Description

Oil-controlling and moisturizing composition and preparation method thereof

Technical Field

The present invention belongs to the technical field of cosmetic preparation, and in particular, relates to an oil-controlling and moisturizing composition and a preparation method thereof.

Background technique

Excessive secretion of skin oil is usually a manifestation of dry skin, so to control oil, you must first replenish water and moisturize. Dehydrated and dry skin will promote the secretion of oil, leading to an imbalance of water and oil, and it is likely to appear a state of oil outside and dry inside. To reduce oil secretion, it is necessary to replenish skin moisture so as to maintain the water and oil balance of the skin. Therefore, people have always hoped to find a cosmetic that can both control oil and replenish water and regulate the skin with excellent effects. However, although there are many such cosmetics on the market, their performance is still unsatisfactory, and more cosmetics can only better meet people's single needs, such as a single strong water replenishment ability or a single good oil control ability. This is far from enough for people's growing needs and people's increasingly high quality requirements. Therefore, in the preparation of the composition used in cosmetics, it is urgent to develop an oil control and water replenishment composition that combines the two functions of oil control and water replenishment to solve the greasy and dry problems of the skin.

Summary of the invention

The object of the present invention is to provide an oil-controlling and moisturizing composition and a preparation method thereof. The present invention uses red clover stems and leaves, lentil seeds and witch hazel together to inhibit secretion, reduce oil breeding and accumulation, and balance oil secretion, so that the prepared composition has an excellent oil-control effect; the lentil seeds are used to repair the skin stratum corneum, which paves the way for the subsequent moisturizing and hydrating work of dendrobium officinale stems and glycerol polyacrylate. On this basis, the dendrobium officinale stems play an excellent moisturizing role, and the glycerol polyacrylate enhances the moisturizing effect; at the same time, the present invention also adds clove oil to reduce the damage of free radicals to cells, protects cells from the influence of oxidative stress, and makes the prepared composition have an antioxidant effect; and solves the problem of lack of oil-control and moisturizing performance in the existing cosmetic composition technology.

The purpose of the present invention can be achieved through the following technical solutions:

Beneficial effects of the present invention:

(1) The present invention adds red clover stems and leaves rich in isoflavone compounds such as flavonols, flavonoids, and isoflavones to inhibit aminopeptidase N (APN) in human sebaceous glands, thereby affecting the differentiation process and basic metabolic reactions of cells, and further inhibiting excessive secretion of sebum; adds lentil seeds, which contain isoflavone compounds that are active ingredients for regulating sebaceous gland activity, and reduce sebum secretion, thereby reducing the growth and accumulation of oil on the skin surface; in addition, witch hazel containing multiple ingredients such as quercetin, witch hazel tannin, quercetin, tannic acid, witch hazel sugar gallate and astragaloside is added, and the lentil seeds and red clover stems and leaves penetrate into the skin to assist the lentil seeds and red clover stems and leaves in balancing the oil secretion of the skin, comprehensively regulating the skin and consolidating the oil control effect; that is, the red clover stems and leaves, lentil seeds and witch hazel work together to inhibit secretion, reduce the growth and accumulation of oil, and balance oil secretion, so that the prepared composition has an excellent oil control effect.

(2) The stratum corneum is a barrier between the internal and external environments, which helps to properly retain skin moisture and prevent foreign matter from invading. Therefore, the stratum corneum is essential for maintaining the moisture content on the skin surface. A healthy stratum corneum is more conducive to hydrating and locking in moisture for the skin. During the research and development process, the experimenters unexpectedly discovered that the lentil seeds also have the function of strengthening the supporting structure of the pore wall and promoting the recovery of the normal keratinization process of keratinocytes. That is, the lentil seeds added in the present invention can better repair the stratum corneum of the skin, paving the way for the subsequent hydrating and moisturizing work of the Dendrobium officinale stems and glycerol polyacrylate, so as to absorb more moisture and effectively lock in moisture.

(3) The present invention adds Dendrobium officinale stems rich in active nutrients such as polysaccharides, flavonoids, phenols, amino acids, vitamin C, etc. The large amount of hydroxyl groups contained in its structure will combine with water in the form of hydrogen bonds, and on the premise that the lentil seeds promote the normal keratinization of keratinocytes, it plays an excellent role in replenishing water; and glycerol polyacrylates can effectively combine water molecules with the cage structure formed by glycerol polyacrylates through van der Waals forces and hydrogen bonds. When the finished product containing glycerol polyacrylates contacts the skin, the friction or changes in skin temperature will cause the cage structure to be slowly destroyed, thereby releasing water to moisturize the skin, which further enhances the moisturizing effect. Under this raw material composition, the oil-controlling and moisturizing composition prepared by the present invention exhibits an excellent moisturizing and water-locking effect.

(4) The present invention adds white clove oil and Dendrobium officinale stems, so that the prepared composition also has an excellent antioxidant effect. This is because the rich antioxidant substances eugenol, eugenol aldehyde, etc. in the clove oil added by the present invention react with free radicals, thereby reducing the damage of free radicals to cells and protecting cells from oxidative stress. On this basis, together with the rich polysaccharides, flavonoids, and phenolic substances contained in the Dendrobium officinale stems, they effectively remove excess free radicals in the human body and maintain the balance of free radicals in the body, so that the prepared composition has an antioxidant effect.

As can be seen from Table 3, the oil-controlling and moisturizing composition prepared by the present invention has an excellent moisturizing and water-locking effect. The present invention uses lentil seeds to repair the skin stratum corneum, paving the way for the subsequent moisturizing and hydrating work of Dendrobium officinale stems and glycerol polyacrylate, in order to absorb more water and effectively lock the water. On this basis, the Dendrobium officinale stems play an excellent moisturizing role, and glycerol polyacrylate combines water molecules to the cage structure formed by glycerol polyacrylate through van der Waals forces and hydrogen bonds, which enhances the moisturizing effect. Under this raw material composition, the oil-controlling and moisturizing composition prepared by the present invention exhibits an excellent moisturizing and water-locking effect.

Test Example 3

(1) Test samples: The oil-controlling and moisturizing compositions prepared in Examples 1-3, Comparative Example 4 and Comparative Example 7 were prepared into sample solutions with water. The concentration of the sample solutions was 6%.

(2) Test item: Antioxidant test

Take 0.1mL of sample solution, add 2mL of 60μmol/L DPPH solution, mix well, let stand for 30min, adjust the zero point with the original solvent, and measure the absorbance at 517nm as Ai; in the same way, mix 0.1mL of anhydrous ethanol solvent + 2mL of DPPH solution and measure the absorbance as Ac; mix 0.1mL of sample solution + 2mL of anhydrous ethanol solvent and measure the absorbance as Aj. Calculate the free radical scavenging rate according to the following formula:

Clearance (%) = [1-(Ai-Aj)/Ac] × 100%;

Among them, Aj is the contribution of the reaction sample itself to the absorbance; Ai is the absorbance value of the sample after the action of DPPH; Ac is the absorption of DPPH itself at the measurement wavelength;

The results are shown in Table 4.

As can be seen from Table 4, the oil-controlling and moisturizing composition prepared by the present invention has excellent antioxidant effect. This is because the rich antioxidant substances eugenol, eugenol aldehyde, etc. in the clove oil added by the present invention react with free radicals, thereby reducing the damage of free radicals to cells and protecting cells from oxidative stress. On this basis, together with the rich polysaccharides, flavonoids, and phenolic substances contained in the stems of Dendrobium officinale, they effectively remove excess free radicals in the human body and maintain the balance of free radicals in the body, so that the prepared composition has antioxidant effect.
