Description

Technical Field

[0001] This invention belongs to the field of cosmetic technology, specifically relating to a composition with oil-controlling and cleansing effects and its application. Background Technology

[0002] As the largest epidermal barrier in the human body, the health of the skin depends on the dynamic stability of its water-oil balance. The sebum secreted by the sebaceous glands and the water in the stratum corneum together form the skin's hydrolipidic film, which not only locks in internal moisture and resists the invasion of external pollutants, but also prevents problems such as clogged pores, dullness, and acne caused by excessive sebum secretion. With the improvement of living standards, the popularization of skincare concepts, and the influence of environmental factors, skin problems such as oiliness, inadequate cleansing, and dry, tight skin have become core concerns for most consumers worldwide. The proportion of people with oily and combination skin continues to rise, highlighting the growing demand for integrated oil control, cleansing, and moisturizing skincare, driving oil-controlling, cleansing, and moisturizing cosmetics to become one of the core categories in the skincare market.

[0003] CN115919715A discloses a mild, low-viscosity, high-foaming cleaning composition and its preparation method. The cleaning composition comprises potassium cocoyl glycinate, potassium cocoate, sodium lauroyl collagen amino acid, disodium cocoamphodiacetate, lauroylpropyl hydroxysulfonyl betaine, soybean seed extract, hydrogenated lecithin, polyquaternium-51, citric acid, and a matrix. This cleaning composition is mild and non-irritating, with strong cleaning power; it has a certain consistency, a slightly alkaline pH, and produces rich, dense foam. The present invention also discloses a method for preparing the above-mentioned cleaning composition. This method is simple, convenient, and can effectively produce a mild cleaning composition with a certain viscosity and high transparency.

[0004] CN121337639A discloses a pore-cleansing mud mask and its preparation method, belonging to the field of cosmetic technology. Specifically, it relates to a pore-cleansing mud mask comprising: 14-18 parts kaolin, 7-9 parts Manegugen glacial mud, 4.5-5.5 parts Amazonian white clay, 10-12 parts wheat germ oil, 43-47 parts tea water, 0.1-0.14 parts medicinal styracifolium extract, 1-2 parts *Gynostemma pentaphyllum* powder, 2-4 parts lactobionic acid, 0.08-0.12 parts salicylic acid, and 0.4-0.6 parts gluconolactone. The pore-cleansing mud mask provided by this invention has a uniform particle size distribution, is evenly mixed, and maintains a moist and non-drying state during use. While enhancing oil control, pore unclogging, and anti-inflammatory cleansing power, it does not over-cleanse and cause skin sensitivity. It provides a novel cleansing mud mask formula and its efficient and stable preparation method for achieving the goal of "pore cleansing."

[0005] Currently, various cosmetics claiming to have oil-control, cleansing, and moisturizing effects have appeared on the market. However, some products have problems such as insufficient cleansing power and short-lived oil-control effects, making it difficult to meet the deep cleansing needs of people with oily skin. In addition, there are also obvious deficiencies in terms of formula synergy, technological advancement, long-lasting efficacy, and skin type compatibility. Therefore, there is an urgent need to develop a product that can achieve a synergistic balance of cleansing power, oil control, and moisturizing, while also being gentle, long-lasting, and safe to meet the application needs. Summary of the Invention

[0006] In view of the shortcomings of the prior art, the present invention provides a composition with oil-controlling and cleaning effects and its application.

[0007] To achieve this objective, the present invention adopts the following technical solution: In a first aspect, the present invention provides a composition with oil-controlling and cleansing effects, the composition comprising collagen, Himalayan pink salt, walnut shell powder and hydrated silica; The collagen includes any one or a combination of at least two of recombinant human type III collagen, recombinant human type IV collagen, or recombinant human type XVII collagen.

[0008] The walnut shell powder described in this invention is a plant-based natural physical exfoliating particle. Through friction between the particles and the skin surface, it directly removes dead skin cells, sebum plugs in pores, blackheads, whiteheads, and surface-attached oil and dirt, physically unclogging pores and preventing oil buildup and oxidation, thus reducing the visual effects of enlarged pores and excessive oil. The hydrated silica is a porous amorphous silica with a large specific surface area and extremely strong adsorption capacity. It can quickly adsorb excess free oil, sweat, and fatty acids from sebum decomposition on the skin surface, achieving immediate oil control and transforming oily skin into a matte finish. It can also adsorb a small amount of oil from pore openings, reducing oil seepage to the skin surface. The Himalayan pink salt removes surface oil and dirt through friction, while the crystalline surfaces of the particles can gently scrape away superficial sebum plugs in pores, further unclogging them. The collagen can address the issue of "oil rebound caused by over-cleansing." The product not only addresses the issue of oily skin, but also replenishes the skin's stratum corneum with moisturizing factors, repairs the damaged stratum corneum barrier, and restores the skin barrier to a healthy state. This reduces the need for excessive sebum secretion to protect the skin, thereby indirectly controlling oil production. The combination of these four ingredients in oil-controlling cleansing has a synergistic effect, which can better absorb excess oil on the skin's surface, regulate skin texture, remove dead skin cells, unclog pores, and remove surface oil and dirt from pores.
