Embodiment 1

[0031] Embodiment 1: the preparation of spirulina polysaccharide powder:

[0032] extract:

[0033] 1. Weighing: Weigh 10.00g of spirulina powder into a 500ml beaker

[0034] 2. Dissolution: add deionized water into the beaker according to the ratio of solid to liquid of 1:25 (g / ml)

[0035] 3. Freezing and thawing treatment: Freeze at -20°C for 4 hours and take it out. Then thaw in a 37°C water bath, and repeat this 3 times

[0036] 4. Ultrasound: After thawing is complete, ultrasonic for 15 minutes at 80Hz

[0037] 5. Extraction: After the ultrasonic wave is finished, extract at 90°C for 3 hours under constant temperature reflux.

[0038] 6. Centrifugation: Centrifuge the extract at 3000r / min for 10min, take the supernatant

[0039] 7. Concentration: the extract is concentrated under reduced pressure at 70°C to obtain a concentrated solution

[0040] 8. Alcohol precipitation: Then use 95% ethanol alcohol precipitation with 5 times the volume of the concentrated solutio...

Embodiment 2

[0049] Embodiment 2: the preparation of cream:

[0050] raw material:

[0051] Caprylic Capric Triglyceride: Purchased from the Making Cosmetics website (trade name Triglyceride)

[0052] Tocopheryl acetate: purchased from the website of Making Cosmetics (the trade name is Vitamin E (dl-alphatocopheryl acetate)

[0053] Glyceryl stearate, macrogol-100 stearate: purchased from the website of Making Cosmetics (trade name BLEND)

Embodiment 3

[0073] Embodiment 3: stability test, see figure 2

[0074] Centrifugal test:

[0075] Process: Put the sample into a centrifuge tube with a 10ml scale to about 2 / 3 of the height, fill it firmly, plug it with a cover, and then put it into an electric thermostat incubator pre-adjusted to 40°C. After keeping it warm for 1 hour, two Put the centrifuge tubes into the centrifuge to maintain balance, and centrifuge at a speed of 2000r / min for 30min to observe whether there is oil-water layering or particles.

[0076] Result: No oily water layering, no particles.

[0077] Heat resistance test:

[0078] Process: Put the sample into a sealed centrifuge tube, place it in a constant temperature box at a temperature of 40°C for 24 hours, then return to room temperature to observe the discoloration of the liquid and the separation of oil and water.

[0079] Result: No oily water layering, no particles.

[0080] Cold Test

[0081] Process: Put the sample into a sealed centrifuge tube,...

Abstract

The invention discloses a preparation method of a composition containing spirulina polysaccharide extract. The raw materials of phase A are heated and dissolved, and the raw materials of phase B are heated and melted, then added to phase A, stirred while adding, homogenized, and then sequentially during the stirring process. Add the raw materials of phase C, homogenize, stir, and get it. Phase A includes: caprylic triglyceride, CreamMaker‑Blead, GelmakerEMU, vitamin E acetate; or includes: jojoba oil, CreamMaker‑Blead, avocado oil , cetearyl alcohol, vitamin E acetate, GelmakerEMU; Phase B includes: glycerin, sodium hyaluronate, deionized water; or includes: glycerin, sodium hyaluronate, sodium pyrrolidone carboxylate, 1,3-butanedi Alcohol, deionized water; phase C includes: spirulina extract, Budisma japonica extract, grape seed extract, spring elm extract, asiaticoside extract, benzyl alcohol‑DHA, essence. The product of the invention has good heat resistance, cold resistance and other stable characteristics, has good scavenging effect on DPPH and·OH, and has good moisture retention.

Description

technical field [0001] The invention relates to a preparation method of a spirulina polysaccharide extract product, in particular to a preparation method of a composition containing the spirulina polysaccharide extract. Background technique [0002] With the advancement of technology and the advent of more and more electronic products, people are also exposed to too much blue light. Compared with ultraviolet rays, blue light has stronger penetrating power and can directly reach the dermis of human skin, thereby causing damage to the skin. Such as oxidative stress, pigmentation, etc. In addition, it can also cause damage to retinal cells, resulting in vision loss or even loss. The damage caused by blue light also makes anti-blue light products more and more sought after by people. [0003] Spirulina is rich in polysaccharides, proteins, amino acids, vitamins, carotenoids, γ-linolenic acid, inorganic elements Na, K, Ca, Mg and trace elements Fe, Co, Mn, Ni, Cr, V, Zn, Se , ...
