Embodiment 1

[0022] The preparation of embodiment 1 agar oligosaccharide extract:

[0023] Heat and dissolve 100g of agar in Tris-HCl buffer solution of pH 8.5. After the agar solution is cooled, mix the agar and agarase in a ratio of 3:1, that is, add 33g of agarase to make the agar solution The final concentration is 0.3%, cultured at 45°C and 200r / min for 12h, boiled for 5min, the agar-oligosaccharide extract mixture was cooled overnight at 4°C, and the unreacted agar and polysaccharide were precipitated to the bottom Centrifuge at 8000r / min for 10min, take 500mL of supernatant, concentrate the supernatant by rotary evaporation, and dialyze with a dialysis bag with a molecular cutoff of 200Da to remove small molecule salts. Dilute the dialyzed agar oligosaccharide extract mixture to the concentration before dialysis, add 0.25% activated carbon, absorb at room temperature for 1 hour, then suction filter, add the activated carbon obtained by suction filtration to a concentration of 65% et...

Embodiment 2

[0024] The preparation of sticky sodium alginate in embodiment 2:

[0025] Weigh an appropriate amount of 200g kelp, wash, dry, crush, add 600mL ethanol for reflux extraction, add 1000mL hot water for reflux extraction to the residue for 2 hours, filter, concentrate the filtrate, add 1200mL ethanol, place overnight, filter, and the obtained precipitate is dried as medium viscosity Seaweed polysaccharides.

Embodiment 3

[0026] The preparation of embodiment 3 Astragalus extract:

[0027] Weigh 100g of Astragalus membranaceus, wash, dry, crush, percolate with 1200mL ethanol aqueous solution to obtain percolation liquid and percolation residue, add 150mL ethanol aqueous solution to the percolation residue, soak for 8h, ultrasonic extraction for 60min, obtain ultrasonic Extraction and ultrasonic extraction residue, the ultrasonic extraction and percolation liquid are combined, filtered, and the filtrate is evaporated under reduced pressure and concentrated to 15% of the original volume to obtain the Radix Astragali extract.

Abstract

The invention discloses an antioxidant, soothing and moisturizing cream composition and a preparation method thereof. The antioxidant, soothing and moisturizing cream composition comprises an antioxidant active component and a conventional cosmetic component as raw materials, wherein the antioxidant active component comprises an agar oligosaccharide extract, medium-viscosity sodium alginate and anastragalus membranaceus extract. Through selection of a specific natural trehalose substance and a Chinese herbal extract for compounding as well as selection of a specific dosage ratio, a specific preparation technology and specific parameters, the antioxidant, soothing and moisturizing cream composition with high stability is obtained, and a synergistic effect is achieved in the aspect of antioxidant efficacy.

Description

technical field [0001] The invention belongs to the technical field of daily cosmetics, and in particular relates to an antioxidant soothing moisturizing cream composition and a preparation method thereof. Background technique [0002] China has a vast sea area and is extremely rich in seaweed resources. The output of kelp and wakame ranks first in the world, and the output of seaweed is second only to Japan. Other seaweeds such as wakame and enteromorpha are also abundant. Seaweed is rich in polysaccharides, polyphenols, terpenes, polyunsaturated fatty acids and other active substances. Seaweed polysaccharides have a variety of biological functions, such as moisture retention, antioxidant activity, antibacterial activity, etc. At present, marine economic algae are widely used in food industry, pharmaceutical industry, energy and other chemical resources at home and abroad. However, my country's current seaweed processing technology is relatively backward, the product is ...
