Description

Technical Field

[0001] This invention relates to the field of cosmetic technology, and in particular to a color cosmetic product with acne-removing function. Background Technology

[0002] Currently, most makeup products on the market focus on immediate coverage and beautification. However, for problem skin (especially acne-prone skin), using traditional makeup products often carries the risk of clogged pores, irritating acne, and worsening inflammation. Although some products claim to contain acne-fighting ingredients, they often have the following limitations: Active ingredients (such as salicylic acid, benzoyl peroxide, etc.) are highly irritating and are not suitable for sensitive skin or long-term use; Natural plant extracts (such as tea tree oil) added directly have poor stability in the formula, are easily deactivated, and have a strong odor or poor compatibility with the makeup base; The product has a single efficacy and lacks synergistic treatment of the causes of acne (oil peroxidation, bacterial infection, and inflammatory response); The product's aroma comes from directly added fragrances, which are highly volatile and have a short lasting effect, failing to provide a long-lasting pleasant experience.

[0003] Green tea extract, rich in tea polyphenols and catechins, possesses excellent antioxidant, anti-inflammatory, and antibacterial properties against Propionibacterium acnes. Viola yedoensis, a traditional medicinal plant, has extracts proven to have broad-spectrum antibacterial and anti-inflammatory effects. However, a key technical challenge lies in how to stably and efficiently integrate these two water-soluble or highly polar natural active ingredients into oil- and powder-based cosmetic matrices, achieving slow release to prolong their effect. Furthermore, innovative solutions are needed to ensure products possess a long-lasting, soothing fragrance that does not interfere with the function of the active ingredients. Summary of the Invention

[0004] The technical problem this invention aims to solve is to overcome the shortcomings of existing technologies and provide a color cosmetic product with acne-removing functions. This product utilizes an innovative carrier system to effectively encapsulate and protect green tea extract and violet extract, allowing them to remain stably within the makeup system and be slowly released after use, achieving long-lasting and gentle acne-removing and anti-inflammatory care. Simultaneously, microencapsulation technology enables a sustained release of fragrance, enhancing the product's user experience.

[0005] To achieve the above objectives, this application provides the following technical solution: a color cosmetic with acne-removing function, comprising a color cosmetic matrix, an acne-removing active complex, and a sustained-release fragrance system; the acne-removing active complex is composed of green tea extract and violet extract, and is loaded in a porous adsorption carrier; the sustained-release fragrance system is formed by encapsulating plant essential oil fragrances with cyclodextrin.

[0006] Preferably, the mass ratio of the green tea extract to the violet extract is 1:1 to 3:1.

[0007] Preferably, the porous adsorption carrier is a mesoporous silica microsphere with a pore size of 2-50 nm and a specific surface area greater than 250 m² / g.

[0008] Preferably, the cyclodextrin is β-cyclodextrin, hydroxypropyl-β-cyclodextrin, or methyl-β-cyclodextrin; the plant essential oil fragrance is selected from at least one of tea tree essential oil, lavender essential oil, frankincense essential oil, and citrus essential oil.

[0009] Preferably, by weight percentage, it comprises: 75-90% makeup base, 2-8% acne-fighting active complex, 1-5% sustained-release fragrance system, and the remainder being cosmetically acceptable excipients.

[0010] Preferably, the makeup product is BB cream, CC cream, liquid foundation, concealer, loose powder, or pressed powder.

[0011] A method for preparing a color cosmetic with acne-removing function, comprising the following steps: (1) Green tea extract and Viola yedoensis extract were loaded onto a porous adsorption carrier to obtain acne-removing active complex microspheres; (2) The plant essential oil fragrance was encapsulated with cyclodextrin to obtain sustained-release fragrance microcapsules; (3) Mix the products obtained in steps (1) and (2) with the makeup base and excipients, and homogenize them to obtain the final product.

[0012] In summary, the technical effects and advantages of this invention are as follows: Synergistic Efficacy and Targeted Care: This innovative formula scientifically combines green tea and Viola yedoensis extract to synergistically treat acne through multiple pathways, including anti-oxidation (reducing lipid peroxidation), anti-inflammation (reducing redness and swelling), and antibacterial properties (inhibiting Propionibacterium acnes), resulting in a more comprehensive and gentler treatment.

[0013] Breakthroughs in stability and long-lasting effects: By loading mesoporous silica microspheres, the problems of difficult dispersion and easy inactivation of natural extracts in oil-based cosmetic matrices have been solved. The nanopores of the microspheres enable controlled sustained release of active ingredients, prolonging the duration of action and improving bioavailability.

[0014] Sensory experience innovation: Utilizing cyclodextrin inclusion technology, volatile essential oil fragrances are transformed into stable solid powders. The fragrance release changes from the traditional "burst" to a "soothing and long-lasting" release. It is slowly released through friction during makeup application and skin temperature, bringing a pleasant fragrance experience all day long, while avoiding the irritation that may be caused by direct contact of fragrance with the skin.

[0015] Product positioning differentiation: This invention successfully integrates therapeutic care functions into daily makeup, creating a truly "functional makeup" that meets the core demand of acne-prone skin consumers who want both beauty and health, giving it a significant competitive advantage in the market.
