DETAILED DESCRIPTION

High temperature heating is required to promote the solution, but high temperature heating itself will cause protein inactivation. If alkali is added to promote dissolution, it will affect the emulsification properties of the subsequent solution. Oat β-glucan has an immunomodulatory effect and can effectively improve human immunity. Oat β-glucan itself has excellent anti-aging function, which can smooth fine wrinkles, improve skin elasticity, improve skin texture, promote fibroblasts to synthesize collagen, promote wound healing, and repair damaged skin.

[0117] In Examples 1-7 of the present invention, an inner water phase, an outer water phase, and an oil phase are used to form a water-in-oil-in-water microemulsion, and oat protein is arranged in the innermost inner water phase. The isolation property of the microemulsion is used to preserve the oat protein. Compared with Control Example 1, the crystallization of oat protein caused by the presence of multiple other substances in the same solution with the oat protein is avoided.

[0118] Compared with the control example 2, the embodiments 1-7 of the present invention improve the solubility of the microemulsion itself by adding Tween, so that the oat protein can be stably dissolved in the inner water phase, the content of the oat protein itself is increased, and the subsequent facial mask's repair function for the skin is improved. However, since the control example 2 does not add Tween, when a large amount of oat protein is added, the solubility is poor and a small amount of suspended matter is present, which affects the use effect of the facial mask itself.

[0119] At the same time, Examples 1-7 of the present invention achieve mixed application of hydrophilic substances and lipophilic substances (such as oat kernel oil and coenzyme Q10) in the facial mask by setting up a microemulsion, so that the user can use the facial mask once during use to achieve the care of the hydrophilic and lipophilic substances on the facial skin, and by adding sodium hyaluronate to the external aqueous phase, the composite microemulsion has better water retention, and it itself has a certain viscosity and can adhere to the facial mask.

[0120] In addition, the raw materials of the embodiments of the present invention are all natural product extracts or edible substances, so that the composition itself is non-toxic and harmless and edible, thereby improving the safety of the facial mask.

[0121] In Example 1-7 of the present invention, the multilayer characteristics of water-in-oil-in-water of the microemulsion are utilized to add active substances such as natural extracts and oat protein into the inner water phase, and the inner water phase effectively preserves the active substances to prevent the presence of other substances from reducing their activity. In addition, by adding oat β-glucan, on the one hand, oat β-glucan itself has good beauty effects, and on the other hand, oat β-glucan is added to the inner and outer water phases to improve the overall emulsion stability of the microemulsion.

[0122] As can be seen from the above table, in the salting-out experiment, the microemulsions of Examples 1-7 did not show obvious turbidity changes, indicating that in the preparation method, the oat protein was dissolved in the inner water phase as a whole, while Control Example 1 was not a microemulsion, did not form a capsule structure, and could not preserve the oat protein well. Due to the components, Control Example 2 had insufficient emulsification performance and weak solubility, so that part of the oat protein was dissolved in the outer water phase, and did not have a good preservation effect on the active ingredients.

[0123] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, ordinary technicians in the relevant field should understand that after reading the specification of this application, the technicians can still modify or replace the specific implementation mode of the present invention with equivalents, but these modifications or changes do not deviate from the scope of protection of the pending claims of the present application.
