Description

Technical Field

[0001] The present invention belongs to daily chemical products, and particularly relates to a preparation method of a guava and hydroxyprolisane essence. Background Art

[0002] With the improvement of the public's awareness of beauty and the continuous change of people's living conditions, skin care products have become necessities in people's lives. Among them, essence is an important step for people to condition the skin and improve the skin barrier. At present, there are many types of essence on the market, but it is not common to have an essence that can both shrink pores, whiten, moisturize, and have antioxidant effects to form a protective barrier for the skin, and the cost is also high.

[0003] Guava contains a large amount of nutrients, various mineral components and trace elements useful to the body, and its nutritional components have very high value in beauty and skin care. It can effectively moisturize the skin, enhance skin vitality, and inhibit and dissolve melanin produced by sun exposure, keeping the skin away from pigmentation and maintaining health and brightness.

[0004] Hydroxyprolisane was originally derived from a plant in Europe. This plant contains rich xylose. Hydroxyprolisane is an extracted glycoprotein mixture that can promote the secretion of glycosaminoglycans. The network structure of glycosaminoglycans can prevent skin moisture loss, thereby maintaining skin elasticity and firmness. Thus, it is a very good anti-aging method.

[0005] Hydroxyprolisane is an ether and also a non-ionic surfactant with strong dispersion and emulsification capabilities. It can help other active ingredients enter the skin and then be absorbed by the skin. At the same time, it also has a certain effect on moisturizing the skin, enhancing elasticity and improving wrinkles. Hydroxyprolisane can promote the accelerated production of type IV and type VII collagen in dermal cells, strengthen the dermal-epidermal connection, fill glycosaminoglycans in the network of type IV collagen, improve skin relaxation caused by aging, and thus reduce wrinkles.

[0006] Improving enlarged pores: Bird's nest has an efficient moisturizing effect. For various enlarged pores, there is mainly a certain relationship with skin moisture content. Many enlarged pores are caused by long-term imbalance between water and oil. The addition of our bird's nest can well improve the skin's water shortage problem, open the skin pores, better absorb the active ingredients in the essence, improve the skin cutin layer, and thus well solve the skin water replenishment problem.

[0007] Anti-aging: Oxygen free radicals are the main factors leading to skin aging problems. Excessive oxygen free radicals will damage skin cells and the skin barrier. Staying up late will also exacerbate skin aging. Our active ingredients, guava and hydroxyproline, both have good antioxidant activities. Especially now, people advocate natural and pollution-free products. The main components in the water extract of guava are phenols and flavonoids, which are natural antioxidants. They can not only effectively inhibit the generation of free radicals but also scavenge free radicals, thus improving the skin barrier. Hydroxyproline stimulates the skin to produce proteoglycans, making the skin elastic. Hydroxyproline can also thicken and repair the cutin layer, making the skin less sensitive.

[0008] Whitening: In contemporary society, many people consider fairness as beauty. However, due to ultraviolet radiation, unavoidable radiation from various electronic products, and irregular daily routines, the facial color and luster have decreased. Whitening essence mainly refers to the addition of one or more active ingredients, which can accelerate the metabolism of melanin or inhibit the formation of melanin. Currently, many essences contain antioxidant vitamin derivatives, niacinamide, arbutin, and other ingredients. With the improvement of people's living standards, the requirements for essence are also getting higher and higher. Now, it is not only limited to various synthetic substances but also requires the essence to be green, safe, and allergen-free. Therefore, there are many essences on the market. The guava and hydroxyproline we extracted are relatively safe ingredients, and their ability to scavenge oxygen free radicals is comparable to that of VC. Especially, hydroxyproline can stimulate the production of glycosaminoglycans to maintain skin vitality. VC mainly reduces the formation of melanin by inhibiting the activity of tyrosinase and slowing down the conversion of tyrosine. However, it is easily oxidized to dihydroascorbic acid and inactivated in the air. Niacinamide is extremely unstable and easily damaged by acids and bases. Moreover, for sensitive skin, a certain tolerance needs to be established. Arbutin is mainly obtained from bearberry leaves and is widely welcomed because of its low price. Summary of the Invention

[0056] Example 3 Antioxidant Experiment

[0057] 1. Experimental method

[0058] 1.1 Determination of ABTS radical scavenging rate:

[0059] The antioxidant reacts with 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) diammonium salt to change the color of the system. Prepare guava extract solution and hydroxyprolisone solution with different concentrations. Take 7 mmol·L -1 of ABTS solution and 1.4 mmol·L -1 of K 2 S 2 O 8 solution, mix them evenly in equal volumes, place them in a dark environment for 24 h, dilute the mixed liquid with distilled water to make its absorbance 0.7 ± 0.02, and you can get the working solution. Add 150 μL of the working solution and 50 μL of the sample solution to a 96-well plate, react for 6 min in a dark environment, measure the absorbance value with an enzyme-linked immunosorbent assay (ELISA) reader, set the wavelength to 734 nm, and record it as A sample; in the blank group, replace the sample solution with deionized water; in the control group, replace the working solution with deionized water, use VC as a positive control, and measure the absorbance values at different concentrations. Conduct the above experiments more than three times, calculate the average value, and the same below. Calculate the scavenging rate: (A− is the absorbance value of the sample, A 0 − is the absorbance value of the control group, A 1 − is the absorbance value of the blank group)

[0060] By comparing with ascorbic acid, it can be found that the ability of the active substances in the essence to scavenge ABTS radicals is basically the same as that of ascorbic acid.

[0061] 1.2 Determination of the scavenging ability of hydroxyl radicals

[0062] Prepare a solution of FeSO 4 and salicylic acid with a certain concentration. 2 mmol / L of H 2 O 2。Use a pipette to aspirate 200 μL of guava extracts and hydroxyprolisilane dissolution solutions with different concentration gradients into a centrifuge tube. Then add 200 μL of 2 mmol·L - 1 FeSO 4 solution and 200 μL of 2 mmol·L -1 H 2 O 2 solution to the centrifuge tube, and let it react at room temperature for 10 min. Add 200 μL of 2 mmol·L -1 salicylic acid solution to the centrifuge tube, shake well to mix evenly, and place it in a 37°C water bath for 30 minutes. In the blank group, distilled water is used to replace the essence active substance, and in the control group, distilled water is used to replace the salicylic acid solution. The wavelength of the microplate reader is 510 nm, and the absorbance value is measured. Using VC as the positive control, calculate the scavenging rate of each group.

[0063] The scavenging rate is (A− is the absorbance value of the sample, A 0 − is the absorbance value of the control group, A 1 − is the absorbance value of the blank group)

[0064] 1.3 Determination of total reducing power

[0065] The total antioxidant capacity of the sample was determined by the iron reducing ability method. 0.2 mol·L -1 Phosphate buffer solution. 1% potassium ferricyanide. 10% trichloroacetic acid, 0.1% ferric chloride solution. Add 500 μL of 0.2 mol·L -1 phosphate buffer solution (pH = 6.6), 200 μL of essence base liquid active substance solution, and 500 μL of 1% potassium ferricyanide to a 2 mL centrifuge tube, mix well and place it in a water bath at 50°C for 20 min. Add 500 μl of 10% concentration trichloroacetic acid, let it stand for 10 min, and it needs to be mixed evenly. Take out 500 μL of the fractionation liquid, add 500 μL of H 2 O, 100 μL of 0.1% ferric chloride solution, let it stand for 10 min, set the wavelength of the microplate reader to 700 nm, measure the absorbance, and indicate the strength of the reducing power. Calculate the scavenging rate.

[0066] The scavenging rate is (A− is the absorbance value of the sample, A 0 − is the absorbance value of the control group, A 1 − is the absorbance value of the blank group)

[0067] 1.4 Determination of DPPH free radical scavenging ability:

[0068] In the 2,2-diphenyl-1-picrylhydrazyl (DPPH) experiment, the antioxidant scavenges DPPH to form non-radical DPPH, and the reaction system changes from purple to yellow. Different concentrations of aqueous solutions of active substances in the essence base solution are mixed with DPPH ethanol solution (1:3), placed in the dark at room temperature for 30 minutes, and the absorbance is measured at 517 nm, denoted as A. Ethanol was used instead of DPPH to measure the absorbance, denoted as A 0 , and the sample solvent was used instead of the sample, and the absorbance was measured in the same way, denoted as A 1 , and ascorbic acid was used as a positive control and measured in the same way to calculate the scavenging rate.

[0069] The scavenging rate is (A− is the absorbance value of the sample, A 0 − is the absorbance value of the control group, A 1 − is the absorbance value of the blank group)

[0070] Usage method: After cleansing the face, use a hot towel to apply a wet compress to open the pores, take a certain amount of essence, and import it with a heated essence instrument. After ten minutes, cleanse the face with clean water.

[0071] The beneficial effects of the present invention are specifically illustrated through the following experiments:
