Embodiment 1

[0041] The preparation method of polygonatum polysaccharide comprises the steps:

[0042] According to the ratio of 1g: 20ml, the pulverized Polygonatum odoratum powder was placed in water and soaked for 2.5 hours, then extracted in a water bath at 80°C for 1.5 hours, filtered, extracted twice, the combined filtrate was concentrated to 40% of the volume of the filtrate, To obtain a concentrated solution, add ethanol so that the volume concentration of ethanol in the concentrated solution is 72%, let it stand for 10 hours, centrifuge, discard the supernatant, dissolve the precipitate with a small amount of water, and freeze-dry to obtain Polygonatum polysaccharide.

Embodiment 2

[0044] The preparation method of polygonatum polysaccharide comprises the steps:

[0045] According to the ratio of 1g: 10ml, the pulverized Polygonatum odoratum powder was placed in water and soaked for 4 hours, then extracted in a water bath at 70°C for 2 hours, filtered, extracted 3 times, combined filtrates, concentrated to 30% of the volume of the filtrates, To obtain a concentrated solution, add ethanol so that the volume concentration of ethanol in the concentrated solution is 70%, let it stand for 12 hours, centrifuge, discard the supernatant, dissolve the precipitate with a small amount of water, and freeze-dry to obtain Polygonatum polysaccharide.

Embodiment 3

[0047] The preparation method of polygonatum polysaccharide comprises the steps:

[0048]According to the ratio of 1g: 20ml, put the pulverized Polygonatum odoratum powder in water and soak for 0.5 hours, then extract in a water bath at 95°C for 1 hour, filter, extract once, combine the filtrates, concentrate to 40% of the volume of the filtrate, To obtain a concentrated solution, add ethanol so that the volume concentration of ethanol in the concentrated solution is 73%, let it stand for 10 hours, centrifuge, discard the supernatant, dissolve the precipitate with a small amount of water, and freeze-dry to obtain Polygonatum polysaccharide.

Abstract

The invention discloses a moisturizing skin-care formulation containing complex polysaccharides and a preparation method of the formulation. The moisturizing skin-care formulation containing complex polysaccharides is made from the following raw materials in parts by weight: 0.2-0.8 of Polygonatum odoratum polysaccharides, 0.1-0.5 of algal polysaccharides, 0.1-0.5 of oat polysaccharides, 10-15 of oil and fat, 1-2 of a first emulsifier, 7-9 of a second emulsifier and 75-80 of water. The study proves that the moisturizing skin-care formulation containing complex polysaccharides has a certain antioxidant activity and can scavenge free radicals and reduce production of lipid peroxides. Therefore, the skin-care formulation containing complex polysaccharides is favorable to slowing skin aging and keeping the skin surface moisturized and has a certain effect of whitening the skin.

Description

technical field [0001] The invention relates to the technical field of cosmetics, in particular to a moisturizing skin care agent and a preparation method thereof. Background technique [0002] Judging from the development in recent years, the importance of moisturizers in cosmetics is increasing day by day. In the past, people mistakenly believed that dry skin was caused by the lack of lipids on the skin surface. Now, a large number of experiments have proved that applying oil on the dry skin surface does not Make it soft, because the real cause of dry skin is insufficient moisture in the stratum corneum, and moisture is absorbed by the stratum corneum by means of moisturizers binding water. Therefore, humectant is not only an essential raw material for skin care cosmetics, but whether it can be absorbed by the stratum corneum is a key factor that determines the quality of a cosmetic. [0003] At present, the most commonly used natural moisturizers such as hyaluronic acid ...
