Description

Technical Field

[0001] The present invention relates to the field of cosmetics, in particular to a composition with oil-controlling and repairing effects, a preparation method and application thereof. Background Art

[0002] Skin is the largest protective barrier of the human body. The keratin in the stratum corneum, intercellular matrix and polysaccharides in its epidermis together constitute a line of defense against external stimuli. However, factors such as environmental pollution, bad eating habits, mental stress, light from the sun and electronic products, aging, hormone changes, drug abuse and diseases may damage this barrier, leading to skin sensitivity, burning, stinging, itching, dermatitis, erythema, acne, scaling, aging and dryness. Therefore, cosmetics with soothing and repairing effects are increasingly popular among consumers. However, the soothing and repairing ingredients in these products mostly rely on hormone drugs, which may cause skin intolerance or drug resistance, and aggravate skin problems. In addition, excessive sebum secretion will enlarge pores, lead to water loss, further stimulate the sebaceous glands to secrete more oil, form a vicious cycle, and ultimately damage the skin barrier. Therefore, when screening oil-control raw materials, the need to repair the skin barrier must be considered simultaneously.

[0003] Patent CN118267323A discloses an oil control and repair composition, the raw materials for its preparation include, by mass content: dipeptide-15 3-4.5wt%, oligopeptide-1 0.1-0.2wt%, dianthin 0.002-0.01wt%, Tibetan mushroom extract 0.005-0.015wt%, PEG-40 hydrogenated castor oil 1-2wt%, hexanediol 0.2-1wt%, pentanediol 1-5wt%, cellulose 0.1-0.5wt%, pH regulator for adjusting the pH of the composition system to 4-7, and the balance is water. The composition has long-term stability, is used in skin care products, has oil control, soothing, repair effects, and is safe and non-toxic; however, there are many types of raw materials, the preparation process is relatively complicated, and the production cost is relatively high, which is not conducive to large-scale promotion and use.

[0004] Therefore, there is an urgent need for a cosmetic composition that can not only control oil and repair skin but also has simple component types and low additive content. Summary of the invention

[0005] In order to solve the above technical problems, the first aspect of the present invention provides a composition with oil control and repairing effects, comprising: plant extracts, functional substances and water; the plant extracts include: Norway spruce leaf extract (Piceaexcelsa), Lotus corniculatus root extract (Lotus corniculatus), Calendula officinalis extract (Calendulaofficinalis), myrtle extract (Rhodomyrtus tomentosa), and Polygonum cuspidatum root extract (Polygonumcuspidatum).

[0006] As an implementable example, the average inhibition rate of the composition with oil-controlling and repairing effects on α-reductase is greater than 50%.

[0007] As an implementable case, the mass ratio of the plant extract and the effective substance is (1-30): (0.1-3).

[0008] As an implementable case, the mass ratio of the plant extract, the effective substance and water is (1-30): (0.1-3): (60-100).

[0009] As an implementable case, the mass ratio of the Norway spruce leaf extract, the lotus root extract, the calendula extract, the myrtle extract, and the knotweed root extract is (1-15): (0.1-2): (0.5-5): (0.1-2): (0.5-5).

[0010] As an implementable case, the effective substances include: one or more of nicotinamide, glycyrrhizin, tranexamic acid acetyl glucosamine, diglucosyl gallic acid, salicylic acid, ectoine and ergothioneine.

[0011] Furthermore, the effective substance includes niacinamide.

[0012] Furthermore, the purity of the nicotinamide is greater than 99%.

[0013] Furthermore, the niacin content in the niacinamide is less than 70 ppm.

[0014] The plant extracts in the present invention include Norway spruce leaf extract, Lotus japonicus root extract, calendula officinalis extract, myrtle extract and knotweed root extract, and the effective substance includes niacinamide. Norway spruce leaf extract is derived from the Aurora black spruce in Canada at 60° north latitude. The extract can effectively decompose sebum and resist bacteria, making oily skin refreshing and soft, and effectively removing dirt from pores. At the same time, Lotus japonicus seed extract contains flavonoids, alkaloids and other ingredients, which can accurately regulate sebaceous glands, reduce sebum secretion, and achieve the effect of oil control and shrinking pores. In addition, the product also includes niacinamide with a purity of more than 99%, which can reduce the production of fatty acids and triglycerides in the sebum secreted by the skin; calendula extract has a significant anti-inflammatory effect, and its rich active ingredients such as flavonoids and saponins can effectively reduce the inflammatory response of the skin, relieve discomfort symptoms such as redness, itching and pain, and is natural, safe and effective; myrtle extract from Fujian, China, is rich in a variety of beneficial ingredients, which can inhibit the release of inflammatory mediators and the expression of cytokines, thereby exerting an anti-inflammatory effect; it can relieve inflammatory symptoms such as swelling and pain by regulating immune responses and reducing tissue damage. The root extract of Polygonum cuspidatum, which has been extracted and concentrated at high temperature, also has the characteristics of natural safety and efficient oil control. These ingredients work together on the skin, with excellent oil control and repair effects. The raw materials are non-toxic, highly safe and have excellent stability, which can meet the needs of various skin types.

[0015] The second aspect of the present invention provides a method for preparing a composition with oil-controlling and repairing effects, comprising: mixing the raw materials of various components and stirring them evenly to obtain the composition.

[0016] The third aspect of the present invention provides an application of a composition having oil-controlling and repairing effects in cosmetics.

[0017] As an implementable case, the dosage form of the cosmetic includes one of cream, lotion, essence, gel, and lotion.

[0018] Beneficial Effects

[0019] (i) The oil control component provided by the present invention can effectively inhibit sebum secretion and achieve a significant oil control effect. Moreover, as the total content of plant extracts and functional substances increases, the inhibition rate of 5α-reductase is significantly improved, and the oil control effect is more excellent.

[0020] (ii) The plant extracts described in the present invention include: Norway spruce leaf extract, Lotus japonicus root extract, Calendula officinalis extract, Myrtle extract, Polygonum cuspidatum root extract; the effective substance includes niacinamide. When a certain component is missing from the raw material components, the inhibition rate of 5α-reductase is greatly reduced, indicating that the raw material components in the present invention have a coordinated and enhanced effect; the components work together on the skin to exert a better oil control effect.

[0021] (III) After replacing a certain component in the present invention with a common oil-control ingredient on the market, such as the extract of Hamamelis Virginiana, the inhibition rate of 5α-reductase was significantly reduced, indicating that the oil-control component provided by the present invention is carefully screened and has a unique oil-control effect, and other oil-control components cannot be conventionally selected or replaced.

[0022] (IV) The plant extracts and functional substances in the present invention are natural and have been extracted or concentrated at high temperature to ensure the natural safety of the product. At the same time, after a human skin closed patch test, the results showed that there was no positive reaction among 30 people, proving that the composition will not cause adverse reactions to the skin of the subjects and has high safety and stability.

[0023] (V) The oil control and repair composition of the present invention not only has excellent oil control effect, but also can repair the skin, make oily skin refreshing and tender, and effectively remove dirt from pores. At the same time, since all components are natural and harmless, after a specific raw material ratio, it can meet the needs of various skin types and provide comprehensive care for the skin.
