Description

Technical Field

[0001] This invention relates to the field of skin cream technology, specifically an anti-aging and repairing skin cream based on Panax notoginseng seeds and its preparation method. Background Technology

[0002] Panax notoginseng red seeds are the fruit or seeds of the Panax notoginseng plant (also known as Tianqi). They typically turn bright red after ripening in autumn and have important cultivation and medicinal value. Immature Panax notoginseng red seeds are green, turning bright red or vermilion when ripe. The fruit is kidney-shaped or spherical, containing 1-3 seeds. The ripening period is generally from October to December each year, when the fruit is plump and suitable for harvesting.

[0003] The pulp of Panax notoginseng red seeds is rich in malonyl ginsenosides and polysaccharides, which are highly water-soluble and mild in nature. The kernels, in addition to being rich in classic ginsenosides and flavonoids, also contain a certain amount of oil. If these endogenous oils are not processed, they may cause oxidative stability issues during cell wall breaking and subsequent product storage, affecting the final product's texture. Current technologies typically use a uniform processing method for the whole fruit or different parts of Panax notoginseng red seeds, neglecting the challenges and opportunities presented by the characteristics of the kernel oils. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and propose an anti-aging and repairing skin cream based on Panax notoginseng seeds and its preparation method to solve the above-mentioned problems.

[0005] The objective of this invention is achieved through the following technical solution: An anti-aging and repairing skin cream based on Panax notoginseng red seeds, the skin cream comprising: fresh Panax notoginseng red seed pulp, Panax notoginseng red seed kernel, Bletilla striata, mulberry leaf extract, rose extract, jojoba oil, squalane, glyceryl stearate, sodium hyaluronate, 1,3-propanediol, emulsifier, and deionized water.

[0006] Preferably, the skin cream of the present invention comprises the following components in parts by weight: fresh Panax notoginseng seed pulp: 20-35 parts, Panax notoginseng seed kernel: 15-30 parts, Bletilla striata: 8-15 parts, mulberry leaf extract: 5-12 parts, rose extract: 3-10 parts, jojoba oil: 1-4 parts, squalane: 2-5 parts, glyceryl stearate: 2-4 parts, sodium hyaluronate: 0.1-0.5 parts, 1,3-propanediol: 4-8 parts, emulsifier: 3-4 parts; The ingredients are: glyceryl stearate, sodium hyaluronate, 1,3-propanediol, emulsifier, and deionized water, with a total volume of 100 parts.

[0007] Preferably, the method for preparing the pulp of fresh Panax notoginseng red seeds according to the present invention is as follows: The pulp and kernel of fresh Panax notoginseng red seeds are separated. The pulp is mixed with purified water and then subjected to ultrasonic wet cell wall breaking and sieving to obtain a slurry.

[0008] Preferably, the method for preparing the pulp of the seven-red seed kernels of the present invention is as follows: The separated kernels are stir-fried over low heat at 120-140℃ for 8-12 minutes, cooled, mixed with purified water, and then slurry is obtained by ultrasonic wet cell wall breaking and sieving.

[0009] Preferably, the method for preparing the Bletilla striata slurry according to the present invention is as follows: The sliced ​​Bletilla striata were washed and drained, then mixed with purified water and subjected to ultrasonic wet cell wall breaking and sieving to obtain a slurry.

[0010] Preferably, the ultrasonic wet cell disruption parameters of the present invention are: ultrasonic frequency 28-32kHz, slurry layer thickness 8-12mm, processing time 20-25min, temperature control throughout the process ≤58℃, and cell disruption mill speed 3000±200rpm.

[0011] Preferably, the preparation method of the mulberry leaf extract of the present invention is as follows: The mulberry leaves were extracted by reflux in 70% ethanol, and the extract was concentrated under reduced pressure and then spray-dried to obtain the extract.

[0012] Preferably, the method for preparing the rose extract of the present invention is as follows: Rose petals and water were ultrasonically extracted at 100-200W for 30-60 minutes. The extracted filtrate was concentrated and then freeze-dried to obtain the extract.

[0013] Preferably, the preparation method of the skin cream of the present invention is characterized in that: the preparation method includes the following steps: S1 The pulp of fresh Panax notoginseng red seed pulp, the pulp of Panax notoginseng red seed kernel, and the pulp of Bletilla striata are mixed and filtered to collect the filtrate with a molecular weight ≤50kDa. S2 concentrates the filtrate under a vacuum of -0.085 to -0.092 MPa and a temperature of 45-55℃ to a concentrated slurry with a solid content of 35%-45%; S3 involves mixing and homogenizing jojoba oil, squalane, glyceryl stearate, 1,3-propanediol, sodium hyaluronate, deionized water, mulberry leaf extract, and rose extract at 70-80°C with an emulsifier. After homogenization in step S4, the mixture is cooled to 40-50°C. The concentrated slurry from step S2 is then added and slowly stirred and cooled to room temperature to obtain the product, which is then filled into containers.

[0014] Another object of the present invention is to provide the application of skin cream in anti-aging, skin barrier repair, or whitening and brightening skin care.

[0015] The beneficial effects of this invention are: (1) By roasting the nuts, the present invention can reduce the greasiness of the oil, enhance the warming properties, promote the conversion of some saponins, improve the oxidative stability of the cell wall broken pulp, and generate more skin-care active ingredients. The roasted nuts are then subjected to wet cell wall breaking, which solves the process problems caused by the oiliness, making the final product feel more refreshing and reducing the addition of exogenous oil.

[0016] (2) Through roasting and cell wall breaking process, cell wall breaking refers to cell wall breaking of fresh fruit pulp and cell wall breaking after roasting of kernels. The anti-aging and repairing skin cream prepared in conjunction with Bletilla striata, mulberry leaves and rose flowers effectively regulates the oiliness of kernels and improves the mildness and absorption efficiency of ingredients.

[0017] (3) The amount of jojoba oil used is reduced, which effectively reduces the greasiness of the product and is more suitable for modern consumer preferences, while ensuring sufficient moisturization. Detailed Implementation
