[0061] Another aspect of the present application discloses a preparation method of the moisturizing mask, including the following steps: preparing phase A, and then adding phases B, C, and D in sequence at different temperatures.

[0062] In an embodiment, the preparation of phase A is specifically as follows: water and disodium EDTA are added into a pot, stirring at 60 Hz, carbomer is added and stirred and heated to 75-85℃, and stirring is continued until the carbomer is dissolved and then the solution is added into a preparation pot; pre-dispersed butanediol and hydrolyzed sordariomycete collagen raw materials are stirred at 30 Hz until the raw materials are dissolved and then the solution is added into the preparation pot, and other ingredients are added into the preparation pot.

[0063] Preferably, heating is performed to 80℃.

[0064] In an embodiment, phase B is added into the preparation pot for continued stirring at 30 Hz and cooling to 55-65℃.

[0065] Preferably, cooling is performed to 60℃.

[0066] In an embodiment, phase C is added into the preparation pot for stirring at 30 Hz and cooling to 42-48℃.

[0067] Preferably, cooling is performed to 45℃.

[0068] In an embodiment, the solubilized phase D is added into the preparation pot for stirring at 30 Hz for 10 minutes, and the obtained solution is filtered through 200-mesh filter cloth after detection, and then the moisturizing mask is obtained.

[0069] Preferably, cooling is performed to 40℃.

[0070] The inventors found that the addition of the combination of solubilizers PPG-26-butanol polyether-26 and PEG-40 hydrogenated castor oil can improve the heat and cold resistance stability of the mask, and there are no abnormalities when kept at 40℃ for 24 hours or kept at minus 8℃ for 24 hours. The applicant believes that the possible reason is that PPG-26-butanol polyether-26 and PEG-40 hydrogenated castor oil can significantly reduce the surface tension and increase the solubility of other oily components in water, so that other oily components in the mask can be well and uniformly dispersed in the system. Even when the solubility or micellar properties of the system change in a relatively high temperature or cold environment, water and oil can be uniformly dispersed.

[0071] In addition, in the present application, wolfberry polysaccharide and skin conditioner C are added, and the skin conditioner C includes skin crystal, anthocyanin, wolfberry extract, biosugar-1, turmeric gel, and spilanthes extract, and the mass ratio is (0.8-1.5):(1-3):(0.05-0.2):(0.3-0.6):(0.4-0.6):(0.8-1.5). The effective components jointly act to significantly improve the efficacy of the moisturizing mask, and the moisturizing mask can greatly improve the moisturizing property of the skin, and avoid the skin peeling and dryness phenomenon in dry weather such as seasons. The reason is that the moisturizing agent used in the present application is mostly small molecular alcohol which can absorb water from the surrounding environment to improve the water content of the stratum corneum, but it is not suitable for use in dry winter. The wolfberry polysaccharide and plant extract added in the present application are rich in oil substances which can form an oil film on the skin surface to prevent water evaporation in the stratum corneum, play a sealing and moisturizing role, and are rich in active ingredients such as vitamin E which can repair the stratum corneum, improve the barrier function of the stratum corneum, reduce the water loss through the skin, and thus achieve the moisturizing effect and the effect of improving the skin luster. In addition, the present application ultimately obtains a misty flowing liquid prepared by the above method, which has good skin absorption and a pleasant smell.

[0072] Beneficial effects

[0073] 1. The inventors found that the addition of the combination of solubilizers PPG-26-butanol polyether-26 and PEG-40 hydrogenated castor oil can improve the heat and cold resistance stability of the mask, and there are no abnormalities when kept at 40℃ for 24 hours or kept at minus 8℃ for 24 hours.

[0074] 2、The goji polysaccharide and skin conditioner C are added in the present application, the skin conditioner C includes skin crystal, anthocyanin, wolfberry extract, biosugar glue-1, turmeric gel, spilanthes acuta extract, and the mass ratio is (0.8-1.5):(1-3):(0.05-0.2):(0.3-0.6):(0.4-0.6):(0.8-1.5), effective components act together, the efficacy of the moisturizing mask is significantly improved, the moisturizing mask can greatly improve the moisture retention of the skin, and the skin peeling and dryness phenomenon in dry weather such as season change is avoided.

[0075] 3、The raw material of the present application is safe, and has the effect of improving skin luster. BRIEF DESCRIPTION OF DRAWINGS
