the aforementioned values; and the balance being an aqueous phase.

[0021] For example, in some embodiments of this application, the natural active ingredient system includes: β-glucan at a content of 2.0%, 2.2%, 2.5%, 2.8%, 3.0%, 3.2%, 3.5%, 3.8%, 4.0%, 4.2%, 4.5%, 4.8%, 5.0%, or any two of the aforementioned values; *Phaeodactylum tricornutum* extract at a content of 0.25%, 0.26%, 0.28%, 0.30%, 0.35%, 0.36%, 0.38%, 0.40%, 0.45%, 0.50%, 0.55%, 0.60%, 0.65%, 0.70%, 0.75%, 0.80%, 0.90%, 1.0%, or any two of the aforementioned values; and a plant complex extract composed of *Coptis chinensis* root extract, *Saussurea costus* root extract, and *Magnolia officinalis* bark extract at a content of 1.0%, 1.2%, 1.5%, 2.0%, 2.5%, 3.0%, or any two of the aforementioned values.

[0022] Optionally, in some embodiments of this application, the modified pigment is obtained by extracting aloe vera leaves from coconut oil to obtain an active, lipophilic aloe vera extract, which is then encapsulated with a composite of coconut oil and aloe vera leaf extract. For example, the modified pigment contains pigment, coconut (COCOS NUCIFERA) oil, and Aloe barbadensis. Coconut oil soothes the skin, improves moisture, and provides excellent spreadability. Aloe barbadensis leaf extract reduces irritation and soothes the skin. Aloe barbadensis contains anthraquinone compounds, such as aloin, which can reduce local redness, swelling, heat, and pain by inhibiting the release of inflammatory mediators (such as prostaglandins and leukotrienes). This surface-treated pigment has excellent hydrophobic properties, is easy to disperse, and provides a dry, lightweight skin feel.

[0023] Further optionally, in some embodiments of this application, the aforementioned β-glucan is selected from Xishiyin® SPG β-glucan (β-glucan, 1,2-pentanediol, water), which can be purchased from Best Pharmaceutical (Guangzhou) Co., Ltd., and synthesized by fermentation; further optionally, in some embodiments of this application, the aforementioned *Phaeodactylum tricornutum* extract is selected from Optimmunist (water, 1,3-propanediol, *Phaeodactylum tricornutum* extract, lecithin), which can be purchased from ALGAKTIV SL, and extracted with alcohol; further optionally, in some embodiments of this application, the aforementioned plant complex extract is selected from *Magnolia officinalis* (water, 1,3-propanediol, *Coptis chinensis* root extract, *Vladimiria souliei* root extract, *Magnolia officinalis* bark extract), which has a skin-soothing effect. For example, it is purchased from Senxin Fragrance & Pigment Technology (China) Co., Ltd.

[0024] In some embodiments of this application, Xishiyin® SPGβ-glucan is a bioactive polysaccharide prepared by using edible and medicinal fungi as fermentation strains. It can inhibit the production of pro-inflammatory factors TNF-α and IL-6, reduce skin α value, reduce skin redness, soothe skin discomfort, protect the skin barrier, and reduce transepidermal water loss. The aforementioned Optimmunist is a dual inhibitor that locally targets IL-4 and IL-13 to block the inflammatory cascade. It soothes and calms the skin by downregulating the expression of key pro-inflammatory interleukins IL-1β and IL-8, while reducing itching, rash, and redness by downregulating IL-2 secretion, thus protecting and repairing the skin barrier and resisting various external stimuli. The aforementioned Magnolia officinalis can significantly inhibit the release of inflammatory factors NO and IL-6 (NO can be secreted by macrophages and directly kill pathogenic microorganisms; high concentrations of NO can activate neutrophil chemotaxis. Interleukin-6 (IL-6) stimulates macrophage function, enhances phagocytic activity, and releases pro-inflammatory factors), thus having an anti-inflammatory effect. At the same time, it can significantly reduce TRPV1 (TRPV1 (transient receptor potential vanillic acid subtype 1) is a non-selective cation channel protein belonging to the TRP ion channel family, distributed in sensory nerve endings, keratinocytes, etc., and involved in various physiological and pathological processes such as pain and inflammation), improving discomfort such as skin itching and inflammation. The three work together to act on different stages of the inflammatory cascade, covering multiple dimensions of soothing such as skin redness, itching, and barrier damage through multi-pathway synergy, forming complementary enhancements and synergistic effects.

[0067] The results above show that the effects of Examples 1-3 are significantly higher than those of Comparative Examples 1-6, indicating that the solutions of this application have a clear synergistic effect and improve the soothing effect.

[0068] Compared to Comparative Example 7, which uses a silicone oil-containing formula, Example 1 can achieve a soothing effect comparable to a silicone oil system. However, Comparative Example 7, with its silicone oil-containing formula, has strong occlusive properties and a longer makeup-wearing time, which can easily aggravate sensitive skin and does not conform to consumer preferences for "silicone-free" and "naturally sourced" products.

[0069] This demonstrates that the solution described in this application can be well used in silicone-free systems, is environmentally friendly, and has excellent soothing effects. Therefore, this application's solution can be used in silicone-free systems, making it environmentally friendly. II. Covering Effect The procedure was performed on volunteer skin, concealing artificial markers: pores and acne scars. Evaluation was conducted using a visual method.

[0070] Two identical circular marks were drawn on clean, dry skin on the inside of the volunteer's forearm using a standard pigment pen. A photograph of the unpainted area was taken under standard lighting conditions. A fixed amount of sample was taken from each example and evenly applied to cover one of the marks. The other mark served as a control. Immediately after application, a photograph was taken under the same lighting conditions. The coverage effect was blind-scored by at least three trained evaluators using a blemish coverage scale. Scores ranged from 0 to 10, where 0 = no coverage and 10 = complete coverage.

[0071] The test results are as follows: Table 10

[0072] The results above show that: Experimental Examples 1-3 have excellent concealing properties, effectively covering pores and acne scars.

[0073] Comparative Example 1 uses regular pigments, which have poor coverage and cannot cover some pores and acne scars. Comparative Example 3 uses no pigments and has almost no coverage.

[0074] Compared to Comparative Example 7, Example 1, which uses a silicone oil-containing formula, offers comparable coverage to silicone oil-based systems. However, Comparative Example 7, with its silicone oil-containing formula, exhibits strong occlusive properties and longer makeup-wearing time, potentially burdening sensitive skin and not aligning with consumer preferences for "silicone-free" and "naturally derived" products. In contrast, the solutions described in this application demonstrate that the solutions can be effectively used in silicone-free systems, are environmentally friendly, and offer excellent coverage.

[0075] III. Skin Feel Adjustment The assessment is conducted by at least five professionally trained sensory evaluators.

[0076] Steps and rating scale: Immediate application stage: The evaluator takes the standard amount and applies it to simulated skin using standardized techniques. 15-30 minutes after application, the evaluator assesses whether the skin feels suffocated, on a scale of 0-10; if it feels thick and has a film-like feel, the score is 1 point; if it feels light and imperceptible, the score is 10 points.

[0077] The test results are as follows: Table 11

[0078] The results above show that: Experimental Examples 1-3 exhibit skin-feeling adjustment properties that are lightweight and adhere to the skin.

[0079] Comparative Example 1 uses ordinary pigments, which have poor spreadability, only provide some assistance, are not light and skin-friendly enough, and have poor skin feel adjustment performance.

[0080] Compared to Comparative Example 7, Example 1 uses a silicone oil-containing formula, while Comparative Example 7 uses a silicone oil-containing formula. Silicone oil evaporates quickly, and as makeup wear time increases, residual oils and emulsions can cause changes in makeup effect due to silicone oil loss. The hydrophobic nature of silicone oil hinders sweat evaporation, creating a stuffy feeling in hot environments and easily aggravating sensitive skin. Furthermore, common silicone oils, such as cyclosiloxanes, are listed as Substances of Very High Concern (SVHCs) by the European Union due to their persistence, bioaccumulation, and potential toxicity. Studies have shown that these substances can persist in the environment for extended periods and accumulate in organisms, posing a threat to ecosystems and human health. In particular, D4 (octamethylcyclotetrasiloxane) has been proven to be highly toxic to aquatic organisms and may impair fertility. In addition, cyclosiloxanes have the potential for long-distance environmental transport, meaning they could cause environmental pollution in areas far from their use and production sites, such as the Arctic and Antarctic. Therefore, they do not align with consumer preferences for "silicone-free" and "naturally sourced" products.

[0081] This demonstrates that the solutions described in this application can be well applied to silicone-free systems, are environmentally friendly, and possess excellent skin-feel adjustment properties. Therefore, it is clear that the solutions described in this application can be used in silicone-free systems, making them environmentally friendly. In summary, compared to the comparative examples, the embodiments of this application effectively improve the three major functions of soothing and skin-feel adjustment. Furthermore, the embodiments of this application can be well applied to silicone-free systems, making them environmentally friendly.

[0082] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
