Problems solved by technology

However, in the wet mask, since the mask essence is rich in nutrients, in order to store and retain physiological activity for a long time, a large amount of preservatives are added to the essence, and preservatives and surfactants are threatening to skin health.
At the same time, the residual microorganisms in the production process of the product will also affect the health of the skin. At the same time, some unstable but highly bioactive raw materials will attenuate in the mask, which is not conducive to preservation and exert their biological effects

[0060] 1, the preparation method of bletilla striata polysaccharide is:

[0061] (1) Bletilla striata (place of origin: Zhejiang) was dried and crushed into powder, and passed through a 100-mesh sieve. Add absolute ethanol to extract and degrease for 4 hours, filter with suction, repeat twice, and dry the filter cake under vacuum at 50°C. Accurately weigh and degrease Bletilla striata into a large Erlenmeyer flask, add distilled water, and the ratio of solid to liquid is 1:30( g / mL), extract in a water bath at 70°C for 3 hours, filter the filtrate with 4 layers of 200-mesh filter cloth, and repeat the extraction twice; after combining the filtrate, concentrate it to 1 / 4 volume by vacuum rotary evaporation at 65°C, and add absolute ethanol to the volume of ethanol in the system The fraction reached 80%, and stood overnight; the precipitate was obtained by suction filtration, washed with acetone and ether, and freeze-dried to obtain the crude polysaccharide of Bletilla striata. ...

Abstract

The invention discloses a polysaccharide whitening solid mask, a preparation method and application thereof. The method comprises the following steps: (1) preparing a facial mask liquid: mixing and stirring the raw materials of the facial mask liquid evenly, and then homogenizing to obtain a facial mask liquid; wherein, the facial mask liquid contains the following components by mass fraction: 5 to 50 parts of polysaccharide Composition, 0-20 parts of sodium hyaluronate, 0-5 parts of pearl powder and 20-95 parts of water; the polysaccharide composition includes Bletilla striata polysaccharide, Poria cocos polysaccharide and white peony polysaccharide; (2) Preparation of polysaccharide whitening solid mask: The cellulose mask paper is soaked in the mask liquid, then vacuum-dried until the mask liquid appears transparent, and then sterilized to obtain a polysaccharide whitening solid mask. The solid facial mask prepared by the invention has good moisturizing effect, can promote wound healing, has good tyrosinase inhibitory and antioxidative properties, and plays a positive role in regulating skin microbial state.

Description

technical field [0001] The invention relates to the technical field of skin care products, in particular to a polysaccharide whitening solid facial mask and its preparation method and application. Background technique [0002] With the improvement of people's quality of life and the pursuit of improving the overall appearance, beauty and skin care products are becoming more and more popular. Mask has become the most important part of skin care products because of its high nutritional content, remarkable skin care effect and convenient use. The mask uses the essence to cover the face for a short time, temporarily isolates the outside air and pollution, increases the temperature of the skin, expands the pores of the skin, promotes the secretion and metabolism of sweat glands, increases the oxygen content of the skin, and helps the skin to eliminate the metabolism of epidermal cells The products and accumulated oily substances, the nutrients in the mask penetrate into the stra...
