[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0022] A facial mask composition without adding preservatives comprises the following components in parts by weight: 1-1.5 parts of green tea extract, 0.5-1 parts of vitamin E, 1-1.5 parts of melon extract, 1-1.5 parts of artichoke extract, 1-3 parts of niacinamide, 4-6 parts of glycerol and 0.5-1 part of silk protein.

[0023] Green tea extract can block the lipid peroxidation process, increase the activity of enzymes in the human body, stimulate changes in antibody activity by increasing the total amount of human immunoglobulin and maintaining it at a high level, thereby improving the overall immune capacity of the human body;

[0024] Melon extract is rich in vitamin C and other antioxidants, which can help fight free radical damage and slow the aging process of the skin.

[0025] The natural sugars and minerals in melon extract deeply moisturize the skin, leaving it soft and smooth. Melon extract contains certain compounds that have anti-inflammatory properties, which can help reduce skin inflammation and redness. For sensitive or irritated skin types, melon extract can have a soothing effect.

[0026] Artichoke extract has a strong antioxidant effect, and its antioxidant capacity is mainly determined by the number of hydroxyl groups on the aromatic ring. The more hydroxyl groups it contains, the stronger its antioxidant capacity.

[0052] The preparation process of the melon extract is as follows:

[0053] (1) Raw material preparation: Select fresh melon as the raw material. Take the melon pulp, melon seeds and / or the inner layer of the melon (the inner layer with a thickness of 0.5-1.0 cm) as the melon raw material;

[0054] (2) Pretreatment: washing the melon raw material to remove impurities and dirt on the surface;

[0055] (3) crushing and beating: mixing water: melon raw material (m / m) in a ratio of (0.5-2):1, pouring into a colloid mill and homogenizing for 5-10 minutes to obtain melon pulp;

[0056] (4) Filtration under reduced pressure: Pour the melon pulp onto filter paper in a Buchner funnel and filter under reduced pressure to obtain a filtrate;

[0057] (5) Destarchification: placing the filtrate in a centrifuge and centrifuging at a speed of 3000-8000 r / min for 5-20 minutes, and collecting the supernatant as the melon water extract;

[0058] (6) Reflux extraction: add 2-8 times the weight of an organic solvent (such as ethanol, dichloromethane or acetone) to the melon residue obtained by filtration, and then heat and reflux at 50-80° C. for 1-3 hours to obtain an organic solvent extract;

[0059] (7) Molecular distillation:

[0060] First-stage molecular distillation: The organic solvent extract is subjected to first-stage molecular distillation, and the residue is retained. The distillation process parameters are feed temperature 50-60°C, distillation temperature 90-105°C, condensation surface temperature 40-50°C, air residual pressure 0.8-1.5Pa, and feed liquid flow rate 1-5mL / min;

[0061] Secondary molecular distillation: The residue of the primary molecular distillation is subjected to secondary molecular distillation to retain the light phase. The distillation process parameters are feed temperature 50-60°C, distillation temperature 120-130°C, condensation surface temperature 50-65°C, air residual pressure 0.8-1.5Pa, feed liquid flow rate 1-5mL / min;

[0062] (8) Mixing: The melon water extract and the secondary molecular distillation light phase are mixed to obtain the melon extract.

[0063] The artichoke extract uses artichoke leaves or artichokes free of mildew, spots, diseases and insect pests as raw materials.

[0064] The preparation process of artichoke extract is:

[0065] (1) Raw material preparation: drying the selected artichoke leaves or artichokes at a temperature of 35-45° C. for 1-2 hours, then crushing and passing through a 30-50 mesh sieve;

[0066] (2) Extraction: adding ethanol solution at a solid-liquid ratio of 1:35 for ultrasonic extraction, with an ultrasonic power of 100 kW; this step is intended to extract chlorogenic acid; for the filter residue, adding 60% ethanol solution at a solid-liquid ratio of 1:30, reflux temperature of 75-115°C, reflux 3 times, each time for 35 minutes, combining the extracts and concentrating under reduced pressure to obtain cynarin;

[0067] (3) Filtration: Filter the extracted substance through a first filter membrane (usually with a pore size of 0.45 μm) to obtain an extract;

[0068] (4) Concentration: The extract is concentrated to a relative density of 1.08-1.15; during this process, ethanol solutions of different concentrations may be used for alcohol precipitation to improve the purity of the extract;

[0069] (5) Drying: The concentrated extract is spray-dried and sieved to obtain the final artichoke extract.

[0070] The preparation process of green tea extract is:

[0071] Green tea raw materials are added to 8 times the amount of 50-70% ethanol, and extracted three times, and the extraction temperature is controlled at about 70 degrees;

[0072] After the extract is collected, the ethanol is recovered by vacuum evaporation and then centrifuged to collect the supernatant;

[0073] Next, the centrifuged extract was passed through a macroporous resin chromatography column with a diameter-to-height ratio of 1:10, and eluted in batches with 5-15% ethanol until the eluate was clear;

[0074] Afterwards, the eluate is vacuum concentrated until it is free of ethanol smell, and then spray-dried or freeze-dried to finally obtain the green tea extract.
