Embodiment Construction

[0043] In order to better illustrate the technical solutions of the present invention, the following examples are given, but the present invention is not limited to the following examples.

[0044] step one:

[0045] 1. Test

[0046]

[0047]

[0048] Sodium acetylated hyaluronate: the degree of substitution is preferably 3.5-4.0, and the molecular weight is preferably 10-100kDa. The selected examples in the above table have a degree of substitution of 3.9 and a molecular weight of about 50kDa.

[0049] 2. Membrane preparation method

[0050] Each embodiment prepares 100g solution respectively. Fully infiltrate sodium hyaluronate, acetylated sodium hyaluronate and hydrolyzed hyaluronic acid with glycerin, add purified water while stirring, heat to 50°C to fully dissolve, add betaine and other ingredients (when necessary), mix well, Coat it on a stainless steel plate with a thickness of 0.1mm, dry it at 50°C to form a film, the film is translucent, cut and pack.

Abstract

The invention relates to the technical field of hyaluronic acid, in particular to a hyaluronic acid skin care film. The hyaluronic acid skin care film is prepared from 12%-36% of hyaluronic acid or hyaluronate, 12%-30% of acetylated hyaluronic acid or acetylated hyaluronate, 12%-36% of hydrolyzed hyaluronic acid or hydrolyzed hyaluronate, 1%-30% of a moisturizer, 0-20% of an emollient, 0-20% of other active ingredients and 5%-15% of water. The hyaluronic acid and derivatives thereof are taken as main components of an instant soluble film, the mechanical property of the film is remarkably improved, the flexibility is enhanced, functions of a film forming agent, a thickening agent and a skin nutrition moisturizer and the like are integrated, and besides, the hyaluronic acid has an absorption promoting effect and a synergistic effect on the other added active ingredients; the product is small in size and convenient to carry and adopts a novel form.

Description

technical field [0001] The invention relates to the technical field of hyaluronic acid, in particular to a hyaluronic acid skin care film, and also relates to a preparation method and application of the hyaluronic acid skin care film. Background technique [0002] Instant film agents are usually composed of water-soluble film-forming materials, plasticizers, disintegrants, fillers, drugs, etc. Film-forming materials are the largest proportion of excipients in instant film formulations, accounting for more than 45% of the dry weight of film formulations. Among them, pullulan, gelatin and hypromellose are the most commonly used film-forming materials. Other commonly used film-forming materials include polycarbophil, cellulose derivatives, pullulan, xanthan gum, carob gum, guar gum, carrageenan, sodium alginate, chitosan, polyepoxy Ethylene, polyvinyl alcohol, etc. Different film-forming materials will significantly affect the mechanical properties and use experience of the f...
