Abstract
Description
Technical Field
[0001] This invention belongs to the field of cosmetic technology, specifically relating to a composite facial mask with sanguisorba officinalis polyphenols and aloe vera juice as the main active ingredients, its preparation method, and the application of the facial mask in moisturizing and anti-oxidation. Background Technology
[0002] With the upgrading of health consumption concepts, skincare products are transforming from basic functional products to safe, natural, and highly effective ones. Plant-based cosmetics are receiving increasing attention due to their wide availability, high activity, and low irritation. Face masks, with their high essence-carrying capacity, occlusive absorption-enhancing effects, and convenient experience, are experiencing continuous market growth.
[0003] Sanguisorba officinalis, a perennial herb of the Rosaceae family, possesses cooling, hemostatic, detoxifying, and astringent properties. It is rich in polyphenols, flavonoids, and triterpenoid saponins, among other active ingredients. Polyphenols, in particular, exhibit outstanding antioxidant capabilities, scavenging free radicals and inhibiting lipid peroxidation, showing significant potential in delaying skin aging. Aloe vera gel contains polysaccharides, amino acids, and other active substances, possessing moisturizing, film-forming, and repairing functions, enhancing the skin barrier and reducing moisture loss. Scientifically combining the antioxidant properties of Sanguisorba officinalis polyphenols with the moisturizing and repairing functions of aloe vera holds promise for developing composite skincare products with dual benefits.
[0004] However, current natural plant-based face masks generally suffer from problems such as unscientific processing, unclear content of active ingredients, and poor stability. For the *Sanguisorba officinalis*-aloe vera composite system, the polyphenol extraction process has not been systematically optimized, the compounding ratio lacks scientific basis, and the evaluation system for the physicochemical properties and performance of the finished product is incomplete. Although there are relevant research methods for plant polyphenols available for reference, a systematic report on the full-process development and evaluation of this composite face mask has yet to be seen. Summary of the Invention
[0005] The purpose of this invention is to address the problems of insufficient optimization of natural plant mask formulas, unclear content of active ingredients, and poor product quality stability in the existing technology, and to provide a reasonable formula, stable performance, and excellent moisturizing and antioxidant functions of a Sanguisorba officinalis polyphenol-aloe vera composite mask and its preparation method.
[0006] This invention first provides a method for preparing a Sanguisorba officinalis polyphenol-aloe vera composite facial mask, comprising the following steps: (1) Extraction and purification of Sanguisorba officinalis polyphenols: Sanguisorba officinalis raw material was mixed with 50% ethanol aqueous solution and extracted at 52℃ for 40-45 min. After solid-liquid separation, concentration and drying, crude extract of Sanguisorba officinalis polyphenols was obtained. After dissolving in water, it was purified by precipitation with 95% alcohol and then purified by adsorption with AB-8 macroporous resin. The purification conditions were: sample concentration 1 mg / mL, sample volume 320 mL, sample flow rate 2 mL / min, eluent concentration 70% ethanol aqueous solution, eluent volume 130 mL, and elution flow rate 2 mL / min, to obtain polyphenol extract with a purity of 48%.
[0007] (2) Extraction of aloe vera juice: Wash, peel and cut fresh aloe vera into pieces, put them into a blender and crush them to obtain fresh aloe vera juice for later use (the whole process is done in the dark to prevent the oxidation of active ingredients). (3) Preparation of composite mask: Mix 1.4-3.0 parts of the Sanguisorba officinalis polyphenol extract obtained in step (1) with 20-40 parts of the aloe vera juice obtained in step (2), add 1.4-2.2 parts of sodium carboxymethyl cellulose, 13 parts of glycerin, 1.0 parts of Panax notoginseng powder, 2.0 parts of pearl powder and 1 part of sweet orange essential oil, stir evenly to obtain the Sanguisorba officinalis polyphenol-aloe vera composite mask.
[0008] This invention further provides a *Sanguisorba officinalis* polyphenol-aloe vera composite facial mask prepared by the above method. The mask is a uniform light brown color, with a delicate texture and no roughness, and has a pure, light orange scent. The mask has a pH of 7.0, which is within the safe range of 4.0–8.5, close to the physiological pH of the skin, and has low irritation. The drying time of the mask is 1050–1200 s, similar to commercially available masks, and the effect is good. The mask shows no stratification, color change, or particle precipitation after being stored for 24 hours under normal temperature (25℃), high temperature (40℃), and low temperature (-10℃) conditions, demonstrating good stability. The mask has a stretch diameter of 50–70 mm, good stretchability, and can evenly cover the skin surface.
[0009] The present invention also provides the application of the above-mentioned Sanguisorba officinalis polyphenol-aloe vera composite mask in the preparation of skin care products with moisturizing and / or antioxidant functions.
[0010] 1. Application in the preparation of skincare products with antioxidant functions. The mask's excellent antioxidant activity was confirmed through DPPH and hydroxyl radical scavenging experiments.
[0011] 2. Application in the preparation of moisturizing skincare products. Moisturizing performance tests confirmed that the mask maintained a moisturizing rate of 0.52–0.64 within 5 hours, demonstrating excellent moisturizing properties. Attached Figure Description

Detailed Implementation
[0020] Example 1: Extraction and content determination of Sanguisorba officinalis polyphenols (1) Extraction of Sanguisorba officinalis polyphenols: Weigh 24 g of Sanguisorba officinalis powder, pour 600 mL of 50% ethanol solution (liquid-to-solid ratio 25:1) into a beaker containing the Sanguisorba officinalis powder, stir well, and seal. Place the beaker in a constant temperature water bath preheated to 52℃ and heat for 40-45 min. Filter the extract to remove the fine residue of Sanguisorba officinalis, and obtain a dark brown mixture. Concentrate and dry to obtain crude extract of Sanguisorba officinalis polyphenols (135.92 ± 0.14 μg / g).
[0021] (2) Purification of Sanguisorba officinalis polyphenols: AB-8 macroporous resin was pretreated and purified using macroporous resin. 320 mL of crude extract with a concentration of 1 mg / mL was added to the above chromatography column at a rate of 2 mL / min. The column was first washed with distilled water to remove impurities, and then eluted with 130 mL of 70% ethanol aqueous solution at a flow rate of 2 mL / min. Finally, the eluent was concentrated and lyophilized to obtain purified Sanguisorba officinalis polyphenols (purity of about 48%).
[0022] (3) Determination of the content of Sanguisorba officinalis polyphenols: The content of Sanguisorba officinalis polyphenols was determined by the Folin-Ciocalteu method. A standard curve was plotted using gallic acid as a standard, and the absorbance was measured at a wavelength of 760 nm. The regression equation was y = 0.3767x - 0.00703, R² = 0.99669, showing excellent linearity. Sanguisorba officinalis sample solutions of 0.1 mg / mL and 0.25 mg / mL were prepared, and the absorbance was measured using the same method. The polyphenol content was calculated, and the purity of the purified Sanguisorba officinalis polyphenols was approximately 48%.
[0023] Example 2: Extraction of Aloe Vera Juice Wash the fresh aloe vera, peel and cut it into pieces, put it into a blender and crush it to obtain fresh aloe vera juice, set aside (keep the process away from light to prevent oxidation of the active ingredients).
[0024] Example 3: Mask Formula Optimization Basic formula (per serving): 1.4-3.0 g of Sanguisorba officinalis polyphenols, 20-40 g of aloe vera extract, 1.4-2.2 g of sodium carboxymethyl cellulose, 1.0 g of Panax notoginseng powder, 2.0 g of pearl powder, 10 mL of glycerin, and 1 mL of essential oil.
[0025] The effect of each factor on the moisturizing rate of the face mask was investigated by using a single-factor variable method, controlling the dosage of Sanguisorba officinalis polyphenols, aloe vera extract, and sodium carboxymethyl cellulose as variables, while keeping other components constant.
[0026] Example 4: Effect of Sanguisorba officinalis polyphenol dosage on the moisturizing rate of face masks Following the method of Example 3, with other components fixed, the effect of different amounts of Sanguisorba officinalis polyphenols (1.4 g, 1.8 g, 2.2 g, 2.6 g, 3.0 g) on the moisturizing rate of the face mask was investigated. The results are as follows: Figure 1 As shown in the figure. The results showed that the overall moisturizing rate of 2.2 g of Sanguisorba officinalis polyphenols was higher than that of other dosages within 0.5 h to 5 h, especially the moisturizing rate of 0.8313 after 2 h, which was significantly better than that of 1.4 g (0.6503) and 1.8 g (0.7172). Finally, 2.2 g was selected as the optimal dosage.
[0027] Example 5: The effect of aloe vera juice dosage on the moisturizing rate of face masks Following the method of Example 3, with other components fixed, the effect of different amounts of aloe vera extract (20 g, 25 g, 30 g, 35 g, 40 g) on the moisturizing rate of the face mask was investigated. The results are as follows: Figure 2 As shown in the figure. The results indicate that 35 g of aloe vera extract has the best moisturizing effect within 0.5 h to 5 h, and its moisturizing performance is similar to that of 40 g, but it saves more raw materials. Therefore, 35 g is determined to be the optimal amount of aloe vera extract.
[0028] Example 6: Effect of sodium carboxymethyl cellulose dosage on the moisturizing rate of face mask Following the method of Example 3, with other components fixed, the effect of different amounts of sodium carboxymethyl cellulose (1.4 g, 1.6 g, 1.8 g, 2.0 g, 2.2 g) on the moisturizing rate of the face mask was investigated. The results are as follows: Figure 3 As shown in the figure. The results indicate that 2.0 g of sodium carboxymethyl cellulose had the best overall moisturizing rate within 0.5 h to 5 h, and could ensure that the mask texture was delicate and easy to apply, thus determining 2.0 g as the optimal dosage.
[0029] Based on the optimization results of Examples 4-6, the optimal formula was finally determined to be: 2.2 g of Sanguisorba officinalis polyphenols, 35 g of aloe vera liquid, 2 g of sodium carboxymethyl cellulose, 1 g of Panax notoginseng powder, 2 g of pearl powder, 10 mL of glycerin, and 1 mL of essential oil.
[0030] Example 7: Determination of Physicochemical Properties of Facial Mask (1) Appearance: The mask prepared according to the optimal formula is a uniform light brown color with no color difference; the texture is delicate and without roughness; the fragrance is pure light orange, without bitter taste or odor; there are no contaminants or bubbles, which meets the appearance requirements of skin care products.
[0031] (2) pH determination: The pH of the mask was determined according to the dilution method in GB / T 13531.1-2008. 9 g of deionized water and 1 g of mask sample (diluted to water at a ratio of 1:9) were added to two beakers respectively. The mixture was heated to 40℃ and stirred until homogeneous. After cooling to room temperature, the pH was measured, and the experiment was repeated twice. The pH values of both parallel experiments were 7.0, which is within the safe range of 4.0–8.5, close to the physiological pH of the skin, and has low irritation.
[0032] (3) Drying time: Apply an appropriate amount of mask evenly to a glass plate (5.0×5.0 cm), place at room temperature, and record the drying time as long as it is no longer sticky to the touch. The drying time is 1050-1200 s, which is close to that of commercially available masks (literature data 1166 s, 1104 s), indicating good results.
[0033] (4) Stability test: 4 g of the mask was weighed and placed in a 20×120 mm glass test tube, sealed with a stopper, and stored under normal temperature (25℃ / 24 h), high temperature (40℃ / 24 h), and low temperature (-10℃ / 24 h) conditions. The results showed that there was no stratification, color change, or particle precipitation under the three conditions, indicating good stability.
[0034] (5) Stretchability test: Under conditions of 25℃ and 50% relative humidity, simulated skin was laid flat on two glass plates of the same size. 0.5 g of mask liquid was dropped onto one of the simulated skin plates, and then the other glass plate was placed on top of it in parallel. A weight (5 g) was added above the two glass plates for weight replenishment. After 30 seconds, the diameter of the mask liquid after stretching (longest and shortest diameters) was measured three times consecutively, and the average value was taken. The average stretching diameter was 50-70 mm, indicating good stretchability and the ability to evenly cover the skin surface.
[0035] Example 8: Determination of the antioxidant activity of the facial mask The antioxidant activity of the surface membrane was evaluated using DPPH and hydroxyl radical scavenging assays, and the results are as follows: Figure 6 As shown, within the concentration range of 1-8 mg / mL, the antioxidant activity of the mask is concentration-dependent, with the scavenging rate gradually increasing with increasing concentration, reaching nearly 100% at 8 mg / mL. Similarly, the scavenging rate of the mask against hydroxyl radicals increases with increasing concentration, reaching nearly 70% at 8 mg / mL, indicating that the mask has good antioxidant activity.
